GeForce GTX 750 Ti vs Radeon R9 M380

Intro

Compare those specs to the Radeon R9 M380, which comes with a core clock speed of 1000 MHz and a GDDR5 memory frequency of 1500 MHz. It also makes use of a 128-bit memory bus, and uses a 28 nm design. It is made up of 640 SPUs, 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, because of its higher 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%) faster with regards to 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 a high resolution is important to you, then the GeForce GTX 750 Ti is superior to the Radeon R9 M380, but 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.

Specifications

Memory Bandwidth: Bandwidth is the largest amount of data (counted in megabytes per second) that can be transported across the external memory interface within a second. It is calculated by multiplying the interface width by the speed of its memory. If it uses DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. 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 texture map elements (texels) that are applied in one second. This number is worked out by multiplying the total number of texture units by the core speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
