What the Opteron 6338P is
The Opteron 6338P is a 12 core Warsaw server part on Socket G34 for efficient private clouds. It runs 12 Piledriver cores and 12 threads on two dies at 2.3 GHz base with turbo to 2.8 GHz and all core turbo near 2.5 GHz. Twelve megabytes of L2 plus 16 MB of L3 cover guests. Power is 99 W on 32 nm from January 2014.
Twelve cores balance density and clocks for virtualization hosts. Turbo covers bursts while all core loads hold near 2.5 GHz. Four HyperTransport links at 3.2 GHz tie up to four sockets. The 99 W envelope with 27 percent better performance per watt than older 6300 parts suits large deployments.
DDR3-1600 ECC over four channels feeds the two dies. ECC guards cloud guests. Buyers pick the 6338P where 12 threaded cores at 99 W must fit 2S and 4S Supermicro and Sugon nodes.
Socket and motherboard compatibility
The 6338P fits Socket G34 on SR5650, SR5670 and SR5690 boards with Warsaw firmware. The dual die FCLGA-1944 package seats in the 1974 contact socket. Up to four sockets scale one node. Check the vendor stepping list before mixing with older Abu Dhabi parts.
Registered ECC DIMMs populate four channels per socket. The socket SR5600 table covers this Warsaw codename. SP3 EPYC boards never accept Opteron silicon.
Memory, PCIe and cooling
DDR3-1600 ECC over four channels per socket with up to 51.2 GB/s suits cloud guests. Registered modules allow large counts. Even populations across sockets protect NUMA fairness.
No PCIe lanes come from the CPU. HyperTransport links carry socket traffic while PCIe Gen 2 slots hang off the chipset. A 10 GbE fabric suits cluster links.
Cooling uses 2S and 4S server heatsinks for 99 W continuous. No boxed cooler ships. Data center airflow decides sustained turbo.
Upgrade paths
On the same socket, the AMD Opteron 6370P at 16 cores and 2.0 GHz to 2.5 GHz above doubles threads per socket for denser clouds. Both share G34 boards where firmware lists them.
A move to EPYC needs new SP3 boards. The 6338P covers efficient 12 core Warsaw clouds where clocks still matter.
