780 ti in modern games. Video cards

The seventh series of video cards from NVIDIA ruled the market for a very short time. Only in the spring we were shown the GTX 780, which remains a very fast video card today. But AMD recently released a new line of graphics cards, and NVIDIA couldn't stand aside. No, we are not being offered a new line yet. We are offered a new video card - NVIDIA GTX 780Ti, let's talk about it. To begin with, we will look at the slides from the official presentation, and then we will move on to the torture of the video card itself and the comparison with its direct competitor - AMD R9 290X.

What is the GTX 780Ti graphics card? NVIDIA identifies four main factors. Now we have 25% more CUDA cores, namely 2880 pieces. This is nice, because now we have a full-fledged GK110 GPU without blocked modules.

The second highlight is the initial clock frequency of the video memory of 7000 MHz. It's really a lot. Apparently, in this way NVIDIA is struggling with the 512-bit memory bus of its competitor AMD R290X. The fact is that monitors with support for 4K resolution (3840 x 2160) have recently appeared. In this resolution, the memory bus is very heavily loaded, requiring a large bandwidth. Of course, it is obvious to everyone that monitors with such a resolution will not be in demand for a very long time, since the price for them today is about 150 thousand rubles. Even if in a year it drops to 50 thousand, monitors still will not be a bargain. For a very long time, monitors with a resolution of 2560 x 1440 have been on the market for 20 thousand rubles, but even they are too expensive for most buyers. And if the user can somehow save up money for a new expensive video card, understanding what exactly such a new thing will give him, then the monitor for most players is not a paramount thing. But the arms race in ultra-high definition combat has already begun and is unlikely to be stopped.

In addition, NVIDIA offers us GPU BOOST 2.0 technology, which very accurately selects the most stable clock speed. The fourth bonus is the power subsystem, which works very accurately, thanks to which we can count on good overclocking potential.

On this slide we are shown the superiority of NVIDIA GTX 780 Ti over AMD R9 290X. You immediately pay attention to the “GFLOPS” parameter, which literally rises above the competitor’s result by a millimeter. Especially when you consider that the graph is not built from zero.

NVIDIA GTX 780 Ti Performance

Judging by this slide, the GTX 780 Ti video card unconditionally wins in power consumption. We are told a TDP of 250 watts. This is not much for a performance card. In addition, the GTX 780 Ti is noticeably colder, and, according to NVIDIA, only warms up to 83 degrees. Good, we'll definitely check it out.

And here are the measurements of gaming performance. Everything here is good for NVIDIA, and not so good for AMD. In most modern games, the novelty wins from 10 to 50%. This is a serious statement, let's see what happens in reality.

Features look very impressive. The number of stream processors is 2880, which operate at 875 MHz, and GPU BOOST increases the frequency to 928 MHz. Memory bus 384 bits, memory type GDDR5. The clock frequency of the video memory is 7000 MHz. TDP 250 Watts, the card is powered by one six-pin and one eight-pin connectors.

To sum up, the NVIDIA GTX 780 Ti is faster, cooler and quieter than the AMD R9 290X. We will definitely measure each of these parameters, and now let's move on to the video card itself.

NVIDIA decided not to come up with a new design for the GTX 780 Ti, but to use the same one that NVIDIA TITAN had. On the one hand, when you buy a new product, you want the appearance to be new. Of course, the main thing lies under the heat-distributing cover, but people still buy with their eyes. On the other hand, NVIDIA has clearly found a very successful design that does not age and, if I may say so, is timeless. He's just smart and stylish.

The entire body is made of aluminum, which gives the video card a solid weight. In the center there is a transparent plastic window through which you can see a massive radiator. True, it is beautiful exactly until the moment when the radiator is not clogged with dust. And self-opening the card for cleaning threatens to void the warranty.

The video card is equipped with four video outputs: one HDMI, one DisplayPort and two DVI. All four connectors can be used at the same time.

On the top edge of the video card there are two additional power connectors, one six-pin and one eight-pin. The name of the graphics card is LED backlit and glows beautifully in the dark. Another small design plus.

There is absolutely nothing interesting on the back of the video card. Is that a few tantalum capacitors.

