Compare any two graphics cards:
Radeon HD 6750 1GB vs Radeon RX 580
IntroThe Radeon HD 6750 1GB features a GPU clock speed of 725 MHz, and the 1024 MB of GDDR5 memory runs at 1000 MHz through a 128-bit bus. It also features 720 Stream Processors, 36 TAUs, and 16 Raster Operation Units.Compare those specs to the Radeon RX 580, which uses a 14 nm design. AMD has clocked the core speed at 1257 MHz. The GDDR5 RAM is set to run at a speed of 2000 MHz on this specific card. It features 2304 SPUs along with 144 TAUs and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon RX 580 should theoretically be quite a bit faster than the Radeon HD 6750 1GB overall. (explain)
Texel RateThe Radeon RX 580 is a lot (approximately 594%) faster with regards to anisotropic filtering than the Radeon HD 6750 1GB. (explain)
Pixel RateThe Radeon RX 580 is quite a bit (about 247%) faster with regards to anti-aliasing than the Radeon HD 6750 1GB, and also should be capable of handling 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: Bandwidth is the max amount of information (measured in megabytes per second) that can be transferred over the external memory interface in a second. It's calculated by multiplying the card's interface width by its memory speed. If it uses DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This is worked out by multiplying the total texture units by the core speed of the chip. The better this number, the better the graphics 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 most pixels the video card could possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
