Compare any two graphics cards:
GeForce GTS 450 1GB vs Radeon RX 580
IntroThe GeForce GTS 450 1GB makes use of a 40 nm design. nVidia has set the core speed at 783 MHz. The GDDR5 memory is set to run at a speed of 902 MHz on this specific model. It features 192 SPUs along with 32 Texture Address Units and 16 Rasterization Operator Units.Compare that to the Radeon RX 580, which features GPU core speed of 1257 MHz, and 8192 MB of GDDR5 memory running at 2000 MHz through a 256-bit bus. It also features 2304 SPUs, 144 Texture Address Units, and 32 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon RX 580 should in theory perform quite a bit faster than the GeForce GTS 450 1GB in general. (explain)
Texel RateThe Radeon RX 580 is a lot (about 622%) more effective at texture filtering than the GeForce GTS 450 1GB. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the Radeon RX 580 is the winner, and very much so. (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 max amount of information (measured in MB per second) that can be moved over the external memory interface in a second. It's calculated by multiplying the interface width by its memory clock speed. In the case of DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This number is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second. Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
