Compare any two graphics cards:
Radeon HD 4850 X2 512MB vs Radeon RX 6600 XT
IntroThe Radeon HD 4850 X2 512MB uses a 55 nm design. AMD has clocked the core frequency at 625 MHz. The GDDR3 RAM runs at a frequency of 993 MHz on this particular card. It features 800(160x5) SPUs as well as 40 TAUs and 16 Rasterization Operator Units.Compare those specs to the Radeon RX 6600 XT, which has a core clock frequency of 1968 MHz and a GDDR6 memory frequency of 2000 MHz. It also features a 128-bit memory bus, and makes use of a 7 nm design. It features 2048 SPUs, 128 Texture Address Units, and 64 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon RX 6600 XT should theoretically be much faster than the Radeon HD 4850 X2 512MB overall. (explain)
Texel RateThe Radeon RX 6600 XT will be quite a bit (more or less 404%) better at AF than the Radeon HD 4850 X2 512MB. (explain)
Pixel RateIf using a high resolution is important to you, then the Radeon RX 6600 XT is superior to the Radeon HD 4850 X2 512MB, by a large margin. (explain)
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. Price Comparison

Display Specifications
Memory Bandwidth: Memory bandwidth is the max amount of data (measured in MB per second) that can be moved over the external memory interface in one second. It is calculated by multiplying the interface width by the speed of its memory. If the card has DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This number is calculated by multiplying the total amount of 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 one second. Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
