AMD Radeon HD 7970 vs Nvidia GeForce GTX 680 Driver Comparison

Tbreak has taken launch and latest driver releases for the Radeon HD 7970 and the GeForce GTX 680 and compared how performance has changed.

 

As you can see both the AMD HD 7970 and the NVIDIA GTX 680 perform on par, my guess being that the HD 7970 GHz Edition will outperform the GTX 680 in F1 2012, Battlefield 3 and Civilization V. However, none of these would be meaningful performance bumps as anything beyond 60fps is only for boasting, unless you have a monitor running at 120Hz refresh rate. Even then, though, actual performance benefits are arguable for most competitive games.

AMD's Open Source Radeon HD 8000 Driver

Phoronix discusses AMD's Radeon HD 8000 open source driver they have put out in the wild for Linux.  Yes, the 8000 series is not yet out.

 

AMD's been planning for a second quarter release of the Radeon HD 8000 "Sea Islands" GPUs while the first to arrive hardware will be the HD 8800 "Oland" graphics processors. This hardware that succeeds the Radeon HD 7000 series isn't as radically different as going from the HD 6000 to HD 7000 series, which yielded a better turnaround time with the initial HD 8000 series support.

AMD Catalyst 13.2 Beta Driver Released

AMD has released their 13.2 beta Catalyst driver which not only imporoves performance in Crysis 3 beta, but also with DMC and Crysis 2.  It also addresses the issues raised in the Tech Report article with frame latency in Skyrim, Borderlands 2, and Guild Wars 2.

 

· Improves performance up to 15% in high MSAA cases for the Crysis 3 beta release
o Future updates will be made to AMD Catalyst 13.2 Beta to further improve performance in Crysis 3 for both single GPU and CrossFire configurations
· Significantly improves latency performance in Skyrim, Boderlands 2, and Guild Wars 2
· Improves single GPU performance up to 50% for DmC Devil May Cry
· Improves CrossFire performance up to 10% for Crysis 2
· Resolves Texture flickering seen in DirectX9.0c applications.

AMD Catalyst 13.1 Drivers Released

AMD has released their 13.2 Catalyst drivers today.  They include all of the improvements from the 12.11 beta drivers.

 

AMD Catalyst 13.1 features a newly designed 3D application settings page, allow users to more easily adjust and control their 3D settings on a per application basis.

Catalyst 13.2 Beta Driver Update Helps Radeon Frame Times

Tech Report has tested AMD's Catalyst 13.2 beta with a Radeon HD 7950 and it has shown to improve stuttering or frame draw times.

 

We asked Mr. Dodd whether the changes included in this beta driver would impact performance generally in DirectX 9 applications or only in the three DX9-based games we tested. We also inquired about whether the previously mentioned buffer size tweak for Borderlands 2 was included. Here's his answer:

Basically the fix was different per application (for the DX9 applications) – each fix involved tweaking various driver parameters. In the case of Borderlands 2, yes it did involve tweaking the buffer size.

So what we have in Cat 13.2 is a series of targeted tweaks that appear to work quite well for the games in question. However, Dodd says additional improvements are coming down the pike, including a rewrite of the software memory manager for GPUs based on the Graphics Core Next architecture that should bring a more general improvement:

The driver does not yet contain the new video memory manager. Our intention is release a new driver in a few weeks, which does include the new Video memory manager, which will help resolve latency issues for DX11/DX10 applications.
