GeForce GTX 750 Ti 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 memory is set to run at a speed of 1125 MHz on this particular card. It features 640 SPUs along with 40 Texture Address Units and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the GeForce GTX 750 Ti should theoretically be a small bit superior to the Radeon R9 M270X in general. (explain)

GeForce GTX 750 Ti		86400 MB/sec
Radeon R9 M270X		72000 MB/sec
	Difference: 14400 (20%)

Texel Rate

The GeForce GTX 750 Ti will be quite a bit (about 41%) better at anisotropic filtering than the Radeon R9 M270X. (explain)

GeForce GTX 750 Ti		40800 Mtexels/sec
Radeon R9 M270X		29000 Mtexels/sec
	Difference: 11800 (41%)

Pixel Rate

The GeForce GTX 750 Ti should be quite a bit (more or less 41%) more effective at anti-aliasing than the Radeon R9 M270X, and also will be capable of handling higher resolutions while still performing well. (explain)

GeForce GTX 750 Ti		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 maximum amount of information (in units of MB per second) that can be moved across the external memory interface in one second. It's worked out by multiplying the card's bus width by its memory speed. If the card has DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's 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 are applied per second. This is calculated by multiplying the total amount of texture units by the core speed of the chip. The higher this number, 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 maximum number of pixels the video card could possibly record to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
