NVIDIA GeForce GTX 780 Review: The New High End
by Ryan Smith on May 23, 2013 9:00 AM ESTSleeping Dogs
Another Square Enix game, Sleeping Dogs is one of the few open world games to be released with any kind of benchmark, giving us a unique opportunity to benchmark an open world game. Like most console ports, Sleeping Dogs’ base assets are not extremely demanding, but it makes up for it with its interesting anti-aliasing implementation, a mix of FXAA and SSAA that at its highest settings does an impeccable job of removing jaggies. However by effectively rendering the game world multiple times over, it can also require a very powerful video card to drive these high AA modes.
Sleeping Dogs is another game where the 780 fills out a gap, but falls closer to the 7970GE than NVIDIA would like to see. At 64.4fps it’s fast enough to crash past 60fps at 2560 with high AA, but this means it’s narrower win for the GTX 780, beating the GTX 680 by 23% but the 7970GE by just 7%. Meanwhile the GTX 780 trails the GTX Titan by 12%.
The minimum framerates, though not bad on their own, do not do the GTX 780 any favors here, and we see the GTX 780 fall behind the 7970GE here by over 10%. Interestingly this is just about an all-around worst case scenario for the GTX 780, which has the GTX 780 trailing the GTX Titan by almost the full 15% theoretical shader/texture performance gap, and the lead over the GTX 680 is only 10%. Sleeping Dogs use of SSAA in higher anti-aliasing modes is very hard on the shaders, and this is a prime example of what GTX 780’s weak spot is going to be relative to GTX Titan.

so, how many Double Precision units are there in each SMX unit of gtx780? titan had 64 dp units in each of their SMX units which totaled to 896 dp unitsAnd can u turn them on or off from the forcewre driver menu like “CUDA – Double Precision” for gtx780?

Hardware wise this is GK110, so the 64 DP units are there. But most of them would be disabled to get the 1/24 FP64 rate.aidivn - Friday, May 24, 2013 - link
so how many are disabled and how many are enabled (numbers please)?Ryan Smith - Friday, May 24, 2013 - link
You would have only 1/8th enabled. So 8 per SMX are enabled, while the other 56 are disabled.aidivn - Saturday, May 25, 2013 - link
so, the GTX780 only has 96 DP units enabled while the GTX TITAN has 896 DP units enabled...thats a huge cut on double precisionDanNeely - Sunday, May 26, 2013 - link
That surprised me too. Previously the cards based on the G*100/110 cards were 1/8; this is a major hit vs the 580/480/280 series cards.Old_Fogie_Late_Bloomer - Thursday, May 23, 2013 - link
"GTX 780 on the other hand is a pure gaming/consumer part like the rest of the GeForce lineup, meaning NVIDIA has stripped it of Titan’s marquee compute feature: uncapped double precision (FP64) performance. As a result GTX 780 can offer 90% of GTX Titan’s gaming performance, but it can only offer a fraction of GTX Titan’s FP64 compute performance, topping out at 1/24th FP32 performance rather than 1/3rd like Titan."Seriously, this is just...it's asinine. Utterly asinine.

Market segmentation is nothing new. The Titan really is a steal if you need DP, the next card up is 2400 dollars.Old_Fogie_Late_Bloomer - Thursday, May 23, 2013 - link
I'm well aware of the existence of market segmentation, but this is just ridiculous. Putting ECC RAM on professional cards is segmentation. Disabling otherwise functional features of hardware, most likely in the software drivers...that's just...ugh.SymphonyX7 - Thursday, May 23, 2013 - link
I just noticed that the Radeon HD 7970 Ghz Edition has been trouncing the GTX 680 in most of the benchmarks and trailing the GTX 680 in those benchmarks that traditionally favored Kepler. What the heck just happened? Didn't the review of the Radeon HD 7970 Ghz Edition say that it was basically tied with the GTX 680?
