Radeon HD 7850 vs Radeon RX 6950 XT

Intro

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

Radeon HD 7850		130 Watts
Radeon RX 6950 XT		335 Watts
	Difference: 205 Watts (158%)

Memory Bandwidth

The Radeon RX 6950 XT, in theory, should perform a lot faster than the Radeon HD 7850 overall. (explain)

Radeon RX 6950 XT		589824 MB/sec
Radeon HD 7850		153600 MB/sec
	Difference: 436224 (284%)

Texel Rate

The Radeon RX 6950 XT will be a lot (about 1019%) more effective at texture filtering than the Radeon HD 7850. (explain)

Radeon RX 6950 XT		616000 Mtexels/sec
Radeon HD 7850		55040 Mtexels/sec
	Difference: 560960 (1019%)

Pixel Rate

If using lots of anti-aliasing 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 HD 7850		27520 Mpixels/sec
	Difference: 218880 (795%)

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 (in units of megabytes per second) that can be transported across the external memory interface within a second. It is worked out by multiplying the card's interface width by its memory speed. If the card has DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
