GeForce GTX 580 vs Radeon RX 6600

Intro

Compare that to the Radeon RX 6600, which has a core clock speed of 1626 MHz and a GDDR6 memory frequency of 1750 MHz. It also makes use of a 128-bit memory bus, and makes use of a 7 nm design. It is made up of 1792 SPUs, 112 TAUs, and 64 Raster Operation Units.

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

Memory Bandwidth

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

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

Texel Rate

The Radeon RX 6600 is quite a bit (more or less 269%) faster with regards to anisotropic 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 running with high levels of AA is important to you, then the Radeon RX 6600 is superior to the GeForce GTX 580, 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 maximum amount of information (measured in megabytes per second) that can be transferred across the external memory interface within a second. It's worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's 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 amount of texture map elements (texels) that can be processed per second. This figure is calculated by multiplying the total texture units by the core speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate 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 drawing the pixels (image) on 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 bandwidth is, the lower the potential to reach the maximum fill rate.
