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 721 benchmarked CPUs in our database. It achieves 56.23% of the performance of the best benchmarked CPU, the AMD Ryzen 9 7950X3D.
About the AMD Ryzen 9 PRO 7940HS CPU
The AMD Ryzen 9 PRO 7940HS is a 8-core (16-thread) processor built for the mobile CPU market. The PRO 7940HS is compatible with FP7, FP7r2 motherboards and is fabricated on a 4 nm manufacturing process. It features the AMD Radeon 780M integrated graphics solution.
Memory and Cache
In terms of cache, the Ryzen 9 PRO 7940HS 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 9 PRO 7940HS 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 4000.0 MHz, and it can boost up to 5200.0 MHz under heavy workloads. Higher clock speeds result in better performance for the same microarchitecture.
Integrated Graphics
The Ryzen 9 PRO 7940HS includes an integrated graphics solution called AMD Radeon 780M. 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 PRO 7940HS has the 78th best 3DMark 11 Performance Physics score among the 721 benchmarked CPUs in our database. It achieves 51.35% of the performance of the best benchmarked CPU, the AMD Ryzen 9 7950X3D.
