Compare any two graphics cards:
Radeon RX 580 vs Radeon RX 590
IntroThe Radeon RX 580 has a GPU core speed of 1257 MHz, and the 8192 MB of GDDR5 memory runs at 2000 MHz through a 256-bit bus. It also features 2304 SPUs, 144 TAUs, and 32 ROPs.
Compare those specs to the Radeon RX 590, which uses a 12 nm design. AMD has clocked the core frequency at 1469 MHz. The GDDR5 RAM works at a frequency of 2000 MHz on this model. It features 2304 SPUs as well as 144 Texture Address Units and 32 ROPs.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Both cards have the exact same bandwidth, so in theory they should have the same performance. (explain)
Texel RateThe Radeon RX 590 is a small bit (about 17%) more effective at texture filtering than the Radeon RX 580. (explain)
Pixel RateThe Radeon RX 590 should be a bit (more or less 17%) faster with regards to FSAA than the Radeon RX 580, and also will be able to handle higher screen resolutions without losing too much performance. (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.
Please note that the price comparisons are based on search keywords - sometimes it might show cards with very similar names that are not exactly the same as the one chosen in the comparison. We do try to filter out the wrong results as best we can, though.
Memory Bandwidth: Bandwidth is the maximum amount of information (counted in MB per second) that can be transferred across the external memory interface within a second. The number is calculated by multiplying the interface width by its memory clock speed. If the card has DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, 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 amount of texture map elements (texels) that are applied per second. This is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.
Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
