GeForce GTX 1060 3GB vs Radeon R9 M395X

Intro

Compare all that to the Radeon R9 M395X, which comes with core speeds of 723 MHz on the GPU, and 1250 MHz on the 4096 MB of GDDR5 memory. It features 2048 SPUs as well as 128 Texture Address Units and 32 ROPs.

GeForce GTX 1060 3GB		196608 MB/sec
Radeon R9 M395X		160000 MB/sec
	Difference: 36608 (23%)

Texel Rate

The GeForce GTX 1060 3GB should be a small bit (more or less 17%) more effective at texture filtering than the Radeon R9 M395X. (explain)

GeForce GTX 1060 3GB		108432 Mtexels/sec
Radeon R9 M395X		92544 Mtexels/sec
	Difference: 15888 (17%)

Pixel Rate

The GeForce GTX 1060 3GB will be quite a bit (approximately 212%) more effective at AA than the Radeon R9 M395X, and also will be capable of handling higher screen resolutions without losing too much performance. (explain)

GeForce GTX 1060 3GB		72288 Mpixels/sec
Radeon R9 M395X		23136 Mpixels/sec
	Difference: 49152 (212%)

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 information (counted in megabytes per second) that can be moved across the external memory interface in one second. It's calculated by multiplying the card's interface width by the speed of its memory. If the card has DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to the local memory in a second - measured in millions of pixels per second. The figure 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 filling the screen with pixels (the image). The actual pixel fill 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.
