Radeon RX 6600 XT vs Radeon VII

Intro

Compare those specifications to the Radeon VII, which features GPU core speed of 1400 MHz, and 16384 MB of HBM2 memory set to run at 1000 MHz through a 4096-bit bus. It also is made up of 3840 SPUs, 240 Texture Address Units, and 64 Raster Operation 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

Performance-wise, the Radeon VII should theoretically be quite a bit superior to 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 will be quite a bit (more or less 33%) better at texture 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 running with lots of anti-aliasing 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: Bandwidth is the maximum amount of data (counted in megabytes per second) that can be moved past the external memory interface in one second. The number is calculated by multiplying the card's bus width by its memory speed. If it uses DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, 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 amount of texture map elements (texels) that are processed in one second. This figure is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The higher the texel rate, the better the graphics 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 most pixels the video card can possibly write to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill 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 reach the max fill rate.
