AMD Ryzen 9 Pro 9945 3.4GHz Processor 12 Cores for Socket AM5 Tray

Key features:

  • Socket: AM5
  • Cores: 12
  • Threads: 24
  • Maximum Frequency: 5.4 GHz
  • Cache Memory: 64 MB
See full description

  • CPU Speed

    The speed at which the processor operates in everyday use.

    During the execution of demanding applications (e.g. games), the frequency may automatically increase up to the Maximum Processor Frequency.

  • Cores

    The natural individual processing units that the processor has. The more cores a processor has, the more efficient it is in running multiple applications simultaneously. For simple use, 4 cores are sufficient, while for gaming and video processing, at least 6 are recommended.

  • Socket

    The processor socket type.

    The motherboard we choose should have the same socket in order for the processor to "fit in".

  • Maximum CPU Speed

    The maximum processor frequency is the frequency that the processor can reach when executing demanding applications that use one core. Generally, when running demanding applications (e.g. games), the frequency can automatically increase up to the Maximum Processor Frequency depending on the number of cores in use. (the fewer cores are active, the closer they can operate to the maximum frequency)

  • Cache Memory

    Cache is a very fast memory that acts as an intermediary between the processor and RAM. It stores data that is frequently useful to the processor for faster access.

Zen 5 Architecture for Business

The AMD Ryzen 9 PRO 9945 is based on the innovative Zen 5 architecture, manufactured with TSMC's 4nm FinFET process. It features 12 cores and 24 threads, delivering exceptional processing power that scales according to your business needs. With a base clock of 3.4 GHz and boost capability up to 5.4 GHz, it easily handles everything from complex computations to demanding multitasking.

AMD PRO Comprehensive Protection

Designed for the modern work environment, the processor incorporates AMD PRO technologies. AMD Memory Guard provides full encryption of system memory for protection against physical attacks, while the AMD Secure Processor creates a secure execution environment. These features ensure that sensitive corporate data remains protected at every level of operation.

Advanced Connectivity and Memory

The platform supports the latest cutting-edge technologies, including PCIe 5.0 for ultra-fast communication with storage devices and graphics cards. With support for DDR5-5600 memory and expandability up to 192 GB, the Ryzen 9 PRO 9945 ensures that your system will remain efficient and future-ready, while also supporting ECC memory for maximum data reliability.

Energy Efficiency and Cooling

Despite its high power, the processor maintains an extremely efficient operating profile with a default TDP of 65W. The package includes the AMD Wraith Stealth thermal solution, which offers reliable and silent cooling. The low energy consumption translates to less heat emission and lower operating costs, making it ideal for corporate workstations.

Integrated Graphics and Management

The processor features integrated AMD Radeon™ Graphics with 2 graphics cores at 2200 MHz, allowing for multi-display output without the need for a dedicated graphics card. Additionally, DASH support enables IT administrators to perform remote maintenance and management tasks, simplifying fleet management of computers in large organizations.
