GeForce GTX 750 Ti vs Radeon R9 M265X

Intro

Compare all of that to the Radeon R9 M265X, which features a clock speed of 575 MHz and a GDDR5 memory speed of 1125 MHz. It also makes use of a 128-bit bus, and makes use of a 28 nm design. It is comprised of 640 SPUs, 40 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically, the GeForce GTX 750 Ti should be a small bit faster than the Radeon R9 M265X in general. (explain)

GeForce GTX 750 Ti		86400 MB/sec
Radeon R9 M265X		72000 MB/sec
	Difference: 14400 (20%)

Texel Rate

The GeForce GTX 750 Ti is much (about 77%) faster with regards to anisotropic filtering than the Radeon R9 M265X. (explain)

GeForce GTX 750 Ti		40800 Mtexels/sec
Radeon R9 M265X		23000 Mtexels/sec
	Difference: 17800 (77%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 750 Ti is the winner, by a large margin. (explain)

GeForce GTX 750 Ti		16320 Mpixels/sec
Radeon R9 M265X		9200 Mpixels/sec
	Difference: 7120 (77%)

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 (measured in megabytes per second) that can be moved past the external memory interface within a second. It is worked out by multiplying the bus width by the speed of its memory. If it uses DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount 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 output rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
