GeForce RTX 2060 vs Radeon HD 6790

Intro

Compare all that to the Radeon HD 6790, which has core speeds of 840 MHz on the GPU, and 1050 MHz on the 1024 MB of GDDR5 RAM. It features 800 SPUs as well as 40 TAUs and 16 Rasterization Operator Units.

Radeon HD 6790		134400 MB/sec
	Difference: 209664 (156%)

Texel Rate

The GeForce RTX 2060 should be quite a bit (approximately 388%) better at AF than the Radeon HD 6790. (explain)

GeForce RTX 2060		163800 Mtexels/sec
Radeon HD 6790		33600 Mtexels/sec
	Difference: 130200 (388%)

Pixel Rate

The GeForce RTX 2060 is a lot (more or less 388%) better at FSAA than the Radeon HD 6790, and should be capable of handling higher screen resolutions without slowing down too much. (explain)

GeForce RTX 2060		65520 Mpixels/sec
Radeon HD 6790		13440 Mpixels/sec
	Difference: 52080 (388%)

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: Memory bandwidth is the max amount of data (in units of MB per second) that can be transferred over the external memory interface in a second. It is calculated by multiplying the interface width by the speed of its memory. If the card has DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This number is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one 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 figure is worked out by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called 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 memory bandwidth is, the lower the ability to get to the max fill rate.
