Benchmarks & Specs

Last updated:
The AMD Ryzen 9 PRO 9945 presents itself as an extremely powerful CPU for demanding tasks. It relies on the brand new Granite Ridge architecture, which we also know as Zen 5. This modern foundation not only promises a significant increase in computing power but also improved efficiency.

Manufactured using the advanced 4-nm process, this processor achieves a high transistor density. This leads to remarkable energy efficiency, even under intensive use. Professional users find a reliable and fast solution in this chip. The generously sized 64 MB L3-Cache is another plus point. It enables the AMD Ryzen 9 PRO 9945 to process very large and complex data volumes without delay.

Applications that depend on fast data access benefit significantly here. The integration of PCIe 5.0 is also an important aspect. It offers future-proof connectivity for the fastest storage media and expansion cards. This ensures workstations remain up-to-date for years to come. The package is complemented by integrated AMD Radeon Graphics (Raphael).

This enables image output and saves a separate graphics card in many office environments. We were amazed at how well this integrated solution works for everyday tasks. The memory bandwidth of 90 GB/s also ensures quick work with large files. The AMD Ryzen 9 PRO 9945 is therefore an excellent choice.

It is perfectly suited for anyone who needs high and consistent performance.
  • Modern Zen 5 Architecture (Granite Ridge)
  • Efficient 4-nm manufacturing
  • Future-proof PCIe 5.0 support
  • Generous 64 MB L3-Cache
