Radeon HD 4850 X2 512MB vs Radeon RX 6500 XT

Intro

Compare those specs to the Radeon RX 6500 XT, which makes use of a 6 nm design. AMD has clocked the core frequency at 2200 MHz. The GDDR6 RAM runs at a frequency of 2250 MHz on this specific card. It features 1024 SPUs along with 64 Texture Address Units and 32 Rasterization Operator Units.

The Radeon RX 6500 XT will be much (about 182%) more effective at anisotropic filtering than the Radeon HD 4850 X2 512MB. (explain)

Radeon RX 6500 XT		140800 Mtexels/sec
Radeon HD 4850 X2 512MB		50000 Mtexels/sec
	Difference: 90800 (182%)

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 4850 X2 512MB, by far. (explain)

Radeon RX 6500 XT		70400 Mpixels/sec
Radeon HD 4850 X2 512MB		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 max amount of data (measured in MB per second) that can be transported over the external memory interface within a second. It's calculated by multiplying the card's interface width by the speed of its memory. If the card has DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, 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 number of texture map elements (texels) that are applied per second. This figure is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
