One factor that turned obvious as I noticed some outcomes that barely favored working with an influence restrict, vs. with none limits: it’s attainable that our Core i9-13900K, when working with none limits and infrequently peaking above 300 W, was thermally restricted. Stunning, I do know. I exploit a 360 mm AiO with the followers and pump at 100% always, however I believe customized cooling can be required to get rid of attainable thermal efficiency limitations.
I got here to this fairly apparent conclusion when contemplating that, whether it is certainly attainable to realize larger efficiency in something by decreasing the ability restrict, there should be some thermal throttling at play – or not less than much less opportunistic boosting given the out there thermal headroom in a given second.
I believe it’s protected to say that, apart from the slower all-core efficiency when energy restricted, there appears to be little motive to run at limitless energy on a regular basis. An influence restrict of 125 W offered the identical gaming efficiency with a strong GPU, and taking issues as much as 241 W restored all however just a few proportion factors of the limitless efficiency stage in multi-core workloads.
Intel was very profitable with the Core i9-13900K launch, with charts throughout YouTube and web sites like this showcasing Intel’s return to the highest of the charts in lots of situations. However after the benchmarking is finished, and particularly should you simply need to play video games, I believe it’s okay to show down the ability. You in all probability received’t even discover – apart from, you realize, decrease temps and a less expensive energy invoice subsequent month.
