Compare any two graphics cards:
Radeon HD 7950 3GB vs Radeon RX 6600 XT
IntroThe Radeon HD 7950 3GB uses a 28 nm design. AMD has clocked the core speed at 800 MHz. The GDDR5 RAM runs at a speed of 1250 MHz on this particular card. It features 1792 SPUs along with 112 Texture Address Units and 32 ROPs.Compare that to the Radeon RX 6600 XT, which comes with GPU clock speed of 1968 MHz, and 8192 MB of GDDR6 RAM set to run at 2000 MHz through a 128-bit bus. It also is comprised of 2048 SPUs, 128 Texture Address Units, and 64 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the Radeon RX 6600 XT should theoretically be just a bit better than the Radeon HD 7950 3GB in general. (explain)
Texel RateThe Radeon RX 6600 XT is quite a bit (more or less 181%) better at texture filtering than the Radeon HD 7950 3GB. (explain)
Pixel RateIf running with lots of anti-aliasing is important to you, then the Radeon RX 6600 XT is superior to the Radeon HD 7950 3GB, by a large margin. (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 information (counted in megabytes per second) that can be transferred past the external memory interface within a second. The number is calculated by multiplying the card's bus width by its memory speed. If it uses DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This is calculated 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 texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second. Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the clock 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 output rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
