GeForce GTX 750 Ti vs Radeon R9 M385X

Intro

Compare all of that to the Radeon R9 M385X, which comes with clock speeds of 1100 MHz on the GPU, and 1500 MHz on the 4096 MB of GDDR5 memory. It features 896 SPUs along with 56 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R9 M385X will be 11% faster than the GeForce GTX 750 Ti overall, because of its greater bandwidth. (explain)

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

Texel Rate

The Radeon R9 M385X is a lot (about 51%) better at AF 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 a high resolution is important to you, then the Radeon R9 M385X is a better choice, 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 maximum amount of data (measured in megabytes per second) that can be moved over the external memory interface within a second. It's worked out by multiplying the bus width by its memory speed. If it uses 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 amount of texture map elements (texels) that can be processed in one second. This figure 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 video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

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