Geforce GTX 770 vs Radeon RX 6600 XT

Intro

Compare those specs to the Radeon RX 6600 XT, which has GPU clock speed of 1968 MHz, and 8192 MB of GDDR6 RAM running at 2000 MHz through a 128-bit bus. It also is comprised of 2048 SPUs, 128 TAUs, and 64 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 6600 XT		160 Watts
Geforce GTX 770		230 Watts
	Difference: 70 Watts (44%)

Memory Bandwidth

As far as performance goes, the Radeon RX 6600 XT should theoretically be a little bit better than the Geforce GTX 770 in general. (explain)

Radeon RX 6600 XT		262144 MB/sec
Geforce GTX 770		224384 MB/sec
	Difference: 37760 (17%)

Texel Rate

The Radeon RX 6600 XT is quite a bit (more or less 88%) more effective at texture filtering than the Geforce GTX 770. (explain)

Radeon RX 6600 XT		251904 Mtexels/sec
Geforce GTX 770		133888 Mtexels/sec
	Difference: 118016 (88%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon RX 6600 XT is superior to the Geforce GTX 770, and very much so. (explain)

Radeon RX 6600 XT		125952 Mpixels/sec
Geforce GTX 770		33472 Mpixels/sec
	Difference: 92480 (276%)

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 largest amount of data (in units of megabytes per second) that can be transported across the external memory interface within a second. It's worked out by multiplying the bus width by its memory clock speed. If it uses DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The better this number, the better the 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 amount of pixels the video card can possibly write to the local memory per second - measured in millions of pixels per second. The figure is calculated 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 output rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
