GeForce GTX 660 Ti vs Radeon R9 M375

Intro

Compare those specs to the Radeon R9 M375, which has clock speeds of 1015 MHz on the GPU, and 1100 MHz on the 4096 MB of DDR3 RAM. It features 640 SPUs as well as 40 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce GTX 660 Ti should be a lot faster than the Radeon R9 M375 in general. (explain)

GeForce GTX 660 Ti		144000 MB/sec
Radeon R9 M375		35200 MB/sec
	Difference: 108800 (309%)

Texel Rate

The GeForce GTX 660 Ti should be quite a bit (approximately 152%) more effective at texture filtering than the Radeon R9 M375. (explain)

GeForce GTX 660 Ti		102480 Mtexels/sec
Radeon R9 M375		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, and very much so. (explain)

GeForce GTX 660 Ti		21960 Mpixels/sec
Radeon R9 M375		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. The number is worked out by multiplying the card's interface width by the speed of its memory. If the card has DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This is worked out by multiplying the total texture units by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
