Summary
About the Intel Core Ultra X9 388H CPU
The Intel Core Ultra X9 388H is a 16-core (16-thread) processor built for the mobile CPU market. It launched in Q1 2026. It is part of Intel's Ultra X9 lineup, which is based on the Panther Lake-H microarchitecture. The Ultra X9 388H is compatible with Intel BGA 2540 motherboards and is fabricated on Intel's 3 nm manufacturing process. It features the Arc B390 integrated graphics solution.
Memory and Cache
The Core Ultra X9 388H supports DDR5 memory and features a dual-channel memory controller, allowing it to utilize 2 memory modules simultaneously. In terms of cache, the Core Ultra X9 388H has multiple levels of cache. Its L1 cache, which is the smallest and fastest, is 192 KB in size, providing rapid access to crucial instructions. Its L2 cache, at 2.5 MB, is larger but slower than the L1. Its L3 cache, a shared resource among the CPU's cores, has a capacity of 18 MB.
Cores and Clock Speeds
The Core Ultra X9 388H features 16 total cores which can process 16 threads simultaneously. The multi-threading capability allows the CPU to execute multiple computational tasks in parallel. The 16 cores consist of 4 P-Cores and 12 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 2.1 GHz, and it can boost up to 5.1 GHz under heavy workloads. Higher clock speeds result in better performance for the same microarchitecture. The multiplier is locked, making it incapable of overclocking for pushing performance further.
Integrated Graphics
The Core Ultra X9 388H includes an integrated graphics solution called Arc B390. This graphics processor is directly integrated into the CPU and is not as powerful as a dedicated graphics card. While integrated graphics can handle basic tasks like web browsing and office applications, it is not suitable for more demanding activities such as gaming or video editing, where a dedicated graphics card offers superior performance.
