GeForce GTX 460 SE vs Radeon R9 M265X

Intro

Compare that to the Radeon R9 M265X, which has core speeds of 575 MHz on the GPU, and 1125 MHz on the 2048 MB of GDDR5 memory. It features 640 SPUs along with 40 TAUs and 16 ROPs.

Radeon R9 M265X		72000 MB/sec
	Difference: 36800 (51%)

Texel Rate

The GeForce GTX 460 SE should be quite a bit (more or less 36%) faster with regards to AF than the Radeon R9 M265X. (explain)

GeForce GTX 460 SE		31200 Mtexels/sec
Radeon R9 M265X		23000 Mtexels/sec
	Difference: 8200 (36%)

Pixel Rate

The GeForce GTX 460 SE should be quite a bit (more or less 126%) more effective at FSAA than the Radeon R9 M265X, and should be capable of handling higher screen resolutions more effectively. (explain)

GeForce GTX 460 SE		20800 Mpixels/sec
Radeon R9 M265X		9200 Mpixels/sec
	Difference: 11600 (126%)

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.

Specifications

Memory Bandwidth: Bandwidth is the max amount of data (counted in MB per second) that can be moved across the external memory interface in a second. The number is worked out by multiplying the card's interface width by the speed of its memory. In the case of DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This figure is calculated by multiplying the total number of texture units of the card 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 per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
