About the AMD Ryzen 9 5900HX CPU

The AMD Ryzen 9 5900HX is a 8-core (16-thread) processor built for the mobile CPU market. It launched in Q1 2021. It is part of AMD's Ryzen 9 lineup, which is based on the Zen 3 microarchitecture. The 5900HX is compatible with AMD Socket FP6 motherboards and is fabricated on TSMC's 7 nm manufacturing process. It features the Radeon Vega 8 integrated graphics solution.

Memory and Cache

The Ryzen 9 5900HX supports DDR4 memory and features a dual-channel memory controller, allowing it to utilize 2 memory modules simultaneously. In terms of cache, the Ryzen 9 5900HX 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 512 KB, 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 9 5900HX 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 3.3 GHz, and it can boost up to 4.6 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 Ryzen 9 5900HX includes an integrated graphics solution called Radeon Vega 8. 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 Ryzen 9 5900HX has the 106th best 3DMark 11 Performance Physics score among the 721 benchmarked CPUs in our database. It achieves 45.87% of the performance of the best benchmarked CPU, the AMD Ryzen 9 7950X3D.

About the AMD Ryzen 5 7645HX CPU

The AMD Ryzen 5 7645HX is a 6-core (12-thread) processor built for the mobile CPU market. It launched in Q1 2023. It is part of AMD's Ryzen 5 lineup, which is based on the Zen 4 microarchitecture. The 7645HX 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 5 7645HX supports DDR5 memory and features a dual-channel memory controller, allowing it to utilize 2 memory modules simultaneously. In terms of cache, the Ryzen 5 7645HX 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 32 MB.

Cores and Clock Speeds

The Ryzen 5 7645HX features 6 total cores which can process 12 threads simultaneously. The multi-threading capability allows the CPU to execute multiple computational tasks in parallel. The base clock speed of the CPU is 4.0 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 Ryzen 5 7645HX includes an integrated graphics solution called Radeon 610M. 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 Ryzen 5 7645HX has the 65th best 3DMark 11 Performance Physics score among the 721 benchmarked CPUs in our database. It achieves 56.03% of the performance of the best benchmarked CPU, the AMD Ryzen 9 7950X3D.
