What the Xeon E5-1660 v4 is
The Xeon E5-1660 v4 brings Broadwell-EP to LGA 2011-v3 for single socket workstations with DDR4. It launched in June 2016 with a 3.2 GHz base and up to 3.8 GHz boost at 140 W. Intel targets render desks that need eight cores with ECC on one chip.
Twenty megabytes of Smart Cache carry scenes and timelines. The steady clocks suit mixed modeling and rendering. Sixteen threads cover batch jobs plus interactive edits.
There is no integrated GPU, so a discrete workstation card is required. The process is 14 nm. The multiplier is locked. DDR4-2400 with ECC in four channels feeds cores with up to 1.5 TB on capable boards.
Buyers add cooling at purchase because no cooler ships in the box. The 140 W rating needs a tower with steady airflow. Turbo Boost Max 3.0 lifts favored cores for single threads.
Socket and motherboard compatibility
The Xeon E5-1660 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 on this SKU. 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 render desks with large scenes. Quad channel bandwidth helps simulation. Start with 64 GB for 3D work.
PCIe 3.0 with 40 lanes from the CPU allows two workstation cards 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 against memory errors.
Upgrade paths
On the same socket, the Intel Xeon E5-1680 v4 lifts to 3.4 GHz base for faster desks with the same 20 MB cache. The Intel Xeon E5-1650 v4 drops to six cores for lower cost towers. Both share LGA 2011-v3 boards.
HEDT Intel Core i7-6900K gives eight cores without ECC for gaming rigs. It needs X99 boards.
Past workstations move to Skylake-W. The E5-1660 v4 covers 2016 render desks where eight cores with ECC must deploy.
