About the Intel Core Ultra 9 285HX CPU

The Intel Core Ultra 9 285HX is a 24-core (24-thread) processor built for the mobile CPU market. It launched in Q1 2025. It is part of Intel's Ultra 9 lineup, which is based on the Arrow Lake-HX microarchitecture. The Ultra 9 285HX is compatible with Intel BGA 2114 motherboards and is fabricated on TSMC's 3 nm manufacturing process. It features the Arc Xe-LPG Graphics 64EU integrated graphics solution.

Memory and Cache

The Core Ultra 9 285HX 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 9 285HX 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 3 MB, is larger but slower than the L1. Its L3 cache, a shared resource among the CPU's cores, has a capacity of 36 MB.

Cores and Clock Speeds

The Core Ultra 9 285HX features 24 total cores which can process 24 threads simultaneously. The multi-threading capability allows the CPU to execute multiple computational tasks in parallel. The 24 cores consist of 8 P-Cores and 16 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 2.8 GHz, and it can boost up to 5.5 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 Ultra 9 285HX includes an integrated graphics solution called Arc Xe-LPG Graphics 64EU. 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.

Benchmark Performance

The Core Ultra 9 285HX has the 18th best 3DMark 11 Performance Physics score among the 767 benchmarked CPUs in our database. It achieves 76.34% of the performance of the best benchmarked CPU, the AMD Ryzen 9 9950X.

About the AMD Ryzen 9 9955HX3D CPU