The design of the printed circuit board has not changed either, almost all elements have remained in the same places as in NVIDIA TITAN.

In the center of the board, we see the GPU itself, labeled GK110-425-B1. Around it are twelve video memory chips with a total volume of three gigabytes. Why only three? Good question. For this video card, it would be just right to have six gigabytes of video memory, since it is aimed at fighting at high resolutions.

The power subsystem has not changed and operates according to the 6 + 2 scheme, where 6 phases are assigned to the video processor, and two more phases are given to the video memory.

The cooling system rests on many small screws, which are popularly called asterisks. In the center of CO, we see a small polished area, which is in contact with the GPU itself. Video memory chips and elements of the power subsystem transfer their heat to the radiator through thermal pads.

This concludes the study of the video card and proceed to the table of technical characteristics.

The differences between the regular GTX 780 and the GTX 780 Ti are quite noticeable. Here and an increased number of cores, an increased number of texture units and an increased clock frequency of video memory. And if AMD's new R9 290X overtook the usual GTX 780 in almost all applications, then the alignment of forces is likely to change here.

Overclocking and temperatures

Rumors circulated long and hard on the Internet that a full-fledged GK110 would overclock well. The fact is that previous NVIDIA cards usually showed mediocre overclocking, without outstanding results until a serious change in cooling. We'll test overclocking the GTX 780 Ti with stock cooling and see if it surprises us.

So, the stock clock frequency of the video processor is 875 MHz. In self-overclocking mode, we are promised up to 928 MHz. But NVIDIA paid special attention to GPU BOOST 2.0 technology. Let's check how the clock frequency of the video processor actually is under load. The load was created by the 3DMark 13 benchmark.

The clock frequency was always at around 1020 MHz. It is worth noting that this is a very high-quality and serious benchmark that loads the map completely and does not let it relax. Especially since we ran it in Extreme mode. Therefore, here we got exactly what the card really can do, without the influence of the crooked code of some toy.

Such a result cannot but rejoice, especially considering that this is a stock cooling system. And the clock frequency of new video processors in auto-overclocking also depends on temperature. Speaking of temperature. We got the maximum value of 78 degrees, which is very good.

We will overclock the video processor at the standard voltage without making any changes to the operation of the entire device as a whole.

The video processor was able to function stably at a frequency of 1126 MHz. This is a very good indicator. Relative to the stock 875 MHz, we received an increase of 251 MHz. This is indeed a very good result, especially considering stock cooling and native voltage. Let's see what the real frequency is under load. Video memory overclocked to 8000 MHz. This is also a very high figure.

The actual clock speed was firmly at 1270 MHz. What can I say, this is a great result. Frankly, we expected to get no more than 1100-1150 MHz. NVIDIA has really released a great GPU. If you change the cooling system to a more efficient one and increase the voltage on the video processor, the result can exceed all expectations. The temperature at the same time increased only to 81 degrees.

As for the temperature in the popular FurMark utility, we got the following results. Under load at nominal value, the card warmed up to 84 degrees, which is only 1 degree more than NVIDIA promised.

Under load in acceleration, we got all the same 84 degrees. The fan speed increased from 59% to only 61%. Of course, the noise level has not changed, which is very nice. It should be noted that the card does not make any noise under load.

A new version of GeForce Experience - 1.8 has become available on GeForce.com. In addition to new profiles, updated settings, and some other new features, GeForce Experience 1.8 includes the much-anticipated GeForce ShadowPlay gaming image capture tool.

Fast, free, and simple, ShadowPlay is a new approach to gameplay recording powered by the NVENC H.264 hardware encoder built into the GeForce GTX 600 and 700 series GPUs.

Shadow Mode continuously records gameplay, saving 10 to 20 minutes of play to a temporary hard drive buffer. If you've done something amazing, just press Alt + F10 to save that memorable moment to the right folder. To prevent clutter of video files on the hard drive, ShadowPlay saves the file only when hotkeys are pressed.

The saved footage can then be edited in popular editors such as Sony Vegas, Adobe Premier, the free Windows Movie Maker or any other .mp4-compatible video editor, and immediately uploaded to YouTube. You can also upload the raw file to YouTube first and then edit it with the built-in tools. In future versions of GeForce Experience, ShadowPlay will be integrated with the Twitch.tv online service, which will allow ShadowPlay users to send recorded files directly to Twitch.

