GeForce GTX 660 Ti vs Radeon R9 M375X

Intro

Compare those specs to the Radeon R9 M375X, which has GPU core speed of 1015 MHz, and 4096 MB of GDDR5 memory running at 1125 MHz through a 128-bit bus. It also is made up of 640 Stream Processors, 40 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce GTX 660 Ti will be 100% faster than the Radeon R9 M375X overall, due to its greater data rate. (explain)

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

Texel Rate

The GeForce GTX 660 Ti is a lot (more or less 152%) more effective at 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 using a high screen resolution is important to you, then the GeForce GTX 660 Ti is superior to the Radeon R9 M375X, and very much so. (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: Memory bandwidth is the maximum amount of information (measured in megabytes per second) that can be moved across the external memory interface in a second. It is worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, 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 number of texture map elements (texels) that can be applied per second. This figure is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of 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 rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
