GeForce GTX 750 vs Radeon R9 M380

Intro

The GeForce GTX 750 features a GPU core speed of 1020 MHz, and the 1024 MB of GDDR5 memory runs at 1250 MHz through a 128-bit bus. It also is comprised of 512 SPUs, 32 Texture Address Units, and 16 Raster Operation Units.

Compare those specifications to the Radeon R9 M380, which comes with clock speeds of 1000 MHz on the GPU, and 1500 MHz on the 4096 MB of GDDR5 memory. It features 640 SPUs along with 40 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the Radeon R9 M380 should in theory be a little bit superior to the GeForce GTX 750 overall. (explain)

Radeon R9 M380 96000 MB/sec
GeForce GTX 750 80000 MB/sec
Difference: 16000 (20%)

Texel Rate

The Radeon R9 M380 will be quite a bit (more or less 23%) more effective at texture filtering than the GeForce GTX 750. (explain)

Radeon R9 M380 40000 Mtexels/sec
GeForce GTX 750 32640 Mtexels/sec
Difference: 7360 (23%)

Pixel Rate

If using a high resolution is important to you, then the GeForce GTX 750 is superior to the Radeon R9 M380, not by a very large margin though. (explain)

GeForce GTX 750 16320 Mpixels/sec
Radeon R9 M380 16000 Mpixels/sec
Difference: 320 (2%)

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 (counted in MB per second) that can be moved across the external memory interface within a second. The number is worked out by multiplying the bus width by its memory clock speed. If the card has DDR type RAM, it should 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 anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This is calculated by multiplying the total texture units by the core speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
