Rumour: Four more Fermi chips this summer

Although Nvidia only just officially unveiled the GeForce GTX 460 at Computex, the word is that the company is gearing up to release yet another Fermi GPU next month, plus three more in August and September.

July's piece of GPU action comes courtesy of the GeForce GTX 460. Previous rumours have already stated that the chip will be launched in mid-July, but tech website [H]ardOCP has now added a little bit more information.

The site confirms that the GeForce GTX 460 will be based on Nvidia's forthcoming GF104 chip, which is apparently going to be a good overclocker, and also says that cards based on the GPU will cost around $230 (£158).

Previous rumours have suggested that Nvidia's GF104 GPU can accommodate up to 256 stream processors, along with 64 texture units and 32 ROPs (render outputs).

Interestingly, however, the site also has some information on three new Fermi-based GPUs that it says will be turning up in August and September. According to the site, mid-August will see the arrival of the 450 and 455 chips, based on Nvidia's new GF106 core.

According to [H]ardOCP's sources, graphics cards based on these chips will sell for between $129 (£88) and $179 (£123), with the aim of replacing the current GeForce GTS 250 cards. Despite its model number, the GeForce GTX 250 is actually based on the same G92 core as the age-old GeForce 8800 GT, so a new GPU archircture is very much needed in Nvidia's mid-range segment now.

Finally, the site also claims that Nvidia has plans to release its GF108 core in August or September, with a view to replacing the GeForce GT 240, which is also based on Nvidia's old G92 core. Given Nvidia's usual naming strategy, we'd imagine that this chip will be called the GeForce GT 440.
