Recently, Intel officially released the codename Lakefield hybrid technology Core processor, the first use of 3D Foveros stereo package, integrated with a Sunny Cove large core, four Tremont small core, similar to ARM big. THE LITTLE CONCEPT, WHILE INTEGRATING GPU NUCLEAR DISPLAY AND OTHER MODULES, POP INTEGRATES PACKAGED MEMORY, WHILE THE OVERALL VOLUME IS ONLY 12 X 12 X 1 MM, THERMAL DESIGN POWER CONSUMPTION IS ONLY 7W, STANDBY POWER CONSUMPTION IS AS LOW AS 2.5MW.
So what is the actual performance of this five-core, five-threaded processor? NoteBookCheck recently tested a Samsung Galaxy Book S with the i5-L16G7. It’s tangled.
the i5-L16G7 CPU core frequency is 1.7-3.0GHz, with 64 units integrated in the nuclear display section, with a maximum frequency of 500MHz. This time the main test CPU performance, running is different versions of CineBench, GeekBench.
The design of a large four or five cores (no hyperthreaded) is not only the first for Intel, but also fresh for Windows systems, and assigning the right load across the cores is critical.
Five CPU cores can be seen in Windows Task Manager, but there is no clear label as which is Sunny Cove, which four is Tremont, and the fifth from the load should be Sunny Cove.
In the CineBench rendering test, the big core did not do its best, only occasionally running at full speed, the other time occupancy rate is only about 10%, and the four small cores are very hard, either continuous 100% running, or intermittent ups and downs, it seems that the core scheduling is not optimized.
To make matters worse, the big core’s acceleration frequency is simply less than the nominal 3.0GHz, up to 2.4GHz, further affecting performance, but it’s not known whether it’s an Intel Turbo algorithm problem or a Samsung notebook design problem.
As a result, the actual performance of the i5-L16G7 is poor, with both single-core and multi-core processors far less than the previous Y-Series ultra-low-voltage processors, combining only about a third of the eight-generation ultra-low-voltage Core i3-8100Y, or even less than the Pentium 5405U.
After all, while nominally five cores, when performance is really needed, it’s either four weak, low-power small cores, or only one large core with relative lying high performance.
