Default ATI HD4890 will be on 55nm , overclocked RV770

What move will AMD take to fight back? RV790 has aroused interest from lots of people as well as 40nm RV740. According to our source, RV790 will be named as Radeon HD 4970, with core clock improved to 950MHz (compared with 750MHz on HD4870). The memory clock keeps unchanged as 900MHz (i.e.3600MHz GDDR5). Based on 55nm manufacturing process, RV790 will come with 800 stream processors just as RV770, not 960 ones as rumored.

With massive 27% improvement of core clock, RV790 targets directly at GeForce GTX285. Maybe you would think AMD is confusing us on purpose like what they did to RV770, but the informer believe there won’t be much change in specs.
