Last year, Intel announced the 10nm low-power Lakefield processors for tablets and thin laptops. And now new data on the performance of these chips has appeared – one of them has been tested in UserBenchmark.
First, recall that Lakefield processors are hybrid x86 processors built by analogy with ARM big.LITTLE chips. In this case, there is one productive core with Sunny Cove microarchitecture (like Ice Lake), and four low-power Atom Thremont cores. The first is used for demanding tasks, while the other four are used for basic tasks and allow you to save energy. The scheme is similar to single-chip smartphone platforms.

The Core i5-L16G7 processor, which has five cores and five threads, was tested in UserBenchmark, and its clock frequencies, according to the test, amounted to 1.4 / 1.75 GHz. Most likely, the test passed with some limitations, since the maximum frequency of the “large” core should reach 3.16 GHz, and the “small” – 2.5 GHz. By the way, the chip was tested in the device Samsung NP 767XCL, which is a thin laptop.

It is expected that the performance of such a processor leaves much to be desired. If we compare the test results, the Core i5-L16G7 turned out to be as much as 85% less productive than the Core i3-10110U processor, which has two cores, four threads and a frequency of up to 4.1 GHz. But, of course, the Lakefield processor consumes much less energy: the most powerful chips here have a TDP of 5-7 watts, while the aforementioned Core i3 this indicator is 15 watts.
