Edit: But probably not. 'Cause stuff like a 512-bit bus tend to be a one way ratchet at the high-end. . .you'd look pretty silly if your 90nm G70 had less bandwidth. . .or the gen after that.

Well, it is possible that the R520 will be a broken architecture, though unlikely. But we know that the G70 is not, and thus it just won't be outclassed by a similar amount to the NV30.

R520 being broken or not doesn't really matter at all. It's too late to make any impact even if it should end up being faster than G70. NV will prolly have their next chip out there until R520 arrives.

I can't find the post now, but I said it some 6 months ago that nV will rip ATI a new one this time around (without any insider infos). And that's what they did already by releasing the G70 a few months ahead of ATI's product. I bet they knew what's going on at ATI and thus went the low-risk route, holding their faster chip back a few months (32 pipes? 90 nm? Double core? Whatever... ).

I love being right

The next generation, from both companies, should be arriving late next year.

But nVidia may put out a higher-performing 90nm version of the 7800 GTX at a similar time to ATI's release of the R520, though I rather doubt it. I'm willing to bet that the 7800 GTX will stay where it is in nVidia's lineup, though the price may be adjusted to meet ATI's offering, and we'll just see nVidia start to replace their current NV4x lineup with lower-end versions of the G70.

The price will be adjusted, if R520's launch MSRP is lower than what G70 currently costs.

Agreed on the rest; late 2005 (or even early 2006) sounds like R580/Gxx@90nm time to me also.

Theoretically there are many sollutions for many bottlenecks; it just shouldn't cost an arm and leg for each specific timespan. If IHVs will move to wider buses, then maybe during the WGF2.0-era.

[Hellbinder]

what in the heck....

Page 48 and people are still talking about 16 "pipes" 24 "pipes" and 32 "pipes".....

I am like in the twilightzone or something.

GTX is not even 24 "pipelines".. it's 16/24.

You guys have got to get off this pipeline thing. The R500/c1 has 3 "pipelines" if you want to get technical.. but it is more powerful than the 520 or the G70.


16 (1-3-1)... at 600+mhz

has everyone forgotten this already?

[Hellbinder]

oh you guys are forgetting features as well...

and Chalnoth.. It would be logical that R580 will launch before the end of the year to counter any souped up GTX...

I think that when this is all said and done everyone is going to be plesantly suprised by what Ati releases.

Where's that ROFLMAO smiley?

hmm pipelines really doesn't matter with the r520

IIRC, NVIDIA said a long while ago that they expected a 512-bit bus to appear around the timeframe of the NV60. But what that timeframe was, nobody knows for sure anymore, saldy.

We heard that the last R520 spin at TSMC is at 3% yield rate for 24 pipes and we can certainly expect a much lower yield for 32-pipes R520. Obviously ATi is still facing some yield issues for their R520 @ 90nm process and ATI could resort to a 16 pipes R520 for better yield and make up the loss with a much higher core clock of 700MHz+ as INQ has previously suggested. It is still possible for ATi to keep to the time frame of August-September launch if decided to go ahead with 16-pipes R520. If not, 24-32 pipes R520 is expected to delay further to Q4 this year.

Gee, Digi, where ya been the last three pages? :?

[Chalnoth]

Is it just me, or does digi seem a little bit too happy with this news?

[Mendel]

Nah, don't you worry, it's just ethe good old digi. Always cheering when Ati does badly. Such an Nvidia fanb0y he is!

[Tim Murray]

This is the worst thread ever.

[Neeyik]

It's also ground itself out now, I think. Start up a new one when there's some better or more recent news.
