Geekbench 5 results of the Intel Lakefield Core i5-L16G7 5-core 5-thread processor have surfaced indicating good benefits in single-core over a Core i5-L15G7. However, the score also indicates that the small Tremont cores may hinder overall multi-core performance.

Previously, we reported about an Intel Lakefield Core i5-L16G7 making its presence felt on UserBenchmark and 3DMark Fire Strike. Last week, the Core i5-L16G7 has once again surfaced online this time on Geekbench 5.

Spotted by known leakster TUM_APISAK, Core i5-L16G7 was shown running on a Samsung 767XCL notebook running Windows 10 Pro. The Core i5-L16G7 is shown to be a 5-core 5-thread processor having a base clock of 1.38 GHz and a boost clock of 2.95 GHz. The Lakefield Core i5-L16G7 CPU has 4 MB L3 cache and is paired with 8 GB RAM, which resulted in scores of 868 for single-core and 1,656 for multi-core. 

Comparing this with the scores posted by the Core i5-L15G7 previously, we see that the L16G7 offers a 19.7% increase in single-thread performance and just a 5.7% uplift in multi-core scores. At this point, the primary difference between these two SKUs seems to be only with respect to the L2 cache with the L15G7 reporting 5x more L2 cache than the L16G7. Also, the L15G7's scores seem to have been recorded in a Hyper-V virtual machine of the Windows Core OS, which could probably contribute to its lower single-core scores. The lower multi-core scores could be attributed to the slower four Tremont cores in the package, which may be common to both these SKUs.

Intel first demonstrated the Lakefield architecture last year, but we haven't seen many of those chips in the wild yet. Lakefield will use the Foveros 3D stacking chiplet architecture and will implement an ARM-esque big.LITTLE type of setup with a 10nm Sunny Cove core and four Tremont cores. These Lakefield CPUs will integrate Gen11 graphics and are expected to feature a TDP between 5 W and 7 W for use in devices such as the Microsoft Surface Go.

I am a cell and molecular biologist and computers have been an integral part of my life ever since I laid my hands on my first PC which was based on an Intel Celeron 266 MHz processor, 16 MB RAM and a modest 2 GB hard disk. Since then, I’ve seen my passion for technology evolve with the times. From traditional floppy based storage and running DOS commands for every other task, to the connected cloud and shared social experiences we take for granted today, I consider myself fortunate to have witnessed a sea change in the technology landscape. I honestly feel that the best is yet to come, when things like AI and cloud computing mature further. When I am not out finding the next big cure for cancer, I read and write about a lot of technology related stuff or go about ripping and re-assembling PCs and laptops.
