AMD’s fifth-generation desktop Ryzen CPUs aren’t even out but, however they’re already setting efficiency information. In case you missed it, verify our put up yesterday the place we talked about some loopy overclocking and insane benchmark outcomes from AMD’s pre-release processors. These outcomes happened with “normal” water-cooling, although. What can the chip do beneath liquid nitrogen? Because it seems, at the very least 7.25 GHz.
That pace is one in all two overclocking outcomes introduced right now by veteran benchmark-watcher APISAK (@TUM_APISAK on Twitter.) Whereas he did not hyperlink the CPU-Z validation for both consequence, we have no actual cause to doubt him at his phrases. This 7.25 GHz consequence was taken with all 16 cores energetic, however the clock was solely reached on a single core.
Nonetheless, that is very spectacular for a contemporary CPU structure. The world-record clock pace continues to be The Stilt’s 8,722 MHz consequence from an AMD FX-8370, however we have little doubt that Zen 4 at 7.25 GHz would completely bloodbath the poor outdated Vishera chip regardless of the 1.5 GHz clock price disparity.
Even placing apart that it requires unique and costly LN2 cooling to attain, a single-core clock price is not significantly sensible in any case, in fact. That is why the opposite result’s arguably extra spectacular. Probably utilizing an analogous cooling setup (and a barely toasty 1.465v core voltage), overclockers managed to hit a cool 6.5 GHz throughout all 16 cores of the Ryzen 9 7950X.
These outcomes are spectacular, however it will likely be attention-grabbing to see what the sensible limits of AMD’s silicon are after the CPU launches. Intel’s already promised a Raptor Lake SKU that does 6 GHz out of the field, and overclockers have pushed it to eight GHz beneath excessive cooling. With the CPUs working neck-and-neck in IPC, that might current an enormous efficiency benefit to Intel’s chips—assuming you possibly can deal with the ability, warmth, and noise required by such a chip.
