Last week, NVIDIA launched its new GeForce GTX 275 video card to compete against the ATI Radeon HD 4890. The launch was originally targeted for April 14, and our sources indicated that there were only around 5,000 units available on launch day.
However, one of our sources emailed us some links last night to e-tailers Newegg and Mwave to prove North American availability of the GeForce GTX 275.
Another email DailyTech received claimed that NVIDIA has "shipped 10s of thousands of chips to our board partners. Our board partners are in mass production and they have already started to make these available through retail and e-tail channels."
"Timing of course, depends on the region. But clearly, the floodgates are open," the source elaborated.
Based on the GT200 architecture, the GeForce GTX 275 features 240 processor cores operating at 1404 MHz, 80 texture processing units, a 448-bit memory interface, and an 896 MB frame buffer. NVIDIA is positioning it between the GeForce GTX 260 and the GeForce GTX 285 in price and performance. Benchmarks have shown that it exhibits slightly better performance over the Radeon 4890 in most gaming applications.
Pricing on the other hand, favors the Radeon 4890. Using mail-in rebates, the graphics division of AMD has already lowered the price to under $230. Further price cuts are probably coming, as the RV790 chip that the Radeon 4890 uses is much smaller and cheaper for AMD to manufacture. The G200b chip that the GTX 275 uses has 1.4 billion transistors, while the RV790 only has 959 million. Both are manufactured on a 55nm process.
