Radeon RX 6600 XT vs Radeon VII

Intro

Compare that to the Radeon VII, which features core speeds of 1400 MHz on the GPU, and 1000 MHz on the 16384 MB of HBM2 memory. It features 3840 SPUs as well as 240 Texture Address Units and 64 ROPs.

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 theoretically be a lot better than the Radeon RX 6600 XT in general. (explain)

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

Texel Rate

The Radeon VII should be much (more or less 33%) better at AF 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 a better choice, 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: Memory bandwidth is the largest amount of information (in units of megabytes per second) that can be transferred over the external memory interface in one second. It is worked out by multiplying the bus width by the speed of its memory. In the case of DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This number is worked out by multiplying the total amount of texture units 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 processed in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the clock 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 output rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
