Radeon RX 6950 XT vs Radeon RX Vega 56

Intro

Compare all of that to the Radeon RX Vega 56, which makes use of a 14 nm design. AMD has set the core speed at 1156 MHz. The HBM2 memory is set to run at a frequency of 1600 MHz on this specific model. It features 3584 SPUs along with 224 TAUs and 64 ROPs.

Radeon RX Vega 56		210 Watts
Radeon RX 6950 XT		335 Watts
	Difference: 125 Watts (60%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 6950 XT is 41% quicker than the Radeon RX Vega 56 in general, due to its higher data rate. (explain)

Radeon RX 6950 XT		589824 MB/sec
Radeon RX Vega 56		419430 MB/sec
	Difference: 170394 (41%)

Texel Rate

The Radeon RX 6950 XT is much (approximately 138%) faster with regards to AF than the Radeon RX Vega 56. (explain)

Radeon RX 6950 XT		616000 Mtexels/sec
Radeon RX Vega 56		258944 Mtexels/sec
	Difference: 357056 (138%)

Pixel Rate

The Radeon RX 6950 XT should be a lot (approximately 233%) more effective at FSAA than the Radeon RX Vega 56, and will be capable of handling higher resolutions while still performing well. (explain)

Radeon RX 6950 XT		246400 Mpixels/sec
Radeon RX Vega 56		73984 Mpixels/sec
	Difference: 172416 (233%)

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 maximum amount of data (in units of megabytes per second) that can be transferred over the external memory interface in a second. It is worked out by multiplying the card's bus width by its memory speed. If the card has DDR type RAM, the result should be multiplied by 2 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 anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the the core speed of the card. 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 output rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
