GeForce GTX 750 vs Radeon R9 M380

Intro

The GeForce GTX 750 uses a 28 nm design. nVidia has set the core frequency at 1020 MHz. The GDDR5 memory is set to run at a frequency of 1250 MHz on this specific model. It features 512 SPUs as well as 32 Texture Address Units and 16 Rasterization Operator Units.

Compare all of that to the Radeon R9 M380, which has a clock frequency of 1000 MHz and a GDDR5 memory frequency of 1500 MHz. It also features a 128-bit memory bus, and makes use of a 28 nm design. It is made up of 640 SPUs, 40 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R9 M380 will be 20% quicker than the GeForce GTX 750 overall, due to its greater bandwidth. (explain)

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

Texel Rate

The Radeon R9 M380 should be much (about 23%) better at AF than the GeForce GTX 750. (explain)

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

Pixel Rate

The GeForce GTX 750 should be a little bit (more or less 2%) faster with regards to AA than the Radeon R9 M380, and also should be capable of handling higher screen resolutions better. (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: Bandwidth is the maximum amount of information (measured in MB per second) that can be moved over the external memory interface in a second. It is worked out by multiplying the interface width by the speed of its memory. In the case of DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly write to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the the card's clock speed. 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 also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
