Radeon R9 M375		35200 MB/sec
	Difference: 73600 (209%)

Texel Rate

The Radeon R9 M375 should be quite a bit (more or less 30%) faster with regards to anisotropic filtering than the GeForce GTX 460 SE. (explain)

Radeon R9 M375		40600 Mtexels/sec
GeForce GTX 460 SE		31200 Mtexels/sec
	Difference: 9400 (30%)

Pixel Rate

The GeForce GTX 460 SE should be a lot (approximately 28%) more effective at full screen anti-aliasing than the Radeon R9 M375, and also will be capable of handling higher resolutions better. (explain)

GeForce GTX 460 SE		20800 Mpixels/sec
Radeon R9 M375		16240 Mpixels/sec
	Difference: 4560 (28%)

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 largest amount of data (counted in megabytes per second) that can be moved past the external memory interface in a second. It is worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This figure is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the video card will be at 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 the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel 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 ability to reach the max fill rate.
