GeForce GTX 650 vs Radeon R9 M375X

Intro

The GeForce GTX 650 has a clock speed of 1058 MHz and a GDDR5 memory speed of 1250 MHz. It also uses a 128-bit memory bus, and makes use of a 28 nm design. It is comprised of 384 SPUs, 32 TAUs, and 16 Raster Operation Units.

Compare those specifications to the Radeon R9 M375X, which makes use of a 28 nm design. AMD has clocked the core speed at 1015 MHz. The GDDR5 memory runs at a speed of 1125 MHz on this card. It features 640 SPUs as well as 40 Texture Address Units and 16 Rasterization Operator Units.

The GeForce GTX 650, in theory, should perform a bit faster than the Radeon R9 M375X in general. (explain)

GeForce GTX 650 80000 MB/sec
Radeon R9 M375X 72000 MB/sec
Difference: 8000 (11%)

Texel Rate

The Radeon R9 M375X will be a little bit (about 20%) better at anisotropic filtering than the GeForce GTX 650. (explain)

Radeon R9 M375X 40600 Mtexels/sec
GeForce GTX 650 33856 Mtexels/sec
Difference: 6744 (20%)

Pixel Rate

The GeForce GTX 650 should be a small bit (about 4%) more effective at AA than the Radeon R9 M375X, and will be able to handle higher resolutions better. (explain)

GeForce GTX 650 16928 Mpixels/sec
Radeon R9 M375X 16240 Mpixels/sec
Difference: 688 (4%)

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 information (measured in MB per second) that can be transferred over the external memory interface in one second. The number is worked out by multiplying the bus width by the speed of its memory. If it uses DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The higher 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 that the graphics card can possibly write to its 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 the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
