GeForce RTX 2060 vs Radeon HD 7790

Intro

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

Radeon HD 7790		96000 MB/sec
	Difference: 248064 (258%)

Texel Rate

The GeForce RTX 2060 should be much (more or less 193%) better at anisotropic filtering than the Radeon HD 7790. (explain)

GeForce RTX 2060		163800 Mtexels/sec
Radeon HD 7790		56000 Mtexels/sec
	Difference: 107800 (193%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce RTX 2060 is the winner, by a large margin. (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: Bandwidth is the max amount of information (counted in MB per second) that can be transferred past the external memory interface in one second. It is calculated by multiplying the interface width by its memory clock speed. In the case of DDR memory, it must be multiplied by 2 again. If it uses 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, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better this number, the better the graphics card will be at 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 record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the the card's 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 rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
