GeForce GTX 750 Ti vs Radeon R9 M385X

Intro

Compare all of that to the Radeon R9 M385X, which has a core clock speed of 1100 MHz and a GDDR5 memory speed of 1500 MHz. It also features a 128-bit memory bus, and makes use of a 28 nm design. It is made up of 896 SPUs, 56 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R9 M385X should be a bit faster than the GeForce GTX 750 Ti overall. (explain)

Radeon R9 M385X		96000 MB/sec
GeForce GTX 750 Ti		86400 MB/sec
	Difference: 9600 (11%)

Texel Rate

The Radeon R9 M385X is quite a bit (about 51%) more effective at anisotropic filtering than the GeForce GTX 750 Ti. (explain)

Radeon R9 M385X		61600 Mtexels/sec
GeForce GTX 750 Ti		40800 Mtexels/sec
	Difference: 20800 (51%)

Pixel Rate

The Radeon R9 M385X will be a bit (approximately 8%) better at anti-aliasing than the GeForce GTX 750 Ti, and should be capable of handling higher resolutions better. (explain)

Radeon R9 M385X		17600 Mpixels/sec
GeForce GTX 750 Ti		16320 Mpixels/sec
	Difference: 1280 (8%)

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 (in units of megabytes per second) that can be transferred past the external memory interface in a second. It's worked out by multiplying the bus width by its memory clock speed. In the case of DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate 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 filling the screen with pixels (the image). The actual pixel output rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
