Geforce GTX 770 vs Radeon RX 6600 XT

Intro

Compare those specs to the Radeon RX 6600 XT, which features GPU clock speed of 1968 MHz, and 8192 MB of GDDR6 RAM set to run at 2000 MHz through a 128-bit bus. It also is made up of 2048 Stream Processors, 128 Texture Address Units, 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

Theoretically speaking, the Radeon RX 6600 XT should be 17% faster than the Geforce GTX 770 in general, due to its higher bandwidth. (explain)

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

Texel Rate

The Radeon RX 6600 XT will be a lot (more or less 88%) more effective at AF than the Geforce GTX 770. (explain)

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

Pixel Rate

The Radeon RX 6600 XT is quite a bit (about 276%) faster with regards to FSAA than the Geforce GTX 770, and also will be able to handle higher screen resolutions better. (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 max amount of information (in units of MB per second) that can be transferred past the external memory interface in one second. It is worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied 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 video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
