AMD To Launch Radeon HD4890 "RV790" In April

[Hornet331]

Still just the supposed 6% increase, which was assumed due to the previous rumor of a 20% increase in performance over RV770.
A few Vantage benches also seemed to point to a IPC increase with scores of a RV770 @ 820mhz compared to the RV790 @ 850mhz.

Well vantage is quite the most irrelevant thing ever.

The preeleminary benches from pconline dont show this gains.
All lower then 13% beside vantage, and ~13% is the increase in clockspeed on core and ~8% on mem which also adds a couble of % to the all over performance gain.

I dont think the 4890 is worth the upgrade for anyone who owns a HD4870 or 260GTX, espeicla with the option of a soft/bios voltmod for those cards.

Better wait for the 5 seriers.

Will try and get Clock for Clock and Max OC vs Max OC
