About the AMD Ryzen 9 3900 CPU

The AMD Ryzen 9 3900 is a 12-core (24-thread) processor built for the desktop CPU market. It launched in Q3 2019 with a suggested retail price of $499. It is part of AMD's Ryzen 9 lineup, which is based on the Zen 2 microarchitecture. The 3900 is compatible with AMD Socket AM4 motherboards and is fabricated on TSMC's 7 nm manufacturing process.

Memory and Cache

The Ryzen 9 3900 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 3900 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 64 MB.

Cores and Clock Speeds

The Ryzen 9 3900 features 12 total cores which can process 24 threads simultaneously. The multi-threading capability allows the CPU to execute multiple computational tasks in parallel. The base clock speed of the CPU is 3.1 GHz, and it can boost up to 4.3 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 3900 does not include an integrated graphics solution. A dedicated graphics card will be required if you require a monitor with your computer.
