What the Xeon E5-2698B v3 is
The Xeon E5-2698B v3 is a 16 core Haswell-EP OEM part on LGA 2011-v3 for cloud dual socket nodes. It runs 16 cores and 32 threads at 2.0 GHz base with turbo to 3.4 GHz. Forty megabytes of Smart Cache feed dense guests. Power is 135 W on 22 nm from the first quarter of 2015. The B suffix marks a cloud tuned bin with lower base and high turbo.
Sixteen cores maximize threads per socket for consolidation. Low base clocks protect power while turbo covers bursts to 3.4 GHz. Two QPI links tie dual sockets. OEM distribution means support follows vendor nodes rather than retail boards.
No integrated graphics exist. DDR4 with ECC over four channels feeds the node. Buyers meet it in refurbished cloud servers where 16 cores at 135 W fit density plans.
Socket and motherboard compatibility
The 2698B v3 fits LGA 2011-v3 on C612 Grantley boards with OEM firmware. The LGA-2011-3 and Socket R3 names in third party listings refer to this same v3 socket. Check the vendor node list for the B bin microcode.
DDR4 RDIMMs with ECC populate four channels per socket. The Socket vs chipset: what decides whether a CPU works guide covers ideas, vendor docs decide layouts. LGA 2011 without v3 never boots.
Memory, PCIe and cooling
DDR4 ECC over four channels to 768 GB per socket suits cloud hosts. Registered modules allow full counts. Speeds reach 2133 MHz. Even populations protect per core bandwidth.
PCIe 3.0 with 40 lanes per socket serves NVMe and networking. Density favors fabric throughput. NUMA aware scheduling trims tail latency.
Cooling uses 135 W server heatsinks with strong airflow. Sixteen cores run hot under all core loads. Refurbished nodes need paste and fan service to hold turbo.
Upgrade paths
On the same socket the Intel Xeon E5-2678 v3 at 12 cores with higher clocks suits latency work, while the Intel Xeon E5-4667 v3 at 16 cores covers 4S density. All share LGA 2011-v3 where firmware lists them.
A v4 move needs new firmware. The 2698B v3 covers OEM 16 core density where cloud supply decides.
