GeForce GTX 460 SE vs GeForce GTX 470

Intro

The GeForce GTX 460 SE has a clock frequency of 650 MHz and a GDDR5 memory speed of 850 MHz. It also makes use of a 256-bit memory bus, and makes use of a 40 nm design. It is comprised of 288 SPUs, 48 TAUs, and 32 Raster Operation Units.

Compare all that to the GeForce GTX 470, which features a core clock speed of 607 MHz and a GDDR5 memory frequency of 837 MHz. It also uses a 320-bit memory bus, and makes use of a 40 nm design. It features 448 SPUs, 56 TAUs, and 40 Raster Operation Units.

GeForce GTX 460 SE 108800 MB/sec
Difference: 25120 (23%)

Texel Rate

The GeForce GTX 470 is just a bit (more or less 9%) better at AF than the GeForce GTX 460 SE. (explain)

GeForce GTX 470 33992 Mtexels/sec
GeForce GTX 460 SE 31200 Mtexels/sec
Difference: 2792 (9%)

Pixel Rate

If using a high resolution is important to you, then the GeForce GTX 470 is the winner, but it probably won't make a huge difference. (explain)

GeForce GTX 470 24280 Mpixels/sec
GeForce GTX 460 SE 20800 Mpixels/sec
Difference: 3480 (17%)

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: Bandwidth is the max amount of data (measured in megabytes per second) that can be transferred across the external memory interface in a second. It's calculated by multiplying the card's interface width by its memory clock speed. If the card has DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
