Geforce GTX 680 vs Radeon RX 6600

Intro

Compare all that to the Radeon RX 6600, which comes with core speeds of 1626 MHz on the GPU, and 1750 MHz on the 8192 MB of GDDR6 RAM. It features 1792 SPUs along with 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 should in theory 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 is quite a bit (more or less 41%) more effective at AF 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 a high resolution is important to you, then the Radeon RX 6600 is superior to the Geforce GTX 680, and very much so. (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 max amount of data (measured in MB per second) that can be transferred past the external memory interface in a second. The number is calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better 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 can be processed per second. This figure is worked out by multiplying the total texture units by the core clock 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 applied in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines 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 rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
