What the Xeon E3-1558L v5 is
The Xeon E3-1558L v5 brings Skylake to BGA 1440 for video nodes with Iris Pro graphics. It launched in May 2016 with a 1.9 GHz base and up to 3.3 GHz boost at 45 W. Intel targets streaming racks that need four cores with fast graphics and ECC on one chip.
Eight megabytes of Smart Cache carry transcode sessions. The low base clock fits 45 W in dense shelves. Eight threads cover streams plus management agents.
Iris Pro graphics with eDRAM drive encode work without a discrete card. The process is 14 nm. The multiplier is locked. DDR4-2133 in two channels feeds CPU and graphics with up to 64 GB and ECC.
Buyers choose the board at order time with memory size and port tier. The 45 W rating suits 1U video shelves with shared airflow. Quick Sync Video speeds HEVC transcodes where licensed.
Socket and motherboard compatibility
The Xeon E3-1558L v5 is soldered to the board on BGA 1440 and cannot be replaced. Upgrading means replacing the board or the whole node, so choose memory and ports at purchase. Boards pair the chip with SODIMM slots for ECC and video outputs for consoles.
BGA 1440 boards wire PCIe, SATA and USB per node design. LGA workstations cannot take this BGA chip. The LGA, PGA and BGA: CPU package types explained guide explains soldered packages.
Single socket nodes are the deployment. Growth means more BGA 1440 nodes rather than a chip swap. Service follows the board manual for heatsinks and airflow.
Memory, PCIe and cooling
DDR4-2133 in two channels up to 64 GB suits video nodes with many sessions. Matched pairs help Iris Pro graphics during transcodes. Start with 32 GB for streaming use.
PCIe 3.0 with 16 lanes from the CPU serves NVMe and NICs per board layout. Most builds rely on Iris Pro and skip discrete graphics. Chipset lanes add extra storage.
Cooling has no retail mount pattern because the chip is soldered. Vendors design heatsinks for 45 W classes. Keep vents clear where nodes run daily. ECC guards memory.
Upgrade paths
On the same package, the Intel Xeon E3-1578L v5 lifts to 2.0 GHz base at the same 45 W for similar nodes. The Intel Xeon E3-1565L v5 drops to 35 W at 2.5 GHz base for cooler shelves. Both share BGA 1440 boards.
Mobile Intel Xeon E3-1515M v5 gives notebook workstations similar cores at 2.8 GHz base. It needs notebook boards.
Past video nodes move to Coffee Lake-H Xeon E parts. The E3-1558L v5 covers 2016 streaming racks where four efficient cores with Iris Pro must deploy.
