Radeon RX 5500 vs Radeon RX 6800

Intro

Compare all of that to the Radeon RX 6800, which has GPU clock speed of 1700 MHz, and 16384 MB of GDDR6 RAM set to run at 2000 MHz through a 256-bit bus. It also is made up of 3840 Stream Processors, 240 TAUs, and 96 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 5500		150 Watts
Radeon RX 6800		250 Watts
	Difference: 100 Watts (67%)

Memory Bandwidth

Performance-wise, the Radeon RX 6800 should in theory be much superior to the Radeon RX 5500 overall. (explain)

Radeon RX 6800		524288 MB/sec
Radeon RX 5500		229376 MB/sec
	Difference: 294912 (129%)

Texel Rate

The Radeon RX 6800 should be a lot (approximately 178%) more effective at anisotropic filtering than the Radeon RX 5500. (explain)

Radeon RX 6800		408000 Mtexels/sec
Radeon RX 5500		146960 Mtexels/sec
	Difference: 261040 (178%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon RX 6800 is the winner, and very much so. (explain)

Radeon RX 6800		163200 Mpixels/sec
Radeon RX 5500		53440 Mpixels/sec
	Difference: 109760 (205%)

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 largest amount of data (counted in megabytes per second) that can be transported over the external memory interface in one second. It is calculated by multiplying the card's bus width by its memory clock speed. If the card has DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, 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 figure is worked out by multiplying the total amount of texture units by the core speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
