Usually it is customary to start articles about the new generation with enthusiastic words about progress, future, beautiful graphics and speed records … but not this time. The output of the "seven -hundredths" in the composition GTX 780 And GTX 770 – This is the planned upgrade GTX 600 , The beginning of which was laid GTX Titan , three months ago.
Le version
We will not walk around the bush and immediately say, GTX 780 is not a new architecture, but a slightly trimmed and noticeably cheaper Titan. The card is based on the same chip GK110 , but not with 14, but with 12 SMX blocks. That is, the number of CUDA yaders decreased from 2688 to 2304, and textures-from 224 to 192 units. There were two times less memory: only 3 GB GDDR5 is installed in the GTX 780, but on the same bus at 384 bits and speeds of 6008 MHz. But the frequency of the GPU itself compared to the senior counterpart has grown a little: the base number is now 863 versus 837 MHz, and the dispersed is 900 instead of 876 MHz. Funny, but GTX 680 She worked 100 MHz faster, however, she could boast of only 8 SMX sets-she had a computing nuclei with one and a half times less.
Note that GK110 for GTX 780 is done on the principle of blocking faulty sections. Because of this, the number of GPCs (large blocks that combine three SMX-set) can vary from four to five, depending on which part of the crystal has not passed the check. However, we, end users, should not worry this fact. The following is much more important: together with the GK110 in the GTX 780, all Titan technological advantages came in the previous series.
Technologies
The first and most important feature is Turbo Boost 2.0 , Automatic acceleration algorithm. If the GTX 600 knew how to raise frequencies depending on current energy consumption, then the GTX 780 operates with temperature indicators. While it is held within 80 ° C, the speed grows as exceeded – it drops. As a result, the chip is longer in the BOOST position than before, and the final performance does not depend on the advanced application, but on how well it “breathes” in the body of your computer.
I came to GTX 780 and adjustable V-Sync, which allows not to limit itself to stable 60 FPS and receive up to 120 frames per second. According to rumors, professional e -sportsmen, this function is very to their liking.
New items
Fortunately, the GTX 780 did not cost the already known achievements, some innovations appeared, however, program type. First – the utility is now rolled up with the drivers GeForce Experience , replacing traditional Nvidia Update. At launch, it scans the system for the presence of games and offers for each found project, and even sets it independently, optimal graphics settings.
The combinations of the parameters are recruited not from the bay-beam and not by the command of the left heel, but on the basis of numerous tests carried out inside NVIDIA (one of the computer centers, by the way, is located in the Moscow office of the company). How useful such a thing is, it's hard to say. For people who understand the importance of anti -aliasing and how complex lighting affects GPU workload, the novelty is unlikely to benefit. But those who are weakly imagined how MSAA differs from TXAA, GFE will have to taste. The only thing is that the program so far sins with oddities and is too often trying to sacrifice the maximum resolution for the sake of some smoothing.
Against this background, the second innovation looks much more interesting. GFE includes a utility Shadowplay , able to capture the gameplay and turn it into a video of the 1080p format. To the honor of NVIDIA, the function is correctly implemented. GPU and CPU resources are not used: Nvenc video decoding Block with support h is chased into a video card H.264. In simple words, a drop in performance is minimal. In the pluses, the fact that writing videos for several hours is not necessary; You can turn on cyclic work and save, for example, only the last 20 minutes of gameplay, just like on the PlayStation 4.
Appearance
With the appearance of the GTX 780, they did not get wise, they took the GTX Titan shell and put another marking on it. As a result, we have the same metal shell with a transparent window and a luminous inscription “GeForce” on the side.
The cooling system is assembled on the basis of copper evaporative chamber and two massive aluminum radiators. One cylindrical turntable is responsible for blowing, taking the air from the body and driving a stream through the entire fee.
Note that the dimensions of the card are average – only 26.6 centimeters in length. To work, she requires two power plugs for 6 and 8 PIN, providing 250 W Energy. Set of connectors standard: two DVI and in full -size HDMI with DisplayPort.
Tests
The test stand for the new product was collected on the basis of the motherboard MSI Eclipse Sli , Installed a processor on it Core i7-920 and three ranges Kingston Hyperx DDR3-2000 MHz 2 GB each. Operating system, Windows 7 Ultimate Edition 64-bit , and all service on the hard -own war Kingston SSDNOW volume of 64 GB. All test programs launched from the classic hard drive Seagate Barracuda 7200.10.
The Synthetics set of our standard 3dmark 11 , Unigine Heaven Benchmark 4.0 And Unitine Valley 1.0. But we have updated the game list. Besides already well -acquainted Aliens vs. Predator , Crysis 3 And Batman: Arkham City , They entered the ranks Bioshock Infinite , Tomb Raider, Hitman: Absolution And Metro: Last Light. They didn’t really suffer with the settings for them: the top card, which means, all the sliders are maximum, and on the way.
Competitors
It turned out to be more difficult to select competitors. In fact, GTX 780 simply does not have. The card was estimated at 23,999 rubles and put between the GTX 680/Radeon HD 7970 and GTX Titan. So no direct comparison, only price/performance ratio.
Unfortunately, we failed to pull out all the necessary tests for testing. GTX 780 launched too rapidly, and we could not find HD 7970 in such a short time. However, the loss is small, in terms of price and capabilities, the “red” leader is very close to the GTX 680. So far, you can focus on the results of the latter, and in the near future we will definitely update our signs.
We have small problems with Titan. And although the map hit our test stand in time, for some reason she could not open up. The processor struck at a minimum frequency of 836 MHz and flatly refused to at least somehow accelerate. And this is when the GTX 780 and GTX 680 worked with pleasure at the increased 1020 and 1030-1080 MHz, respectively. Bottom line: Our Titan, for some reason, worked more slowly than a deliberately weaker GTX 780.
However, you should not worry about this. We already drove the flagship in the company with GTX 680 and GTX 690, and it will not be difficult. Moreover, on the scale of the map speed, more than neatly are located.
In all tests, the GTX 780 is approximately 15-20% faster than its predecessor. In this case, the increase is not as ephemeral as it might seem. In the same Crysis 3, Metro: Last Light and Tomb Raider, it allows you to get an “extra” ten fps and pull up projects to a really playable level, without any “yes with 25 frames is comfortable”. But from two GK104 on the GTX 690, the novelty is already noticeably lagging behind-from 14 to 36%-which means that Titan is inferior, although not so many, about 6-8%.
In the end
You can relate to GTX 780 in different ways. On the one hand, it is strange when the leader of the just created line is not an unconditional flagship. On the other, Titan has become cheaper almost one and a half times – it's great. Especially given the drop in performance by only 6-8%.
As for whether or not to buy a new product, let's say so. She has no competitors, so if there is money, take. No – take a closer look at the models easier. The same GTX 680 looks very cheerful and, if you do not wave it on the MSAA 8x, lightly pulls all new games. Much more interesting here the question “what's next?". With GTX 770, which will be officially presented in about a week, everything is clear. She, apparently, will wedge between the old and the new leaders of generations, but what will happen later is not known.
