GeForce GTX 750 vs Radeon R9 M265X

Intro

The GeForce GTX 750 makes use of a 28 nm design. nVidia has set the core frequency at 1020 MHz. The GDDR5 memory runs at a speed of 1250 MHz on this specific model. It features 512 SPUs as well as 32 TAUs and 16 Rasterization Operator Units.

Compare that to the Radeon R9 M265X, which features a clock frequency of 575 MHz and a GDDR5 memory speed of 1125 MHz. It also makes use of a 128-bit bus, and uses a 28 nm design. It features 640 SPUs, 40 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce GTX 750 is 11% quicker than the Radeon R9 M265X overall, due to its greater bandwidth. (explain)

GeForce GTX 750 80000 MB/sec
Radeon R9 M265X 72000 MB/sec
Difference: 8000 (11%)

Texel Rate

The GeForce GTX 750 should be much (more or less 42%) more effective at texture filtering than the Radeon R9 M265X. (explain)

GeForce GTX 750 32640 Mtexels/sec
Radeon R9 M265X 23000 Mtexels/sec
Difference: 9640 (42%)

Pixel Rate

The GeForce GTX 750 should be a lot (more or less 77%) faster with regards to FSAA than the Radeon R9 M265X, and also should be able to handle higher resolutions without losing too much performance. (explain)

GeForce GTX 750 16320 Mpixels/sec
Radeon R9 M265X 9200 Mpixels/sec
Difference: 7120 (77%)

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. It's calculated by multiplying the card's interface width by its memory speed. If the card has DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total texture units 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 per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
