Description

The EPYC 7773X adds AMD 3D V-Cache technology, expanding L3 to an exceptional 768 MB per socket to accelerate cache-sensitive workloads like EDA, FEA/CFD, databases, and analytics. Built on Zen 3 (Milan-X), it combines 64 cores with PCIe 4.0 and DDR4-3200 for balanced compute and I/O performance in 1P or 2P servers.

Features

- Massive 768 MB L3 cache with 3D V-Cache for cache-bound workloads
- 64 cores of Zen 3 compute for high parallelism
- 128 PCIe 4.0 lanes for extreme I/O bandwidth
- Enterprise-grade security features (SEV/SEV-ES/SME)
- Drop-in potential on many Milan platforms with firmware updates

FAQs

Q: What is the advantage of 3D V-Cache on the 7773X?
A: The 768 MB L3 cache significantly improves performance on cache-sensitive workloads such as EDA, FEA/CFD, and certain databases.

Q: Is the 7773X compatible with my existing Milan platform?
A: Most Milan platforms can support Milan-X with a BIOS/BMC update; check your server’s CPU support list.

Q: Can I use this in a dual-socket server?
A: Yes. It supports both single- and dual-socket configurations.

Q: Does it require special memory?
A: No. It uses standard ECC DDR4 up to 3200 MT/s across 8 channels per socket.

Q: Is a cooler included?
A: No. Cooling is platform-specific and typically sold separately.
