Radeon RX 6600 vs Radeon VII

Intro

Compare those specifications to the Radeon VII, which makes use of a 7 nm design. AMD has clocked the core frequency at 1400 MHz. The HBM2 RAM is set to run at a speed of 1000 MHz on this specific model. It features 3840 SPUs as well as 240 Texture Address Units and 64 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 6600		132 Watts
Radeon VII		295 Watts
	Difference: 163 Watts (123%)

Memory Bandwidth

Theoretically speaking, the Radeon VII is 357% faster than the Radeon RX 6600 overall, because of its higher data rate. (explain)

Radeon VII		1048576 MB/sec
Radeon RX 6600		229376 MB/sec
	Difference: 819200 (357%)

Texel Rate

The Radeon VII will be quite a bit (about 85%) faster with regards to AF than the Radeon RX 6600. (explain)

Radeon VII		336000 Mtexels/sec
Radeon RX 6600		182112 Mtexels/sec
	Difference: 153888 (85%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon RX 6600 is the winner, though not by far. (explain)

Radeon RX 6600		104064 Mpixels/sec
Radeon VII		89600 Mpixels/sec
	Difference: 14464 (16%)

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 information (in units of MB per second) that can be transferred past the external memory interface in a second. It's worked out by multiplying the card's interface width by its memory clock speed. In the case of DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This is calculated by multiplying the total texture units by the core 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 applied per second.

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