Intel Lakefield “Hybrid CPU” Tested: Dismal Performance w/ Lower than Spec Boost

Notebookcheck got an opportunity to try out Samsung’s Galaxy Book S, featuring the Lakefield “hybrid SoC” and the results aren’t good. As per Intel, these 10nm Lakefield processors bring ‘12% higher single-threaded compute-intensive application performance’ compared to Amber Lake Y. As far as GPU performance goes, Intel promises a 1.7x higher performance with L16G7 compared to i7-8500Y (Amber Lake). The actuality seems rather grim for Team Blue.

The piece tested by Notebookcheck shows a single-threaded performance deficit of 67% slower compared to Amber Lake. The reviewer claims this is due to the variable clock speed which hovers around 2.4GHz. The advertised boost of 3GHz was simply not witnessed. This could be due to Intel’s 10nm node which is known to suffer from lower than expected boost clocks. Or it could simply be a firmware issue, can’t say for sure this early.

In the above Cinebench single-threaded benchmark, you can see that the high-performance Sunny Cove core kicks in for a short interval after which the smaller Tremont cores juggle the workload. This is most likely due to the higher power draw of the former and the value of PL2 being exceeded here.

In the multi-core CB test, the Sunny Cove core mostly stays idle, with a sharp spike in the middle. It’s mostly just the Tremont cores handling the workload and that’s as expected. However, the lower clocks prevent them from reaching marketed levels of performance.

The graphics performance isn’t anywhere near-impressive either. The 64EU Gen11 GPU fails to match up to the 32EU Gen11 iGPU featured on the Ice Lake based Core i3-1035G1. It even lags behind the Gen 9.5 based UHD Graphics 620 found on the Core i5-10210U (Comet Lake-U).
