AMD To Launch Radeon HD4890 "RV790" In April

[Nedjo]

They cannot create a shader core with 1000SPs. It is 960 or 1040SPs.

why not?

280 to 285 is 20% more or less so why not?

it's more "of" and much less "or"

RV790 sounds like the R520->R580 refresh than a new node at this point

and that was a quite of refresh:

thisHD4890 is in my hands ...NOW and perf is higher only 10 percents above HD4870 1GB! Great improvement Great AMD! GTX 260 216 still better!

My own Sample of RV 790 is "like 4850" with clocks 850/900 MHz ... better model (like today 4870) with 950/975 MHz could be later, but maybe will never be launched !

shaders are not that important actually, RV770 has a good amount of raw power, it needs more texturing power IMO, thats the bottleneck of the chip

WRONG LOE
