New rumor about ATI Southern Islands

[RPGWiZaRD]

I think he's right !

I really don't see HD6870 performs worst than HD5870 (or HD6850<HD5830 ...) if not, it's a big naming mistake from AMD.

Well it won't happen if the floating around specs are correct at least, 960 SPs (60% less than 5870) and 850MHz core clock. Ofc there is the 4D shader array change and possibly other changes we don't know about yet but that there would be over say 35~40% increase in performance efficiency from internal changes I really have a hard time believing for Barts. I would be happy/satisfied if it can beat HD 5850 with such specs, that would be quite an accomplishment already with that amount SPs.
