Compare any two graphics cards:
Radeon HD 7950 vs Radeon RX 6650 XT
IntroThe Radeon HD 7950 uses a 28 nm design. AMD has clocked the core frequency at 800 MHz. The GDDR5 RAM works at a frequency of 1250 MHz on this card. It features 1792 SPUs as well as 112 Texture Address Units and 32 Rasterization Operator Units.Compare that to the Radeon RX 6650 XT, which has core clock speeds of 2055 MHz on the GPU, and 2190 MHz on the 8192 MB of GDDR6 memory. It features 2048 SPUs as well as 128 TAUs and 64 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon RX 6650 XT, in theory, should perform a small bit faster than the Radeon HD 7950 overall. (explain)
Texel RateThe Radeon RX 6650 XT is quite a bit (approximately 194%) better at anisotropic filtering than the Radeon HD 7950. (explain)
Pixel RateThe Radeon RX 6650 XT will be a lot (more or less 414%) better at AA than the Radeon HD 7950, and will be able to handle higher screen resolutions while still performing well. (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 maximum amount of data (counted in megabytes per second) that can be transported past the external memory interface in a second. It is calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better 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 amount of texture map elements (texels) that can be applied in one second. This is calculated 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 per second. Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines 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 also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
