GeForce GTX 580 3GB vs Radeon RX 6600

Intro

Compare all of that to the Radeon RX 6600, which features a core clock frequency of 1626 MHz and a GDDR6 memory speed 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 Texture Address Units, and 64 ROPs.

	Difference: 36992 (19%)

Texel Rate

The Radeon RX 6600 will be quite a bit (more or less 269%) faster with regards to anisotropic 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 a high resolution 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 megabytes per second) that can be moved across the external memory interface in one second. It is worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster 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 number of texture map elements (texels) that can be applied per second. This is worked out by multiplying the total texture units of the card by the core speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to 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 get to the max fill rate.
