The official covers of two 3D graphics cards, the ATI 1GB Radeon HD 4890 and the Nvidia 896MB GeForce GTX 275, came off Thursday morning.
At $250 for the baseline cards (overclocked models will be available for each for $10 or so more), these cards establish a new midrange battleground, filling the gap between the $150 and $300 price points we covered earlier this year.
Each of these cards, respectively from Advanced Micro Devices and Nvidia, has a two-slot PCI Express design that requires two six-pin cable connections to your PC's internal power supply. They also support each vendor's respective multicard technology, Crossfire for ATI, and SLI for Nvidia.
The Radeon HD 4890 doesn't introduce much in the way of new features, though it has a clock speed bump over its Radeon HD 4870 cards released last year. The core clock has gone from 750MHz on the 4870 to 850MHz on the 4890, and the memory from 900MHz to 950MHz.
AMD's ATI made a few other tweaks to memory bandwidth and fill rates, but for the most part, the two cards are very similar. The Radeon HD 4890 is available now at various online retailers, and prices so far reflect ATI's suggested $249 baseline.
Nvidia's new GeForce GTX 275 is slated to become available for purchase on April 14. And while we don't imagine that Nvidia could simply make a new 3D card appear overnight (nor do we necessarily know which vendor actually started taping out its new card first), we find it interesting that mere days after ATI called us for a briefing on the Radeon HD 4890, Nvidia got in touch regarding its own new product. … Read more
