AMD Cayman info (or rumor)

[zerazax]

Hmm... haven't seen that.. mind linking me?


VLIW5 stands for "Very Long Instruction Word" 5; VLIW standing for the architecture basis, 5 for the number of execution units.
Each shader 'unit' is composed of 5 execution units, 4 of them being 'simple', with the 5th being able to handle all functions, including transcendental functions.
This is one (of many) reasons that AMD's u-arch's generally have more shaders than nvidia, yet has comparable performance; unless the developer specifically codes for this unique computing style, a game will only use some of the execution units. This is also one reason why the theoretical computation power for AMD's u-arch's are far greater than what is actually achieved in actual applications, because AMD's figures assume that all execution units are utilized.

I don't have the link, but Gipsel posted about it underneath and was the one who posted about it in the R9xx speculation thread on b3d

so without starting a flamewar...

...is this going to be the Dogs bollox?

As I posted here at the beginning of this thread: http://www.xtremesystems.org/forums/...55&postcount=2

Reviews on Barts have given hints that Cayman is a superset of Barts, meaning it will have more features than Barts has, and that Cayman is focused on high end GPU performance. Given that this is a break from the old AMD strategy, I bet it's a big deal

I seriously think that Barts was released first as a simple teaser for what's to come with Cayman and Antilles. If Cayman is a beast, Antilles will be Chuck Norris.
