GeForce GTX 750 Ti vs Radeon R9 M380

Intro

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

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the Radeon R9 M380 should in theory be a little 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 is a bit (more or less 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 using high levels of AA is important to you, then the GeForce GTX 750 Ti is superior to the Radeon R9 M380, but it probably won't make a huge difference. (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: Bandwidth is the max amount of information (in units of MB per second) that can be transferred across the external memory interface in a second. It's worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This number is calculated by multiplying the total texture units by the core clock 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 per second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends 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 max fill rate.
