Compare any two graphics cards:
Radeon HD 4890 2GB vs Radeon RX 6500 XT
IntroThe Radeon HD 4890 2GB features a GPU clock speed of 1000 MHz, and the 2048 MB of GDDR5 memory runs at 975 MHz through a 256-bit bus. It also is made up of 800(160x5) SPUs, 40 TAUs, and 16 Raster Operation Units.Compare that to the Radeon RX 6500 XT, which comes with a clock frequency of 2200 MHz and a GDDR6 memory frequency of 2250 MHz. It also features a 64-bit memory bus, and makes use of a 6 nm design. It is comprised of 1024 SPUs, 64 Texture Address Units, and 32 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon RX 6500 XT, in theory, should be a bit faster than the Radeon HD 4890 2GB in general. (explain)
Texel RateThe Radeon RX 6500 XT should be a lot (approximately 252%) better at AF than the Radeon HD 4890 2GB. (explain)
Pixel RateThe Radeon RX 6500 XT is a lot (approximately 340%) more effective at AA than the Radeon HD 4890 2GB, and capable of handling higher 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 max amount of data (in units of megabytes per second) that can be transported over the external memory interface within a second. It is worked out by multiplying the interface width by its memory clock speed. In the case of DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher 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 amount of texture map elements (texels) that are applied per second. This is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second. Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka 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 max fill rate.
