Geforce GTX 760 vs Radeon R9 M385X

Intro

Compare all of that to the Radeon R9 M385X, which comes with a GPU core clock speed of 1100 MHz, and 4096 MB of GDDR5 memory running at 1500 MHz through a 128-bit bus. It also 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 Geforce GTX 760 is 100% faster than the Radeon R9 M385X overall, due to its higher bandwidth. (explain)

Geforce GTX 760		192256 MB/sec
Radeon R9 M385X		96000 MB/sec
	Difference: 96256 (100%)

Texel Rate

The Geforce GTX 760 is a lot (approximately 53%) faster with regards to texture filtering than the Radeon R9 M385X. (explain)

Geforce GTX 760		94080 Mtexels/sec
Radeon R9 M385X		61600 Mtexels/sec
	Difference: 32480 (53%)

Pixel Rate

The Geforce GTX 760 should be much (about 78%) faster with regards to AA than the Radeon R9 M385X, and also able to handle higher resolutions without slowing down too much. (explain)

Geforce GTX 760		31360 Mpixels/sec
Radeon R9 M385X		17600 Mpixels/sec
	Difference: 13760 (78%)

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 (in units of MB per second) that can be moved across the external memory interface in a second. It is worked out by multiplying the card's bus width by its memory speed. If the card has DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs 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 lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
