GeForce GTX 580 vs Radeon RX 6600

Intro

The GeForce GTX 580 uses a 40 nm design. nVidia has clocked the core frequency at 772 MHz. The GDDR5 RAM works at a frequency of 1002 MHz on this particular model. It features 512 SPUs as well as 64 Texture Address Units and 48 ROPs.

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

GeForce GTX 580 49408 Mtexels/sec
Difference: 132704 (269%)

Pixel Rate

The Radeon RX 6600 will be a lot (about 181%) better at anti-aliasing than the GeForce GTX 580, and also will be able to handle higher screen resolutions while still performing well. (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.

Memory Bandwidth: Memory bandwidth is the maximum amount of data (measured in megabytes per second) that can be moved across the external memory interface within a second. It's calculated by multiplying the interface width by the speed of its memory. If it uses DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, 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 number of texture map elements (texels) that are applied in one second. This is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
