VS

Radeon RX 570 vs Radeon RX 6600

Intro

The Radeon RX 570 has a GPU core speed of 1168 MHz, and the 4096 MB of GDDR5 memory runs at 1750 MHz through a 256-bit bus. It also is made up of 2048 Stream Processors, 128 Texture Address Units, and 32 Raster Operation Units.

Compare those specifications to the Radeon RX 6600, which uses a 7 nm design. AMD has clocked the core frequency at 1626 MHz. The GDDR6 memory works at a frequency of 1750 MHz on this specific card. It features 1792 SPUs along with 112 TAUs and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 6600 132 Watts
Radeon RX 570 150 Watts
Difference: 18 Watts (14%)

Memory Bandwidth

Both cards have the exact same bandwidth, so in theory they should perform exactly the same. (explain)

Texel Rate

The Radeon RX 6600 will be quite a bit (about 22%) more effective at texture filtering than the Radeon RX 570. (explain)

Radeon RX 6600 182112 Mtexels/sec
Radeon RX 570 149504 Mtexels/sec
Difference: 32608 (22%)

Pixel Rate

The Radeon RX 6600 will be a lot (more or less 178%) faster with regards to full screen anti-aliasing than the Radeon RX 570, and also should be able to handle higher resolutions more effectively. (explain)

Radeon RX 6600 104064 Mpixels/sec
Radeon RX 570 37376 Mpixels/sec
Difference: 66688 (178%)

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.

Memory Bandwidth: Memory bandwidth is the largest amount of information (in units of megabytes per second) that can be transported across the external memory interface in one second. It's calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR type RAM, the result should be multiplied by 2 again. If 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 high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This is worked out by multiplying the total texture units 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 in a second.

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