AMD Radeon HD 7950 targets more common gamers
AMD has hoped to corner the more widely accessible range of high-end video cards Tuesday by unveiling the Radeon HD 7950. It trims back slightly from the range-leading 7970 with 1,792 visual processing cores instead of 2,048, 112 texture units instead of 128, and both 800MHz core and 1.25GHz memory clock speeds versus the 925MHz and 1.38GHz of its counterpart. The chipset is still powerful enough to handle 4K video and carries the 384-bit memory bus and 3GB of video RAM.
AMD Radeon HD 6850 and 6870 official
AMD tonight kicked off the launch of a new graphics core generation by launching the Radeon HD 6850 and 6870. The designs are roughly on par with the performance of the outgoing 5850 but, through a new architecture, are considerably cheaper at $179 (6850) and $239 (6870) while still being more power efficient, particularly at idle. The chip designer claims a performance edge of as much as 30 percent over the GeForce GTX 460; the move has already forced NVIDIA to drop the GTX 460's average price to $199 to compete.
Radeon HD 5000 series gets budget chipset
AMD this morning launched its least expensive video chipset capable of DirectX 11 (and OpenGL 3.2) graphics. The ATI Radeon HD 5450 has all the same visual effects as the 5600 and 5800 lines but is trimmed down to 80 stream processors, 8 texture units and a 650MHz engine clock speed. Besides keeping the price low, the design allows for extremely quiet cards: it can either use a low-speed fan in a single slot or a completely fanless design in a slightly larger space.
GeForce GT 240 updates NV's budget GPUs
NVIDIA in a low-key move today launched the GeForce GT 240. The chipset brings performance from the mid-level to sub-$100 cards and uses the newer 40 nanometer manufacturing process to make itself a reasonable fit in budget PCs: its low energy use both helps it occupy only one slot and to run entirely off the power of the PCI Express bus instead of needing a separate power connector.
ATI Radeon HD 4890 1GHz
In a rare move of its own, AMD today launched a factory-overclocked version of its ATI Radeon HD 4890 graphics chipset. The move takes the 850MHz core clock speed of the standard edition and boosts it to 1GHz, rendering the new version the first graphics processor of any kind to reach the milestone. AMD claims that the simple shift boosts the peak computing power from 1.36 teraflops to 1.6 and is theoretically faster than NVIDIA's GeForce GTX 285.
XFX, AMD announce team-up
PINE announced on Tuesday that its graphics division, XFX, is partnering with AMD to offer ATI Radeon-powered graphics cards, including the company's HD 4000-series GPUs. Up until now, XFX only offered NVIDIA-based graphics cards, but it's believed NVIDIA's recent GPU quality issues and the price cuts on its GTX line of cards are what's causing many graphics card makers to turn elsewhere to restore their margins.
NVIDIA GF 9400 for Desktop
Following last week's introduction of the GeForce 9400M for MacBooks and other notebooks, NVIDIA has also introduced the GeForce 9300 and 9400 for desktop systems. The two not only support the full range of Celeron, Pentium and Core 2 desktop processors but carry roughly the same 16-core graphics processing as the 9400M and thus have much faster 3D performance than Intel's GMA 4500.
XFX, EVGA leave Nvidia
After a recent bout of bad press – alleged mass product defects, competitive price cuts, and legal problems – two of Nvidia's largest partners have supposedly jumped ship to pursue alternate ventures with an unnamed company. The news follows the loss of Gainward, a company now fabricating ATI-based boards. While details of the supposed deal are scarce, it is known that the two companies, XFX and EVGA, are not defecting to rival GPU manufacturer ATI.
