You honestly believe that 5x90 cards will be slower then GTX285 SLI and 4890 CF? Do you know something the rest of us don't?Quote:

I think you have a very optimistic view on HD5870 performance. 10-20% isn't enough to catch GTX 285 SLI.

I think ATI is more worried about beating out the 295 with their single chip refresh, not SLI 285s
Why would AMD be concerned with an EOL part?
295 is the only 200 series still in production (other than that weird eVGA 275 + G92) and they would be concerned because it beats out the 5870 in 80% of titles.Quote:

It could be a new architecture but it remains to be seen whether it'll be more efficient than Cypress on the same node.
well yea when the 5870 refresh hits the 295 will definitely be EOL on production. I wonder what happened to the ASUS Mars 295s; did one person buy like half of them or did they all melt and weren't able to RMA due to limited production?
if we're stuck on 40nm for 2010 this means that there isn't going to be a 5990 like previously hinted
It's enough to catch a 295 that everyone keeps mentioning in this thread. GTX285 SLI is 59x0 territory.Quote:

295 and 285 SLI are only 10-15% different in speed (since the 295 is 2x 275) unless you game at huge resolutions and the memory bottleneck on the 295 is exposed. However this only happens at above 1920x1200 with full IQ.Quote:

That's not what I'm trying to say. In fact I'm not sure I'm even interpreting this mess of words correctly.Quote:
You're just contradicting yourself. Up above you state the 5x90 will compete with gtx285 SLI, and there won't be a 5990 or a 5790 (that competes with gtx285 SLI), that leaves the 5890 which will NOT compete with it like you previously quoted.
You're just contradicting yourself.

5990?
If they already hit the PCI-e 2.0 TDP limit with the 5970 and had to lower both mem and core frequencies to stay below 300W, the 5990 it's very unlikely to happen (unless they use 32nm for the 5890? which is even more improbable :D).
Didn't you know about the unwritten rule that you have to predict the most favorable outcome for AMD and the worst possible outcome for Nvidia? :p: The 32nm 5990 will be with us right quick!
I agree that it is becoming increasingly hard for both ATI and Nvidia to keep their dual GPU solutions within 300W. That doesn't necessarily mean that they won't make a >300W 5990 if NV threatens their market position with Fermi.Quote:

IT LOOKS LIKE we were right about Fermi being too big, too hot, and too late, Nvidia just castrated it to 448SPs. Even at that, it is a 225 Watt part, slipping into the future.
Update: Nvidia has contacted us and declined to respond.
The main point is from an Nvidia PDF first found here. On page 6, there are some interesting specs, 448 stream processors (SPs), not 512, 1.40GHz, slower than the G200's 1.476GHz, and the big 6GB GDDR5 variant is delayed until 2H 2010. To be charitable, the last one isn't Nvidia's fault, it needs 64x32GDDR5 to make it work, and that isn't coming until 2H 2010 now.

eee if this is true....it does not bode well.
:shocked:
I thought that site was going down? It spurs utter BS on a daily basis.
What would be the point of that? Didn't you just dismiss the hard numbers posted a little earlier and went on to predict great driver improvements for Cypress and crap drivers for Fermi? Seems you have it all sorted already.Quote:

What would be the point of discussing it instead of sarcastically beating up strawmen? To explore the topic from a different point of view perhaps? Or do you expect me to play devil's advocate against my own perspective as well?Quote:

You want my optimistic perspective? The most (realistically) optimistic performance figures I have heard for Fermi are 40% faster then evergreen. Let's say that ATI doesn't refresh the 5xxx series either so they have to compete with what they have. If that happens performance would probably, IMO, look something like: 5850 < 5870 ~= GTX360 < GTX380 < 5970 < GTX390
That's basically a redux of last generation. As such it would probably mean some more market share erosion and narrow margins for Nvidia, just like last gen. That's my optimistic view. If you wanted me to say NV would be king of the universe and there would be global peace I'm sorry, I just don't think it's going to happen.
Actually it's spot on: http://www.nvidia.com/docs/IO/43395/...83-001_v01.pdf Unless you doubt the source...Quote:

I hope they didn't really get so much hallucinated to forget the gaming part.
