GeForce GTX 960 vs Radeon R9 M385X

Intro

Compare those specs to the Radeon R9 M385X, which has a clock speed of 1100 MHz and a GDDR5 memory frequency of 1500 MHz. It also uses a 128-bit memory bus, and makes use of a 28 nm design. It is comprised of 896 SPUs, 56 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically, the GeForce GTX 960 should be just a bit faster than the Radeon R9 M385X in general. (explain)

GeForce GTX 960		112000 MB/sec
Radeon R9 M385X		96000 MB/sec
	Difference: 16000 (17%)

Texel Rate

The GeForce GTX 960 will be a bit (about 17%) better at anisotropic filtering than the Radeon R9 M385X. (explain)

GeForce GTX 960		72128 Mtexels/sec
Radeon R9 M385X		61600 Mtexels/sec
	Difference: 10528 (17%)

Pixel Rate

If using a high resolution is important to you, then the GeForce GTX 960 is superior to the Radeon R9 M385X, and very much so. (explain)

GeForce GTX 960		36064 Mpixels/sec
Radeon R9 M385X		17600 Mpixels/sec
	Difference: 18464 (105%)

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 maximum amount of data (counted in MB per second) that can be moved over the external memory interface in one second. It is calculated by multiplying the interface width by the speed of its memory. If the card has DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, 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 amount of texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total number of texture units by the core speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
