Radeon RX 6600 vs Radeon RX Vega 56

Intro

Compare those specs to the Radeon RX Vega 56, which features core speeds of 1156 MHz on the GPU, and 1600 MHz on the 8192 MB of HBM2 memory. It features 3584 SPUs along with 224 TAUs and 64 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 6600		132 Watts
Radeon RX Vega 56		210 Watts
	Difference: 78 Watts (59%)

Memory Bandwidth

Theoretically speaking, the Radeon RX Vega 56 is 83% quicker than the Radeon RX 6600 in general, because of its greater data rate. (explain)

Radeon RX Vega 56		419430 MB/sec
Radeon RX 6600		229376 MB/sec
	Difference: 190054 (83%)

Texel Rate

The Radeon RX Vega 56 should be quite a bit (more or less 42%) better at anisotropic filtering than the Radeon RX 6600. (explain)

Radeon RX Vega 56		258944 Mtexels/sec
Radeon RX 6600		182112 Mtexels/sec
	Difference: 76832 (42%)

Pixel Rate

The Radeon RX 6600 is much (more or less 41%) more effective at anti-aliasing than the Radeon RX Vega 56, and should be able to handle higher screen resolutions more effectively. (explain)

Radeon RX 6600		104064 Mpixels/sec
Radeon RX Vega 56		73984 Mpixels/sec
	Difference: 30080 (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 megabytes per second) that can be transported across the external memory interface in a second. It is calculated by multiplying the card's bus width by its memory speed. If it uses DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This figure is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
