Intel’s 12th Gen mobile CPUs are slated to launch in the first half of 2022, following the release of the Alder Lake-S desktop SKUs earlier this month. We’ve already seen leaks of some of the Alder Lake-P processors over the last month. The Core i9-12900H and 12900HK were found to be a fair bit faster than their preceding 10nm and 14nm counterparts. The latest leak includes performance figures of the Core i7-12700H (Geekbench via @TumApisak).
The Core i7-12700H is a 14 core processor, much like the Core i9-12900H and 12900HK with 24MB of L3 cache. The boost clock has been scaled down to 4.6GHz. The CPU consists of six performance cores (Golden Cove) and eight efficiency (Gracemont) cores. The latter will be clocked lower than the former both in terms of the base and boost clocks, with hyperthreading also being limited to the performance cores.
In terms of multi-threaded performance, we’re looking at roughly the same levels of performance as the Apple M1 Max. The Core i7-12700H is 40% faster than its predecessor (Core i7-11800H), and nearly 60% faster than the AMD Ryzen 7 5800H. Compared to the Core i9-11900HK, we’re looking at an overall uplift of 40%, much of which is the result of the additional Gracemont cores (8 cores vs 14 cores). In the end, it appears that the hybrid core architecture is working to Intel’s advantage, at least in multi-threaded workloads.
