What the Xeon E5-1620 v4 is
The Xeon E5-1620 v4 brings Broadwell-EP to LGA 2011-v3 for entry workstations with DDR4. It launched on June 20, 2016 with a 3.5 GHz base and up to 3.8 GHz boost at 140 W. Intel targets CAD desks that need four cores with ECC at a lower price.
Ten megabytes of Smart Cache carry models and drawings. The high base clock keeps drafting responsive. Eight threads cover design apps plus office tasks.
There is no integrated GPU, so a discrete workstation card is required. The process is 14 nm on a 246 mm2 die. The multiplier is locked. DDR4-2400 with ECC in four channels feeds cores with up to 1.5 TB.
Buyers add cooling at purchase because no cooler ships in the box. The 140 W rating needs a tower with steady airflow. A 69 C case limit guides thermal design for warm rooms.
Socket and motherboard compatibility
The Xeon E5-1620 v4 fits LGA 2011-v3 on C612 workstation boards and X99 boards with DDR4 slots. Makers list Broadwell-EP with 2016 BIOS builds. Early stock may need an update.
Single socket builds are the case with no QPI link. Dual socket racks need E5-2600 v4 parts. The Socket vs chipset: what decides whether a CPU works guide covers matching.
Tower workstations with one socket are the deployment. Another LGA 2011-v3 chip can follow where listed. Power needs solid rails for 140 W plus graphics.
Memory, PCIe and cooling
DDR4-2400 with ECC in four channels suits entry workstations with SSD boot drives. Quad channel bandwidth helps large drawings. Start with 32 GB for CAD work.
PCIe 3.0 with 40 lanes from the CPU allows workstation graphics plus NVMe. Chipset lanes cover extra SATA and USB.
Cooling follows the 80 by 80 mm pattern in the CPU cooler compatibility by socket guide. A 140 W tower holds boost. No cooler ships in the box. ECC guards memory.
Upgrade paths
On the same socket, the Intel Xeon E5-1630 v4 lifts to 3.7 GHz base for faster desks with the same cache. The Intel Xeon E5-1650 v4 moves to six cores for heavier multitasking. Both share LGA 2011-v3 boards.
HEDT Intel Core i7-6800K gives six cores without ECC for gaming rigs. It needs X99 boards.
Past workstations move to Skylake-W. The E5-1620 v4 covers 2016 CAD desks where four cores with ECC must deploy at entry cost.
