Radeon RX 5500 vs Radeon RX 6600

Intro

Compare those specifications to the Radeon RX 6600, which makes use of a 7 nm design. AMD has clocked the core speed at 1626 MHz. The GDDR6 memory runs at a frequency of 1750 MHz on this particular card. It features 1792 SPUs as well as 112 Texture Address Units and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 6600		132 Watts
Radeon RX 5500		150 Watts
	Difference: 18 Watts (14%)

Memory Bandwidth

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

Texel Rate

The Radeon RX 6600 is a lot (approximately 24%) faster with regards to AF than the Radeon RX 5500. (explain)

Radeon RX 6600		182112 Mtexels/sec
Radeon RX 5500		146960 Mtexels/sec
	Difference: 35152 (24%)

Pixel Rate

The Radeon RX 6600 will be a lot (about 95%) more effective at anti-aliasing than the Radeon RX 5500, and capable of handling higher screen resolutions more effectively. (explain)

Radeon RX 6600		104064 Mpixels/sec
Radeon RX 5500		53440 Mpixels/sec
	Difference: 50624 (95%)

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 largest amount of information (in units of megabytes per second) that can be transported across the external memory interface in a second. It's worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This number is calculated by multiplying the total amount of texture units of the card by the core 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 in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
