GeForce GTX 750 Ti vs Radeon R9 M385X

Intro

The GeForce GTX 750 Ti comes with a GPU core clock speed of 1020 MHz, and the 2048 MB of GDDR5 memory runs at 1350 MHz through a 128-bit bus. It also is made up of 640 Stream Processors, 40 Texture Address Units, and 16 Raster Operation Units.

Compare all of that to the Radeon R9 M385X, which features a GPU core clock speed of 1100 MHz, and 4096 MB of GDDR5 RAM set to run at 1500 MHz through a 128-bit bus. It also is comprised of 896 SPUs, 56 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R9 M385X should be 11% quicker than the GeForce GTX 750 Ti in general, 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 will be much (approximately 51%) more effective 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 running with high levels of AA 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.

Memory Bandwidth: Memory bandwidth is the maximum amount of data (counted in MB per second) that can be moved across the external memory interface within a second. It is worked out by multiplying the bus width by its memory clock speed. In the case of DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. 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 potential to get to the max fill rate.
