GeForce GTX 465 vs GeForce GTX 560

Intro

The GeForce GTX 465 features a clock speed of 607 MHz and a GDDR5 memory frequency of 802 MHz. It also features a 256-bit memory bus, and makes use of a 40 nm design. It features 352 SPUs, 44 TAUs, and 32 ROPs.

Compare all of that to the GeForce GTX 560, which uses a 40 nm design. nVidia has clocked the core frequency at 810 MHz. The GDDR5 RAM runs at a frequency of 1001 MHz on this particular model. It features 336 SPUs as well as 56 Texture Address Units and 32 ROPs.

GeForce GTX 560 45360 Mtexels/sec
GeForce GTX 465 26708 Mtexels/sec
Difference: 18652 (70%)

Pixel Rate

The GeForce GTX 560 should be quite a bit (about 33%) better at full screen anti-aliasing than the GeForce GTX 465, and also able to handle higher screen resolutions without slowing down too much. (explain)

GeForce GTX 560 25920 Mpixels/sec
GeForce GTX 465 19424 Mpixels/sec
Difference: 6496 (33%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Memory Bandwidth: Memory bandwidth is the maximum amount of data (measured in MB per second) that can be transferred over the external memory interface in one second. The number is worked out by multiplying the card's interface width by its memory speed. If it uses DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This number is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
