Compare any two graphics cards:
Radeon R9 280 vs Radeon RX 590
IntroThe Radeon R9 280 features a clock speed of 933 MHz and a GDDR5 memory speed of 1250 MHz. It also features a 384-bit memory bus, and uses a 28 nm design. It is comprised of 1792 SPUs, 112 Texture Address Units, and 32 Raster Operation Units.Compare those specifications to the Radeon RX 590, which makes use of a 12 nm design. AMD has clocked the core speed at 1469 MHz. The GDDR5 RAM works at a speed of 2000 MHz on this particular model. It features 2304 SPUs as well as 144 Texture Address Units and 32 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon RX 590 should in theory be just a bit faster than the Radeon R9 280 in general. (explain)
Texel RateThe Radeon RX 590 is a lot (approximately 102%) faster with regards to texture filtering than the Radeon R9 280. (explain)
Pixel RateThe Radeon RX 590 is quite a bit (more or less 57%) faster with regards to full screen anti-aliasing than the Radeon R9 280, and also capable of handling higher screen resolutions while still performing well. (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 information (in units of megabytes per second) that can be moved over the external memory interface in a second. The number is worked out by multiplying the card's bus width by its memory speed. If the card has DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This figure is worked out by multiplying the total number of texture units by the core speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second. Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. The number 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 filling the screen with pixels (the image). The actual pixel rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
