NVIDIA GTX 275 vs ATI HD 4890
NVIDIA and AMD launched new graphic card on the same day as the completion heats up. As the names indicate the two cards are not aimed at the high-end performance but at a little lower level. The truth of the matter is that neither one of these cards is particularly new, they are both a balance of processors, memory, and clock speeds at a new price point.
NVIDIA GeForce GTX 275 graphics card is basically half of a GeForce GTX 295 and it has been overclocked for even better performance than the GeForce GTX 260. The Radeon HD 4890 is the designated successor of the HD 4870 and now AMD’s fastest single GPU graphics card.
AMD’s graphics department Ati did some fine tuning and delivered a chip with a higher frequency range, codename RV790. For now the RV790 is used on the HD 4890 only and is clocked to 850 MHz. AMD claims that these graphics cards can easily reach just shy of 1GHz on the core and 1050MHz+ on the memory without touching the voltages.
The GeForce GTX 275 is based on the GT200 architecture, featuring 240 shader processors operating at 1404MHz. In price and performance, the card sits between the GeForce GTX 260 core 216 and the GeForce GTX 285. The GeForce GTX 275 also differs from the GeForce GTX 285 as it has two fewer memory ICs, so it has a total frame buffer size of 896MB instead of the 1GB.
