CPU Comparison
Core i7-12800HX vs Intel Core i7-14650HX
A side-by-side comparison of specs, performance and value. The Intel Core i7-12800HX is a flagship-tier mobile processor released in May 2022 as part of the Alder Lake-HX family. Built on Intel's 10nm process, it pushes mobile computing to desktop replacement levels by featuring 16 cores (8 P-cores and 8 E-cores) and 24 threads. This massive core count is borrowed directly from Intel's desktop silicon, offering unparalleled multi-threaded performance for a mobile chip. The processor operates at a 2.0 GHz base clock and boosts up to 4.8 GHz. It includes 25 MB of L3 cache and supports both DDR4 and DDR5 memory. With a base TDP of 55W and a maximum turbo power of 157W, the 12800HX demands robust cooling solutions. It also features an unlocked multiplier for enthusiast overclocking, 20 PCIe 5.0 lanes, and Intel UHD Graphics 770.
