GeForce GTX 580 vs Radeon RX 6600

Intro

Compare that to the Radeon RX 6600, which has a GPU core clock speed of 1626 MHz, and 8192 MB of GDDR6 RAM set to run at 1750 MHz through a 128-bit bus. It also is comprised of 1792 Stream Processors, 112 Texture Address Units, and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

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

Memory Bandwidth

In theory, the Radeon RX 6600 should be 19% quicker than the GeForce GTX 580 in general, due to its higher bandwidth. (explain)

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

Texel Rate

The Radeon RX 6600 will be much (more or less 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 running with high levels of AA is important to you, then the Radeon RX 6600 is a better choice, and very much so. (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 megabytes per second) that can be moved past the external memory interface within a second. The number is worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR type RAM, it must 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 AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This is calculated by multiplying the total amount of texture units by the core speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly record to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the the card's clock speed. 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 rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
