Vega 20 70% Faster Per Clock vs RX Vega 64 Liquid, if the Numbers Aren’t Lying
With that being said, if Vega 20 manages to deliver similar performance to the Vega 64 Liquid at 1GHz we’re looking at no less than 70% faster performance per clock, which seems absolutely bonkers. The alternative hypothesis is that Vega 20 is running at a modest but unknown boost clock speed that 3DMark is just not picking on, although we’ve never seen boost functionality operational on any of AMD’s engineering samples in the past.
The truth most likely lies somewhere in the middle. We’re no doubt looking at a very early silicon here with nowhere near final clock speeds. Vega 20 isn’t expected to begin sampling until the end of the year and won’t hit shelves until next year. So take all of this with a grain of salt in the time being, more will surely come to light in the coming weeks and months.
