They could codename their 8970 Tahitan xD

So prices won't change until AMD comes out with their new cards. Might as well buy as soon as possible then.
GTX 780 performs the same as the Titan in almost all games when both are overclocked.

so what will happen eventually is that AMD makes enough money off of those other sources, and we will be stuck with Nvidia's high prices until then. Maybe AMD isn't even concentrating on gaming performance as much since their cards are better at compute performance, like nvidia cards used to be until they started to optimize gaming cards for fast game rendering. And that's why AMD is behind release right now with GCN 2.0 like someone else said they have had plenty of time with 28nm.

Sure, if you count 5-10% slower being "the same"... rolleyes.gif
Max 10fps difference for games that perform at above 100fps anyway.

It's kind of hard to find comparisons between the titan and gtx 780 because different sites use different settings. And I'm not interested in sites with the same settings used but no overclock because of how easily you can overclock these cards. And the sites that do overclock only do it for one card.

Does someone have a way to make a jpg out of this spreadsheet including the comments on the tiles?

You can see that neither are overclocked very much, but if the GTX 780 was overclocked more it would perform more similarly to the Titan.

You know it's a pity we still talk about average FPS, we should always consider minimum FPS into the picture as well.

If the average FPS is 100, but every 10 seconds it drops to 10 frames once, you will notice and feel it. That's why I really started enjoying the new way of testing graphical cards - frame latency included, along with the rest!

Yeah I know. But I can't find any tests with minimum frame rates where I can compare them to separate cards. But usually what I've seen with these higher end cards right now is that the minimum FPS increases or decreases the same amount as the average FPS. At least for the more graphically intensive games.

very likely it is something I dislike though I want the core to be universal.
post #278 of 465
All I can say is that it will be interesting to see final specs and pricing vs. 700 series. Unfortunately both AMD and NVIDIA are guilty of pricing their stuff high when they can get away with it. The only thing that kept me from getting a 7970 the day it released was the $550 price tag. Don't kid yourself, if they can get away with it, both companies will price gouge.

But definitely looking forward to what AMD puts out and see what that does with overall pricing.

This is true to an extent. Pitcairn (HD7870GE/HD7850) , Bonaire (HD7790), and Cape Verde (HD7770/HD7750) only have 1/16 FP64 performance , which is still better than Nvidia's 1/24 FP64 on everything Kepler except GTX TITAN. Cayman (HD 6950/HD6970) had 1/4 FP64, Cypress XT HD5870 had 1/5 FP64 whereas Tahiti is 1/4 FP64.

It's only fair 7790 has 1/16th the FP64 to FP32, it belongs to the "8770" series i think

Kepler has FP64, it's just 1/24. So a GTX 670 has about as much as a HD7790 Warning: Spoiler! (Click to show)
In GK104 none of the regular CUDA core blocks are FP64 capable; in its place we have what we’re calling the CUDA FP64 block.

The CUDA FP64 block contains 8 special CUDA cores that are not part of the general CUDA core count and are not in any of NVIDIA’s diagrams. These CUDA cores can only do and are only used for FP64 math. What's more, the CUDA FP64 block has a very special execution rate: 1/1 FP32. With only 8 CUDA cores in this block it takes NVIDIA 4 cycles to execute a whole warp, but each quarter of the warp is done at full speed as opposed to ½, ¼, or any other fractional speed that previous architectures have operated at. Altogether GK104’s FP64 performance is very low at only 1/24 FP32 (1/6 * ¼), but the mere existence of the CUDA FP64 block is quite interesting because it’s the very first time we’ve seen 1/1 FP32 execution speed.
