Geforce GTX 680 vs Radeon RX 6600

Intro

Compare all that to the Radeon RX 6600, which features GPU core speed of 1626 MHz, and 8192 MB of GDDR6 memory running at 1750 MHz through a 128-bit bus. It also features 1792 Stream Processors, 112 TAUs, and 64 ROPs.

Texel Rate

The Radeon RX 6600 is much (about 41%) better at texture filtering than the Geforce GTX 680. (explain)

Radeon RX 6600		182112 Mtexels/sec
Geforce GTX 680		128768 Mtexels/sec
	Difference: 53344 (41%)

Pixel Rate

The Radeon RX 6600 will be quite a bit (more or less 223%) better at FSAA than the Geforce GTX 680, and capable of handling higher screen resolutions without losing too much performance. (explain)

Radeon RX 6600		104064 Mpixels/sec
Geforce GTX 680		32192 Mpixels/sec
	Difference: 71872 (223%)

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: Bandwidth is the max amount of information (counted in MB per second) that can be transported across the external memory interface in a second. It is worked out by multiplying the card's interface width by the speed of its memory. If the card has DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends 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.
