About the AMD Ryzen 9 7945HX CPU

The AMD Ryzen 9 7945HX is a 16-core (32-thread) processor built for the mobile CPU market. It launched in Q1 2023. It is part of AMD's Ryzen 9 lineup, which is based on the Zen 4 microarchitecture. The 7945HX 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 7945HX 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 7945HX 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 64 MB.

Cores and Clock Speeds

The Ryzen 9 7945HX 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 2.5 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.

Integrated Graphics

The Ryzen 9 7945HX 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 9 7945HX has the 25th best 3DMark 11 Performance Physics score among the 768 benchmarked CPUs in our database. It achieves 69.68% of the performance of the best benchmarked CPU, the AMD Ryzen 9 9950X.

About the AMD Sempron SI-40 CPU

The AMD Sempron SI-40 is a 1-core (1-thread) processor built for the mobile CPU market. The Sempron SI-40 is compatible with S1 motherboards.

Memory and Cache

In terms of cache, the Sempron SI-40 has multiple levels of cache. Its L1 cache, which is the smallest and fastest, is 128 KB in size, providing rapid access to crucial instructions. Its L2 cache, at 512 KB, is larger but slower than the L1.

Cores and Clock Speeds

The Sempron SI-40 is a single-core and single-threaded CPU, making it not capable of processing multiple computational tasks in parallel. The base clock speed of the CPU is 2000.0 MHz. Higher clock speeds result in higher performance for the same microarchitecture.

Integrated Graphics

The Sempron SI-40 does not include an integrated graphics solution. A dedicated graphics card will be required if you require a monitor with your computer.
