GeForce GTS 250 512MB vs Radeon R9 M375X

Intro

Compare all of that to the Radeon R9 M375X, which has core 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

In theory, the Radeon R9 M375X will be 2% quicker than the GeForce GTS 250 512MB overall, because of its greater bandwidth. (explain)

Radeon R9 M375X		72000 MB/sec
GeForce GTS 250 512MB		70400 MB/sec
	Difference: 1600 (2%)

Texel Rate

The GeForce GTS 250 512MB should be a small bit (about 16%) faster with regards to texture filtering than the Radeon R9 M375X. (explain)

GeForce GTS 250 512MB		47232 Mtexels/sec
Radeon R9 M375X		40600 Mtexels/sec
	Difference: 6632 (16%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon R9 M375X is the winner, and very much so. (explain)

Radeon R9 M375X		16240 Mpixels/sec
GeForce GTS 250 512MB		11808 Mpixels/sec
	Difference: 4432 (38%)

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 (in units of megabytes per second) that can be transported past the external memory interface in one second. It is calculated by multiplying the interface width by its memory speed. If the card has DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This figure is worked out by multiplying the total texture units by the core clock speed of the chip. The better this number, the better the video 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 most pixels that the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the the core speed of the card. 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 fill rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
