Along that vein, the performance can be bumped up by overclocking. In most games, the overclock I reached would deliver stock GTX 1080 FE performance. Not bad for AMD's latest architecture. When you compare the performance delivered by the Red Devil RX 580 to the FPS performance delivered by the Red Devil RX Vega 56, you see a significant lift in performance from Polaris to the lower spec Vega. When overclocking the card I was a little disappointed at the amount of headroom on the card, but that has been a trait of AMD ASICs over the past few generations. The factory overclock of 1500MHz was boosted to 1631MHz with actual running speeds in the 1611MHz range did boost performance.
