New benchmarks of an RX Vega engineering sample video card have surfaced. There have been quite a few benchmarks for this card already, which manifests with the 687F:C1 identifier. The new, GTX 1080 beating benchmark (Gaming X version, so a factory overclocked one) comes courtesy of 3D Mark 11, with the 687F:C1 RX Vega delivering 31,873 points in its latest appearance (versus 27,890 in its first). Since the clock speed of the 687F:C1 RX Vega has remained the same throughout this benchmark history, I think it's fair to say these improvements have come out purely at the behest of driver and/or firmware level performance improvements.
