GeForce GTX 750 Ti vs Radeon R9 M385X

Intro

The GeForce GTX 750 Ti has a clock frequency of 1020 MHz and a GDDR5 memory frequency of 1350 MHz. It also uses a 128-bit bus, and uses a 28 nm design. It is comprised of 640 SPUs, 40 TAUs, and 16 ROPs.

Compare those specs to the Radeon R9 M385X, which features a clock frequency of 1100 MHz and a GDDR5 memory frequency of 1500 MHz. It also features a 128-bit bus, and makes use of a 28 nm design. It features 896 SPUs, 56 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon R9 M385X should in theory be 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 a lot (about 51%) faster with regards to 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 screen resolution is important to you, then the Radeon R9 M385X is superior to the GeForce GTX 750 Ti, though 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: Bandwidth is the largest amount of data (measured in megabytes per second) that can be moved over the external memory interface in a second. The number is worked out by multiplying the bus width by its memory clock speed. If it uses DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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