About the AMD Ryzen 7 7840S CPU

The AMD Ryzen 7 7840S is a 8-core (16-thread) processor built for the mobile CPU market. The 7840S is compatible with FP7 FP7r2 FP8 motherboards and is fabricated on a 4 nm manufacturing process.

Memory and Cache

In terms of cache, the Ryzen 7 7840S has multiple levels of cache. Its L1 cache, which is the smallest and fastest, is 512 KB in size, providing rapid access to crucial instructions. Its L2 cache, at 8 MB, is larger but slower than the L1. Its L3 cache, a shared resource among the CPU's cores, has a capacity of 16 MB.

Cores and Clock Speeds

The Ryzen 7 7840S 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 3800.0 MHz, and it can boost up to 5100.0 MHz under heavy workloads. Higher clock speeds result in better performance for the same microarchitecture.

Integrated Graphics

The Ryzen 7 7840S does not include an integrated graphics solution. A dedicated graphics card will be required if you require a monitor with your computer.

Benchmark Performance

The Ryzen 7 7840S has the 64th best 3DMark 11 Performance Physics score among the 720 benchmarked CPUs in our database. It achieves 56.23% 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.

Integrated Graphics

The Core i9-14900HX includes an integrated graphics solution called UHD Graphics 770. 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 i9-14900HX has the 54th best 3DMark 11 Performance Physics score among the 720 benchmarked CPUs in our database. It achieves 59.99% of the performance of the best benchmarked CPU, the AMD Ryzen 9 7950X3D.
