Compare any two graphics cards:
Radeon R9 M385X vs Radeon RX Vega 56
IntroThe Radeon R9 M385X comes with a GPU clock speed of 1100 MHz, and the 4096 MB of GDDR5 RAM runs at 1500 MHz through a 128-bit bus. It also is made up of 896 SPUs, 56 Texture Address Units, and 16 ROPs.
Compare those specs to the Radeon RX Vega 56, which features a clock frequency of 1156 MHz and a HBM2 memory speed of 1600 MHz. It also uses a 2048-bit bus, and makes use of a 14 nm design. It is made up of 3584 SPUs, 224 TAUs, and 64 Raster Operation Units.
Power Usage and Theoretical Benchmarks
The Radeon RX Vega 56, in theory, should be much faster than the Radeon R9 M385X in general. (explain)
Texel RateThe Radeon RX Vega 56 is a lot (approximately 320%) faster with regards to AF than the Radeon R9 M385X. (explain)
Pixel RateThe Radeon RX Vega 56 is much (approximately 320%) faster with regards to full screen anti-aliasing than the Radeon R9 M385X, and 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.
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 largest amount of information (measured in megabytes per second) that can be moved across 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 memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better 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 number of texture map elements (texels) that can be applied in one second. This is calculated by multiplying the total texture units of the card by the core speed of the chip. The better this number, 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 amount of pixels the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
