GeForce GTX 960 vs Radeon R9 M385X

Intro

Compare all that to the Radeon R9 M385X, which has GPU core speed of 1100 MHz, and 4096 MB of GDDR5 RAM set to run at 1500 MHz through a 128-bit bus. It also is comprised of 896 SPUs, 56 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce GTX 960 is 17% quicker than the Radeon R9 M385X in general, because of its higher bandwidth. (explain)

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

Texel Rate

The GeForce GTX 960 should be a little bit (approximately 17%) better at AF than the Radeon R9 M385X. (explain)

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

Pixel Rate

The GeForce GTX 960 should be much (approximately 105%) faster with regards to AA than the Radeon R9 M385X, and will be able to handle higher screen resolutions without slowing down too much. (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 information (measured in megabytes per second) that can be transferred over the external memory interface in a second. The number is worked out by multiplying the interface width by its memory speed. If the card has DDR RAM, it should 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 anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number 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 fill rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
