Compare any two graphics cards:
Radeon RX 460 2GB vs Radeon RX 590
IntroThe Radeon RX 460 2GB comes with core speeds of 1090 MHz on the GPU, and 1750 MHz on the 2048 MB of GDDR5 RAM. It features 896 SPUs as well as 56 TAUs and 16 Rasterization Operator Units.
Compare all that to the Radeon RX 590, which has a clock speed of 1469 MHz and a GDDR5 memory frequency of 2000 MHz. It also makes use of a 256-bit memory bus, and uses a 12 nm design. It is made up of 2304 SPUs, 144 TAUs, and 32 ROPs.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically, the Radeon RX 590 should be a lot faster than the Radeon RX 460 2GB in general. (explain)
Texel RateThe Radeon RX 590 is much (more or less 247%) faster with regards to anisotropic filtering than the Radeon RX 460 2GB. (explain)
Pixel RateThe Radeon RX 590 will be a lot (about 170%) more effective at FSAA than the Radeon RX 460 2GB, and also should be able to handle higher 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.
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: Memory bandwidth is the maximum amount of data (measured in MB per second) that can be transported past the external memory interface within a second. The number is worked out by multiplying the bus width by the speed of its memory. If it uses DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better 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 number of texture map elements (texels) that are applied in one second. This figure is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.
Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
