Radeon HD 5830 vs Radeon RX 6500 XT

Intro

Compare those specs to the Radeon RX 6500 XT, which comes with a core clock frequency of 2200 MHz and a GDDR6 memory speed of 2250 MHz. It also features a 64-bit memory bus, and uses a 6 nm design. It is made up of 1024 SPUs, 64 Texture Address Units, and 32 Raster Operation Units.

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

As far as performance goes, the Radeon RX 6500 XT should in theory be a little bit better than the Radeon HD 5830 in general. (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 (about 214%) more effective at anisotropic filtering than the Radeon HD 5830. (explain)

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

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon RX 6500 XT is superior to the Radeon HD 5830, and very much so. (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 largest amount of data (counted in MB per second) that can be transported over the external memory interface within a second. It is worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This number is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can 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 ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
