Radeon RX 590 vs Radeon RX 6600

Intro

Compare all that to the Radeon RX 6600, which has a clock frequency of 1626 MHz and a GDDR6 memory speed of 1750 MHz. It also uses a 128-bit bus, and makes use of a 7 nm design. It is made up of 1792 SPUs, 112 TAUs, and 64 Raster Operation Units.

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

Texel Rate

The Radeon RX 590 should be a bit (about 16%) more effective at anisotropic filtering than the Radeon RX 6600. (explain)

Radeon RX 590		211536 Mtexels/sec
Radeon RX 6600		182112 Mtexels/sec
	Difference: 29424 (16%)

Pixel Rate

The Radeon RX 6600 will be a lot (more or less 121%) better at AA than the Radeon RX 590, and should be capable of handling higher screen resolutions without losing too much performance. (explain)

Radeon RX 6600		104064 Mpixels/sec
Radeon RX 590		47008 Mpixels/sec
	Difference: 57056 (121%)

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 maximum amount of information (counted in megabytes per second) that can be transported past the external memory interface in one second. The number is worked out by multiplying the interface width by the speed of its memory. In the case of DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, 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 number of texture map elements (texels) that can be processed in one second. This is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly write to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
