What the Xeon E3-1278L v4 is
The Xeon E3-1278L v4 is a soldered Broadwell workstation part on BGA 1364 for compact video boxes. Intel set 4 cores and 8 threads at 2.0 GHz base with turbo to 3.3 GHz. Six megabytes of Smart Cache plus 128 MB of eDRAM feed cores and graphics. Power is 47 W on 14 nm from June 2015.
Low base clocks protect small chassis while turbo covers encode bursts. Iris Pro Graphics P6300 from 800 MHz to 1000 MHz accelerates transcodes without a discrete card. Eight threads handle streams with background tasks. The soldered package means vendors tune cooling once.
DDR3L ECC over two channels feeds the node. ECC suits 24 hour video duty. Buyers pick the 1278L v4 where soldered Iris Pro must transcode in a compact workstation.
Socket and motherboard compatibility
The 1278L v4 solders to BGA 1364 with workstation cooling for 47 W. No socket and no later swap exist. Compact video appliances lock memory with the SoC style package. Check Quick Sync support in the application stack.
Board designs center on display outputs and NICs around the soldered chip. The LGA, PGA and BGA: CPU package types explained guide explains soldered workstation tradeoffs. Confirm 4K output needs before ordering.
Memory, PCIe and cooling
DDR3L ECC over two channels to 32 GB suits video appliances. Paired modules feed Iris Pro encodes. ECC protects long running jobs.
PCIe 3.0 with 16 lanes from the CPU serves capture cards and NVMe. Most builds use integrated Iris Pro for transcodes. A capture card fits where live inputs need it.
Cooling uses compact workstation heatsinks for 47 W. No boxed cooler ships. Sustained encodes need steady chassis airflow.
Upgrade paths
No soldered upgrade exists. Compare the Intel Xeon E3-1258L v4 at 1.8 GHz to 3.2 GHz nearby for lower base, or socketed Intel Xeon E3-1285L v4 parts on C226 boards where swaps are possible. All share the Broadwell-DT family.
