GeForce GTX 660 vs Radeon RX 5500 XT

Intro

Compare those specs to the Radeon RX 5500 XT, which makes use of a 7 nm design. AMD has set the core frequency at 1717 MHz. The GDDR6 memory works at a frequency of 1750 MHz on this card. It features 1408 SPUs as well as 88 TAUs and 32 ROPs.

Radeon RX 5500 XT		151096 Mtexels/sec
GeForce GTX 660		78400 Mtexels/sec
	Difference: 72696 (93%)

Pixel Rate

The Radeon RX 5500 XT will be quite a bit (approximately 134%) faster with regards to full screen anti-aliasing than the GeForce GTX 660, and also should be capable of handling higher resolutions while still performing well. (explain)

Radeon RX 5500 XT		54944 Mpixels/sec
GeForce GTX 660		23520 Mpixels/sec
	Difference: 31424 (134%)

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 (counted in megabytes per second) that can be transported across the external memory interface in one second. It is calculated by multiplying the card's bus width by its memory speed. If it uses DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total number of texture units by the core speed of the chip. The higher this number, the better the video 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 the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
