GeForce GTX 750 vs Radeon R9 M385X

Intro

Compare all that to the Radeon R9 M385X, which makes use of a 28 nm design. AMD has clocked the core frequency at 1100 MHz. The GDDR5 RAM runs at a speed of 1500 MHz on this model. It features 896 SPUs along with 56 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon R9 M385X should in theory perform a bit faster than the GeForce GTX 750 in general. (explain)

Radeon R9 M385X		96000 MB/sec
GeForce GTX 750		80000 MB/sec
	Difference: 16000 (20%)

Texel Rate

The Radeon R9 M385X is a lot (about 89%) more effective at anisotropic filtering than the GeForce GTX 750. (explain)

Radeon R9 M385X		61600 Mtexels/sec
GeForce GTX 750		32640 Mtexels/sec
	Difference: 28960 (89%)

Pixel Rate

The Radeon R9 M385X will be just a bit (about 8%) more effective at AA than the GeForce GTX 750, and also capable of handling higher resolutions without losing too much performance. (explain)

Radeon R9 M385X		17600 Mpixels/sec
GeForce GTX 750		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: Memory bandwidth is the largest amount of data (measured in MB per second) that can be transferred across the external memory interface within a second. It is calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This is calculated by multiplying the total number of texture units by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at 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 the video card can possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel 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 reach the maximum fill rate.
