Radeon HD 4850 X2 1GB 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 runs at a frequency of 2250 MHz on this specific card. It features 1024 SPUs along with 64 TAUs and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 6500 XT		107 Watts
Radeon HD 4850 X2 1GB		250 Watts
	Difference: 143 Watts (134%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 6500 XT will be 16% faster than the Radeon HD 4850 X2 1GB overall, because of its greater bandwidth. (explain)

Radeon RX 6500 XT		147456 MB/sec
Radeon HD 4850 X2 1GB		127104 MB/sec
	Difference: 20352 (16%)

Texel Rate

The Radeon RX 6500 XT should be much (more or less 182%) faster with regards to AF than the Radeon HD 4850 X2 1GB. (explain)

Radeon RX 6500 XT		140800 Mtexels/sec
Radeon HD 4850 X2 1GB		50000 Mtexels/sec
	Difference: 90800 (182%)

Pixel Rate

The Radeon RX 6500 XT should be a lot (approximately 252%) more effective at anti-aliasing than the Radeon HD 4850 X2 1GB, and also should be able to handle higher resolutions without losing too much performance. (explain)

Radeon RX 6500 XT		70400 Mpixels/sec
Radeon HD 4850 X2 1GB		20000 Mpixels/sec
	Difference: 50400 (252%)

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.

One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.

Specifications

Memory Bandwidth: Memory bandwidth is the maximum amount of information (counted in megabytes per second) that can be transported past the external memory interface in one second. It's calculated by multiplying the card's bus width by its memory speed. If it uses DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
