GeForce GTX 750 Ti vs Radeon R9 M265X

Intro

Compare that to the Radeon R9 M265X, which makes use of a 28 nm design. AMD has clocked the core frequency at 575 MHz. The GDDR5 memory works at a frequency of 1125 MHz on this model. It features 640 SPUs along with 40 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically, the GeForce GTX 750 Ti should be a little 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 a lot (approximately 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 using lots of anti-aliasing is important to you, then the GeForce GTX 750 Ti is superior to the Radeon R9 M265X, by far. (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 max amount of information (measured in MB per second) that can be moved across the external memory interface within a second. It is worked out by multiplying the bus width by its memory speed. If it uses DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better 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 can be processed in one second. This figure is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels 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. Pixel rate is worked out by multiplying the amount of colour ROPs 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 also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
