Compare any two graphics cards:
Radeon HD 4870 X2 vs Radeon RX 6600
IntroThe Radeon HD 4870 X2 makes use of a 55 nm design. AMD has clocked the core frequency at 750 MHz. The GDDR5 memory works at a speed of 900 MHz on this particular card. It features 800(160x5) SPUs along with 40 Texture Address Units and 16 ROPs.Compare all of that to the Radeon RX 6600, which comes with a GPU core clock speed of 1626 MHz, and 8192 MB of GDDR6 memory running at 1750 MHz through a 128-bit bus. It also is made up of 1792 Stream Processors, 112 Texture Address Units, and 64 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon HD 4870 X2 should in theory perform just a bit faster than the Radeon RX 6600 in general. (explain)
Texel RateThe Radeon RX 6600 is quite a bit (about 204%) faster with regards to anisotropic filtering than the Radeon HD 4870 X2. (explain)
Pixel RateIf running with high levels of AA is important to you, then the Radeon RX 6600 is the winner, 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: Bandwidth is the max amount of information (in units of megabytes per second) that can be transferred across the external memory interface in one second. It's worked out by multiplying the card's interface width by its memory speed. If the card has DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
