Radeon RX 550 vs Radeon RX 6950 XT

Intro

Compare those specs to the Radeon RX 6950 XT, which features a core clock frequency of 1925 MHz and a GDDR6 memory frequency of 2250 MHz. It also makes use of a 256-bit bus, and uses a 7 nm design. It is comprised of 5120 SPUs, 320 Texture Address Units, and 128 ROPs.

The Radeon RX 6950 XT is much (more or less 1650%) better at texture filtering than the Radeon RX 550. (explain)

Radeon RX 6950 XT		616000 Mtexels/sec
Radeon RX 550		35200 Mtexels/sec
	Difference: 580800 (1650%)

Pixel Rate

If using a high resolution is important to you, then the Radeon RX 6950 XT is a better choice, and very much so. (explain)

Radeon RX 6950 XT		246400 Mpixels/sec
Radeon RX 550		17600 Mpixels/sec
	Difference: 228800 (1300%)

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 information (measured in MB per second) that can be transported past the external memory interface in a second. It's calculated by multiplying the card's interface width by its memory speed. If the card has DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This number is calculated by multiplying the total amount of texture units by the core 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 amount of pixels that the graphics chip can possibly write to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
