GeForce GTX 750 Ti vs Radeon R9 M385X

Intro

The GeForce GTX 750 Ti features a GPU core clock speed of 1020 MHz, and the 2048 MB of GDDR5 RAM runs at 1350 MHz through a 128-bit bus. It also is comprised of 640 SPUs, 40 Texture Address Units, and 16 Raster Operation Units.

Compare those specs to the Radeon R9 M385X, which makes use of a 28 nm design. AMD has set the core speed at 1100 MHz. The GDDR5 memory works at a speed of 1500 MHz on this specific model. It features 896 SPUs along with 56 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon R9 M385X should in theory be a small bit faster than the GeForce GTX 750 Ti overall. (explain)

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

Texel Rate

The Radeon R9 M385X will be much (more or less 51%) better at texture 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 high levels of AA is important to you, then the Radeon R9 M385X is the winner, not by a very large margin though. (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.

Memory Bandwidth: Bandwidth is the maximum amount of information (counted in megabytes per second) that can be moved past the external memory interface in a second. It's calculated by multiplying the bus width by its memory clock speed. If the card has DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the 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 most pixels that the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
