Geforce GTX 770 vs Radeon RX 6600 XT

Intro

Compare all that to the Radeon RX 6600 XT, which has a core clock speed of 1968 MHz and a GDDR6 memory speed of 2000 MHz. It also makes use of a 128-bit bus, and makes use of a 7 nm design. It is made up of 2048 SPUs, 128 TAUs, and 64 Raster Operation Units.

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

Memory Bandwidth

In theory, the Radeon RX 6600 XT should perform a bit faster than the Geforce GTX 770 overall. (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 much (more or less 88%) faster with regards to 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

If running with high levels of AA is important to you, then the Radeon RX 6600 XT is a better choice, by far. (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 (measured in megabytes per second) that can be transferred across the external memory interface within a second. The number is worked out by multiplying the card's bus width by its memory speed. If it uses DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
