Radeon R9 Nano vs Radeon RX 6750 XT

Intro

Compare that to the Radeon RX 6750 XT, which comes with core speeds of 2150 MHz on the GPU, and 2250 MHz on the 12288 MB of GDDR6 RAM. It features 2560 SPUs along with 160 TAUs and 64 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon R9 Nano		175 Watts
Radeon RX 6750 XT		250 Watts
	Difference: 75 Watts (43%)

Memory Bandwidth

In theory, the Radeon R9 Nano will be 16% faster than the Radeon RX 6750 XT overall, due to its greater bandwidth. (explain)

Radeon R9 Nano		512000 MB/sec
Radeon RX 6750 XT		442368 MB/sec
	Difference: 69632 (16%)

Texel Rate

The Radeon RX 6750 XT should be much (about 34%) more effective at AF than the Radeon R9 Nano. (explain)

Radeon RX 6750 XT		344000 Mtexels/sec
Radeon R9 Nano		256000 Mtexels/sec
	Difference: 88000 (34%)

Pixel Rate

The Radeon RX 6750 XT should be quite a bit (approximately 115%) more effective at anti-aliasing than the Radeon R9 Nano, and also able to handle higher screen resolutions more effectively. (explain)

Radeon RX 6750 XT		137600 Mpixels/sec
Radeon R9 Nano		64000 Mpixels/sec
	Difference: 73600 (115%)

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 max amount of data (in units of MB per second) that can be transferred past the external memory interface within a second. It's worked out by multiplying the card's bus width by its memory clock speed. If the card has DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, 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 texture map elements (texels) that can be applied per second. This is worked out by multiplying the total texture units by the core speed of the chip. The better the texel rate, the better the 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 in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
