Radeon R9 Nano vs Radeon RX 6600 XT

Intro

Compare that to the Radeon RX 6600 XT, which comes with a core clock speed of 1968 MHz and a GDDR6 memory speed of 2000 MHz. It also makes use of a 128-bit bus, and uses a 7 nm design. It features 2048 SPUs, 128 Texture Address Units, and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 6600 XT		160 Watts
Radeon R9 Nano		175 Watts
	Difference: 15 Watts (9%)

Memory Bandwidth

Theoretically speaking, the Radeon R9 Nano should be 95% quicker than the Radeon RX 6600 XT in general, due to its greater data rate. (explain)

Radeon R9 Nano		512000 MB/sec
Radeon RX 6600 XT		262144 MB/sec
	Difference: 249856 (95%)

Texel Rate

The Radeon R9 Nano will be just a bit (approximately 2%) faster with regards to texture filtering than the Radeon RX 6600 XT. (explain)

Radeon R9 Nano		256000 Mtexels/sec
Radeon RX 6600 XT		251904 Mtexels/sec
	Difference: 4096 (2%)

Pixel Rate

The Radeon RX 6600 XT should be quite a bit (approximately 97%) more effective at anti-aliasing than the Radeon R9 Nano, and should be able to handle higher resolutions without slowing down too much. (explain)

Radeon RX 6600 XT		125952 Mpixels/sec
Radeon R9 Nano		64000 Mpixels/sec
	Difference: 61952 (97%)

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 max amount of information (in units of megabytes per second) that can be transferred across the external memory interface in a second. It's calculated by multiplying the interface width by its memory clock speed. In the case of DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This figure is worked out by multiplying the total texture units by the core clock speed of the chip. The higher the texel rate, the better the video 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 most pixels that the graphics chip can possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
