Compare any two graphics cards:
GeForce GTX 1630 vs Radeon HD 4890 2GB
IntroThe GeForce GTX 1630 comes with core clock speeds of 1740 MHz on the GPU, and 1500 MHz on the 4096 MB of GDDR6 memory. It features 512 SPUs as well as 32 TAUs and 16 Rasterization Operator Units.Compare those specs to the Radeon HD 4890 2GB, which has a clock frequency of 1000 MHz and a GDDR5 memory speed of 975 MHz. It also features a 256-bit memory bus, and uses a 55 nm design. It is comprised of 800(160x5) SPUs, 40 TAUs, and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the Radeon HD 4890 2GB will be 27% faster than the GeForce GTX 1630 overall, due to its higher bandwidth. (explain)
Texel RateThe GeForce GTX 1630 should be quite a bit (about 39%) better at texture filtering than the Radeon HD 4890 2GB. (explain)
Pixel RateThe GeForce GTX 1630 should be a lot (more or less 74%) faster with regards to anti-aliasing than the Radeon HD 4890 2GB, and will be able to handle higher screen 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: Bandwidth is the maximum amount of data (counted in MB per second) that can be moved over the external memory interface in one second. The number is calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR type RAM, the result should be multiplied by 2 once 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, HDR and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This number is calculated by multiplying the total number of texture units by the core clock speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second. Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called 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 bandwidth is, the lower the ability to reach the maximum fill rate.
