CPU Comparison
Core i7-12800H vs Core i7-12800HX
A side-by-side comparison of specs, performance and value. The Intel Core i7-12800H is a premium mobile processor launched in early 2022 under the Alder Lake-H umbrella. Fabricated on Intel's 10nm process, it employs a robust hybrid architecture with 6 performance cores and 8 efficiency cores, totaling 14 cores and 20 threads. This configuration makes it exceptionally well-suited for high-end gaming laptops and thin-and-light creator machines. The CPU boasts a base clock of 2.4 GHz and a maximum turbo frequency of 4.8 GHz. It features a generous 24 MB L3 cache and supports both DDR4 and DDR5 memory architectures. With a base TDP of 45W and a maximum turbo power of 115W, it strikes a fine balance between raw throughput and mobile power constraints. Unlike the 12650H, the 12800H integrates Intel Iris Xe Graphics with 96 Execution Units, providing superior graphical capability.
The Bottom Line
