The branching and the scripting language hit was unexpected. It slows single-threaded programs the most. That means this definitely wasn't caused by an out-of-spec high power limit set on the motherboards. So the common theory was wrong.
Games seem to be unaffected. There was suspicion regarding the timing of this patch and AMD's new processors coming out. That now seems to be unfounded, with only a minimal effect on consumer applications.

No, low thread workloads draw more volts than high thread workloads. This is easily observable using anything that measures CPU voltages. Single threaded use cases seeing more impact, if any, is completely within expectations. That said, Intel said performance drops should be negligible if any. I haven't updated my system yet since ASUS's releases are currently marked as beta, but I don't expect there to be notable performance drops either. Granted, my 14700K in my daily driver has been working perfectly fine since I bought it and so have all the other Raptor Lake machines I care for.
- BearOso 2y agoEarlier reports believed the motherboard was setting the total power limit too high, like 300W. That would have affected multithreaded workloads. The voltage spiking during mispredicted vdroop was actually the cause.
