What Do We Think?
The new NVIDIA GeForce GTX 465 looks and feels exactly like the more expensive GeForce GTX 470. However, it is not the GeForce GTX 470.
Despite the similarity, the GeForce GTX 465 is significantly slower than the GeForce GTX 470. It has 12 fewer texture units and 8 fewer ROP units. That's 21.4% and 20% lower performance in texture and pixel fillrate, even at the same clock speed. Too bad the reduction in stream processors did not translate into a similar reduction in power consumption - the board TDP only fell by 15 W, or just 7%.
The GeForce GTX 465 also has a narrower memory interface that is just 256-bits wide. That's 64-bits (20%) less than the GeForce GTX 470's 320-bit memory interface. Coupled with a slightly (4.2%) lower memory clock speed, the GeForce GTX 465 ends up with 23.4% less memory bandwidth than the GeForce GTX 470.
The NVIDIA GeForce GTX 465 ended up about 20-25% slower than the GeForce GTX 470 in NVIDIA's own benchmark results. When pitted against the heavyweight GeForce GTX 480, the GeForce GTX 465 was 30-38% slower.
The moral of this story? Looks are deceiving, and so are small number changes. IMHO, this card should have been called the GeForce GTX 460.
