AMD Radeon HD 4800 series technology analysis @ Elite Bastards

[news 28]

 

Hi everyone,

 

While the Radeon HD 4850 launched early last week due to boards slipping out into the retail channel, today is the true big day for AMD's next-generation graphics architecture, as the lid is lifted on their flagship Radeon HD 4870 part as well as the technology which powers the RV770 core utilised by these boards. To that end, in this article we delve into AMD's RV770 architecture, to see both what it offers over its predecessors and also how it marks a sea-change in the way AMD will be competing in the 3D graphics performance race from now on.

 

 

AMD Radeon HD 4800 series technology analysis

 

"Starting out with the basics of the core being launched officially today, we find that RV770 follows AMD's previous RV670 part in using the latest 55 nanometre manufacturing process. While this part can't quite reach the billion transistor level sported by NVIDIA's GT200 core, it isn't all that far off, with a total transistor count of 956 million, against the 666 million transistors used by the Radeon HD 3800 series.

 

This increase in specification and transistors also sees die size increase over RV670 as you would expect, with RV770 clocking in at 260mm squared against the 190mm squared die of RV670. This still absolutely pales into comparison with the vast die size of NVIDIA's GT200, which weighs in at absolutely massive 576mm squared."
