Compare any two graphics cards:
Radeon R9 M385X vs Radeon RX Vega 56
IntroThe Radeon R9 M385X features a GPU clock speed of 1100 MHz, and the 4096 MB of GDDR5 memory is set to run at 1500 MHz through a 128-bit bus. It also is comprised of 896 SPUs, 56 Texture Address Units, and 16 ROPs.
Compare those specifications to the Radeon RX Vega 56, which features GPU core speed of 1156 MHz, and 8192 MB of HBM2 memory set to run at 1600 MHz through a 2048-bit bus. It also is comprised of 3584 SPUs, 224 TAUs, and 64 Raster Operation Units.
Power Usage and Theoretical Benchmarks
Theoretically speaking, the Radeon RX Vega 56 should perform much faster than the Radeon R9 M385X overall. (explain)
Texel RateThe Radeon RX Vega 56 is quite a bit (more or less 320%) better at texture filtering than the Radeon R9 M385X. (explain)
Pixel RateIf running with a high screen resolution is important to you, then the Radeon RX Vega 56 is the winner, by far. (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 (in units of megabytes per second) that can be transported across the external memory interface in one second. It is calculated by multiplying the card's bus width by its memory speed. If the card has DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This number is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.
Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units 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 rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
