Geforce GTX 680 vs Radeon RX 6600

Intro

Compare all of that to the Radeon RX 6600, which has a clock frequency of 1626 MHz and a GDDR6 memory frequency of 1750 MHz. It also features a 128-bit bus, and makes use of a 7 nm design. It is made up of 1792 SPUs, 112 TAUs, 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 a little 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 (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

If running with high levels of AA is important to you, then the Radeon RX 6600 is a better choice, 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: Bandwidth is the max amount of information (in units of megabytes per second) that can be transported past the external memory interface in one second. The number is calculated by multiplying the bus width by the speed of its memory. If the card has DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
