Vega Thread

The primary takeaway is that CUs are far less impacting to performance on Vega than raw clocks. In some tests, we didn’t even have to bypass the power limit in order to surpass stock V64 – but doing so helps keep up as V64 becomes overclocked, something we’ll look into more later. A 50% offset and modest 9% / 980MHz OC gets us to V64 performance levels. In some games, the extra 50% power (going to 100% offset, increasing current to 30-33A at 12.3V) pushes us toward and into double-digit percentage gains over the V56 OC, while other games give us ~7-8%. It just depends on the game, turns out, but results are promising in some instances.

One thing we’ve learned for sure is that V64 is hardly worth a consideration. Fifteen to twenty minutes overclocking even a reference V56 – let alone a partner model – gets us to V64 stock performance. The power mods just make it that much better. They’re probably not worth it in 95% of use cases, but the fact that AMD provided an insanely over-built VRM really does invite the play. Might as well make use of it.
