GeForce GTX 960 vs Radeon R9 M385X

Intro

Compare those specs to the Radeon R9 M385X, which has a core clock frequency of 1100 MHz and a GDDR5 memory frequency of 1500 MHz. It also uses a 128-bit memory bus, and uses a 28 nm design. It is made up of 896 SPUs, 56 TAUs, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the GeForce GTX 960 should in theory be a small bit superior to the Radeon R9 M385X overall. (explain)

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

Texel Rate

The GeForce GTX 960 should be just a bit (approximately 17%) more effective 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 screen 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: Bandwidth is the max amount of data (measured in megabytes per second) that can be moved across the external memory interface in a second. It's calculated by multiplying the bus width by the speed of its memory. If it uses DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better 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 number of texture map elements (texels) that can be processed in one second. This figure is worked out by multiplying the total texture units of the card by the core speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly record to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes 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 maximum fill rate.
