GeForce GTX 460 vs Radeon R9 M375

Intro

Compare that to the Radeon R9 M375, which features clock speeds of 1015 MHz on the GPU, and 1100 MHz on the 4096 MB of DDR3 RAM. It features 640 SPUs along with 40 Texture Address Units and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce GTX 460 should in theory perform a lot faster than the Radeon R9 M375 in general. (explain)

GeForce GTX 460		86400 MB/sec
Radeon R9 M375		35200 MB/sec
	Difference: 51200 (145%)

Texel Rate

The Radeon R9 M375 will be a little bit (about 7%) faster with regards to anisotropic filtering than the GeForce GTX 460. (explain)

Radeon R9 M375		40600 Mtexels/sec
GeForce GTX 460		37800 Mtexels/sec
	Difference: 2800 (7%)

Pixel Rate

If running with a high resolution is important to you, then the Radeon R9 M375 is a better choice, but it probably won't make a huge difference. (explain)

Radeon R9 M375		16240 Mpixels/sec
GeForce GTX 460		16200 Mpixels/sec
	Difference: 40 (0%)

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: Memory bandwidth is the maximum amount of data (measured in MB per second) that can be moved across the external memory interface within a second. It is calculated by multiplying the card's bus width by its memory speed. If it uses DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, 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 can be processed per second. This number is calculated by multiplying the total texture units 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 in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to its 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 - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
