GeForce RTX 2060 vs Radeon HD 7790

Intro

Compare all that to the Radeon HD 7790, which features a clock frequency of 1000 MHz and a GDDR5 memory frequency of 1500 MHz. It also uses a 128-bit memory bus, and makes use of a 28 nm design. It features 896 SPUs, 56 TAUs, and 16 Raster Operation Units.

Radeon HD 7790		56000 Mtexels/sec
	Difference: 107800 (193%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce RTX 2060 is superior to the Radeon HD 7790, and very much so. (explain)

GeForce RTX 2060		65520 Mpixels/sec
Radeon HD 7790		16000 Mpixels/sec
	Difference: 49520 (310%)

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 maximum amount of information (in units of MB per second) that can be transferred over the external memory interface in a second. It's worked out by multiplying the card's bus width by its memory speed. In the case of DDR type RAM, the result should be multiplied by 2 once 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 processed per second. This number is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly write 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 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 rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