ShadowPlay uses the H.264 hardware encoder built into the GeForce GTX 600 and 700 series graphics cards to record at 1920x1080 at 60 fps. All games using DirectX 9 or later versions of this interface are supported. Compared to software solutions that use CPU resources to record gameplay, GPU hardware encoding reduces performance by only 5-10% when recording videos of maximum quality at a bit rate of 50 Mbps. With automatic H.264 encoding, compression and MP4 recording, ShadowPlay prevents huge multi-gigabyte files from cluttering up your hard drive.

If you want to record your entire game session, select manual mode using the Alt + F9 key combination - in this mode, the tool works similarly to traditional applications for recording gameplay. In the case of Windows 7, due to the nature of the OS, the file size is limited to 4GB, but in Windows 8 and Windows 8.1, the file size is limited only by the availability of hard disk space, so you can easily create hours of video.

Immediately after the release of the beta version, NVIDIA released an update that includes the following changes/additions:

Win7 removed the 3.8 GB file size limit.
Record game video up to 20 minutes in Shadow mode.
Unlimited manual recording.
When a file reaches 3.8 GB, ShadowPlay creates new files.
Record video without rescaling up to 1080p. At higher resolutions, the aspect ratio is preserved.

Added microphone recording.

The NVIDA GTX 780 Ti video card won an unconditional victory over the AMD R9 290X. There is not a single game that the 290X wins. Note the huge performance boost in overclocking.

Conclusion

The NVIDIA GTX 780 Ti video card proved to be a very high-quality product. She is fast, cold and good looking. Performance in all tested games was higher than that of the AMD R9 290X. Particularly pleased with the excellent overclocking potential. The video processor functioned stably at a frequency of 1270 MHz. This is a very high rate, which is rare. It is worth noting that the card was overclocked on a stock cooling system and nominal voltage. In light of this, I really want to see something like the ASUS GTX 780 Ti DirectCU II TOP. It is likely that such a video card will be able to submit to a frequency of 1350-1400 MHz.

I was somewhat surprised by the amount of video memory - only three gigabytes. Although it is worth recognizing that even in UltraHD (4K) resolution, this volume should be enough for all modern games.

The video card turned out to be very cold and completely silent, which is doubly pleasant. Even FurMark couldn't get the card above 84 degrees when overclocked.

All this suggests that we will soon be shown another modification of the GTX 780 Ti video card, the clock frequency of which will be under gigahertz, the memory will be 6-12 gigabytes and the memory will function at 7500-8000 MHz. If such a video card sees the light, then we are even afraid to imagine how much they will ask us for it. After all, the usual GTX 780 Ti costs today in Moscow stores from 24,000 rubles.

The video card wins an Editors' Choice award.

Let's take a look at NVIDIA's line of video cards. GeForce GTX 770, GTX 780, GTX Titan and GTX 690 - a slightly wrong, but understandable classification of the company's accelerator lineup. But the GTX 780 Ti? What for? Where? With what to compare? The answer is not as simple as it might seem at first glance. If you think about it...

The sixth series of GeForce was extremely clear: each next-ranked model was distinguished by a large number in the title. And then there are video cards with an index that includes 7x0. At the same time, the GTX 690 has not disappeared anywhere, it still remains the fastest dual-core solution. Maybe the GTX Titan wormed its way into the wrong group? Well, why not, because he came to the gaming market from the world of calculations and remains the ultimate offer for both gaming and computing.

The question arises - should NVIDIA remove it from production after the release of the GTX 780 Ti? The answer is also simple. What for? It is popular with those who need computing and enthusiasts, however, for games, the GTX 780 Ti should be the best choice. This is because users are finally provided with a fully functional GPU with 2880 stream processors. Yes, only now after certain changes, which will be discussed below, the GK110 GPU is ready to join the gaming applications and show what it can do.

