About the AMD Ryzen 7 7840U CPU

The AMD Ryzen 7 7840U is a 8-core (16-thread) processor built for the mobile CPU market. It launched in Q2 2023. It is part of AMD's Ryzen 7 lineup, which is based on the Zen 4 microarchitecture. The 7840U is compatible with AMD Socket FP8 motherboards and is fabricated on TSMC's 4 nm manufacturing process. It features the Radeon 780M integrated graphics solution.

Memory and Cache

The Ryzen 7 7840U supports DDR5 memory and features a dual-channel memory controller, allowing it to utilize 2 memory modules simultaneously. In terms of cache, the Ryzen 7 7840U 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 16 MB.

Cores and Clock Speeds

The Ryzen 7 7840U 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 5.1 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 7 7840U includes an integrated graphics solution called 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 7 7840U has the 112th best 3DMark 11 Performance Physics score among the 721 benchmarked CPUs in our database. It achieves 44.54% of the performance of the best benchmarked CPU, the AMD Ryzen 9 7950X3D.

About the AMD Ryzen 5 PRO 7640HS CPU

The AMD Ryzen 5 PRO 7640HS is a 6-core (12-thread) processor built for the mobile CPU market. The PRO 7640HS is compatible with FP7, FP7r2 motherboards and is fabricated on a 4 nm manufacturing process. It features the AMD Radeon 760M integrated graphics solution.

Memory and Cache

In terms of cache, the Ryzen 5 PRO 7640HS has multiple levels of cache. Its L1 cache, which is the smallest and fastest, is 384 KB in size, providing rapid access to crucial instructions. Its L2 cache, at 6 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 5 PRO 7640HS 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 4300.0 MHz, and it can boost up to 5000.0 MHz under heavy workloads. Higher clock speeds result in better performance for the same microarchitecture.

Integrated Graphics

The Ryzen 5 PRO 7640HS includes an integrated graphics solution called AMD Radeon 760M. This graphics processor is directly integrated into the CPU and is not as powerful as a dedicated graphics card.
