GeForce RTX 2060 vs Radeon HD 5870

Intro

Compare those specifications to the Radeon HD 5870, which comes with a core clock speed of 850 MHz and a GDDR5 memory frequency of 1200 MHz. It also makes use of a 256-bit bus, and uses a 40 nm design. It is comprised of 1600(320x5) SPUs, 80 Texture Address Units, and 32 ROPs.

Theoretically speaking, the GeForce RTX 2060 is 124% quicker than the Radeon HD 5870 in general, due to its greater bandwidth. (explain)

GeForce RTX 2060		344064 MB/sec
Radeon HD 5870		153600 MB/sec
	Difference: 190464 (124%)

Texel Rate

The GeForce RTX 2060 should be much (approximately 141%) faster with regards to AF than the Radeon HD 5870. (explain)

GeForce RTX 2060		163800 Mtexels/sec
Radeon HD 5870		68000 Mtexels/sec
	Difference: 95800 (141%)

Pixel Rate

The GeForce RTX 2060 is quite a bit (approximately 141%) more effective at full screen anti-aliasing than the Radeon HD 5870, and also will be capable of handling higher resolutions while still performing well. (explain)

GeForce RTX 2060		65520 Mpixels/sec
Radeon HD 5870		27200 Mpixels/sec
	Difference: 38320 (141%)

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 information (counted in megabytes per second) that can be moved past the external memory interface in a second. It's worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the video card can possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
