The Intel Core i7-12700H dispatches the AMD Ryzen 9 5900HX in performance and efficiency benchmarks
While we have already reviewed the Intel Core i9-12900HK in the MSI GE76 Raider, we are yet to put the Core i7-12700H through its paces. The Core i9-12900HK's first-class performance implied that Intel was onto a winner with the Core i7-12700H though, which Hardware Unboxed has demonstrated in its latest video.
To recap, the Core i7-12700H has the same 6 energy-efficient cores than the Core i9-12900HK, along with its 8 performance cores. As such, the 14-core processor has 20 threads, with Intel Hyper-Threading only active on the Core i7-12700H's performance cores. Additionally, the Core i7-12700H has a 45 W TDP, which increases to 115 W under PL2.
Nonetheless, the Core i7-12700H delivers greater performance per watt than the AMD Ryzen 9 5900HX, Ryzen 7 5800H, Core i7-11800H and Core i7-10870H. Also, the Core i7-12700H basically matches the M1 Pro's performance per watt at 40 W. Moreover, Hardware Unboxed shows that the Core i7-12700H scales significantly better than its AMD Ryzen 5000 counterparts at higher power limits, where the Ryzen 9 5900HX and Ryzen 7 5800H trail off.
Correspondingly, the Core i7-12700H needs a decent cooling system to get the best from it. Hardware Unboxed notes that it is comparing the Alder Lake processor against last-generation competitors, M1 Pro excluded. Presumably, the Ryzen 6000 series will close the gap between the Core i7-12700H and the Ryzen 7 5800H. Still, the YouTube channel expects Intel to maintain a lead over AMD for this generation of processors.
Incidentally, the M1 Pro operates more efficiently than the Core i7-12700H in specific workloads, such as 7zip extractions. In fact, the M1 Pro matches the Core i7-12700H's performance in this regard, but while consuming half the power that the Core i7-12700H does. Hardware Unboxed also covers Alder Lake's gaming performance, although it is worth noting that none of the other benchmarked devices contain an NVIDIA GeForce RTX 3080 Ti GPU.
