GeForce 8800 GT 512MB		105 Watts
Radeon RX 6600		132 Watts
	Difference: 27 Watts (26%)

Memory Bandwidth

As far as performance goes, the Radeon RX 6600 should in theory be a lot better than the GeForce 8800 GT 512MB in general. (explain)

Radeon RX 6600		229376 MB/sec
GeForce 8800 GT 512MB		57600 MB/sec
	Difference: 171776 (298%)

Texel Rate

The Radeon RX 6600 should be a lot (more or less 442%) faster with regards to AF than the GeForce 8800 GT 512MB. (explain)

Radeon RX 6600		182112 Mtexels/sec
GeForce 8800 GT 512MB		33600 Mtexels/sec
	Difference: 148512 (442%)

Pixel Rate

The Radeon RX 6600 will be quite a bit (approximately 984%) better at AA than the GeForce 8800 GT 512MB, and also should be capable of handling higher screen resolutions while still performing well. (explain)

Radeon RX 6600		104064 Mpixels/sec
GeForce 8800 GT 512MB		9600 Mpixels/sec
	Difference: 94464 (984%)

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 maximum 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 card's bus width by its memory speed. In the case of DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly write to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs 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 fill rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
