Compare any two graphics cards:
GeForce GTX 1630 vs Radeon HD 4790
IntroThe GeForce GTX 1630 features a core clock frequency of 1740 MHz and a GDDR6 memory speed of 1500 MHz. It also uses a 64-bit bus, and uses a 12 nm design. It is comprised of 512 SPUs, 32 Texture Address Units, and 16 ROPs.Compare that to the Radeon HD 4790, which features core clock speeds of 600 MHz on the GPU, and 800 MHz on the 512 MB of GDDR5 RAM. It features 640(128x5) SPUs as well as 32 TAUs and 16 Rasterization Operator Units.
Display Graphs
Power Usage and Theoretical BenchmarksMemory BandwidthIn theory, the Radeon HD 4790 will be 4% faster than the GeForce GTX 1630 overall, due to its greater data rate. (explain)
Texel RateThe GeForce GTX 1630 should be much (more or less 190%) more effective at anisotropic filtering than the Radeon HD 4790. (explain)
Pixel RateThe GeForce GTX 1630 is much (approximately 190%) better at AA than the Radeon HD 4790, and also able to handle higher screen 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 maximum amount of information (in units of MB per second) that can be transferred past the external memory interface in a second. It's worked out by multiplying the bus width by the speed of its memory. If the card has DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better 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 texture map elements (texels) that can be applied per second. This is worked out by multiplying the total amount 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 in one second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
