GeForce GTX 580 3GB vs Radeon RX 6600

Intro

Compare all that to the Radeon RX 6600, which comes with a clock frequency of 1626 MHz and a GDDR6 memory frequency of 1750 MHz. It also features a 128-bit memory bus, and makes use of a 7 nm design. It is comprised of 1792 SPUs, 112 Texture Address Units, and 64 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 6600		132 Watts
GeForce GTX 580 3GB		244 Watts
	Difference: 112 Watts (85%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 6600 should perform just a bit faster than the GeForce GTX 580 3GB in general. (explain)

Radeon RX 6600		229376 MB/sec
GeForce GTX 580 3GB		192384 MB/sec
	Difference: 36992 (19%)

Texel Rate

The Radeon RX 6600 should be quite a bit (approximately 269%) faster with regards to texture filtering than the GeForce GTX 580 3GB. (explain)

Radeon RX 6600		182112 Mtexels/sec
GeForce GTX 580 3GB		49408 Mtexels/sec
	Difference: 132704 (269%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon RX 6600 is the winner, and very much so. (explain)

Radeon RX 6600		104064 Mpixels/sec
GeForce GTX 580 3GB		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 maximum amount of data (in units of MB per second) that can be transferred across the external memory interface in a second. It is worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
