    AMD APP SDK 2.6 component versioning

    Just a quickie this time. AMDs developer page has been updated as of now with the checksums of AMD APP SDK 2.6. The files linked there as of this writing are still 2.5, but if you alter the link to point to 2.6 instead of the linked SDK, you get the brand new APP SDK 2.6. But please try and visit their site first - they should have updated it any minute now. In a blog-entry from a couple of days ago, AMDs Mark Ireton apart from revealing today's launch date for the 2.6 SDK, already outlined some of the changes, AMD APP 2.6 will bring. Most notably, Open CL 1.2 will be on the support list for 2012 where AMD is commited to fully support the most important open GPU-Compute standard on both CPUs and GPUs. The APP SDK 2.6 is to include previews on some of OpenCL 1.2's core features according to AMD.

    AMD Catalyst 11.11 WHQL Version Numbers

    After last month's very late release of Catalyst 11.10, the November issue of AMDs Radeon graphics drivers, Catalyst 11.11 WHQL is available for download already. AMD also issued the first Catalyst Application Profile, short CAP, for 11.11 release, which adds tweaks for the Battlefield 3 profile in Crossfire multi-GPU configurations, improves Crossfire performance for Global Ops: Commando Lybia and disables Crossfire - probably there have been issues - for Driver San Francisco.

    AMD Catalyst 11.10 WHQL is out

    Catalyst 11.10 WHQL is finally available and it is the first official driver release for Radeon graphics cards after the final version of this years' most anticipated game, Battlefield 3, came out. Strangely enough, Battlefield 3 is nowhere mentioned throughout the release notes, which you can review for yourself here or use the attached version below (Updated, see below!). AMDs Andrew Dodd, going by the name of CatalystCreator in the microblogging service twitter, recommends to use Catalyst 11.9 CAP4 after installing Catalyst 11.10 WHQL. Catalyst Application Profiles or CAP for short, are linked below as well. He goes on to say, that Catalyst 11.10 WHQL contains the same fixes as are present in the earlier Catalyst 11.10 Preview v3 drivers.

    AMD Catalyst 11.9 WHQL

    AMDs Catalyst driver 11.9 WHQL is out and actually preceding it, AMDs Catalyst 11.10 Preview was made available for the Battlefield 3 (Open) Beta. While the former is mostly a welcomed bugfixing driver, the latter brings some changes with it - not counting the performance improvements for the Battlefield 3 Open Beta currently underway.

    The Catalyst 11.9 WHQL driver adds support for some DisplayPort panels in AMDs Stereo API HD3D and apart from that is not very spectacular. It installed without a hitch on my freshly set-up Phenom II system coming from the 11.8 WHQL and features a nice list of improvements with regard to functionality and bugfixes rather than performance improvements. Those seem to be reserverd for the 11.10 driver as the preview version made available for the Battlefield 3 Beta (did I mention it already?) brings some of them along with a few new GUI elements, namely in the Overdrive, CrossfireX and Information Center sections. But first things first.

    AMD Catalyst 11.8 WHQL version numbers

    AMDs has put up it's Catalyst drivers 11.8 WHQL up for download. This time, they feature some nice performance improvements for DirectX 11 titles like Crysis 2 (up to 10 percent improved framerate) and F.E.A.R. 3 (up to 8 percent higher fps) as well as being up to 30% faster when performing AMDs Morphological Antialiasing.[Update: CAP3 provides many more game profiles, including crossfire improvements for Max Payne 3 - obviously nearing it's release.]

    AMD Catalyst 11.7 WHQL Driver Suite

    Catalyst Drivers 11.7 WHQL and 11.8 Preview have been readied for download and AMD has moved their APP-SDK for accelerating OpenCL applications to version 2.5, now finally supporting Double Precision/Doubles/FP64/watchamacallit via cl_khr_fp64. The caveat though: It's only included for Cypress-based GPUs, not Cayman and not older chips capable of 64 bit precise calculations. According to AMD, APP 2.5 now also leverages AVX, Advanced Vector Extensions on CPUs supporting it, namely Intel's Sandy Bridge and AMD's upcoming Bulldozer. The first CAP release for 11.7 also includes optimizations for the alpha-version of Battlefield 3. Additionally, AMD has posted a preview driver for Catalyst 11.8 which promises speed improvements in DirectX 11 mode for Crysis 2 and Fear 3, 30 percent faster MLAA and HD3D-support for DP monitors.

    Nvidia Logo

    Largely unnoticed, Nvidia has added support for OpenCL 1.1 to it's publicly available Geforce driver 280.19 - only months, 9 to be precise, after AMD has outfitted their Catalyst driver suite with that OpenCL revision in 10.10 release and only weeks after Open CL 1.1 has been officially introduced. To be fair though, Nvidia has provided registered developers with earlier driver releases featuring OpenCL 1.1 for quite some time now. But it seems as if all the beta testing did not reveal the performance issues surfaced with the first open installment of Release 280 Geforce drivers. At least in the OpenCL space, performance has drastically been reduced for some applications. Luxmark 1.0 for example sees my trusty Geforce GTX 480 now at 62 to 65 percent of it's former potential, ...

    Chipmaker AMD has a concise portfolio of CPUs, GPUs and as a combination of both in one silicon die APUs.

    AMD has put it's Catalyst driver suite 11.6 WHQL on its way a few days ago. With the official integration of AMD Steady Video, which I've reported on earlier already, the company is starting to pick some more or less low-hanging fruits from it's Fusion-platform. Steady Video leverages the processing power of the GPU in order to remove shakiness from cheap internet video aka Youtube - more on this further down the page. This 11.6 Catalyst WHQL driver is intended for all HD-Radeons capable of DirectX 10, 10.1 or 11 as well as Fusion-APUs from the Brazos-Series (C-50, E-300, E-450) and the recently introduced Llano quadcore-APUs (A4,- A6- and A6-series).

    [Update July, 9th 2011: AMD has rolled out two hotfixes for Catalyst 11.6 Radeon drivers and has made available an early preview of Catalyst 11.7 on it's Developer's website. The hotfixes add support for AMD's A-Series APUs (Hotfix 11.6a) and resolve bluescreens (BSOD) when a Radeon graphics card is connected via HDMI or Display Port instead of DVI.

    AMD Catalyst 11.5 supports all HD 6000 cards now

    AMD's driver department seems to long for a prolonged vacation this year, so they bolted down the new Catalyst Driver Suite 11.5 WHQL in record time in the first third of the month already and uploaded them on their servers. The announcement on their download site should be live any minute now. According to packaging and Catalyst Control Center timestamp, this WHQL-Driver for all HD-Radeons (yay! finally) capable of DirectX 10, 10.1 or 11, was finalized only two weeks after the official Mjölnir-Release. Unfortunately, this release can not compete in astonishing number in terms of performance increases with Mjölnir also, but that's not necessarily a bad thing. AMD's software engineers seem to have concentrated on fixing bugs and adding a new and improved control panel for the video section - I have a side-by-side comparison below (it's almost like I've had a hunch…). ...
