GeForce GTX 580 vs Radeon RX 6600

Intro

Compare that to the Radeon RX 6600, which comes with a clock speed of 1626 MHz and a GDDR6 memory frequency of 1750 MHz. It also uses a 128-bit memory bus, and uses a 7 nm design. It is made up of 1792 SPUs, 112 TAUs, and 64 ROPs.

GeForce GTX 580		192384 MB/sec
	Difference: 36992 (19%)

Texel Rate

The Radeon RX 6600 should be quite a bit (about 269%) faster with regards to texture filtering than the GeForce GTX 580. (explain)

Radeon RX 6600		182112 Mtexels/sec
GeForce GTX 580		49408 Mtexels/sec
	Difference: 132704 (269%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon RX 6600 is a better choice, by a large margin. (explain)

Radeon RX 6600		104064 Mpixels/sec
GeForce GTX 580		37056 Mpixels/sec
	Difference: 67008 (181%)

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 MB per second) that can be transported past the external memory interface within a second. It's calculated by multiplying the interface width by the speed of its memory. In the case of DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one 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 card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the clock speed of the card. 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 is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
