Radeon HD 6850 vs Radeon RX 5500

Intro

Compare those specifications to the Radeon RX 5500, which uses a 7 nm design. AMD has set the core frequency at 1670 MHz. The GDDR6 RAM works at a frequency of 1750 MHz on this model. It features 1408 SPUs along with 88 Texture Address Units and 32 Rasterization Operator Units.

Radeon HD 6850		128000 MB/sec
	Difference: 101376 (79%)

Texel Rate

The Radeon RX 5500 is quite a bit (more or less 295%) more effective at AF than the Radeon HD 6850. (explain)

Radeon RX 5500		146960 Mtexels/sec
Radeon HD 6850		37200 Mtexels/sec
	Difference: 109760 (295%)

Pixel Rate

If running with a high resolution is important to you, then the Radeon RX 5500 is superior to the Radeon HD 6850, by far. (explain)

Radeon RX 5500		53440 Mpixels/sec
Radeon HD 6850		24800 Mpixels/sec
	Difference: 28640 (115%)

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 data (measured in MB per second) that can be moved over the external memory interface in one second. It's worked out by multiplying the interface width by the speed of its memory. In the case of DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher 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 are applied 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 higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units 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 lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
