GeForce GTX 750 Ti vs Radeon R9 M295X

Intro

Compare all of that to the Radeon R9 M295X, which makes use of a 28 nm design. AMD has clocked the core frequency at 750 MHz. The GDDR5 RAM is set to run at a frequency of 1375 MHz on this particular card. It features 2048 SPUs as well as 128 Texture Address Units and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

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

Memory Bandwidth

As far as performance goes, the Radeon R9 M295X should in theory be a lot superior to 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 should be quite a bit (more or less 135%) better at anisotropic filtering 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

The Radeon R9 M295X is much (approximately 47%) more effective at FSAA than the GeForce GTX 750 Ti, and also should be able to handle higher screen resolutions while still performing well. (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 information (counted in MB per second) that can be moved across the external memory interface in one second. It's calculated by multiplying the interface width by the speed of its memory. In the case of DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the 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 number of texture map elements (texels) that can be applied per second. This number is calculated by multiplying the total number of texture units by the core speed of the chip. The better the texel rate, the better the 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 chip could possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
