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 Intel Core Ultra 7 155H CPU
The Intel Core Ultra 7 155H is a 16-core (22-thread) processor built for the mobile CPU market. It launched in Q4 2023. It is part of Intel's Ultra 7 lineup, which is based on the Meteor Lake microarchitecture. The Ultra 7 155H is compatible with Intel BGA 2049 motherboards and is fabricated on Intel's 7 nm manufacturing process. It features the Arc Xe-LPG 128EU integrated graphics solution.
Memory and Cache
The Core Ultra 7 155H supports DDR5 memory and features a dual-channel memory controller, allowing it to utilize 2 memory modules simultaneously. In terms of cache, the Core Ultra 7 155H has multiple levels of cache. Its L1 cache, which is the smallest and fastest, is 112 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 24 MB.
Cores and Clock Speeds
The Core Ultra 7 155H features 16 total cores which can process 22 threads simultaneously. The multi-threading capability allows the CPU to execute multiple computational tasks in parallel. The 16 cores consist of 6 P-Cores and 10 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 3.8 GHz, and it can boost up to 4.8 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 Ultra 7 155H includes an integrated graphics solution called Arc Xe-LPG 128EU. 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 Ultra 7 155H has the 68th best 3DMark 11 Performance Physics score among the 721 benchmarked CPUs in our database. It achieves 55.72% of the performance of the best benchmarked CPU, the AMD Ryzen 9 7950X3D.
