Compare any two graphics cards:
Radeon HD 7950 vs Radeon RX 6650 XT
IntroThe Radeon HD 7950 makes use of a 28 nm design. AMD has set the core frequency at 800 MHz. The GDDR5 RAM works at a frequency of 1250 MHz on this particular model. It features 1792 SPUs as well as 112 TAUs and 32 ROPs.Compare that to the Radeon RX 6650 XT, which makes use of a 7 nm design. AMD has set the core frequency at 2055 MHz. The GDDR6 RAM is set to run at a speed of 2190 MHz on this model. It features 2048 SPUs as well as 128 TAUs and 64 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the Radeon RX 6650 XT should be a bit faster than the Radeon HD 7950 in general. (explain)
Texel RateThe Radeon RX 6650 XT will be much (about 194%) faster with regards to texture filtering than the Radeon HD 7950. (explain)
Pixel RateThe Radeon RX 6650 XT is much (approximately 414%) more effective at full screen anti-aliasing than the Radeon HD 7950, and will be 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: Memory bandwidth is the maximum amount of data (in units of MB per second) that can be moved past the external memory interface in one second. The number is calculated by multiplying the card's bus width by its memory clock speed. In the case of DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better 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 texture map elements (texels) that are applied in one second. This figure is calculated by multiplying the total texture units by the core speed of the chip. The higher the texel rate, the better the video 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 most pixels that the graphics chip can possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
