Radeon RX 6500 XT vs Radeon RX 6600

Intro

Compare those specs to the Radeon RX 6600, which makes use of a 7 nm design. AMD has clocked the core speed at 1626 MHz. The GDDR6 RAM works at a speed of 1750 MHz on this specific card. It features 1792 SPUs along with 112 Texture Address Units and 64 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 6500 XT		107 Watts
Radeon RX 6600		132 Watts
	Difference: 25 Watts (23%)

Memory Bandwidth

In theory, the Radeon RX 6600 should be 56% quicker than the Radeon RX 6500 XT overall, due to its higher bandwidth. (explain)

Radeon RX 6600		229376 MB/sec
Radeon RX 6500 XT		147456 MB/sec
	Difference: 81920 (56%)

Texel Rate

The Radeon RX 6600 will be quite a bit (more or less 29%) faster with regards to texture filtering than the Radeon RX 6500 XT. (explain)

Radeon RX 6600		182112 Mtexels/sec
Radeon RX 6500 XT		140800 Mtexels/sec
	Difference: 41312 (29%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon RX 6600 is the winner, by a large margin. (explain)

Radeon RX 6600		104064 Mpixels/sec
Radeon RX 6500 XT		70400 Mpixels/sec
	Difference: 33664 (48%)

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 data (measured in megabytes per second) that can be moved past the external memory interface in one second. It is worked out by multiplying the bus width by its memory speed. In the case of DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This number is worked out 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 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 maximum amount of pixels the video card could possibly record to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
