Elmnator1 uploaded some footage from AMD's PDXLAN event, where gamers could compare AMD's Radeon RX Vega with a comparable GPU from NVIDIA. Just like the event in Budapest, this was a blind test so gamers had no idea whether they were using the AMD or NVIDIA system.
The Radeon RX Vega will be officially revealed at SIGGRAPH by the end of this week but in the meantime it's hard to figure out what's going on. It seems AMD is trying to scale down expectations as the low-key Budapest and PDXLAN events don't inspire a lot of confidence.
The benchmarks and power characteristics of the Frontier Edition weren't good and that lead to a lot of speculation. While fans are waiting for hard data, AMD seems to be trying to steer the debate to a more subjective setting about which system "feels smoother" or that you can "hardly see the difference".
One of the last times AMD employed similar marketing was when they used a blind test to let gamers compare the AMD A8-3850 with the Intel Core i3-2015, both with integrated graphics. A second test consisted of a blind test that compared the Bulldozer-based AMD FX-8150 with the Intel Core i7-2700, both systems were equipped with the Radeon HD 7970. It could be just a coincidence, we should know more next week.
