GeForce GTX 750 Ti vs Radeon R9 M380

Intro

The GeForce GTX 750 Ti features a GPU core speed of 1020 MHz, and the 2048 MB of GDDR5 RAM is set to run at 1350 MHz through a 128-bit bus. It also is made up of 640 SPUs, 40 Texture Address Units, and 16 Raster Operation Units.

Compare that to the Radeon R9 M380, which comes with GPU core speed of 1000 MHz, and 4096 MB of GDDR5 memory running at 1500 MHz through a 128-bit bus. It also features 640 Stream Processors, 40 TAUs, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R9 M380 will be 11% faster than the GeForce GTX 750 Ti in general, due to its greater bandwidth. (explain)

Radeon R9 M380 96000 MB/sec
GeForce GTX 750 Ti 86400 MB/sec
Difference: 9600 (11%)

Texel Rate

The GeForce GTX 750 Ti should be a little bit (more or less 2%) more effective at texture filtering than the Radeon R9 M380. (explain)

GeForce GTX 750 Ti 40800 Mtexels/sec
Radeon R9 M380 40000 Mtexels/sec
Difference: 800 (2%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 750 Ti is superior to the Radeon R9 M380, though not by far. (explain)

GeForce GTX 750 Ti 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: Bandwidth is the largest amount of information (measured in MB per second) that can be transported across the external memory interface in one second. The number is calculated by multiplying the bus width by its memory speed. If the card has DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number 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 rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
