About the Intel Core i9-11900H CPU
The Intel Core i9-11900H is an end-of-life 8-core (16-thread) processor built for the mobile CPU market. It launched in Q2 2021 with a suggested retail price of $546. It is part of Intel's Core i9 lineup, which is based on the Tiger Lake-H microarchitecture. The i9-11900H is compatible with Intel BGA 1787 motherboards and is fabricated on Intel's 10 nm manufacturing process. It features the UHD Graphics 750 integrated graphics solution.
Memory and Cache
The Core i9-11900H supports DDR4 memory and features a dual-channel memory controller, allowing it to utilize 2 memory modules simultaneously. In terms of cache, the Core i9-11900H 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 i9-11900H features 8 total cores which can process 16 threads simultaneously. The multi-threading capability allows the CPU to execute multiple computational tasks in parallel. The base clock speed of the CPU is 2.1 GHz, and it can boost up to 4.9 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 i9-11900H includes an integrated graphics solution called UHD Graphics 750. 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 i9-11900H has the 84th best 3DMark 11 Performance Physics score among the 721 benchmarked CPUs in our database. It achieves 50.51% of the performance of the best benchmarked CPU, the AMD Ryzen 9 7950X3D. Its 18,686 score and $546 launch price (MSRP) gives it a performance per dollar of 34.22. This is the 104th best in value for the 3DMark 11 Perf. Physics benchmark.
About the Intel Core i7-3940XM CPU
The Intel Core i7-3940XM is an end-of-life 4-core (8-thread) processor built for the mobile CPU market. It launched in Q3 2012.
