	Difference: 470784 (294%)

Texel Rate

The GeForce RTX 2080 Ti should be quite a bit (approximately 297%) better at anisotropic filtering than the Radeon R9 M395X. (explain)

GeForce RTX 2080 Ti		367200 Mtexels/sec
Radeon R9 M395X		92544 Mtexels/sec
	Difference: 274656 (297%)

Pixel Rate

The GeForce RTX 2080 Ti will be quite a bit (more or less 413%) faster with regards to AA than the Radeon R9 M395X, and also will be able to handle higher resolutions while still performing well. (explain)

GeForce RTX 2080 Ti		118800 Mpixels/sec
Radeon R9 M395X		23136 Mpixels/sec
	Difference: 95664 (413%)

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 past the external memory interface in a second. The number is worked out by multiplying the bus width by the speed of its memory. If it uses DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This is calculated by multiplying the total number of texture units by the core clock 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 in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour 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 fill rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
