AMD shows off die shots of Southern Islands GPUs

Hexus noticed AMD released high-resolution die shots of its current-gen Southern Islands GPUs at the Hot Chips conference.

First up is Tahiti, the Radeon HD 7900 series part:

First up is the firm's big hitter, Tahiti, the chip behind AMD's 7900-range. It's generally assumed that towards the centre are the core's Asynchronous Compute Engines, essentially the command processor, surrounded by compute units, with brighter green areas surrounding the top three edges representing the memory controllers and level two cache. Somewhere in the mix, perhaps between the cache and the CUs or embedded between the CU rows are de-coupled ROP units.

Next is Pitcairn, the chip that powers the Radeon HD 7800 series. This GPU has a greater ratio of compute units to cache and memory controllers.



And last is Cape Verde, the Radeon HD 7700 series GPU.
