Compare any two graphics cards:
GeForce GTX 1650 vs Radeon HD 4850 512MB
IntroThe GeForce GTX 1650 features clock speeds of 1485 MHz on the GPU, and 2001 MHz on the 4096 MB of GDDR5 memory. It features 896 SPUs along with 56 TAUs and 32 ROPs.Compare all that to the Radeon HD 4850 512MB, which has clock speeds of 625 MHz on the GPU, and 993 MHz on the 512 MB of GDDR3 memory. It features 800(160x5) SPUs as well as 40 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the GeForce GTX 1650 will be 106% quicker than the Radeon HD 4850 512MB in general, because of its higher bandwidth. (explain)
Texel RateThe GeForce GTX 1650 will be quite a bit (about 233%) more effective at texture filtering than the Radeon HD 4850 512MB. (explain)
Pixel RateThe GeForce GTX 1650 should be quite a bit (about 375%) faster with regards to FSAA than the Radeon HD 4850 512MB, and also should be able to handle higher resolutions without slowing down too much. (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 largest amount of data (measured in MB per second) that can be moved past the external memory interface within a second. It is calculated by multiplying the card's interface width by its memory clock speed. If the card has DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better 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 are processed per second. This is worked out by multiplying the total amount of texture units by the core speed of the chip. The higher this number, the better the graphics 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 the video card can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
