GeForce GTX 750 vs Radeon R9 M265X

Intro

Compare all of that to the Radeon R9 M265X, which uses a 28 nm design. AMD has set the core frequency at 575 MHz. The GDDR5 RAM is set to run at a speed of 1125 MHz on this specific model. It features 640 SPUs as well as 40 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce GTX 750 should theoretically perform a little bit faster than the Radeon R9 M265X overall. (explain)

GeForce GTX 750		80000 MB/sec
Radeon R9 M265X		72000 MB/sec
	Difference: 8000 (11%)

Texel Rate

The GeForce GTX 750 will be much (about 42%) faster with regards to texture filtering than the Radeon R9 M265X. (explain)

GeForce GTX 750		32640 Mtexels/sec
Radeon R9 M265X		23000 Mtexels/sec
	Difference: 9640 (42%)

Pixel Rate

The GeForce GTX 750 will be a lot (approximately 77%) more effective at FSAA than the Radeon R9 M265X, and also should be able to handle higher screen resolutions while still performing well. (explain)

GeForce GTX 750		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 data (counted in megabytes per second) that can be transported past the external memory interface in a second. The number is worked out by multiplying the card's interface width by its memory speed. In the case of DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total texture units of the card 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 applied in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels 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 number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
