GeForce GTX 750 Ti vs Radeon R9 M385X

Intro

Compare those specifications to the Radeon R9 M385X, which has clock speeds of 1100 MHz on the GPU, and 1500 MHz on the 4096 MB of GDDR5 RAM. It features 896 SPUs as well as 56 Texture Address Units and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R9 M385X should perform just a bit faster than the GeForce GTX 750 Ti in general. (explain)

Radeon R9 M385X		96000 MB/sec
GeForce GTX 750 Ti		86400 MB/sec
	Difference: 9600 (11%)

Texel Rate

The Radeon R9 M385X is quite a bit (more or less 51%) better at anisotropic filtering than the GeForce GTX 750 Ti. (explain)

Radeon R9 M385X		61600 Mtexels/sec
GeForce GTX 750 Ti		40800 Mtexels/sec
	Difference: 20800 (51%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon R9 M385X is superior to the GeForce GTX 750 Ti, but only just. (explain)

Radeon R9 M385X		17600 Mpixels/sec
GeForce GTX 750 Ti		16320 Mpixels/sec
	Difference: 1280 (8%)

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 max amount of data (in units of MB per second) that can be moved across the external memory interface in a second. It's worked out by multiplying the bus width by its memory speed. In the case of DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen 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 clock speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the the core 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 output rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
