Radeon R9 Nano vs Radeon RX 6950 XT

Intro

Compare all that to the Radeon RX 6950 XT, which features a core clock speed of 1925 MHz and a GDDR6 memory speed of 2250 MHz. It also features a 256-bit bus, and makes use of a 7 nm design. It is made up of 5120 SPUs, 320 Texture Address Units, and 128 Raster Operation Units.

Radeon R9 Nano		512000 MB/sec
	Difference: 77824 (15%)

Texel Rate

The Radeon RX 6950 XT will be a lot (more or less 141%) faster with regards to AF than the Radeon R9 Nano. (explain)

Radeon RX 6950 XT		616000 Mtexels/sec
Radeon R9 Nano		256000 Mtexels/sec
	Difference: 360000 (141%)

Pixel Rate

If using a high screen resolution is important to you, then the Radeon RX 6950 XT is a better choice, by far. (explain)

Radeon RX 6950 XT		246400 Mpixels/sec
Radeon R9 Nano		64000 Mpixels/sec
	Difference: 182400 (285%)

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 data (in units of megabytes per second) that can be transferred past the external memory interface in one second. The number is worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total texture units of the card by the core speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