Probably, everyone is wondering why the GK110 got a new name, or rather the B1 stepping, and not say A2? It is believed that the numbers indicate fixes in the metal connections inside the GPU. The letters refer to changes in the transistors themselves. In any case, there are no radical changes inside the crystal - it's still the same GK110. All NVIDIA had to do was to adapt the full version of the GK110 to the required heat dissipation at the calculated frequencies, and this was not easy to do.

The secrecy of the company's developments is covered with such a veil of secrecy that it is almost impossible to get intelligible answers, you will simply be bombarded with advertising or general phrases from which it is impossible to find out the technical data. Well, secrets must be kept undisclosed, even under sharp questions from the press. For our part, one can only guess what tricks had to be used to fit the new GPU revision into the allotted power consumption range.

Technical features

As you already understood, there are no physical changes in the main logic circuits. Perhaps there are optimizations inside that reduce the time it takes to complete tasks inside the GPU, which leads to a smaller amount of simultaneously working transistors. This scheme of work has existed for a long time and is called "dark silicon". All 7.1 billion transistors operating at the same time cannot be cooled by any system, which means that you constantly need to monitor the balance, on the one hand of which is performance, and on the other, frequency, power consumption and the temperature resulting from them. The better and more economical the shutters work, and the lower temperature is kept, the faster the calculations occur.

Even before the advent of Hawaii from a competitor, NVIDIA introduced several provisions for the operation of the GPU. So, the base frequency is the lowest level of GPU operation, GPU Boost is the average GPU frequency in games. Most often, even after a long stay of the video card under gaming load, GPU Boost kept the GPU frequency slightly higher than stated. AMD has gone the other way - the only mode in which the video card fully realizes its power is "Normal" or, as it is also called, Uber mode.

But unlike the competitor, NVIDIA believes that the user does not need to deal with either the BIOS switches or the settings in the drivers - the video card will do everything for them, and by itself. And what can really be reproached by the GeForce developer is that the fixed power consumption limit is too close to the factory setting. It remains to be seen whether the engineers really solved the general problem of a sharp increase in energy consumption?

Appearance and dimensions

NVIDIA has decided to introduce another video card based on the GK110 chip, most likely the last one. This time around, the GeForce GTX 780 Ti uses a full version of the "Kepler" architecture, which will continue to dominate the market until "Maxwell" arrives next year. Judging by numerous rumors, the idea of presenting such a video card was born by NVIDIA quite a long time ago. Since the advent of the corresponding Tesla and Quadro graphics cards, it has become clear that a desktop graphics card is just around the corner. The new GeForce GTX 780 Ti can be seen as a response to the AMD Radeon R9 290X, but in any case, we have a new NVIDIA flagship. The GeForce GTX Titan video card gives way to the GeForce GTX 780 Ti. But how much faster will the novelty work compared to Titan? Or compared to the Radeon R9 290X? In our article, we will answer all these questions.

But before we move on to the last chapter in Kepler's life, let's take a little trip back. On March 22, 2012, NVIDIA introduced the GeForce GTX 680 graphics card, the first model based on the new "Kepler" GPU architecture. The streaming multiprocessors known from the "Fermi" architecture have been improved in the GK104 from 32 to 192 CUDA cores, now they are called SMX clusters. However, the changes affected not only the increase in the number of cores, but also the proportions of the control logic and computing units - in the new generation, the emphasis was shifted to computing units. Eight SMX clusters of 192 CUDA cores each resulted in a total of 1536 cores.

For almost a year, NVIDIA continued to optimize the "Kepler" architecture. As a result, in February 2013, the GK110 processor was released, containing up to 15 SMX clusters with 192 CUDA cores, which gave 2880 cores. But for the GeForce GTX Titan and the subsequent GTX 780, fewer SMX clusters were used: 14 and 12, respectively. Here, it seems to us, the reason was the difficulty of manufacturing chips, since a die with 7.1 billion transistors and an area of 533 mm² is not easy to produce without errors on the 28-nm process technology. Even during the presentation of the first desktop video cards based on the GK110 chip, there were rumors about the possible release of the "GeForce GTX Titan Ultra". And today this video card has finally appeared.

Before we get into the details of the GeForce GTX 780 Ti, let's talk about the specs.

