Radeon RX 6500 XT vs Radeon RX 6800

Intro

Compare all that to the Radeon RX 6800, which uses a 7 nm design. AMD has clocked the core speed at 1700 MHz. The GDDR6 memory works at a speed of 2000 MHz on this specific card. It features 3840 SPUs along with 240 Texture Address Units and 96 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 6500 XT		107 Watts
Radeon RX 6800		250 Watts
	Difference: 143 Watts (134%)

Memory Bandwidth

As far as performance goes, the Radeon RX 6800 should in theory be a lot superior to the Radeon RX 6500 XT overall. (explain)

Radeon RX 6800		524288 MB/sec
Radeon RX 6500 XT		147456 MB/sec
	Difference: 376832 (256%)

Texel Rate

The Radeon RX 6800 will be quite a bit (about 190%) more effective at texture filtering than the Radeon RX 6500 XT. (explain)

Radeon RX 6800		408000 Mtexels/sec
Radeon RX 6500 XT		140800 Mtexels/sec
	Difference: 267200 (190%)

Pixel Rate

If using a high resolution 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 6500 XT		70400 Mpixels/sec
	Difference: 92800 (132%)

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 (measured in megabytes per second) that can be transferred past the external memory interface in one second. It's calculated by multiplying the bus width by its memory clock speed. If it uses DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, 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 amount of texture map elements (texels) that are processed per second. This figure is worked out 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 card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
