Geforce GTX 670 vs Radeon R9 M375

Intro

Compare all of that to the Radeon R9 M375, which comes with a GPU core clock speed of 1015 MHz, and 4096 MB of DDR3 memory set to run at 1100 MHz through a 128-bit bus. It also is comprised of 640 SPUs, 40 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Geforce GTX 670 is 445% quicker than the Radeon R9 M375 in general, because of its greater data rate. (explain)

Geforce GTX 670		192000 MB/sec
Radeon R9 M375		35200 MB/sec
	Difference: 156800 (445%)

Texel Rate

The Geforce GTX 670 should be quite a bit (approximately 152%) better at texture filtering than the Radeon R9 M375. (explain)

Geforce GTX 670		102480 Mtexels/sec
Radeon R9 M375		40600 Mtexels/sec
	Difference: 61880 (152%)

Pixel Rate

The Geforce GTX 670 will be quite a bit (approximately 80%) better at full screen anti-aliasing than the Radeon R9 M375, and will be capable of handling higher screen resolutions without losing too much performance. (explain)

Geforce GTX 670		29280 Mpixels/sec
Radeon R9 M375		16240 Mpixels/sec
	Difference: 13040 (80%)

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 largest amount of data (counted in MB per second) that can be transported across the external memory interface in one second. It's worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher 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 amount of texture map elements (texels) that are applied in one second. This number is worked out by multiplying the total texture units by the core 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 processed per second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly write to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
