GeForce GTX 480 vs Radeon R9 M375X

Intro

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

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce GTX 480 should perform quite a bit faster 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 a small bit (approximately 3%) better at AF than the Radeon R9 M375X. (explain)

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

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTX 480 is a better choice, 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 max amount of information (measured in megabytes per second) that can be transported past the external memory interface in one second. It's calculated by multiplying the card's bus width by its memory clock speed. If the card has DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, 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 applied per second. This number is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
