Compare any two graphics cards:
Radeon HD 4890 1GB vs Radeon RX 6500 XT
IntroThe Radeon HD 4890 1GB comes with a core clock frequency of 1000 MHz and a GDDR5 memory speed of 975 MHz. It also makes use of a 256-bit memory bus, and uses a 55 nm design. It features 800(160x5) SPUs, 40 TAUs, and 16 ROPs.Compare those specs to the Radeon RX 6500 XT, which has a core clock frequency of 2200 MHz and a GDDR6 memory speed of 2250 MHz. It also makes use of a 64-bit memory bus, and uses a 6 nm design. It is comprised of 1024 SPUs, 64 Texture Address Units, and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the Radeon RX 6500 XT should in theory be just a bit superior to the Radeon HD 4890 1GB in general. (explain)
Texel RateThe Radeon RX 6500 XT will be quite a bit (about 252%) better at AF than the Radeon HD 4890 1GB. (explain)
Pixel RateIf running with a high screen resolution is important to you, then the Radeon RX 6500 XT is superior to the Radeon HD 4890 1GB, 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 largest amount of information (measured in MB per second) that can be transferred over the external memory interface in one second. It's worked out by multiplying the card's interface width by the speed of its memory. In the case of DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This figure is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The higher 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 maximum number of pixels that the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
