Tom's Hardware came across leaked performance results of the Intel Core i5-L15G7 in a Geekbench 5 submission. This Lakefield-based processor is a five-core model, it has four Tremont-based cores and one Sunny Cove core, similar to ARM's big.LITTLE design. Lakefield is made using Intel' Foveros packaging technology.

Expected to have a TDP in the 5W to 7W range, Lakefield will compete against chips like the Qualcomm Snapdragon. The Core i5-L15G7 seems to have a 1.38GHz base clock and a 2.95GHz Boost, presumably this is the frequency of the Sunny Cove core. The benchmark entry also reveals the chip seems to have 1.5MB L2 and 4MB L3 cache.

In terms of single-core performance, the Core i5-L15G7 sample scored 3.1 percent better than the Qualcomm Snapdragon 8cx. However, in terms of multi-threaded performance the engineering sample is still far behind:
However, the Core i5-L15G7's multi-threaded performance is no match for Qualcomm's more recent offerings, such as the Snapdragon 8cx that's inside the Samsung Galaxy Book S. For reference, the Snapdragon 8cx rocks eight Kryo 495 cores, four clocked at 2.84 GHz and the remaining at 1.8 GHz. The Samsung Galaxy Book S puts up single-core and multi-core scores of 703 points and 2,770 points. While the Core i5-L15G7 maintains 3.1% single-core lead over the Snapdragon 8cx, Qualcomm's chip ultimately offers up to 76.9% higher performance in multi-threaded workloads.
Lakefield is expected to hit the market later this year.
