Radeon HD 5830 vs Radeon RX 6500 XT

Intro

Compare all of that to the Radeon RX 6500 XT, which uses a 6 nm design. AMD has clocked the core speed at 2200 MHz. The GDDR6 memory works at a speed of 2250 MHz on this specific card. It features 1024 SPUs as well as 64 TAUs and 32 Rasterization Operator 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

Theoretically speaking, the Radeon RX 6500 XT should be 15% faster than the Radeon HD 5830 overall, because of its greater 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 will be much (approximately 214%) better 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

If running with lots of anti-aliasing is important to you, then the Radeon RX 6500 XT is the winner, by a large margin. (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: Memory bandwidth is the largest amount of information (in units of MB per second) that can be transferred past the external memory interface in one second. It is worked out by multiplying the card's interface width by the speed of its memory. In the case of DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better 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 amount of texture map elements (texels) that are processed in one second. This number is calculated by multiplying the total texture units by the core speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as 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 of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
