Compare any two graphics cards:
Radeon HD 7970 vs Radeon RX 6650 XT
IntroThe Radeon HD 7970 makes use of a 28 nm design. AMD has clocked the core frequency at 925 MHz. The GDDR5 RAM is set to run at a speed of 1375 MHz on this particular model. It features 2048 SPUs along with 128 Texture Address Units and 32 ROPs.Compare those specifications to the Radeon RX 6650 XT, which has GPU clock speed of 2055 MHz, and 8192 MB of GDDR6 RAM set to run at 2190 MHz through a 128-bit bus. It also features 2048 Stream Processors, 128 TAUs, and 64 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically, the Radeon RX 6650 XT should perform a small bit faster than the Radeon HD 7970 overall. (explain)
Texel RateThe Radeon RX 6650 XT is quite a bit (more or less 122%) more effective at texture filtering than the Radeon HD 7970. (explain)
Pixel RateThe Radeon RX 6650 XT is a lot (about 344%) faster with regards to FSAA than the Radeon HD 7970, and should be capable of handling higher 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 max amount of data (in units of megabytes per second) that can be transferred over the external memory interface in one second. The number is worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This is worked out by multiplying the total texture units by the core speed of the chip. The better the texel rate, the better the video 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 that the graphics chip can possibly record to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
