GeForce GTX 660 vs Radeon RX 5600

Intro

Compare those specifications to the Radeon RX 5600, which features core clock speeds of 1375 MHz on the GPU, and 1500 MHz on the 6144 MB of GDDR6 RAM. It features 2048 SPUs along with 128 Texture Address Units and 64 ROPs.

GeForce GTX 660		140 Watts
Radeon RX 5600		150 Watts
	Difference: 10 Watts (7%)

Memory Bandwidth

The Radeon RX 5600, in theory, should be a lot faster than the GeForce GTX 660 in general. (explain)

Radeon RX 5600		294912 MB/sec
GeForce GTX 660		144192 MB/sec
	Difference: 150720 (105%)

Texel Rate

The Radeon RX 5600 is quite a bit (more or less 124%) better at texture filtering than the GeForce GTX 660. (explain)

Radeon RX 5600		176000 Mtexels/sec
GeForce GTX 660		78400 Mtexels/sec
	Difference: 97600 (124%)

Pixel Rate

If running with a high screen resolution is important to you, then the Radeon RX 5600 is the winner, by a large margin. (explain)

Radeon RX 5600		88000 Mpixels/sec
GeForce GTX 660		23520 Mpixels/sec
	Difference: 64480 (274%)

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 megabytes per second) that can be moved past the external memory interface within a second. It's worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
