NVIDIA GeForce GTX 780 Review: The New High End
by Ryan Smith on May 23, 2013 9:00 AM ESTBattlefield 3
Our final action game of our benchmark suite is Battlefield 3, DICE’s 2011 multiplayer military shooter. Its ability to pose a significant challenge to GPUs has been dulled some by time and drivers, but it’s still a challenge if you want to hit the highest settings at the highest resolutions at the highest anti-aliasing levels. Furthermore while we can crack 60fps in single player mode, our rule of thumb here is that multiplayer framerates will dip to half our single player framerates, so hitting high framerates here may not be high enough.
Battlefield 3 is another game that NVIDIA traditionally does well in, despite the fact that both sides have wrung out some rather impressive performance increases over the last year. At 2560 the GTX 780 enjoys a 33% lead over the 7970GE, a 27% lead over the GTX 680, and a massive 85% lead over the GTX 580. Furthermore this is fast enough to get it past 60fps at 2560, which means our minimum framerates should dip no lower than the mid-30s even in the most hectic multiplayer maps.

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?
