      AMD Posts Catalyst 12.1 Drivers, Catalyst 12.2 Preview

      Guest

      AMD has posted its first Catalyst driver package of the new year, Catalyst version 12.1, the feature set of which hasn't changed much since the preview release - the banner feature is still custom [PRBREAK][/PRBREAK]application profiles, which allow users to create custom 3D and CrossFire setting for individual games. This has long been a feature offered by NVIDIA's driver packages, and it's nice to see AMD implementing it. AMD notes that users of the Catalyst 12.1 preview package should restore the Catalyst Control Center's default settings after upgrading to prevent compatibility issues.
      The 12.1 drivers also enable 3D display support for CrossFireX setups, and a "Stereo 3D mode" over HDMI 1.4a connections which supports 1080p at 30Hz on displays that can take advantage of it. New video color and quality adjustment panels offer no new features but aim to simplify adjustment of those settings. A handful of game and bug fixes for Windows 7 and Vista users round out the release notes.
      The Catalyst 12.2 preview, available here, focuses primarily on Eyefinity 2.1 improvements. These include a "larger" selection of resolutions are available, the drivers will automatically switch between different display configurations as monitors are plugged in and unplugged, the HydraVision software now allows the Windows taskbar to be moved and resized, and the driver also offers "increased support" for Display Groups, including groups of up to five monitors. Additionally, the 12.2 driver addresses many of the "known issues" with games present in the 12.1 drivers.
      Interestingly, neither driver offers support for the newly-released Radeon HD 7970 cards

      Raspberry Pi Computer Costs $25, Plays HD Video

      Guest

      The Raspberry Pi Foundation is developing a very low cost Linux computer based on the ARM11 CPU. The graphics chip is made by Broadcom, and the company has claimed that the chip features[PRBREAK][/PRBREAK] double the graphical performance of the iPhone 4S. If the claims are true, then the graphics chip will be able to vastly outperform the 700MHz ARM11. In addition to claims that it outperforms the iPhone 4S, the executive director at Broadcom, Eben Upton, also claims that its chip outperforms the Tegra 2 from NVIDIA. Upton was upfront when he made the claims, stating that "I was on the team that designed the graphics core, so I'm a little biased here, but I genuinely believe we have the best mobile GPU team in the world at Broadcom in Cambridge." It will be interesting to see some actual comparison numbers when the Raspberry Pi boards become available for sale.
      There have been some efforts made to back up the claims made by Upton, with a demonstration of the open source HTPC front-end XBMC running on a Raspberry Pi board at the SCALE 10x conference. There will be two versions available, the Model A and Model B, which will cost $25 and $35, respectively. As someone that has experience with programming for a variety of embedded systems, I will be watching the Raspberry Pi with eager anticipation.

      GPU-Z 0.5.8 Released

      Guest

      TechPowerUp today released the latest version of GPU-Z, our popular video subsystem information and diagnostic utility that provides you with accurate information about the graphics hardware installed, and lets you monitor their[PRBREAK][/PRBREAK] clock speeds, fan speeds, voltages, VRAM consumption, etc., in real-time. Version 0.5.8 introduces two new features. The first one is a render test that applies sufficient load (not stress) on the GPU to pull it out of PCI-Express link-state power-management, to ensure the Bus information is accurate. If you find the PCI-Express bus link speed or PCIe version displayed incorrectly, simply click on the "?" button next to the field to launch the load test.
      The next new feature is ASIC quality, designed for NVIDIA Fermi (GF10x and GF11x GPUs) and AMD Southern Islands (HD 7800 series and above), aimed at advanced users, hardware manufacturers, and the likes. We've found the ways in which AMD and NVIDIA segregate their freshly-made GPU ASICs based on the electrical leakages the chips produce (to increase yield by allotting them in different SKUs and performance bins), and we've found ways in which ASIC quality can be quantified and displayed. Find this feature in the context menu of GPU-Z. We're working on implementing this feature on older AMD Radeon GPUs.
      DOWNLOAD: TechPowerUp GPU-Z 0.5.8
      The full change-log follows.
      Added explanation about PCI-Express power savings and 3D render test to accurately measure bus config under load
      Added function to display ASIC quality for Fermi and Southern Islands. (Located in the GPU-Z system menu)
      Fixed crash on older ATI cards
      Added voltage monitoring for HD 7970
      Improved real-time clock monitoring for HD 7970
      Fixed OpenCL detection for AMD Antilles, Whistler, Seymour, Blackcomb
      Improved default clock reading for AMD HD 7970 and Fusion
      Added support for AMD FirePro V7900, HD 6930, HD 7690M, HD 6410D
      Fixed Intel Sandy Bridge IGP to be DirectX 10.1, 32 nm
      Added support for NVIDIA Tesla C2075, GeForce GT 630M

      AMD A6 3500 APU review

      Guest

      AMD's consumer targeted APUs have been released with good success. The biggest success is that they found their way into notebooks, but even in the desktop segment they work out quite well. The APU yes, silicon that holds both [PRBREAK][/PRBREAK]an GPU and CPU harbored inside that APU -- Fusion.
      Now before we start of this article let's be clear here, we are talking about entry level to mid-range targeted processors (well -- APUs). So we are looking at reasonable up-to okay CPU performance versus a rather kick ass integrated GPU, and all that for very interesting prices.
      We look at entry level hardware, for a great deal you get some processor power and actually quite some decent GPU power all harbored inside that processor. We'll go even weirder though, as today we'll be testing a triple core APU, yes that is an APU with three physical CPU cores activated, instead of the four you expected.
      This three CPU cores product was actually announced back in August already but now finally seems to be available in good volume in the stores, at the nice price of only 70 EUR (here in the Netherlands).
      The AMD A6-3500 APU is rated at 65W power consumption and is running at 2.1 GHz, AMD's Turbo Core is supported so you can see clocks of up to 2.4GHz depending on the workload. These Socket FM1 APUs have a 3MB L2 cache and still pack 320 Radeon (shader) cores with that embedded GPU running at 443 MHz with what AMD calls a Radeon HD 6530.
      Though not the cool 400 shader cores the A8 series has, it remains a leap in performance for integrated graphics alright.
