GeForce GTX 750 Ti vs Radeon R9 M295X

Intro

Compare all of that to the Radeon R9 M295X, which uses a 28 nm design. AMD has clocked the core frequency at 750 MHz. The GDDR5 RAM runs at a frequency of 1375 MHz on this model. It features 2048 SPUs along with 128 TAUs and 32 Rasterization Operator Units.

GeForce GTX 750 Ti		60 Watts
Radeon R9 M295X		125 Watts
	Difference: 65 Watts (108%)

Memory Bandwidth

Theoretically, the Radeon R9 M295X should be much faster than the GeForce GTX 750 Ti in general. (explain)

Radeon R9 M295X		176000 MB/sec
GeForce GTX 750 Ti		86400 MB/sec
	Difference: 89600 (104%)

Texel Rate

The Radeon R9 M295X is quite a bit (more or less 135%) more effective at AF than the GeForce GTX 750 Ti. (explain)

Radeon R9 M295X		96000 Mtexels/sec
GeForce GTX 750 Ti		40800 Mtexels/sec
	Difference: 55200 (135%)

Pixel Rate

If using a high screen resolution is important to you, then the Radeon R9 M295X is a better choice, by far. (explain)

Radeon R9 M295X		24000 Mpixels/sec
GeForce GTX 750 Ti		16320 Mpixels/sec
	Difference: 7680 (47%)

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 largest amount of data (in units of MB per second) that can be moved across the external memory interface in a second. The number is calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This number is worked out by multiplying the total texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the most pixels that the graphics 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 colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
