GeForce GTX 480 vs Radeon R9 M375X

Intro

Compare all of that to the Radeon R9 M375X, which comes with clock speeds of 1015 MHz on the GPU, and 1125 MHz on the 4096 MB of GDDR5 RAM. It features 640 SPUs along with 40 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the GeForce GTX 480 should in theory be a lot better than the Radeon R9 M375X overall. (explain)

GeForce GTX 480		177408 MB/sec
Radeon R9 M375X		72000 MB/sec
	Difference: 105408 (146%)

Texel Rate

The GeForce GTX 480 should be just a bit (approximately 3%) faster with regards to anisotropic filtering than the Radeon R9 M375X. (explain)

GeForce GTX 480		42000 Mtexels/sec
Radeon R9 M375X		40600 Mtexels/sec
	Difference: 1400 (3%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX 480 is the winner, by far. (explain)

GeForce GTX 480		33600 Mpixels/sec
Radeon R9 M375X		16240 Mpixels/sec
	Difference: 17360 (107%)

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 (counted in megabytes per second) that can be transferred past the external memory interface in one second. It's calculated by multiplying the card's bus width by its memory speed. If it uses DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's 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 number of texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total texture units of the card by the core speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. The figure 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, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
