ATI Radeon HD 4800 X2 GPUs

AMD on Tuesday debuted its ATI Radeon HD 4800 X2 series of graphics chips, including its flagship ATI Radeon HD 4870 X2 dual-CPU graphics cards; the combination, it claims, delivers 2.4 teraFLOPS of processing power and its value-oriented sibling ATI Radeon HD 4850 X2. The new cards combine two ATI Radeon HD 4800 series GPUs using a faster PCIe 2.0-based interconnect and 2GB of frame buffer memory. Launched in New York City this week, the GPUs are based on the advanced 55nm design and offer DirectX 10.1 support for advanced gaming and ATI CrossFireX for maximum performance: ATI says that the efficient use of all four GPUs in a dual ATI Radeon HD 4870 X2 CrossFireX configuration will bring more than three times the performance (using 3DMark Vantage v1.01 benchmarks) of a single ATI Radeon HD 4870 card in many games.

Nvidia cuts Q2 earnings

Nvidia says that a heat problem in with one of its mobile chips will hurt its earnings for the second quarter, sending its shares tumbling down almost 25 percent to below $14 in after-hours trading. According to the Wall Street Journal, Nvidia said that the overheating problem -- which appears to be focused on older chips for notebook computers -- caused higher-than-normal failure rates in certain GPU models as well as related chip sets; the company's said that it could see a revenue shortfall of nearly 24 percent in the second quarter (ending July 27th), but also cited problems such as general market conditions, price cuts to match rival AMD, and delayed product ramps. In June, the company debuted its Nvidia GeForce 9M series, which it said was built on a new, multi-core graphics engine that is up to 40 percent faster than its earlier 8M chipsets; the GeForce 9M series chips were set to appear this summer, and while a few manufacturers had already begun shipping designs with the newer GPUs, the company used most of the quarter to push out its older chips.

NVIDIA plans GeForce GTX for June 18th with PhysX?

05/22, 1:10am

NVIDIA GeForce GTX coming?

NVIDIA plans on refreshing its GPU line-up next month with two new graphics card that will feature its next-generation CUDA-enabled graphics core, codenamed D10U. The company is expected to deliver both the GeForce GTX 260 (D10U-20) and GeForce GTX 280 (D10U-30) on June 18th as part of its summer refresh, according to DailyTech. The report claims that the GTX 260 will be a "significantly" scaled down version of the GTX 280, which will enable all 240 unified stream processors designed into the processor. These second-generation unified shaders perform 50 percent better than the shaders than its previous-generation offering, the company claims in its documentation; however, the new NVIDIA cards will only support GDDR3 memory and DirectX 10, while AMD focuses on faster GDDR5-based cards due early this summer.
