     GPU market shares Q1 2008

    The unrivaled Jon Peddie, the eponymous research company specialized in financial information, has just published a sample of some of its estimations for graphic market shares for the first quarter. All figures given concern the number of units sold. Given that a GMA 945GM is equivalent to an RV670, we shouldn’t take these numbers too seriously even if they do often represent general market trends. The fifth column shows the difference in the number of units delivered compared to the same quarter a year ago (in parentheses this means a reduction).


    The first conclusion is that Nvidia and Intel to an even greater extent are doing very well. ATI compensates for a 5% reduction in market shares with the fact that unit sales still grew. This figure can explained by an increase that was lower than the overall average market growth. As for SiS, Matrox and VIA , they continued to slide due to a lack of real innovation in this quarter as S3’s Chrome wasn’t available before April. It will be interesting to observe in the coming months if they manage, as little as it may be, to impact the current trend. Intel’s GMAs are found in 46% of PC desktops, Nvidia’s GeForces in 31%, and ATI’s Radeons in only 17%. The sequential increase in this segment was 8.5%.


    On the laptop IGP/GPU market, Intel continued its determined progression which seems to be essentially to Nvidia’s expense as AMD manages to hold its position here. Note that for the quarter notebooks represented 32.6 million units, 31.2% of the market, or 5% less than the previous period.

    Finally, we can see that the market showed a sequential increase of 4% in the first three months of the year which normally are more subdued than the fourth quarter.



     CUDA : 2.0 beta version and a contest

    CUDAA few days ago, Nvidia made available its 2.0 beta version of CUDA, the software interface which enables using GeForce 8/9 (Quadro/Tesla variations) GPUs as massively parallel calculation units. This beta version is available for Linux (as well as for Windows XP and Vista) which is something new as there was no previous support for this OS.

    Nvidia does not specify the innovations of the new version; however, even if the manual does not broach the subject, we can assume that it prepares for the arrival of a new GPU which in addition to a significant performance gain, should add several innovations in terms of calculation such as double (64bit) floating point support.

    Otherwise, Nvidia France is organizing a contest, The CUDA Challenge , for adventurous (European) developers to create an application or plug-in which uses one or several GPUs with CUDA in an interesting way. If you have a GeForce 8/9 and do not know what to do with yourself in the beginning of summer, you have until July 18th to submit your project and potentially win a complete work station.



     Catalyst 3DMark Vantage hotfix driver

    Unsurprisingly, ATI has also released a "Hotfix" for 3DMark Vantage which improves performances while also remedying certain bugs. AMD’s graphic division likes to play on words because the exact name is “3DMark Vantage Catalyst hotfix driver” which apparently sounds better than Cataylst 8.5 beta.

    There is support for all Radeon HD desktop models except 3200 & 3300s (IGPs) with 32-bit and 64-bit Windows Vista. Note that data corruption problems persist with certain Radeon HD 3870s in CrossFire in "High Settings" with Windows Vista 32-bit. All the details are available on AMD’s support site (737-33840: 3DMark Vantage Hotfix).



     ForceWare 175.12 : 3DMark Vantage

    Logo NvidiaNvidia has put online the GeForce Release 175.12 which improves performances in 3DMark Vantage, although neither the release notes nor download page make the slightest allusion to Futuremark’s latest creation. Officially, they improve performances in a number of DirectX 9, DirectX 10 and OpenGL applications and fix various bugs essentially with SLI configurations.

    They are exclusively destined to 32-bit and 64-bit versions of Windows Vista and support the GeForce 6, 7, 8 and 10. You can download it here!



     Cray with Intel for intensive calculation

    Intel and Cray, a specialist of supercalculators, have announced signing a deal for several years. Amongst other things, they plan to work together on different levels on future supercalculators including multi-core processing and interconnection systems. In the next few years, they should develop an entire line of servers and intensive calculation technology.

    Several reasons were given to explain this announcement. It’s notably been heard that Intel’s new partner didn’t appreciate the latest delays of the Opteron Barcelona which had a significant impact on its financial results. Otherwise, the Santa Clara giant’s long term vision, the Larrabee project as well as its rather flexible GPGPU (general purpose GPU) approach is attractive because traditional GPUs, even if they prove to be extremely powerful for certain types of calculation, still suffer from certain technical limitations.
