Radeon RX 6600 XT vs Radeon RX 6700 XT

Intro

Compare those specs to the Radeon RX 6700 XT, which comes with clock speeds of 2321 MHz on the GPU, and 2000 MHz on the (Unknown) MB of GDDR6 memory. It features 2560 SPUs along with 160 Texture Address Units and 64 ROPs.

Radeon RX 6600 XT		262144 MB/sec
	Difference: 131072 (50%)

Texel Rate

The Radeon RX 6700 XT should be quite a bit (about 47%) faster with regards to AF than the Radeon RX 6600 XT. (explain)

Radeon RX 6700 XT		371360 Mtexels/sec
Radeon RX 6600 XT		251904 Mtexels/sec
	Difference: 119456 (47%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon RX 6700 XT is superior to the Radeon RX 6600 XT, but only just. (explain)

Radeon RX 6700 XT		148544 Mpixels/sec
Radeon RX 6600 XT		125952 Mpixels/sec
	Difference: 22592 (18%)

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 maximum amount of data (in units of MB per second) that can be transferred over the external memory interface in one second. It is calculated by multiplying the card's interface width by the speed of its memory. If the card has DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
