Geforce GTX 680 vs Radeon RX 6600

Intro

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

Radeon RX 6600		132 Watts
Geforce GTX 680		195 Watts
	Difference: 63 Watts (48%)

Memory Bandwidth

As far as performance goes, the Radeon RX 6600 should in theory be a bit superior to the Geforce GTX 680 in general. (explain)

Radeon RX 6600		229376 MB/sec
Geforce GTX 680		192256 MB/sec
	Difference: 37120 (19%)

Texel Rate

The Radeon RX 6600 is quite a bit (more or less 41%) more effective at anisotropic 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 should be much (approximately 223%) better at AA than the Geforce GTX 680, and also able to handle higher screen resolutions more effectively. (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: Memory bandwidth is the maximum amount of information (counted in MB per second) that can be transferred past the external memory interface in a second. It is worked out by multiplying the bus width by its memory clock speed. If the card has DDR type memory, it 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 anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka 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, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
