About the Intel Core i7-12800HX CPU
The Intel Core i7-12800HX is a 16-core (24-thread) processor built for the mobile CPU market. It launched in Q2 2022 with a suggested retail price of $457. It is part of Intel's Core i7 lineup, which is based on the Alder Lake-HX microarchitecture. The i7-12800HX is compatible with Intel BGA 1964 motherboards and is fabricated on Intel's 10 nm manufacturing process. It features the UHD Graphics 770 integrated graphics solution.
Memory and Cache
The Core i7-12800HX supports DDR4-3200, DDR5-4800 memory and features a dual-channel memory controller, allowing it to utilize 2 memory modules simultaneously. In terms of cache, the Core i7-12800HX has multiple levels of cache. Its L1 cache, which is the smallest and fastest, is 80 KB in size, providing rapid access to crucial instructions. Its L2 cache, at 1.25 MB, is larger but slower than the L1. Its L3 cache, a shared resource among the CPU's cores, has a capacity of 25 MB.
Cores and Clock Speeds
The Core i7-12800HX features 16 total cores which can process 24 threads simultaneously. The multi-threading capability allows the CPU to execute multiple computational tasks in parallel. The 16 cores consist of 8 P-Cores and 8 E-Cores. P-Cores are designed for high-performance tasks and E-Cores are intended for efficiency and lighter tasks. The base clock speed of the CPU is 2000.0 MHz, and it can boost up to 4.8 GHz under heavy workloads. Higher clock speeds result in better performance for the same microarchitecture. The multiplier is unlocked, enabling overclocking for those seeking to push the CPU's performance further.
Integrated Graphics
The Core i7-12800HX includes an integrated graphics solution called UHD Graphics 770. This graphics processor is directly integrated into the CPU and is not as powerful as a dedicated graphics card.
