GeForce GTX 460 (OEM) vs Radeon R9 M375X

Intro

Compare all that to the Radeon R9 M375X, which features core speeds of 1015 MHz on the GPU, and 1125 MHz on the 4096 MB of GDDR5 memory. It features 640 SPUs as well as 40 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce GTX 460 (OEM) should theoretically be quite a bit faster than the Radeon R9 M375X overall. (explain)

GeForce GTX 460 (OEM)		108800 MB/sec
Radeon R9 M375X		72000 MB/sec
	Difference: 36800 (51%)

Texel Rate

The Radeon R9 M375X is just a bit (about 12%) better at anisotropic filtering than the GeForce GTX 460 (OEM). (explain)

Radeon R9 M375X		40600 Mtexels/sec
GeForce GTX 460 (OEM)		36400 Mtexels/sec
	Difference: 4200 (12%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX 460 (OEM) is the winner, and very much so. (explain)

GeForce GTX 460 (OEM)		20800 Mpixels/sec
Radeon R9 M375X		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 information (measured in MB per second) that can be transferred past the external memory interface in a second. It's worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster 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 applied per second. This is calculated by multiplying the total number of texture units by the core clock speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

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