GeForce GTX 750 Ti vs Radeon R9 M270X

Intro

Compare all that to the Radeon R9 M270X, which has a clock frequency of 725 MHz and a GDDR5 memory speed of 1125 MHz. It also features a 128-bit memory bus, and makes use of a 28 nm design. It is comprised of 640 SPUs, 40 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce GTX 750 Ti will be 20% faster than the Radeon R9 M270X in general, because of its greater data rate. (explain)

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

Texel Rate

The GeForce GTX 750 Ti is a lot (more or less 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 will be quite a bit (approximately 41%) better at anti-aliasing than the Radeon R9 M270X, and also will be able to handle higher resolutions without slowing down too much. (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: Memory bandwidth is the max amount of information (in units of megabytes per second) that can be moved across the external memory interface in one second. It is calculated by multiplying the interface width by the speed of its memory. If it uses DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This number is calculated by multiplying the total amount of texture units of the card by the core clock 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 in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to the 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 card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
