Geforce GTX 680 vs Radeon RX 6600

Intro

Compare all of that to the Radeon RX 6600, which comes with GPU core speed of 1626 MHz, and 8192 MB of GDDR6 RAM running at 1750 MHz through a 128-bit bus. It also features 1792 SPUs, 112 Texture Address Units, and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

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

Memory Bandwidth

The Radeon RX 6600, in theory, should perform just a bit faster than the Geforce GTX 680 overall. (explain)

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

Texel Rate

The Radeon RX 6600 should be a lot (approximately 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

If running with lots of anti-aliasing is important to you, then the Radeon RX 6600 is the winner, by far. (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 largest amount of information (in units of MB per second) that can be moved across the external memory interface in a second. The number is worked out by multiplying the card's bus width by its memory speed. If it uses DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
