Samsung Galaxy Book S (Intel Lakefield 5C/5T CPU) checked
Intel’s Lakefield CPUs are rather fascinating processors. They are a very first for Intel in a number of methods. The tiny 12 x 12 x 1mm bundles are Intel’s very first for customers to take advantage of Foveros 3D-stacking tech, and the other significant very first is that the core types are blended to provide a ‘hybrid CPU’. Constructed on 10nm, the very first Intel Lakefield CPUs come packaging 5C/5T. The ‘hybrid’ from the description describes Intel’s take on big.LITTLE – as it has consisted of a single efficiency scalable 10nm ‘Warm Cove’ core alongside 4 power-efficient ‘Tremont’ cores. In theory this needs to provide the best-of-both-worlds, within the power envelope given, with Sunny Cove used for nippy single core operations, and the Tremont cores helping to shoulder multi-threaded jobs.
Last month, the Samsung Galaxy Book S introduced in an Intel Lakefield CPU variation. It had formerly been offered powered by the Qualcomm Snapdragon 8cx running Windows 10. Earlier this month, after Samsung’s statement for some reason, Intel formally introduced its Lakefield 3D packaged hybrid processors. The Samsung Galaxy Book S with Lakefield CPU is only just beginning to become offered however, and the only other Lakefield gadget we understand of with a confirmed release window is the Lenovo’s ThinkPad X1 Fold, coming later on in 2020.
Laptop-centric tech site NotebookCheck is one of the first to get their hands on a Samsung Galaxy Book S (Intel) and has quickly run it through a number of tests to examine its abilities. To cut a long story short, the website is rather underwhelmed by Intel’s answer to the Snapdragon 8cx, however isn’t rather sure if it’s the hardware or software application to blame.
The processor used by the Intel version of the Samsung Galaxy Book S is a Core i5-L16G7. You can have a look at the full authorities specifications on the Ark. In short, it has the previously mentioned CPU core configuration performing at base/boost of 1.4/ 3.0 GHz, with 4MB cache, in a 7W envelope. It supports a max 8GB of RAM, with 34GB/s bandwidth, and Gen. 11 Intel UHD Graphics (Iris Plus Graphics G7) with 64 Execution Units are onboard. NotebookCheck highlights that the graphics cores run much slower on this 7W part than on 15W designs.
So, how does the very first Lakefield processor tested carry out? In single core mode it is unexpected to hear that the Lakefield chip “even falls back the old Amber Lake dual-core m3-8100Y”. The Arm-based SD8cx chip beats it convincingly in Geekbench. It is thought the primary offender is the Lakefield boost speed never ever coming up to the marketed 3.0 GHz, maxing out at about 2.4 GHz for NotebookCheck.
Web browser performance wasn’t very motivating either, with the Lakefield sitting not very comfortably above Pentium and Celeron CPUs on the whole – not much better than the SD8cx. Lastly, we cautioned about the GPU clocks above and that lack of power/ low clock speeds is reflected in an uninspiring proving in 3DMark and in video games like Dota 2.
In conclusion, according to our heading, the Lakefield CPU isn’t going to rock your world but it does manage to complete against a model equipped with the SD8cx. The price is the very same it seems, but NotebookCheck hasn’t had an appropriate look at battery life yet. Another fascinating point raised by a NotebookCheck reader is that the present variation of Windows 10 doesn’t support Lakefield scheduling, so it is running as a quad-core Atom part in the tests, as the OS requires a spot or upgrade to make full usage of this CPU. If this is the case it is quite an oversight by Samsung, Intel and/or Microsoft. I’m uncertain if the Task Manager/ Cinebench composite shots, as below, reveal this issue.
