Benchmarks & Specs

Last updated:
The AMD Ryzen 9 3900 represents a remarkable processor from AMD's high-end range. It is built on the efficient Zen 2 architecture, internally codenamed Matisse. Manufactured using the advanced 7nm process, it delivers high energy efficiency. This contributes significantly to its robust overall performance.

A particularly positive feature is the very generous 64 MB L3 cache. This enables fast data access and significantly accelerates various applications. In the current Cinebench 2024 test, the AMD Ryzen 9 3900 achieves 75 points in the single core test. In the multi-core benchmark, it even delivers a remarkable 947 points.

These solid values demonstrate its ability to master even demanding tasks with ease. Integrated support for PCIe 4.0 represents another important advantage. It ensures fast connections for modern graphics cards and NVMe SSDs. With a maximum memory bandwidth of 51 GB/s, data processing is very smooth.

We see that this processor is a compelling option for many users. Its strength in multitasking as well as in complex calculations remains undisputed. This continues to make it relevant.
  • Generous 64 MB L3 cache
  • Strong multi-core performance (947 points in Cinebench 2024)
  • Support for PCIe 4.0
  • Efficient 7nm manufacturing
