GeForce GTX 260 vs GeForce GTX 470

Intro

The GeForce GTX 260 has a core clock frequency of 576 MHz and a GDDR3 memory frequency of 999 MHz. It also makes use of a 448-bit bus, and makes use of a 65 nm design. It is made up of 192 SPUs, 64 TAUs, and 28 Raster Operation Units.

Compare that to the GeForce GTX 470, which makes use of a 40 nm design. nVidia has set the core speed at 607 MHz. The GDDR5 memory runs at a frequency of 837 MHz on this particular model. It features 448 SPUs along with 56 TAUs and 40 ROPs.

GeForce GTX 470 133920 MB/sec
GeForce GTX 260 111888 MB/sec
Difference: 22032 (20%)

Texel Rate

The GeForce GTX 260 should be a small bit (about 8%) better at AF than the GeForce GTX 470. (explain)

GeForce GTX 260 36864 Mtexels/sec
GeForce GTX 470 33992 Mtexels/sec
Difference: 2872 (8%)

Pixel Rate

The GeForce GTX 470 will be quite a bit (about 51%) more effective at FSAA than the GeForce GTX 260, and also should be capable of handling higher screen resolutions while still performing well. (explain)

GeForce GTX 470 24280 Mpixels/sec
GeForce GTX 260 16128 Mpixels/sec
Difference: 8152 (51%)

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 max amount of information (in units of MB per second) that can be moved past the external memory interface in one second. The number is worked out by multiplying the card's interface width by its memory clock speed. In the case of DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better 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 texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

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