Geforce GTX 670 vs Radeon RX 6600 XT

Intro

Compare that to the Radeon RX 6600 XT, which has GPU core speed of 1968 MHz, and 8192 MB of GDDR6 RAM running 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 670		170 Watts
	Difference: 10 Watts (6%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 6600 XT is 37% faster than the Geforce GTX 670 overall, because of its higher data rate. (explain)

Radeon RX 6600 XT		262144 MB/sec
Geforce GTX 670		192000 MB/sec
	Difference: 70144 (37%)

Texel Rate

The Radeon RX 6600 XT is much (more or less 146%) faster with regards to AF than the Geforce GTX 670. (explain)

Radeon RX 6600 XT		251904 Mtexels/sec
Geforce GTX 670		102480 Mtexels/sec
	Difference: 149424 (146%)

Pixel Rate

The Radeon RX 6600 XT should be a lot (about 330%) more effective at full screen anti-aliasing than the Geforce GTX 670, and also will be capable of handling higher resolutions while still performing well. (explain)

Radeon RX 6600 XT		125952 Mpixels/sec
Geforce GTX 670		29280 Mpixels/sec
	Difference: 96672 (330%)

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 (measured in MB per second) that can be transferred over the external memory interface in one second. The number is worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the card will be at 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 that the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
