Anandtech did a deep dive on Intel's new Lakefield CPU with 1 big core (Sunny Cove) and 4 small cores (Tremont) design. It's interesting as the big.Little design is what intel could be using going forward to combat AMD according to rumours.
For now though, there are quite a few issues but still a good read.
"Our recommendation, for anyone wanting to test the performance of that single Sunny Cove core, is to implement an affinity mask on the software being used. If the software only knows that one core exists, then it can only run on that core. This is how we suspect that Intel achieved the single core performance gains in benchmarks like SPEC2006. However Intel has more tools at its disposal – there’s a chance that the scheduler for these systems might ignore affinity masks in order to maintain a thermal balance in the design. We must wait until we get a sample in for ourselves.
To a certain extent we see this in the Cinebench R15 multi-threaded test. With a standard 5 thread processor, if you run a standard nT test, we expect it to fill all the cores to give the best performance. In Notebookcheck’s article, we can see that the scheduler has evicted the workload from the big core. This is likely due to power/thermal hotspot reasons.
In the task manager on the right, we see the first four Atom cores running at 100% while in the multi-threaded test, while the large Sunny Cove core is relatively idle. Note that the CPU is running at 1.9 GHz, and not the 2.8 GHz that Intel has promoted is the all-core turbo for this product.
But the bottom line is that in most cases, expect Lakefield to perform similar to four Atom cores, just above Goldmont Plus, and not like any of the Skylake/Ice Lake Core products and its derivatives."
