Nvidia unveils the GeForce GTX 780 Ti

[iMacmatician]

This isn't a panicked reply to the 290X, there has been talk of TITAN Ultra for a while now and this is it. That screenshot is certainly fake, it has more CUDA cores than that. The memory speed is also wrong.

These cards are going to walk all over the 780 and TITAN.

2880 CCs and 7 Gbps memory?

2880 CCs and 7 Gbps memory?

... and 1,500 dollars!

2880 CCs and 7 Gbps memory?

Hmmm...

[boxleitnerb]

I was under the impression that the 780 Ti and the Titan Ultra were different things. Which cards will become EOL?

[[XC] Oj101]

TITAN is going to be EOL.

TITAN Ultra never had an official name, now it does.

Well that is exciting. Titan EOL, who would have thought that......

I can't say I'm surprised though, they did have long enough to anticipate things, especially since the focus has already been on Maxwell for some time.

3 GB or 6 GB? Would be weird to downgrade from Titans memory amount. But $649 for > Titan performance would be quite uncharacteristic of Nvidia, even more so with 6 GB.

Thanks Oj101 !

What do you mean by walk over ? 15-20% better than Titan ?

I'm really curious about this card, but I think I'm turning back to AMD this time.

My last 2 vga purchases i really try to get a nvidia for cuda development also wanted physx for games but amd both times offered a better bang for buck deal. Especially the last one. I decided to but 680 without a doubt but amd came with game bundles and i immediately change my decision. If amd was 1 day late today i will be using a 680.

Now my idea changed. 5870 then 7970 both times i wanted an nvidia but amd's offer changed my mind. But this time i want an amd so nvidia should came with an offer like it's bundle.

3 GB or 6 GB? Would be weird to downgrade from Titans memory amount. But $649 for > Titan performance would be quite uncharacteristic of Nvidia, even more so with 6 GB.

Also what about the DP rate? If the 780 Ti has 1/24 DP rate like the 780 then that would also be a downgrade relative to the Titan.

On the memory, maybe there could be 3 GB and 6 GB official variants, like the 460-768 and 460-1024 (but with no bus width or ROP changes)?

Well, DP is irrelevant for gamers, isn't it? Both cards bear the GeForce label, not Tesla or Quadro

But... Titan is already an idiotic purchase for games outside of a few extreme situations. However it's a really cheap way to get things you'd normally have to get a Tesla or Quadro to get. Nvidia even pushes the cards GPU computing prowess as a reason to buy one.

The best justification for Titan is that you play games and want to do some other stuff that would normally require Tesla or Quadro products. At that point it starts looking like an amazing deal.

780 Ti is 3 GB.

I don't think the 780 Ti having a low DP rate would be a problem - it wasn't with the 780 either. Having 3 GB vs 6 on Titan and 4 on 290 and 290X would be, though.

Afaik, Titan was a spontaneous creation (AMDs Crysis 2 deal, cough) more for marketing reasons than for anything else.

780 Ti is 3 GB.

Damn. Partner models with 6 GB allowed? If not, Nvidia is shooting themselves in the foot, especially with SLI in mind.

[[XC] Oj101]

The 780 Ti isn't tied down the way TITAN was. 3 GB should be AMPLE for most people, there's no reason to have to charge more for the small handful of people that might need it. Hell, last year (or year before, time goes so quickly...) I was gaming at 3840x1080 on SLI'd GTX 580s (1.5 GB cards).

[PedantOne]

Thanks Oj101 !

haha, no way. It is only few percents above titan

So you mean partners have greater leeway with the 780 Ti?
If you only have one card, 3 GB is enough. But with 2, 3 or 4...I'm not so sure. Especially if you want to keep them for some of those next-gen games which might use more memory.

But at what resolution. If it does use faster memory, we should see improvements at higher resolution compared to titan. Exactly where it needs it the most to compete against r290x. If they use 7ghz ddr, they should in theory have more bandwidth than a 290x.

If they are open about the cooling on the card and the mods like they were with the gtx 780, then they have a monster base for performance increase.

At the same clocks as titan, they should be somewhere along the lines of 5-12% faster because of 7% more shaders and 16.7 percent more bandwidth. Add in 100-150mhz OC models like gtx 780, and you have a card that is 25 percent faster than titan at high resolutions.

In gaming tests, higher factory OC cards like the gtx 780 HOF or lightning are already 10% faster than titan, add in 25 % more shaders and more bandwidth and you should have something that performs like a gtx 690 or 7990.

Hold onto your seats for the Hall of Fame, SuperOverclock, Classified (unconfirmed), Lightning and more - it's going to be a bumpy ride over the speed bump affectionately called TITAN

[boxleitnerb]

Lol! But they couldn't go too far with those OC versions, unless Nvidia somehow improved efficiency. Titan@1 GHz already draws 250W, 265 if you have to increase power- and temperature targets to get there. What Nvidia really really needs to do is to raise the stock targets...80?C is just not enough, the card would get stuck at base clock almost all the time.

Edit:
Is the 780 Ti by any chance based on GK180? It seems that GK110 cannot be used to enable all 15 SMX. K40 and probably K6000 use GK180 and both have the full 2880 cores.

They can do whatever they want. Power consumption isn't an issue with the HD 7990 and GTX 690 requiring 300W+. At this point, the problem is heat.

If we examine the specs between gk110 based k20x tesla, the clocks of the cards were only 732 mhz, yet it had a rated tdp of 235watts. Pretty low clocks, but GK110 based titan still goes to 876mhz(even more in practice).

Look at GK180 based K6000 and you have a card that is clocked at 900mhz, has more shaders and has a tdp 10 watts lower TDP than k20x. That's a massive improvement. Before you say they aren't comparable since Tesla is different than the workstation quadro, lets look at the fermi generation.

Tesla M2070 and Quadro 6000 are both based on the same GF100 and if you look at the clocks, they are exactly the same at 574mhz and not only that, they have the same TDP at 225 Watts. They have the same clocks and TDP rating

So now lets look at GK110 to GK180 again for the professional class of cards.

732mhz -->900mhz
2688 shaders --> 2880 shaders
235watt TDP --> 225 watt tdp

Now lets fill in the blanks for titan to gtx 780 ti
876mhz --> ????
2688 shaders --> 2880 shaders
250watt TDP --> ???

So if any of GK180's improvements carry over, even just a little bit(and they used GK180 instead of Gk110), then you have room for monster clocked cards, just as much as gtx 780 if not more.

The 900mhz clocks and 225 watt TDP on a fully enabled big keplar is very impressive for quadro.
