Phoronix: Mesa R500 Texture Semaphore Improvements

Tom Stellard, the former Google Summer of Code student who worked on ATI R300 GLSL compiler improvements and a new register allocator, has been looking into the area of Radeon OpenCL support while now being employed by AMD. However, Tom is working on other open-source Radeon work too. Recently he made improvements to the R300g driver's instruction scheduler to make better use of the texture semaphore.

I was waiting for this benchmark. The results are great!

Texture semaphore is something specific to R500 or it could be used too in R600+ GPUs?

You can find X1950XTXs for $40 these days, they where the fastest GPUs in the R500 compatible family

Here it is against the HD4890, the best supported high performance card in the R600 line http://www.gpureview.com/show_cards....=442&card2=608

I'd have pitted it against the X1800, but Michael, in his usual half assed ways neglected to list which of the 4 versions of the X1800 he actually has both here and on OpenBenchmarking, thus I have to make a quarter assed bitch post.

So which is it Michael, the lowly X1800GTO or the full enchrido X1800XT/Crossfire? Either way it's still easily trounced by the X1950XTX, which should be good enough for anything not based on Unigine if the drivers continue to improve.

Yeah, I bought one too


EDIT: where is my sign? O_O

If you read the article, I clearly mention it.... (hint: bottom of first page right below the table.)

Additionally, the list is entirely auto-generated and it's the ATI video BIOS that only exposes the 'X1800' portion and not the complete string.

No, not at all. I still could have edited it and as the admin I have full edit rights to any post at all, but I simply felt like replying to save time.

It's part of the r5xx fragment shader ISA so it's specific to r5xx hardware.

Ok thanks.
