GeForce GTX 750 vs Radeon R9 M270X

Intro

Compare all of that to the Radeon R9 M270X, which makes use of a 28 nm design. AMD has clocked the core speed at 725 MHz. The GDDR5 RAM is set to run at a frequency of 1125 MHz on this model. It features 640 SPUs as well as 40 Texture Address Units and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce GTX 750 should be 11% faster than the Radeon R9 M270X in general, because of its higher bandwidth. (explain)

GeForce GTX 750		80000 MB/sec
Radeon R9 M270X		72000 MB/sec
	Difference: 8000 (11%)

Texel Rate

The GeForce GTX 750 should be just a bit (approximately 13%) better at AF than the Radeon R9 M270X. (explain)

GeForce GTX 750		32640 Mtexels/sec
Radeon R9 M270X		29000 Mtexels/sec
	Difference: 3640 (13%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX 750 is the winner, by far. (explain)

GeForce GTX 750		16320 Mpixels/sec
Radeon R9 M270X		11600 Mpixels/sec
	Difference: 4720 (41%)

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 max amount of data (in units of MB per second) that can be moved across the external memory interface in a second. It's worked out by multiplying the card's bus width by its memory speed. If the card has DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly write to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs 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 output rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
