GeForce RTX 2080 vs Radeon RX 6950 XT

Intro

Compare those specifications to the Radeon RX 6950 XT, which makes use of a 7 nm design. AMD has clocked the core frequency at 1925 MHz. The GDDR6 memory is set to run at a speed of 2250 MHz on this model. It features 5120 SPUs along with 320 TAUs and 128 Rasterization Operator Units.

GeForce RTX 2080		458752 MB/sec
	Difference: 131072 (29%)

Texel Rate

The Radeon RX 6950 XT is quite a bit (about 121%) more effective at AF than the GeForce RTX 2080. (explain)

Radeon RX 6950 XT		616000 Mtexels/sec
GeForce RTX 2080		278760 Mtexels/sec
	Difference: 337240 (121%)

Pixel Rate

The Radeon RX 6950 XT should be a lot (more or less 154%) faster with regards to AA than the GeForce RTX 2080, and also should be able to handle higher screen resolutions better. (explain)

Radeon RX 6950 XT		246400 Mpixels/sec
GeForce RTX 2080		96960 Mpixels/sec
	Difference: 149440 (154%)

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 information (counted in MB per second) that can be transferred across the external memory interface in one second. It's worked out by multiplying the card's interface width by the speed of its memory. In the case of DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. 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 applied in one second. This number is worked out by multiplying the total amount of texture units by the core speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as 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, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
