Compare any two graphics cards:
GeForce GTX 1630 vs Radeon HD 4790
IntroThe GeForce GTX 1630 features clock speeds of 1740 MHz on the GPU, and 1500 MHz on the 4096 MB of GDDR6 memory. It features 512 SPUs along with 32 TAUs and 16 ROPs.Compare those specifications to the Radeon HD 4790, which comes with 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 Texture Address Units and 16 ROPs.

Power Usage and Theoretical BenchmarksMemory BandwidthIn theory, the Radeon HD 4790 is 4% quicker than the GeForce GTX 1630 in general, because of its higher bandwidth. (explain)
Texel RateThe GeForce GTX 1630 will be much (about 190%) better at texture filtering than the Radeon HD 4790. (explain)
Pixel RateThe GeForce GTX 1630 will be much (more or less 190%) faster with regards to full screen anti-aliasing than the Radeon HD 4790, and 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 maximum amount of data (in units of MB per second) that can be moved over the external memory interface within a second. It is calculated by multiplying the card's bus width by its memory clock speed. If the card has DDR type RAM, it 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, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This figure is worked out by multiplying the total number of texture units by the core clock speed of the chip. The higher the texel rate, 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 graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
