Radeon RX 5500 XT vs Radeon RX 6600

Intro

Compare all of that to the Radeon RX 6600, which uses a 7 nm design. AMD has set the core speed at 1626 MHz. The GDDR6 RAM works at a speed of 1750 MHz on this particular card. It features 1792 SPUs as well as 112 TAUs and 64 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 5500 XT		130 Watts
Radeon RX 6600		132 Watts
	Difference: 2 Watts (2%)

Memory Bandwidth

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

Texel Rate

The Radeon RX 6600 should be much (more or less 21%) more effective at AF than the Radeon RX 5500 XT. (explain)

Radeon RX 6600		182112 Mtexels/sec
Radeon RX 5500 XT		151096 Mtexels/sec
	Difference: 31016 (21%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon RX 6600 is superior to the Radeon RX 5500 XT, and very much so. (explain)

Radeon RX 6600		104064 Mpixels/sec
Radeon RX 5500 XT		54944 Mpixels/sec
	Difference: 49120 (89%)

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 maximum amount of information (in units of MB per second) that can be transported across the external memory interface in a second. It is calculated by multiplying the bus width by the speed of its memory. If it uses DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly record to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
