GeForce GTX 750 Ti vs Radeon R9 M385X

Intro

The GeForce GTX 750 Ti makes use of a 28 nm design. nVidia has clocked the core speed at 1020 MHz. The GDDR5 RAM works at a frequency of 1350 MHz on this specific model. It features 640 SPUs along with 40 TAUs and 16 Rasterization Operator Units.

Compare all of that to the Radeon R9 M385X, which features 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 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R9 M385X should perform a 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 should be a lot (approximately 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 running with a high resolution is important to you, then the Radeon R9 M385X is a better choice, but not by far. (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 largest amount of data (measured in megabytes per second) that can be transported past the external memory interface within a second. It's worked out by multiplying the interface width by its memory speed. If it uses DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better 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 texture map elements (texels) that are processed per 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 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 number of pixels the video card can possibly record to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
