GeForce GTX 750 Ti vs Radeon R9 M295X

Intro

Compare all that to the Radeon R9 M295X, which makes use of a 28 nm design. AMD has set the core frequency at 750 MHz. The GDDR5 memory runs at a speed of 1375 MHz on this specific card. It features 2048 SPUs along with 128 TAUs and 32 Rasterization Operator Units.

Theoretically speaking, the Radeon R9 M295X should be 104% quicker than the GeForce GTX 750 Ti in general, due to its higher data rate. (explain)

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

Texel Rate

The Radeon R9 M295X is a lot (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

The Radeon R9 M295X should be much (more or less 47%) better at AA than the GeForce GTX 750 Ti, and also should be capable of handling higher 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: Bandwidth is the maximum amount of information (in units of megabytes per second) that can be transported past the external memory interface within a second. It's calculated by multiplying the card's bus width by its memory clock speed. In the case of DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
