[Chip] More GTX780 Details - Page 4

post #31 of 132
Interesting, but I am taking this with a grain of salt. I remember all of the hype when the 6xx series were coming out and all the hype that surrounded those cards. Not saying 6xx aren't great cards I just don't think we will realistically see a 50% over 680 like some people are saying. I think we might see 25% with 15-20% being the most realistic number.

This is the exact same rhetoric that was coming from Nvidia one year ago to prevent people from buying AMD who had beaten them out with the new generation.

I bit the bullet with a 670. I'm gonna wait for the maxwell series. thumb.gif

Realistically, I think so too. ~15% at release and around 20-30% once drivers have matured. 680 at release was about ~15% faster than the 580.


With driver optimizations over the course of this year, a reference 680 is now about ~25% faster than a reference 580.

That's not how percentages work tongue.gif

In the first graph the 680 is around 20% faster than a 580 and in the second one it's about 32% faster. You're comparing it to the 580 when you say faster than a 580.

Those aren't completely valid as DX9 and DX10 games are skewing the relative performance in favor of the GTX 580.

I find 15% hard to believe.

http://www.overclock.net/t/1323188/ocuk-7950-crossfire-vs-680-sli-at-5760-1080-eyefinity-surround

If you see this chart, the 7950s at 1150/1700 are more than 20% faster than the GTX 680s in some games (eyefinity resolution). I know this chart is kind of biased since it includes AMD games to increase the gap further between the two cards but still if the GTX 780 is only 15-20% faster than GTX 680 it will still lose to the HD7950s which is hard to believe. Nvidia will lose a lot of the trust of their customer base if they do so.
Don't forget Nvidia is not targeting only the GTX 680 of this generation. They are aiming to defeat the HD7970 GE (fastest current single card) and that is already 10-15% better at higher resolution . So 40-55% increase in some games is not that hard to believe especially with resolution increase.
If they didn't reach their expectations with GK114 as a high-end part, they can easily use GK110 and eliminate or easily keep up with the competition thumb.gif .

I seriously doubt a Kepler refresh is going to bring about ~50% more performance. 15-25% is my bet. It'll be very similar to the jump from a 480 to a 580 which at release was 11% faster Warning: Spoiler! (Click to show)
15% at release I think is perfectly feasible...

You are correct. I was calculating it from the 680 perspective. In which case it should have read the 580 is around 15% slower than the 680 in the 1st graph and around 25% slower than the 680 in the second graph. I stand corrected.

I'm thinking the gap will be about 30%, the same margin that the GTX 680 is over the 580 and that is only regarding GK112. GK110 should bring another 20% still. I don't feel like doing the numbers again.
