Compare any two graphics cards:
Radeon HD 7950 3GB vs Radeon RX 6650 XT
IntroThe Radeon HD 7950 3GB comes with a clock speed of 800 MHz and a GDDR5 memory speed of 1250 MHz. It also features a 384-bit memory bus, and uses a 28 nm design. It is made up of 1792 SPUs, 112 TAUs, and 32 ROPs.Compare that to the Radeon RX 6650 XT, which has GPU core speed of 2055 MHz, and 8192 MB of GDDR6 memory set to run at 2190 MHz through a 128-bit bus. It also is made up of 2048 Stream Processors, 128 TAUs, and 64 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the Radeon RX 6650 XT should theoretically be a little bit better than the Radeon HD 7950 3GB overall. (explain)
Texel RateThe Radeon RX 6650 XT is a lot (more or less 194%) better at anisotropic filtering than the Radeon HD 7950 3GB. (explain)
Pixel RateIf using a high screen resolution is important to you, then the Radeon RX 6650 XT is superior to the Radeon HD 7950 3GB, and very much so. (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. Price Comparison

Display Specifications
Memory Bandwidth: Bandwidth is the max amount of information (counted in megabytes per second) that can be moved past the external memory interface within a second. The number is calculated by multiplying the card's bus width by its memory speed. If the card has DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This number is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the graphics 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 amount of pixels the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs 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 fill rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
