GeForce GTX 660 Ti vs Radeon R9 M375X

Intro

Compare all of 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 RAM. It features 640 SPUs as well as 40 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce GTX 660 Ti will be 100% faster than the Radeon R9 M375X overall, due to its greater bandwidth. (explain)

GeForce GTX 660 Ti		144000 MB/sec
Radeon R9 M375X		72000 MB/sec
	Difference: 72000 (100%)

Texel Rate

The GeForce GTX 660 Ti should be quite a bit (more or less 152%) faster with regards to texture filtering than the Radeon R9 M375X. (explain)

GeForce GTX 660 Ti		102480 Mtexels/sec
Radeon R9 M375X		40600 Mtexels/sec
	Difference: 61880 (152%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce GTX 660 Ti is the winner, by far. (explain)

GeForce GTX 660 Ti		21960 Mpixels/sec
Radeon R9 M375X		16240 Mpixels/sec
	Difference: 5720 (35%)

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 maximum amount of data (in units of megabytes per second) that can be transported over the external memory interface in one second. It is worked out by multiplying the interface width by the speed of its memory. If the card has DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This number is calculated by multiplying the total amount of texture units by the core clock 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 in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly write to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs 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 fill rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
