According to new information from reasonably reliable Intel leaker Jaykihn, Intel's upcoming Nova Lake desktop CPUs will have an unusual limiter applied. He claims that the next-gen desktop parts from Intel will "universally limit the maximum core frequency to 5.1 GHz when above 90°C." That doesn't mean the parts will top out at 5.1 GHz, which would be disastrous, but it does mean that you're going to need some darn good cooling to reach high clock rates on Nova Lake desktop CPUs.
- Intel VP Robert Hallock sets Nova Lake expectations, teases return to Raptor Lake for DDR4 platforms
- CPU scaling with DLSS
- Intel's one-two punch plan in desktop CPUs is taking shape
- Benchmarking AMD's BC-250, offering Steam Machine-like performance at half the price
- AMD splits Zen 7 into three EPYC families for 2028 and starts selling server CPUs by the agent
Let's be clear about what he's saying. He's not saying that Nova Lake CPUs can't go above 5.1 GHz. He's also not saying that Nova Lake CPUs have their thermal limit at 90°C. While Jaykihn doesn't provide any clock rate information, he does imply that the chips will go above that, possibly quite significantly, as long as the thermals are kept in check, and he does say that the "Tjmax" value of Nova Lake is 100°C. Notably, that's a drop from 105°C in Arrow Lake, although prior-gen Raptor Lake CPUs had the same 100°C peak.
Alike TJMax, this temperature threshold cannot be shifted upwards.
