Hello All,

 

Just wanted to put this out there. The website pcper.com is posting Mantle benchmarks that show AMD in a bad light. The Crossfire performance is worse according to his benchmarks compared to a single card FPS.

His test setup said he was using 14.2 Beta driver. When I called him on that as a possible cause of the unexpected crossfire benchmarks in the comments section he replied he was using the 14.4 beta. 

As you may already know 14.4 is not yet released. His review never mentions anything about him using a pre-release driver. 

After I called him on it he changed the testing methodology page to reflect 14.4

 

 

I'm calling BS on this. Even if he was using the 14.4 driver in a pre-release form there is no way the NDA he is bound to would allow him to post benchmarks.

Check the comments section yourself and you will see the exchange

It doesn't really matter. Mantle is about consoles. Performance on consoles is calculated during developement, and hardware is the same in all of them.

Mantle for PC only exists to shut the mouth of a few geeks. The same marketing strategy we saw with the so-fantastic-but-never-ever-used DX 10.1 back in the days of the 4k series. It will never become mainstream for the same reason nvidia physix didn't become mainstream.

...also, the main purpose for Mantle is to allow mid-level or below computers with borderline graphics and processors to be able to play a game that has been optimized for Mantle. High end, including crossfire, computers will see little or no improvement. I don't believe that pc gamers when choosing their 'next' computer will buy marginal GPU/Processors because of Mantle. DX10.1 is a perfect example.

yes, i remember that he wrote about 14.2.... and then changed

but why?

BTW i think that multigpu in Mantle is more application side...

wait for the April drivers and will see...at the moment i'm not running crossfire anymore, just a single R9 290, want to see a more clear phase about multigpu performance (and even better support) to come back to crossfire again... the problem is that henceforth the Mantle multigpu optimizations will be done by game developers, is it better or worse? how many devs will optimize from scratch the multigpu Mantle code? whatever game (Dx or Mantle) will be supported by multigpu... or the same old story?

You would think that a game developer would want to optimize his game for Mantle...mainly so they could lower the minimum specs to play it...at a resonable frame rate. But now we have DX12 coming into the picture that touts similar benefits. The question is, will it support any OS besides Windows 8?

The site is just using the ridiculous and useless concept of "runt" frames.  The results are worthless.
