About the Intel Core i9-12900H CPU

The Intel Core i9-12900H is a 14-core (20-thread) processor built for the mobile CPU market. It launched in Q1 2022. It is part of Intel's Core i9 lineup, which is based on the Alder Lake-H microarchitecture. The i9-12900H is compatible with Intel BGA 1744 motherboards and is fabricated on Intel's 10 nm manufacturing process. It features the Iris Xe 96EU integrated graphics solution.

Memory and Cache

The Core i9-12900H 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 i9-12900H 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 24 MB.

Cores and Clock Speeds

The Core i9-12900H features 14 total cores which can process 20 threads simultaneously. The multi-threading capability allows the CPU to execute multiple computational tasks in parallel. The 14 cores consist of 6 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 2.5 GHz, and it can boost up to 5.0 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 i9-12900H includes an integrated graphics solution called Iris Xe 96EU. 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 i9-12900H has the 56th best 3DMark 11 Performance Physics score among the 720 benchmarked CPUs in our database. It achieves 59.73% of the performance of the best benchmarked CPU, the AMD Ryzen 9 7950X3D.

About the Intel Core i9-14900HX CPU

The Intel Core i9-14900HX is a 24-core (32-thread) processor built for the mobile CPU market. It launched in Q1 2024. It is part of Intel's Core i9 lineup, which is based on the Raptor Lake-HX Refresh microarchitecture. The i9-14900HX 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 i9-14900HX supports DDR4-3200, DDR5-5600 memory and features a dual-channel memory controller, allowing it to utilize 2 memory modules simultaneously. In terms of cache, the Core i9-14900HX 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 2 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 i9-14900HX features 24 total cores which can process 32 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 2.2 GHz, and it can boost up to 5.8 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.
