Radeon RX 6600 XT vs Radeon VII

Intro

Compare those specifications to the Radeon VII, which features a core clock frequency of 1400 MHz and a HBM2 memory frequency of 1000 MHz. It also uses a 4096-bit bus, and makes use of a 7 nm design. It features 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 in theory 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 is much (about 33%) faster with regards to 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

The Radeon RX 6600 XT should be quite a bit (approximately 41%) faster with regards to full screen anti-aliasing than the Radeon VII, and also able to handle higher resolutions without losing too much performance. (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 largest amount of data (counted in MB per second) that can be moved across the external memory interface within a second. It is worked out by multiplying the bus width by the speed of its memory. In the case of DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, 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 texture map elements (texels) that are processed per 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 per second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the the core 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 quite a few 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.
