Compare any two graphics cards:
Radeon HD 5870 vs Radeon RX 560
IntroThe Radeon HD 5870 uses a 40 nm design. AMD has clocked the core speed at 850 MHz. The GDDR5 RAM runs at a frequency of 1200 MHz on this specific card. It features 1600(320x5) SPUs along with 80 Texture Address Units and 32 Rasterization Operator Units.
Compare all that to the Radeon RX 560, which features a GPU core clock speed of 1175 MHz, and 4096 MB of GDDR5 RAM set to run at 7000 MHz through a 128-bit bus. It also features 1024 SPUs, 64 TAUs, and 16 Raster Operation Units.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically speaking, the Radeon HD 5870 should be 34% faster than the Radeon RX 560 overall, because of its higher bandwidth. (explain)
Texel RateThe Radeon RX 560 should be a small bit (about 11%) more effective at AF than the Radeon HD 5870. (explain)
Pixel RateThe Radeon HD 5870 is quite a bit (about 45%) more effective at FSAA than the Radeon RX 560, and also will be capable of handling higher 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 data (measured in megabytes per second) that can be transferred across the external memory interface in one second. It is worked out by multiplying the interface width by the speed of its memory. In the case of DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total amount 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 in one second.
Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
