Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 6600		132 Watts
Geforce GTX 780		250 Watts
	Difference: 118 Watts (89%)

Memory Bandwidth

The Geforce GTX 780 should in theory perform much faster than the Radeon RX 6600 in general. (explain)

Geforce GTX 780		288384 MB/sec
Radeon RX 6600		229376 MB/sec
	Difference: 59008 (26%)

Texel Rate

The Radeon RX 6600 should be a bit (about 10%) faster with regards to anisotropic filtering than the Geforce GTX 780. (explain)

Radeon RX 6600		182112 Mtexels/sec
Geforce GTX 780		165696 Mtexels/sec
	Difference: 16416 (10%)

Pixel Rate

The Radeon RX 6600 is a lot (approximately 151%) more effective at anti-aliasing than the Geforce GTX 780, and also will be capable of handling higher screen resolutions without losing too much performance. (explain)

Radeon RX 6600		104064 Mpixels/sec
Geforce GTX 780		41424 Mpixels/sec
	Difference: 62640 (151%)

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 data (in units of MB per second) that can be transported past the external memory interface in one second. The number is worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better 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 number of texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total number of texture units by the core speed of the chip. The better 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 a second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. The number is worked out 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 filling the screen with pixels (the image). The actual pixel rate also depends on many 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.
