NVIDIA GTX 465: A Mainstream Version of NVIDIA Fermi

One day before the start of Computex 2010 in Taipei, NVIDIA launched its first mainstream DirectX 11 GPU, the GeForce GTX 465. Naming wise, this particular GPU is positioned below the GTX 470, but it’s based on the same Fermi architecture. That would give it all the features of the GT 100, except the speed of course. It’s not too far off from the release of high-end Fermis, so it looks like NVIDIA wanted to act fast and close the gap in mainstream market segments. Perhaps we can expect to see other variations of Fermi within the next couple of months as well.

Compared to its higher end siblings, the GTX 465 is a bit lacking when it comes to technical prowess. Its video memory amount/ interface, and stream processor number are all reduced to distinguish it from the flagship GTXs. The GTX 480 and GTX 470 are 32-stream processors apart, the gap widens to 96 stream processors, between the GTX 470 and GTX 465.

The GeForce GTX 465 has every bit of features supported by the Fermi family of GPUs. It needs at least a 550 watt PSU, which puts it on a par with the GeForce GTX 470 in term of power requirement.
