Rage3D has published an article about the architecture of the RV770, the latest GPU from ATI.

As an opener to our launch day coverage, we’ll be taking a plunge into the RV770 and seeing what what is new, what has changed, what stays the same (quickie note: not much) and how it all fits together. We’ll be following pretty much the same structure that Scott Hartog, chief architect for the RV770 series, used in his presentation of the architecture, as it nicely flows from one aspect of the new chip to another, using Richard Huddy’s R600 architecture overview for comparisons and underlining the differences between chips. We’ll also check and see if we can actually achieve the theoretical numbers using a number of synthetic tests … don’t worry, the whole gaming enchilada will soon follow, we haven’t lost our focus.

TG Daily has published an article about the details of the upcoming ATI Radeon 4800 series.
In terms of performance, we heard some interesting claims. A 4870 should perform on par with or better than a dual-chip 3870 X2. Our sources explained to us that using a PCIe Gen1 controller 3870 X2 was a mistake, since the board was hungry for data and didn’t sync well with this interface. Don’t expect the ATI team to repeat that mistake with the 4870 X2. However, we admit that we have no idea what kind of connection two RV770 GPUs will have.
The Radeon HD 4850 powered by the RV770PRO GPU will be launched on June 18 and the Radeon HD 4870 (RV770XT) is delayed on June 25.
La Radeon HD 4850 propulsée par le GPU RV770PRO sera lancée le 18 Juin tandis que la Radeon HD 4870 est retardée jusqu’au 25 Juin.
