What the Xeon E3-1284L v4 is
The Xeon E3-1284L v4 balances clocks with Iris Pro graphics on LGA 1150 for 47 W workstations. Intel set 4 cores and 8 threads at 2.9 GHz base with turbo to 3.8 GHz. Six megabytes of Smart Cache plus 128 MB of eDRAM feed the cores. Power is 47 W on 14 nm from June 2015.
High base clocks for a 47 W part suit mixed workstation loads with media duty. Turbo to 3.8 GHz matches the fastest E3 v4 bursts. Iris Pro Graphics P6300 up to 1150 MHz transcodes without discrete heat. Eight threads cover builds beside encodes.
DDR3 ECC over two channels to 32 GB feeds the node. ECC protects workstation data. Buyers pick the 1284L v4 where 47 W must still carry near flagship clocks with Iris Pro.
Socket and motherboard compatibility
The 1284L v4 fits LGA 1150 on C226 workstation boards. The socket C226 table covers this codename. The 47 W L suffix suits compact tower and rack boards. Consumer firmware lacks workstation validation.
ECC UDIMMs to 32 GB are standard. LGA 1151 never boots Broadwell. Board graphics outputs decide Iris Pro connectivity.
Memory, PCIe and cooling
DDR3-1866 ECC over two channels to 32 GB suits balanced workstations. Dual channel feeds Iris Pro encodes. Full memory helps large projects.
PCIe 3.0 with 16 lanes from the CPU serves NICs and NVMe scratch. Media nodes use lanes for flash arrays. A 10 GbE NIC suits shared storage.
Cooling uses 47 W tower or 1U sinks with steady airflow. High sustained clocks need cool inlets. No boxed cooler ships.
Upgrade paths
On the same socket the Intel Xeon E3-1285L v4 at 3.4 GHz base above adds clocks with 65 W tuning, while the Intel Xeon E3-1265L v4 at 2.3 GHz base below saves power. All share C226 boards where listed.
A move to E3 v5 needs C236. The 1284L v4 holds balanced 47 W Iris Pro in Broadwell workstations.
