So, what might NV34 be?

[megadrive0088]

a refresh of NV30/GeForce FX or a different model? Obviously NV31 is a low-end/mainstream version but what could NV34 be?

Although NV34 is probably not GeForce FX2, I guess there is an outside chance it is and that it would be ready in H1 2003.

Or perhaps it's just a higher end GeForceFX.

If it is GeForceFX2 however, this would be roughly the time that the chip would have to tape out, would it not? Assuming the refresh is not late, like the NV30 was.

when did NV15/GeForce2 GTS tape out? It must have been shortly after GeForce256 arrived on shelves was it not?

NV34 is a new nForce chipset with NV3x core integrated. I think it will be basically an integrated NV31 chipset with dual channel memory controller, but it must be a WAY slower than NV30 and even NV31 unless JEDEC approves DDRII DIMM modules by that time, because memory speed is four-fold less even when using PC2700 DDR SDRAM...

ahhh thanks for the clarification on NV34

NV34 - IF being NForce chipset, which is just rumors as far as I know - might only feature two pixel pipes. All other NForces have only had two, and 1/4 amount of pipes on 1/4 amount of bandwidth will balance out. Of course, it won't balance out since there will be a CPU, plus all the southbridge devices stealing bandwidth, but in theory anyway it will balance. And 200MHz DDR DIMMs or even faster might be available by that time thus alleviating the shortage somewhat.

I think 2 pipes in NV3x-version of NForce is a reasonable assumption, considering they eat up the bulk of the chip real-estate in NV30. Fewer pipes = much smaller chip = cheaper chip, and since motherboards can't cost fourhundred freakin dollars and have a cooler capable of handling the Tchernobyl reactor... Well, you do the math, k?

NV31 is probably the moneymaker. My cynical mind see's Nvidia taking a loss on the nv30 (clocked high for pride and marketing sake) in small volumes and coming back with a slightly lower clocked version 2 for mass production. IMHO no high volume OEM will put anything with that kind of HSF in their box.

if what i think is true, dont be worried about mem bandwidth.... look for my thread im about to make

 

[megadrive0088]

bandwidth. hmmm. if ATI moves to GDDR-3 with the 256 bit bus it already has, at it's current core speed, that would be almost 40 GB/sec raw bandwidth, more with a higher clocked core.

Nv... if NV35 has 256-bit bus with DDR-II and well beyond 500 Mhz core, holy **** that's going to be alot of bandwidth in 2003, provided R350 and NV35 are out next year.
