About the Intel Core i9-13905H CPU

The Intel Core i9-13905H is a 14-core (20-thread) processor built for the mobile CPU market. It launched in Q1 2023 with a suggested retail price of $697. It is part of Intel's Core i9 lineup, which is based on the Raptor Lake-H microarchitecture. The i9-13905H is compatible with Intel BGA 1744 motherboards and is fabricated on Intel's 10 nm manufacturing process. It features the Iris Xe Graphics 96EU integrated graphics solution.

Memory and Cache

The Core i9-13905H supports DDR4-3200, DDR5-5200 memory and features a dual-channel memory controller, allowing it to utilize 2 memory modules simultaneously. In terms of cache, the Core i9-13905H 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 24 MB.

Cores and Clock Speeds

The Core i9-13905H 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 2.6 GHz, and it can boost up to 5.4 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 i9-13905H includes an integrated graphics solution called Iris Xe Graphics 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 & Value

The Core i9-13905H has the 34th best 3DMark 11 Performance Physics score among the 721 benchmarked CPUs in our database. It achieves 64.59% of the performance of the best benchmarked CPU, the AMD Ryzen 9 7950X3D. Its 23,894 score and $697 launch price (MSRP) gives it a performance per dollar of 34.28. This is the 103rd best in value for the 3DMark 11 Perf. Physics benchmark.

About the AMD Ryzen 9 7945HX3D CPU

The AMD Ryzen 9 7945HX3D is a 16-core (32-thread) processor built for the mobile CPU market. It launched in Q3 2023. It is part of AMD's Ryzen 9 lineup, which is based on the Zen 4 microarchitecture. The 7945HX3D is compatible with AMD Socket FL1 motherboards and is fabricated on TSMC's 5 nm manufacturing process. It features the Radeon 610M integrated graphics solution.

Memory and Cache

The Ryzen 9 7945HX3D supports DDR5 memory and features a dual-channel memory controller, allowing it to utilize 2 memory modules simultaneously. In terms of cache, the Ryzen 9 7945HX3D has multiple levels of cache. Its L1 cache, which is the smallest and fastest, is 64 KB in size, providing rapid access to crucial instructions. Its L2 cache, at 1 MB, is larger but slower than the L1. Its L3 cache, a shared resource among the CPU's cores, has a capacity of 128 MB.

Cores and Clock Speeds

The Ryzen 9 7945HX3D features 16 total cores which can process 32 threads simultaneously. The multi-threading capability allows the CPU to execute multiple computational tasks in parallel. The base clock speed of the CPU is 2.3 GHz, and it can boost up to 5.4 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.
