GeForce GTX 750 Ti vs Radeon R9 M385X

Intro

The GeForce GTX 750 Ti has a GPU core speed of 1020 MHz, and the 2048 MB of GDDR5 RAM is set to run at 1350 MHz through a 128-bit bus. It also is comprised of 640 SPUs, 40 TAUs, and 16 Raster Operation Units.

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

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon R9 M385X should in theory perform 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 should be much (approximately 51%) faster with regards to 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

The Radeon R9 M385X will be a small bit (more or less 8%) faster with regards to anti-aliasing than the GeForce GTX 750 Ti, and should be capable of handling higher screen resolutions without slowing down too much. (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 max amount of information (counted in MB per second) that can be moved past the external memory interface in one second. The number is worked out 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 DDR5, multiply by 4 instead. The better the memory bandwidth, the faster 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 processed per second. This figure is worked out by multiplying the total number of texture units by the core speed of the chip. The higher the texel rate, 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 most pixels the video card could possibly record to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the clock 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 fill rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
