GeForce GTX 660 vs Radeon RX 5600 XT

Intro

Compare all that to the Radeon RX 5600 XT, which has a clock speed of 1375 MHz and a GDDR6 memory speed of 1500 MHz. It also features a 192-bit bus, and uses a 7 nm design. It is comprised of 2304 SPUs, 144 Texture Address Units, and 64 ROPs.

GeForce GTX 660		78400 Mtexels/sec
	Difference: 119600 (153%)

Pixel Rate

The Radeon RX 5600 XT is quite a bit (more or less 274%) more effective at FSAA than the GeForce GTX 660, and will be capable of handling higher screen resolutions better. (explain)

Radeon RX 5600 XT		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: Memory bandwidth is the maximum amount of data (in units of MB per second) that can be transported over the external memory interface within a second. It's worked out by multiplying the card's bus width by its memory clock speed. If the card has DDR RAM, it should be multiplied by 2 once again. If it uses 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 processed in one second. This number is calculated by multiplying the total texture units by the core 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 most pixels the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines 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 lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
