VideoCardz comments the performance of the Vega card with device ID '687F:C1' has increased by about 15 percent versus older benchmark results from ~3 months ago. However, the site also notes the highest score achieved by the 687F:C1 is from an overclocked chip:
The highest score the 687F:C1 has achieved is an overclocked chip. 3DMark11 does not recognize unreleased overclocked graphics cards very well. The good news is that this puts RX Vega above overclocked GTX 1070, bad news, it might still be slower than overclocked GTX 1080. I guess time will verify those results.The results are in-line with what was seen last week from the Vega Frontier Edition. The overclocked RX Vega is faster than an overclocked GeForce GTX 1070 but somewhat slower than an overclocked GeForce GTX 1080.
