Adapting to Parallelism: Catalyst 5.12 More Dual Core Friendly?

Day of Defeat: Source Performance
We found Day of Defeat: Source to be the benchmark that sees the most consistent benefit from the 5.12 driver and dual core. As is plain from the graphs, performance on the dual core system under the 5.12 driver is on top in every test.
This could indicate that Day of Defeat is CPU limited all around and so gets a good boost from the more efficient use of resources. Of course, even under the 5.12 driver the game is still very CPU limited at low resolutions.

How much RAM did the test system have?Furen - Sunday, December 4, 2005 - link
Since integrated graphics cards are the ones that (currently) lack things like vertex shaders, they probably will get a much more "dramatic" performance increase from dual-core drivers.Cybercat - Sunday, December 4, 2005 - link
amazing improvements! At 800x600...Pannenkoek - Sunday, December 4, 2005 - link
Indeed, I guess this article has only been posted because someone at Anandtech has worked on it, and didn't want to have wasted his time entirely for some beta drivers no one cares about.Cygni - Sunday, December 4, 2005 - link
Ya, im sure all those people with Dual Core rigs, and all the people that will have Dual Core rigs by the end of this year (probably everybody on this board), doesnt care about Dual Core driver improvements.In other news, i hope that post was a joke...

This is a _beta_ driver, not a released driver. Anandtech could have waited for the actual release. Now we won't be seeing any article on the real thing when it will come out is my guess.Yeah, I'm sure all those people with bleeding edge dual core processors and newest generation ATi cards will rejoice at their 5 extra frames per second at the lowest humanly tolarable screen resolution in this age.
Besides, it can only be pathetic if they actually get real performance improvements. On higher resolutions it would only show how lousy their drivers would be if they use that much CPU power to make an impact in benchmarks if the driver is off-loaded to another core. And on lower resolutions they apparently stall their rendering pipeline with current drivers. Thumbs up.

Are you seriously saying that it would be better to not know this? I was also under the impression that they were going to post a followup with more tests.-- Andyvan

I never said it would be better to not know this, whatever this may be. The article states explicitely that there'll be a follow up, I was a bit too cynic perhaps. ;-)The point is, there's a lot of fluff about some beta driver which "takes advantage of dual core". Earthshattering. It's the least any graphic card driver developer could do. And I welcome any comprehensive tests and article by Anandtech on real products. I just don't see any point in this article, especially not in the light of an upcoming "complete" article. (I see one: self-advertisement). Good effort by the Anandtech crowd, but it annoys me after all the other prerelease & beta & exclusive vapourware reviews.

Keep in mind that ATI's drivers seldom change once they hit beta. Once they're in beta, ATI is usually done with any coding and internal testing, and they're simply handing these drivers out to their partners for testing to see if in the unlikely event a problem crops up. So I certainly wouldn't consider these drivers vaporware, since they will be in everyones hands in another week or so.As for why we did this article instead of waiting for the complete article, we felt it was more important for you to be able to see what ATI's dual-core changes are capable of now on the best of hardware, rather than wait longer for a full-comparison article. With the need to swap CPUs on top of everything else, it's going to take us some time to finish the full article. We can certainly wait until we have every last benchmark done, but we'd rather show what we have now and get feedback from you guys, rather than keep you in the dark any longer.=)

Don't mind him Ryan. Some people won't shop for a Ferrari until they can afford one.
