GeForce GTX 460 vs Radeon R9 M265X

Intro

The GeForce GTX 460 comes with a core clock frequency of 675 MHz and a GDDR5 memory speed of 900 MHz. It also uses a 192-bit bus, and uses a 40 nm design. It is made up of 336 SPUs, 56 TAUs, and 24 Raster Operation Units.

Compare those specs to the Radeon R9 M265X, which features GPU clock speed of 575 MHz, and 2048 MB of GDDR5 RAM running at 1125 MHz through a 128-bit bus. It also is made up of 640 SPUs, 40 Texture Address Units, and 16 Raster Operation Units.

GeForce GTX 460 37800 Mtexels/sec
Radeon R9 M265X 23000 Mtexels/sec
Difference: 14800 (64%)

Pixel Rate

The GeForce GTX 460 will be a lot (approximately 76%) more effective at FSAA than the Radeon R9 M265X, and will be able to handle higher screen resolutions better. (explain)

GeForce GTX 460 16200 Mpixels/sec
Radeon R9 M265X 9200 Mpixels/sec
Difference: 7000 (76%)

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 moved past the external memory interface within a second. It is calculated by multiplying the interface width by its memory clock speed. If it uses DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

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