At 45W, the multi-threaded performance of the chip is well sustainable and reasonable for this kind of device form-factor and cooling solution, but here it needs to be put into context,

particularly against the nearest competition,
which is AMD’s Ryzen 9 5980HS. In our benchmarks, both the Core i9-11980HK and the Ryzen 9 5980HS battle it out, sometimes with the Intel chip coming ahead, sometimes with the AMD chip leading the results.
The issue with this comparison though is that we’re comparing a 45W chip(intel) vs a 35W chip(amd),
and more often in compute heavy workloads such as rendering or encoding, the AMD chip comes ahead even though it has a lower TDP.
