What the Xeon E-2136 is
The Xeon E-2136 is a six core, twelve thread workstation processor with a 3.3 GHz base and up to 4.5 GHz turbo. It carries 12 MB of Smart Cache and an 80 W TDP on the 14 nm process. Intel announced it on July 12, 2018 as the top six core of the E-2100 launch for single socket workstations.
Hyper-Threading doubles the threads over the quad core E parts, which helps rendering, compilation and CAD beside office loads. The 4.5 GHz turbo tops the launch stack for bursty single threaded work. The multiplier is locked at 33 times the 100 MHz base clock.
It has no integrated graphics: the ARK page carries no graphics section, WikiChip confirms no engine, and ServeTheHome notes it as one of the few E-2100 parts without an iGPU. A separate workstation card is mandatory. Launch pricing is left out here because ARK and launch coverage disagree between $284 and $319.
Socket and motherboard compatibility
The E-2136 fits LGA 1151 revision 2 on workstation boards with the C242 and C246 chipsets. Consumer 300 series boards are not the target, since ECC wiring lives on the workstation boards. Check the board maker CPU list for the exact E-2136 before ordering.
It does not fit 100 or 200 series boards, which are revision 1 for 6th and 7th Gen chips. A workstation card is mandatory, so pick a board with the PCIe x16 slot wired at full speed. The Intel Xeon E-2278G is a later eight core option on newer boards where threads grow further.
Boards sold after mid 2018 accept it with the shipping BIOS where the maker lists the part. Mid tower workstations with a Quadro card and ECC memory suit mixed CAD and creation.
Memory, PCIe and cooling
Memory support is DDR4-2666 in two channels up to 128 GB, with ECC correcting single bit errors. Intel notes the 128 GB level needed a 2019 BIOS update on supporting boards. Two matched ECC UDIMMs give dual channel speed with error cover for long renders.
PCI Express arrives as version 3.0 with 16 lanes from the CPU for graphics and storage. A workstation card and two NVMe drives fit the lane budget of a mid tower. Cooling uses the shared 75 mm LGA 1151 pattern at 80 W, with boxed parts including a thermal solution.
Upgrade paths
On the same socket there is little above six cores in the E-2100 line for this board generation, so growth means memory, storage or graphics rather than threads. Owners coming from quad core E parts double their threads in one drop-in while keeping board and ECC DDR4.
Moving past LGA 1151 means a new board on a current workstation platform. Owners usually add ECC memory or a faster workstation card before replacing the processor.
Frequently asked questions
What socket does the Xeon E-2136 use?
It uses LGA 1151 revision 2 on C242 and C246 workstation boards. Consumer 300 series boards are not the target.
How many cores does the E-2136 have?
Six cores with Hyper-Threading give twelve threads at 3.3 GHz base with up to 4.5 GHz turbo, with 12 MB of cache at 80 W.
Does the E-2136 have integrated graphics?
None. The ARK page carries no graphics section and reviewers confirm it, so a separate workstation card is required.
What memory does the E-2136 support?
DDR4-2666 in two channels up to 128 GB with ECC for error cover on long jobs. The 128 GB level needed a 2019 BIOS update.
What replaces the E-2136 with more cores?
The Intel Xeon E-2278G is a later eight core option on newer boards. The E-2136 keeps its place where six fast cores cover the work.
