Radeon RX 590 vs Radeon RX 6950 XT

Intro

Compare all that to the Radeon RX 6950 XT, which features GPU clock speed of 1925 MHz, and 16384 MB of GDDR6 memory running at 2250 MHz through a 256-bit bus. It also is comprised of 5120 SPUs, 320 Texture Address Units, and 128 ROPs.

Radeon RX 590		262144 MB/sec
	Difference: 327680 (125%)

Texel Rate

The Radeon RX 6950 XT is quite a bit (approximately 191%) more effective at anisotropic filtering than the Radeon RX 590. (explain)

Radeon RX 6950 XT		616000 Mtexels/sec
Radeon RX 590		211536 Mtexels/sec
	Difference: 404464 (191%)

Pixel Rate

If using a high 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 RX 590		47008 Mpixels/sec
	Difference: 199392 (424%)

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 data (measured in MB per second) that can be moved over the external memory interface in one second. It's calculated by multiplying the card's bus width by its memory clock speed. If the card has DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the 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 number of texture map elements (texels) that are 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 the texel rate, the better the card will be at handling 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 card could possibly record to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the the core clock speed. 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 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 potential to get to the maximum fill rate.
