ATI Aiming For R300 Deja-Vu: Officially Launches 4800 Campaign

[Seraphiel]

Also 280GTX got 240 SPs, 4870 got 160 before you apply marketing.

Does the 4870 really have that many? I thought, they had a 1:5 ratio, in term of their FUD about SP count? R600 had 320 SP / 5 = 64 SP vs G80 GTX/Ultra that had 256 SP / 2 = 128 SP

I thought, the 4850 / 4870 only really had 96, increased from 64, but still with more execution units per SP than nVIDIA ... 1:5 vs 1:2.

In terms of execution units ... GTX 280 and 4870 is the same: 480(1:2) vs 480(1:5). Meaning 240 SP for nvidia and 96 for ATI, and there is the clock difference.

I thought, ATI's 320 SP for R600 was FUD and not the same as nVIDIA's 128 SP, which has two execution units (and counted as ATI does, that would be 256 SP).

Please someone explain.
