Radeon RX 570 vs Radeon RX 6600 XT

Intro

Compare those specifications to the Radeon RX 6600 XT, which comes with core clock speeds of 1968 MHz on the GPU, and 2000 MHz on the 8192 MB of GDDR6 memory. It features 2048 SPUs as well as 128 TAUs and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 570		150 Watts
Radeon RX 6600 XT		160 Watts
	Difference: 10 Watts (7%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 6600 XT should be just a bit faster than the Radeon RX 570 overall. (explain)

Radeon RX 6600 XT		262144 MB/sec
Radeon RX 570		229376 MB/sec
	Difference: 32768 (14%)

Texel Rate

The Radeon RX 6600 XT is quite a bit (more or less 68%) better at anisotropic filtering than the Radeon RX 570. (explain)

Radeon RX 6600 XT		251904 Mtexels/sec
Radeon RX 570		149504 Mtexels/sec
	Difference: 102400 (68%)

Pixel Rate

The Radeon RX 6600 XT will be quite a bit (about 237%) more effective at FSAA than the Radeon RX 570, and also will be capable of handling higher resolutions without losing too much performance. (explain)

Radeon RX 6600 XT		125952 Mpixels/sec
Radeon RX 570		37376 Mpixels/sec
	Difference: 88576 (237%)

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: Memory bandwidth is the largest amount of information (in units of megabytes per second) that can be transported over the external memory interface in a second. The number is calculated by multiplying the interface width by its memory speed. In the case of DDR memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster 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 applied per second. This number is worked out by multiplying the total texture units by the core speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
