AMD EPYC 7773X 64-Core 2.2 GHz 768MB L3 280W Server Processor

SKU CH-CP9Q-VZRDC

A 64-core server processor with 768 MB L3 cache, 2.2 GHz base clock and 3.5 GHz turbo for high-density compute workloads

  • CPU Socket TypeSocket SP3
  • 64 cores and 128 threads handle massive parallel workloads
  • 768 MB L3 cache accelerates data-heavy applications
  • Base clock 2.2 GHz with turbo up to 3.5 GHz
  • DDR4-3200 eight-channel memory delivers high bandwidth
  • 128 lanes of PCIe 4.0 support extensive I/O expansion

Product Identity

The AMD EPYC 7773X is a 64-core server processor with 128 threads and 768 MB of L3 cache. It targets data-centre workloads that scale across many parallel threads such as virtualisation, database analytics and high-performance computing.

Compatibility Check

Verify that your motherboard uses the Socket SP3 interface and supports a 280 W TDP. Confirm the platform provides eight-channel DDR4-3200 memory and 128 lanes of PCIe 4.0 connectivity. Ensure your cooling solution and power delivery are rated for sustained 280 W operation.

Sustained Load Behaviour

The processor maintains a 2.2 GHz base frequency across all 64 cores under continuous load with a 3.5 GHz maximum turbo limit. The large 768 MB L3 cache reduces memory latency during long-running tasks. Thermal design expects steady 280 W dissipation rather than short bursts.

Questions about this item

Does the OEM tray processor come with a cooler or retail packaging?

The 7773X is supplied as an OEM tray unit without a cooler or retail box; a compatible SP3 heatsink must be sourced separately.

How do the 64-core 7773X and the 7763 differ for memory-heavy workloads?

The 7773X provides 768 MB of L3 cache versus the 7763's smaller cache, giving the 7773X a clear advantage when datasets exceed the 7763's on-die capacity.

What sustained throughput can I expect from the 8-channel DDR4-3200 interface?

The eight DDR4-3200 channels deliver up to 204.8 GB/s of memory bandwidth when all channels are populated with supported modules.
