Radeon RX Vega 64		495411 MB/sec
	Difference: 135373 (27%)

Texel Rate

The GeForce RTX 2080 Ti will be a little bit (more or less 15%) faster with regards to AF than the Radeon RX Vega 64. (explain)

GeForce RTX 2080 Ti		367200 Mtexels/sec
Radeon RX Vega 64		319232 Mtexels/sec
	Difference: 47968 (15%)

Pixel Rate

The GeForce RTX 2080 Ti is quite a bit (about 49%) better at full screen anti-aliasing than the Radeon RX Vega 64, and should be able to handle higher resolutions while still performing well. (explain)

GeForce RTX 2080 Ti		118800 Mpixels/sec
Radeon RX Vega 64		79808 Mpixels/sec
	Difference: 38992 (49%)

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 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 it uses DDR memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster 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 texture map elements (texels) that are applied in one second. This is calculated by multiplying the total texture units of the card by the core 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 per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka 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 get to the maximum fill rate.
