Earlier this week, I posted our initial review of AMD's RX Vega 56 and Vega 64, showing much of what the new cards have to offer. Due to time constraints (the cards arrived Friday morning, for a Monday unveiling), I couldn't complete all the testing I wanted. Now with a few more days with the Vega 64, I'm ready to issue a final verdict. If you're looking for more details on the underlying architecture and changes made with Vega, you can read our Vega deep dive and Vega preview, but the focus here will be specifically on the RX Vega 64 air-cooled version, how it performs, overclocking/underclocking, and more.

The RX Vega 64 comes in three flavors from AMD: the reference air-cooled card I'm reviewing, a limited edition model with a shiny blue brushed aluminum shroud that should otherwise perform the same, and the liquid-cooled variant that's currently only available via the Aqua Pack. All three cards clock the HBM2 memory at the same 945MHz base clock, but the liquid-cooled model increases the base clockspeed by 12.8 percent, and the boost clock by 8.5 percent. At most, then, the liquid card should be around 13 percent faster, but it might be more (or less) than that depending on whether you're willing to increase the default fan speeds.
