Radeon RX 6600 vs Radeon RX 6800

Intro

Compare all of that to the Radeon RX 6800, which makes use of a 7 nm design. AMD has clocked the core speed at 1700 MHz. The GDDR6 RAM is set to run at a speed of 2000 MHz on this specific card. It features 3840 SPUs as well as 240 Texture Address Units and 96 ROPs.

Radeon RX 6600		132 Watts
Radeon RX 6800		250 Watts
	Difference: 118 Watts (89%)

Memory Bandwidth

As far as performance goes, the Radeon RX 6800 should theoretically be much superior to the Radeon RX 6600 in general. (explain)

Radeon RX 6800		524288 MB/sec
Radeon RX 6600		229376 MB/sec
	Difference: 294912 (129%)

Texel Rate

The Radeon RX 6800 should be a lot (more or less 124%) better at anisotropic filtering than the Radeon RX 6600. (explain)

Radeon RX 6800		408000 Mtexels/sec
Radeon RX 6600		182112 Mtexels/sec
	Difference: 225888 (124%)

Pixel Rate

If running with a high screen resolution is important to you, then the Radeon RX 6800 is a better choice, by a large margin. (explain)

Radeon RX 6800		163200 Mpixels/sec
Radeon RX 6600		104064 Mpixels/sec
	Difference: 59136 (57%)

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 MB per second) that can be transported past the external memory interface within a second. It's worked out by multiplying the bus width by the speed of its memory. If it uses DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, 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 can be processed in one second. This is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at 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 the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the the core 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 rate is also dependant on quite a few 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.
