Compare any two graphics cards:
Radeon HD 7950 vs Radeon RX 6650 XT
IntroThe Radeon HD 7950 has a clock speed of 800 MHz and a GDDR5 memory frequency of 1250 MHz. It also makes use of a 384-bit bus, and makes use of a 28 nm design. It is comprised of 1792 SPUs, 112 Texture Address Units, and 32 Raster Operation Units.Compare that to the Radeon RX 6650 XT, which comes with a clock frequency of 2055 MHz and a GDDR6 memory speed of 2190 MHz. It also makes use of a 128-bit memory bus, and uses a 7 nm design. It is comprised of 2048 SPUs, 128 Texture Address Units, and 64 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the Radeon RX 6650 XT should be a little bit faster than the Radeon HD 7950 overall. (explain)
Texel RateThe Radeon RX 6650 XT will be a lot (approximately 194%) better at AF than the Radeon HD 7950. (explain)
Pixel RateThe Radeon RX 6650 XT should be much (approximately 414%) better at anti-aliasing than the Radeon HD 7950, and also should be capable of handling higher screen resolutions more effectively. (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 information (measured in MB per second) that can be transported across the external memory interface in a second. It is worked out by multiplying the card's interface width by its memory speed. In the case of DDR memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This 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 handling 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 that the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
