GeForce GTX 750 Ti vs Radeon R9 M380

Intro

Compare those specs to the Radeon R9 M380, which features a GPU core clock speed of 1000 MHz, and 4096 MB of GDDR5 memory set to run at 1500 MHz through a 128-bit bus. It also is made up of 640 SPUs, 40 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the Radeon R9 M380 should theoretically be a small bit superior to the GeForce GTX 750 Ti in general. (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 (about 2%) better at anisotropic 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 a high resolution is important to you, then the GeForce GTX 750 Ti is the winner, though only just barely. (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.

Specifications

Memory Bandwidth: Memory bandwidth is the largest amount of data (counted in MB per second) that can be transported across the external memory interface in a second. The number is calculated by multiplying the bus width by its memory speed. If the card has DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This is worked out by multiplying the total 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 texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
