View Full Version : Will GF8900 GTX Outpace R600?
I've got a question guys and I'm not being factious either. I've heard many people say that they believe the GF 8900 GTX will be faster than the R600. I don't understand how it's possible when the R600 looks to have better specs than the 8900 GTX.
For example, the R600 will have more transistors, but the two biggies are that the R600 will have a 512-bit memory bus vs 384-bit for the G81. The R600 is supposed to be clocked faster too. There are a couple more comparisons but I don't recall what they are. For the record I plan on buying the 8900 GTX mainly because the massive delays with the R600 and the massive power requirements as well.
That brings up another question. The R600 is rumored to use as much as 300 watts. http://www.hardocp.com/news.html?news=MjQ0MTcsLCxobmV3cywsLDE=
The G81 is supposed to use around half that. Looking at all this on paper, how can the G81 possibly be faster than the R600?? Personally, I really hope it is, but I just don't understand how that can be. I'm talking both DX9 and DX10 too.

Wasn't there a rumor that nV will skip the G81 (because of the new R600 delay) ? But they still have plans for the GX2 version...

I heard something to that effect and that they'll go straight to the G90, but I heard it will still come around the time the R600 does. Either way, it's not hurting Nvidia right now and I doubt the R600 will hurt Nvidia unless it's just a monster in performance in both DX9 and 10.

I'm sure R600 will be a very good card but R600 is way too late on the market to hurt nV IMO.

You should have known by now that theoretical performance and actual performance have nothing to do with each other. Take the 6800 Ultra and the X800XT-PE. The X800XT-PE was clocked faster, yet both cards were mostly equal in benchmarks. Take the 9800 Pro and the 5900. The 5900 was clocked higher but the 9800 Pro destroyed it in Dx9 applications. Even the 9700 did.
In the end, what matters is the architecture. Not the memory b/w, or fillrate, or triangle rate. Specs mean crap if your chip is handicapped by a design flaw. This can also mean that your chip might have a revolutionary design advantage while being well below your competitor's specs and come out on top.
No matter what the specs of the R600, I will wait for actual benchmarks before I pass judgement. Personally, I hope it will be well above the 8800GTX, because competition is good and that will only make Nvidia push harder. If companies try more to outpace each other, we consumers benefit from it.

If the R600 has 360 shader units, I still think it will be faster than the 8900.

Well, it should... :)
No one really knows for sure, but I expect R600 may well end up a bit faster than anything nvidia has. 8900 will likely keep it close enough that it doesn't matter all that much. Ultimately the choice between them will come down to features and driver quality, imo.

if that was the case we would have been hearing a **** load of leaks about how supperior it is to the g80. remember, devs had this card months ago and we would have heard something about it by now regarding its performance from multiple sources if this was the g80 killer.

ok ok, doesnt anyone stop to realize how stupid it is to even say nvidia is going to release the g90 right now. thats a next gen part. each generation takes years of dev and simulations time to develope. so were lead to believe nvidia can release a next gen part in a matter of months, not years now.

Are we sure developers have had cards for a while? And even if they do have them, what makes you think it's final silicon at final clock speeds, it could be clocked much lower than the launch version. We didn't know all that much about the G80 until about a month before launch, either. We know some vague specs for the R600 but nothing solid for performance. Both companies have gotten better at managing leaks lately. The absence of information is just that- it doesn't imply what's going to be better, either way.

G90 doesn't really say much. 6800 to 7800 wasn't a big jump in terms of technology, it was essentially a revamp of the same architecture. G90 or whatever they release in the fall is likely the same deal.

you know that the 6800 series was code named nv40 and the 7800 series was code named nv45 or g70, they were within the same series. usually when you go from one code name (nvx0) to another they usually denote a whole new generation? the generations take any place from 2-3 years to development and simulation time. so i dont think they are going to push for the g90 just yet.

The article said 320 IIRC.

isn't that what we have been hearing? What about those leaked benchmarks (though I believe them to be fake)? What about all the information that the technology powering the R600 can blow the G80 away (320 shaders, insane memory bandwidth, etc).

For every rumor that says it destroys the G80, there is another rumor that the performance is faster in some apps, and slower in others.
Really, just no one knows at this point. It all depends on the efficiency of the architecture; its looking like the R600 has some crazy clockspeeds... is this to destroy the G80? Or keep up with it? It depends on the architecture.
Remember, AMD said that they are "repositioning" their R600 card. What does that mean? Food for thought.....

And the only reason they changed their code nomenclature for chips was to get them in-line with the marketing series.
In other words... G70 = geforce 7 series. G80 = geforce 8 series. G90 = geforce 9 series, which everyone expects to be an updated version of the G80 architecture, just like the 7 series was an update to the 6 series.
That means unless they change their naming conventions again, G90 won't be a new generation card, it'll be G80 take 2.

G80's shaders are on a different clock domain.... if ATI's shaders are clocked lower, they're going to need more to keep up. Again, they'll likely have more raw horsepower, but probably not by as wide a margin as some people think.

If it's a next-gen part like Nvidia was talking about i.e. the multi-core chip design then no, but if it's another single core chip design then I think it could be. Just look at the R520 and then the R580 was released only a couple months after the R520, so there's no reason Nvidia can't do the same.

.....mmmmm...not another multi-core rumor crap again....cant we just kill this one already.

8800 Ultra won't be the fastest 8800.
8800GTX is.
8800 Ultra won't be the fastest 8800.
8800GTX is.
based on what? the "ultra" monikor has always denoted the highest of the high.
New quadro FX5600 PCB with 1.5Gb GDDR3 and 171W PR.
Hope be the same with 8800 ultra PCB
