Mixed results from first Intel Lakefield Core i5-L16G7 test

Tech site NotebookCheck has been able to run some tests on a Samsung Galaxy Book S with the Intel Core i5-L16G7 "Lakefield" processor. This chip uses a big.LITTLE-like design with one big Sunny Cove core and four low-power Tremont cores. Intel claims the chip offers 12 percent higher single-threaded performance than its Amber Lake-Y processors but the test from NotebookCheck revealed something different. In tests the single-threaded performance is sometimes significantly lower than the "Amber Lake-Y" Core i7-8500Y processor. Part of this seems to be caused by the fact that the CPU of the test system never hit the promised 3.0Ghz Boost, the clock never went higher than 2.4GHz according to the tester.
Intel wants its Lakefield hybrid processor to be an alternative for the ARM processors. Based on our first tests, this could works, because the initial consumption measurements are low and the graphics performance is good considering the low TDP. The raw CPU performance, especially when you only stress one core, though, requires some fine-tuning. We cannot confirm the advertised maximum clock of 3.0 GHz for the faster Sunny Cove processor in our sample of the Galaxy Book S. We will also try to find out how the load is distributed among the cores. The subjective performance impression is good so far, we did not notice any delays or or hiccups.
More tests will be needed to get the full picture. While the chip performs poorly in Cinebench R15 single-threaded, it does slightly beat the Core i7-8500Y processor in multi-threaded Cinebench R15. The tester also notes that battery life seems to be really good, but he hasn't really tested it yet.
