Intel shelves Larrabee gpu project
Intel has shelved plans to continue development of Larrabee graphics processor. Intel spokesperson Nick Knupffer said that Larrabee silicon and software development are behind where Intel hoped to be and as a result the first Larrabee product will not be launched as a standalone graphics product, rather it will be used as a software development platform for internal and external use. At SC'09, Intel demonstrated Larrabee computational power which peaked at over 1 TFLOP. More »

Nvidia GT300
Nvidia presented the main competitor to Amd Radeon HD 5800 series, the GT300 chip (codenamed Fermi), the first DX 11 chip from Nvidia. According to information presented on GPU Technology Conference the GT300 will have 3 billion transistors, 512 shader processors (referred as CUDA cores), 32 cores per core cluster, 384-bit memory interface and maximum 6GB of GDDR5 memory.

ATI Radeon HD 5800 series
AMD today launched the ATI Radeon HD 5800 series graphics cards, the world’s first to fully support Microsoft DirectX 11 included in Microsoft Windows 7 operating system. AMD will initially release two cards: the ATI Radeon HD 5870 and the ATI Radeon HD 5850, each with 1GB GDDR5 memory. The 5850, which is a cut down version of the 5870, is clocked at 725Mhz for the core and 1Ghz for the memory, giving it a maximum compute performance of 2.09 TFLOPS. More »
AMD R800, RV870 and RV840 Expected Late 2009
According to Hardware-Infos AMD is set to release a lineup of DirectX11 compliant 40nm GPUs within 2009, targeting NVIDIA’s upcoming G300. Besides RV870, there will be R800 that consists of two RV870 chips, RV840 for mainstream market and RV810 for entry level market. Probably named as Radeon HD 5870, RV870 will be powered by 1200 stream processors, GDDR5 memory and bandwidth of 143 GB/s. RV840 and RV810 GPUs specifications are still unknown. More »
GT300 to feature 512-bit interface
Over the past six months, we heard many rumors about the upcoming nVidia GT300 GPU. The last information surfaced on the web reveals that GT300 might feature a 512bit wide GDDR5 memory interface. If this is true, this would mean that nVidia has a playing field of eight 32bit memory controllers connecting to multiple 32 core clusters for a total of 512 cores. If the GT300 chip ends up connected to quad data rate memory at 1000MHz we'll have a memory bandwidth of 256GB/s per single GPU. More »

AMD Sabine Platform Will Support DirectX 11
As reported by Expreview, AMD is working on a notebook platform with DirectX 11 compliant integrated GPU. The integrated GPU will be part of the APU (Accelerated Processing Unit), a new design approach where the CPU package holds both the CPU and the northbridge in a multichip module. The AMD APU, codenamed Llano, will be part of the Sabine mobile platform together with the SB9xxM series southbridge. More »
RV790: 55 nm Manufacturing Process
A lot has been said about ATI's RV790. Clues about the new gpu surfaced in the last November when was clear that AMD was working on a successor to the RV770. A german website, Hardware-Infos, reports that RV790 will be built on the newer improved 55 nm manufacturing process. The new gpu may get a little help from its superior silicon fabrication, foundry partner codename is 55GT, which makes it more expensive to manufacture. According to the source there are two RV790 engineering samples: a base model and an overclocked model. More »
