GeForce GTX 750 vs Radeon R9 M380

Intro

Compare those specifications to the Radeon R9 M380, which makes use of a 28 nm design. AMD has clocked the core speed at 1000 MHz. The GDDR5 RAM is set to run at a speed of 1500 MHz on this card. It features 640 SPUs along with 40 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R9 M380 is 20% quicker than the GeForce GTX 750 overall, because of its greater data rate. (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 (approximately 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 a better choice, 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.

Specifications

Memory Bandwidth: Bandwidth is the maximum amount of data (in units of megabytes per second) that can be moved across the external memory interface in one second. The number is calculated by multiplying the bus width by its memory speed. In the case of DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This figure 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 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 could possibly record to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