Of course, the standout feature of the GeForce GTX 780 Ti is the GK110 processor in its full version. It is equipped with 15 SMX clusters, each with 192 CUDA cores, for a total of 2880 CUDA cores. The graphics processor is manufactured using a 28nm process technology, contains 7.1 billion transistors in an area of 533 mm². NVIDIA, unlike the latest "Hawaii" graphics cards from AMD, decided to set the base GPU frequency to 876 MHz, but thanks to GPU Boost, dynamic overclocking is provided to at least 928 MHz. According to NVIDIA, most video cards in practice easily reach the 1 GHz bar. We get a second NVIDIA graphics card with a high frequency of GDDR5 1750 MHz memory. It is connected via a 384-bit interface, resulting in a memory bandwidth of 336 GB / s. But NVIDIA decided not to equip the video card with 6 GB of video memory, unlike the GeForce GTX Titan, you get only 3 GB. Perhaps the situation will change after the release of the first video cards with alternative cooling systems, so the GeForce GTX 780 Ti with 6 GB of memory and even more may appear on the market. After equipping the Radeon R9 290X and 290 4 GB of memory, such a move seems quite logical to us.

The new GPU is equipped with 15 SMX clusters, which corresponds to 2880 CUDA stream processors and 240 texture units (there are 16 of them per SMX cluster). The 384-bit memory interface is paired with 48 raster operations pipelines (ROPs). According to the manufacturer's specifications, the theoretical pixel fill rate is at least 42 Gpixel/s. Up to four GeForce GTX 780 Ti graphics cards can work in SLI configuration. Unlike high-end AMD graphics cards, the new NVIDIA graphics cards still require an SLI bridge to work. But the situation may change in the next generation. The thermal output (TDP) is still 250W, which could be another advantage over the Radeon R9 290X, whose TDP exceeds 250W.

Comparison with competitors, both in-house and AMD, points to the theoretical advantages and disadvantages of the GeForce GTX 780 Ti. The number of stream processors outperforms the competition not so much, NVIDIA's memory bandwidth is slightly higher. But AMD's memory size, Boost frequency, and pixel fill rate (due to the higher number of raster operation pipelines) are higher. However, PowerTune and GPU Boost technologies today have a significant impact on performance, which is difficult to assess on theoretical specifications. So a comparison of theoretical computing performance, memory bandwidth and other technical characteristics is hardly relevant. The test results will show how far the new graphics card can break away from the GeForce GTX Titan and Radeon R9 290X.

Appearance and dimensions

Due to the release of the AMD Volcanic Islands family of video cards, a hard boom began in the graphics adapter market. Nvidia even lowered the prices of their top graphics cards, but that didn't help either. I had to do something and somehow change the situation in my favor. We needed a special model that would take the flagship - AMD Radeon R9 290X and removed it from the list of competitors.

In principle, nVidia has such a video card - this is the GeForce GTX TITAN. This is the fastest video card on a single chip at the time of release. But its price is too high and for most it is simply inaccessible. Even not every gamer decides to buy one. After all, for this money you can easily buy a good computer with excellent performance.

And now, nVidia has finally released a video card that is better than its competitor from AMD and more affordable - the GeForce GTX 780 Ti. She also became the head of the GTX 7xx family of video cards.

It can be assumed that this is a kind of trump card that the greens kept up their sleeves. A certain pause was simply waited for and the right moment was chosen for the release.

Specifications

Three out of fifteen large blocks from the Kepler architecture - streaming multiprocessors - were returned to this video card. It is much more powerful, especially in terms of shader instructions and texturing.

It also supports 7 GHz video memory, thereby increasing the bandwidth by as much as 14%.

Comparing the 780 Ti with its competitors, you can understand its pros and cons. For example, the number of streaming processes is not much different from others, but the throughput is still slightly higher. But here AMD has a much higher amount of video memory, Boost frequency and pixel fill rate. Now it is PowerTune and GPU Boost that greatly affect performance. And it is not so easy to evaluate it. So comparing all these basic characteristics is not so important.

Overclocking and tests

Overclocking the GTX 780 Ti is something. The video card has significant hidden reserves.

The company's engineers did their best. Due to a more advanced chip and an improved power system, you can overclock it by 200 MHz without raising the voltage.
