Radeon R9 Nano vs Radeon RX 6950 XT

Intro

Compare those specs to the Radeon RX 6950 XT, which uses a 7 nm design. AMD has clocked the core speed at 1925 MHz. The GDDR6 RAM works at a frequency of 2250 MHz on this particular card. It features 5120 SPUs along with 320 Texture Address Units and 128 Rasterization Operator Units.

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

Texel Rate

The Radeon RX 6950 XT is quite a bit (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

The Radeon RX 6950 XT is much (about 285%) more effective at anti-aliasing than the Radeon R9 Nano, and also will be capable of handling higher screen resolutions without slowing down too much. (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: Memory bandwidth is the largest amount of information (counted in megabytes per second) that can be moved over the external memory interface in a second. It's calculated by multiplying the interface width by the speed of its memory. If the card has DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's 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 in one second. This is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
