Now that we've seen the NV40/R420 series in action & we already knew that the NV45/R423 is appearntly going to have the same specs (or even lower) except for the PCI-E transition ... i think its time to discuss the NV48 & the R480's specs , names , power .. etc !
Well i'll strat with my humble speculation :
NV48 is going to be a speed bump for the NV40/NV45 & of course is going to be PCI-E with HSI bridge so it may get transformed into AGP 8X if needed .
Enhanced Cooling solution & the same Power requirments will be the highlights of NV48 i guess .
Speculated Specs :
222M Transistors
DX9.0 support / SM3.0
0.13u Process (with Low-K?)
16x1 pipelines
500Mhz core clock (Up to 550Mhz using Low-K?)
1300Mhz Memroy clock
512MB GDDR3 VRAM
Product Name : GeForce 6900 Ultra
Performance over NV40/NV45 ~ 15-20% (30%@550Mhz)
The same pattern will go with the R480 i reckon .
R480 will be PCI-E only & might use a whole new or enhanced cooling solution with a bit higher power reqs (400W PSU i presume) .
Specualted Specs (EDITED):
160M Transistor
DX9.0 support / SM2.0+
0.11u process
16x1 Pipelines
600Mhz core clock
1250Mhz Memory clock
512MB GDDR-III VRAM
Product name : Radeon X900XT
Performance over R420/R423 ~ 10-15%
Thats all in case the new NV48/R480 are just speed bumps for thier predecessors .
however , in case the NV48/R480 appeared to be a whole new architecture .. there will be a different story ;-)
