    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.

    Intel Atom D2700 - Cedar Trail with less-than-anticipated capabilities

    With the official launch of Cedar Trail's desktop variants D2700 and D2500 just a few days ago, more and more details about the (ultra) mobile processor based on Intels Atom mircoarchitecture are starting to appear.

    While you can read about the chip's 1.86 to 2.13 GHz frequency, their 42 - 52 Dollar price, their 32nm manufacturing, their NM10 chipset and similar basics elsewhere, I am going to concentrate on some peculiar facts that either just surfaced or were confirmed through Intels data sheet for Intel's D2000 and N2000 series of Atom processors: The missing DirectX 10.1 support, (almost) no power management for the IGP or the limited video decoding support.

    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.

    Nvidia Geforce 405 OEM - a non-Fermi card

    Nvidia has a long history of selling older technology under a new and shiny name to make it more compelling to the less informed customer. The most recent example is the Geforce 405, a supposedly OEM-only model, that is using apparently a GT218-like chip and is not even capable of the same API-level features that Nvidia hypes about it's namesakes of the Geforce 400 series, namely Tessellation, Compute Shader 5.0 and the whole rest of DirectX 11 exclusive technology.

    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.]

    After having read through this article by german it-site golem.de I tried to have a look at the linked US-patent D642,172 from July 26th 2011, describing a claim for „The ornamental design for an electronic device, as shown and described.” Naturally, I became interested and wanted to have a look at the great piece of art worthy of being protected in such a manner. But alas, I failed! ...

    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.
