Just been looking around the net and ive found some more infomation about the N35 Chip Geforce FX
The NV35 will presumably run at a slower core/memory clock speeds than the NV30, but it doesn't mean it will be inferior to its predecessors, a fact pointed out by the Inquirer.
While clockspeeds on the new chip haven't yet been finalized, we've heard 450 / 850 (core/memory clock) suggested as the likely final numbers, or something close to them. If true, this means NV35 will run a 10% slower clock and a 15% slower memory core than its predecessor, and in raw numbers, ends up looking a lot like the original GeForce FX 5800 (which, if you recall, didn't require such mammoth cooling solutions either).
This isn't the first time Nvidia has released a next-generation card running slower than the previous. The GeForce3, if you'll recall, ran a slower clock then the GeForce2 Ultra, yet proved itself a far superior solution in the end, and we'll be surprised if something similar doesn't happen with NV35 compared to NV30. Even with a slower memory clock, NV35 is going to offer far more bandwidth than NV30 ever did — along with slowing down the memory and switching back to DDR I, Nvidia is copying ATI and using a 256-bit interface to power their latest creation—which, we're told, will be called the GeForceFX 5900 Ultra with a projected retail price of $499. There will also be a GeForceFX 5900, which will retail for a price of $399. We've been told the two cards are identical in core speed, but the 5900 Ultra will carry an additional 128 meg of RAM (for a total of 256).
Ordinarily at this point we'd say something about how having a card named the 5800 Ultra and the 5900 Ultra is a bit confusing, given how massive the differences between NV30 and NV35 truly are. While ATI's Radeon 9700 and 9800 both use an identical naming scheme, the 9700 is still a card people actually would want to own. In the end, it’s a moot point for Nvidia — since no one could buy GeForceFX 5800 Ultra's there's precious little worry they'll end up confused with the 5900 version.
At this point, with Nvidia's 5900 Ultra likely to take over or at least compete for the driver's seat, ATI has some interesting options. If the 5900 Ultra isn't that much of a stretch over the 9800 Pro, or merely competes with it they can elect to do nothing and things continue on as they have. If NV35 does present a threat to the Great White North's dominance of the video card market it's got two choices — either raise the clockspeed on the existing Radeon 9800 Pro or release the card in a MAXX dual-processor version.
The idea of a Radeon 9800 MAXX isn't as far-fetched as it might seem as the architecture of the chip is designed to be linked in up to a 256 GPU system. While I don't think we'll be seeing any 256 chip solutions from ATI, a dual-solution with 256 meg of RAM total (128 for each processor) could boost current Radeon 9800 performance by an approximate 50-70%. Such a card would be expensive, but it'd also likely stuff Nvidia quite nicely.
Of the two options a speed boost is by far the more likely, but until we see final NV35 benchmarks we won't even be able to hazard a guess as to how much of a performance kick ATI might want or need to give the 9800. With its .13 micron process there should definitely be some headroom left in the R350 design but with NV35 looking much better than its predecessor, it may not be enough. ATI may be left playing second-fiddle again, at least until R400 and NV40 square off.
:happy:
