Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 6500 XT		107 Watts
Radeon HD 5830		175 Watts
	Difference: 68 Watts (64%)

Memory Bandwidth

In theory, the Radeon RX 6500 XT will be 15% quicker than the Radeon HD 5830 overall, due to its higher bandwidth. (explain)

Radeon RX 6500 XT		147456 MB/sec
Radeon HD 5830		128000 MB/sec
	Difference: 19456 (15%)

Texel Rate

The Radeon RX 6500 XT should be quite a bit (more or less 214%) more effective at AF than the Radeon HD 5830. (explain)

Radeon RX 6500 XT		140800 Mtexels/sec
Radeon HD 5830		44800 Mtexels/sec
	Difference: 96000 (214%)

Pixel Rate

The Radeon RX 6500 XT should be much (about 450%) more effective at FSAA than the Radeon HD 5830, and able to handle higher screen resolutions without slowing down too much. (explain)

Radeon RX 6500 XT		70400 Mpixels/sec
Radeon HD 5830		12800 Mpixels/sec
	Difference: 57600 (450%)

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 maximum amount of information (counted in megabytes per second) that can be moved across the external memory interface within a second. The number is calculated by multiplying the interface width by the speed of its memory. If it uses DDR memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better 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 texture map elements (texels) that are processed in one second. This number is worked out by multiplying the total 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 applied in a second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly record to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs 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 rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
