We've learned a lot in recent weeks about the GeForce GTX 460, which should be Nvidia's cheapest DirectX 10 GPU to date. Now, the rumor mill is starting to spill some dirt about other, even cheaper Fermi derivatives.
According to the folks at Coolaler, Nvidia has another two GPUs in the oven: the GF106 and the GF108. The former will reportedly power GeForce GTS 450 and 455 graphics cards scheduled to appear in August with $129-179 price tags. Specifications are "unclear" for now, but if I were a betting man, I'd say Nvidia will try to give AMD's Radeon HD 5700-series cards a run for their money.
Next up: the GF108, which will follow in September. Coolaler got hold of even fewer details about that part, but it talks of sub-$100 pricing and direct competition with the Radeon HD 5600 and 5500 series.
In an interesting addendum, the site claims Nvidia has placed huge orders with TSMC in preparation for these launches, and supply of AMD graphics chips may run tight as a result. Word is that TSMC gives priority to "large customers" like Nvidia when deciding whose chips to manufacture. We wouldn't necessarily discount that rumor, especially since Taiwanese sites like this one often have good connections. However, judging by recent figures from Jon Peddie Research, Nvidia's share of the GPU market is only a few points bigger than AMD's—maybe not enough for TSMC to give the underdog the cold shoulder.
