  • Key Specs
    • Processor Socket: Socket AM5 (LGA 1718) (Type of pin configuration that connects a CPU to a computer’s motherboard.)
    • PCI Express Version: PCI Express 5.0
    • CPU Base Clock Frequency: 4.4 gigahertz (Actual central processing unit (CPU) speed may vary by device configuration and design. The average rate at which the processor is able to execute tasks under normal operating conditions as asserted by the manufacturer.)
    • CPU Boost Clock Frequency: 5.5 gigahertz (Actual central processing unit (CPU) speed may vary by device configuration and design. The maximum rate at which the processor is able to execute tasks, typically only used for a short period of time as needed. This rate may temporarily boost the processor's performance, but may result in overheating, shutdown, or damage to equipment if sustained.)
    • Number of CPU Cores: 12-core (A core, or "brain" of a CPU, allows it to receive and execute instructions. Each core can work independently or together to perform parallel operations.)
    • Number of CPU Threads: 24 (Generally, the more threads, the faster and more responsive the operating system.)
    • Unlocked Processor: true
    • Memory Type Supported: DDR5
    • L1 Cache: 960 megabytes (Cache memory, also called CPU memory, is random-access memory (RAM) that a computer microprocessor can access more quickly than it can access regular RAM. This memory is typically integrated directly with the CPU chip or placed on a separate chip that has a separate bus interconnect with the CPU.)
    • L2 Cache: 12 megabytes (Cache memory, also called CPU memory, is random-access memory (RAM) that a computer microprocessor can access more quickly than it can access regular RAM. This memory is typically integrated directly with the CPU chip or placed on a separate chip that has a separate bus interconnect with the CPU.)
    • L3 Cache: 128 megabytes (Cache memory, also called CPU memory, is random-access memory (RAM) that a computer microprocessor can access more quickly than it can access regular RAM. This memory is typically integrated directly with the CPU chip or placed on a separate chip that has a separate bus interconnect with the CPU.)
    • Processor Base Power: 120 watts
    • Integrated Graphics: true (Device has a built-in graphics processing unit.)

    • Unlocked Processor: true
  • Memory
    • Maximum Memory Supported: 192 gigabytes
    • Memory Type Supported: DDR5
    • Cache Level: L1, L2, L3 (The cache stores data that the CPU needs to access quickly in order to complete tasks. Each level is ranked according to priority of access; Level 1 (L1) cache stores data that the CPU needs to access first. L1 cache is also the fastest but holds the least amount of data, with each following level decreasing in speed but increasing in capacity.)
