Radeon RX 6600 XT vs Radeon VII

Intro

Compare those specs to the Radeon VII, which uses a 7 nm design. AMD has clocked the core speed at 1400 MHz. The HBM2 memory runs at a speed of 1000 MHz on this particular card. It features 3840 SPUs as well as 240 TAUs and 64 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 6600 XT		160 Watts
Radeon VII		295 Watts
	Difference: 135 Watts (84%)

Memory Bandwidth

As far as performance goes, the Radeon VII should in theory be much better than the Radeon RX 6600 XT overall. (explain)

Radeon VII		1048576 MB/sec
Radeon RX 6600 XT		262144 MB/sec
	Difference: 786432 (300%)

Texel Rate

The Radeon VII is much (about 33%) better at anisotropic filtering than the Radeon RX 6600 XT. (explain)

Radeon VII		336000 Mtexels/sec
Radeon RX 6600 XT		251904 Mtexels/sec
	Difference: 84096 (33%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon RX 6600 XT is superior to the Radeon VII, by a large margin. (explain)

Radeon RX 6600 XT		125952 Mpixels/sec
Radeon VII		89600 Mpixels/sec
	Difference: 36352 (41%)

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 information (counted in MB per second) that can be moved past the external memory interface in one second. It's worked out by multiplying the interface width by the speed of its memory. In the case of DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better 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 are applied in one second. This is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
