GeForce GTX 460 1GB vs GeForce GTX 560

Intro

The GeForce GTX 460 1GB comes with clock speeds of 675 MHz on the GPU, and 900 MHz on the 1024 MB of GDDR5 RAM. It features 336 SPUs along with 56 Texture Address Units and 32 Rasterization Operator Units.

Compare those specifications to the GeForce GTX 560, which comes with a GPU core clock speed of 810 MHz, and 1024 MB of GDDR5 RAM running at 1001 MHz through a 256-bit bus. It also is comprised of 336 SPUs, 56 TAUs, and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 560 150 Watts
GeForce GTX 460 1GB 160 Watts
Difference: 10 Watts (7%)

Memory Bandwidth

As far as performance goes, the GeForce GTX 560 should theoretically be a bit better than the GeForce GTX 460 1GB in general. (explain)

GeForce GTX 560 128128 MB/sec
GeForce GTX 460 1GB 115200 MB/sec
Difference: 12928 (11%)

Texel Rate

The GeForce GTX 560 should be just a bit (approximately 20%) better at texture filtering than the GeForce GTX 460 1GB. (explain)

GeForce GTX 560 45360 Mtexels/sec
GeForce GTX 460 1GB 37800 Mtexels/sec
Difference: 7560 (20%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce GTX 560 is the winner, but it probably won't make a huge difference. (explain)

GeForce GTX 560 25920 Mpixels/sec
GeForce GTX 460 1GB 21600 Mpixels/sec
Difference: 4320 (20%)

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 largest amount of data (in units of megabytes per second) that can be transported across the external memory interface in a second. It's calculated by multiplying the bus width by the speed of its memory. In the case of DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This number is worked out by multiplying the total texture units of the card by the core 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 in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to the 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 card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
