Compare any two graphics cards:
Radeon HD 7950 vs Radeon RX 6650 XT
IntroThe Radeon HD 7950 has a GPU clock speed of 800 MHz, and the 1536 MB of GDDR5 memory is set to run at 1250 MHz through a 384-bit bus. It also is made up of 1792 Stream Processors, 112 TAUs, and 32 ROPs.Compare those specs to the Radeon RX 6650 XT, which uses a 7 nm design. AMD has clocked the core speed at 2055 MHz. The GDDR6 memory is set to run at a speed of 2190 MHz on this particular model. It features 2048 SPUs along with 128 Texture Address Units and 64 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the Radeon RX 6650 XT should in theory be a small bit better than the Radeon HD 7950 overall. (explain)
Texel RateThe Radeon RX 6650 XT should be a lot (more or less 194%) faster with regards to texture filtering than the Radeon HD 7950. (explain)
Pixel RateThe Radeon RX 6650 XT will be quite a bit (approximately 414%) faster with regards to AA than the Radeon HD 7950, and also able to handle higher resolutions better. (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 largest amount of information (counted in 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 clock speed. If the card has DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This number is calculated by multiplying the total number of texture units by the core clock speed of the chip. The higher the texel rate, the better the 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 amount of pixels that the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the the core 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 fill rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
