Supermicro X12SDV 16C SPT8F Overview

Supermicro X12SDV-16C-SPT8F 16-core Intel Xeon D-2775TE with 25GbE review

Introducing the Supermicro X12SDV 16C SPT8F

The Supermicro X12SDV-16C-SPT8F was one of the first Intel Ice Lake-D platforms we reviewed. We now have our formal review of this compact motherboard which packs a 16-core processor which is a high-end solution in this space. It also has eight network ports, including 1GbE, 10GbE, and 25GbE. PCIe Gen4 is also new for this generation. This is a premium in-vehicle platform, and in our review we’re going to see why and what features set it apart from previous generations we’ve reviewed.

Supermicro X12SDV-16C-SPT8F Overview

The motherboard is an interesting shape to say the least. It is listed as a mATX motherboard at 7.5″ x 8.5″ (191mm x 216mm). This may seem odd since the standard mATX is 9.6″ x 9.6″ and the mITX is 6.7″ x 6.7″.

This smaller form factor allows Supermicro to use standard mounting holes, but also fit into a shorter depth 1U chassis. Here is an example in a 1U chassis with this motherboard configured.

Here it can be seen that the shorter 7.5″ side is designed to allow a PCIe card on a riser in this system.

Perhaps the biggest feature of this motherboard is the processor. On board we have an Intel Xeon D-2775TE 16 core / 32 thread processor.

The Xeon D-2775TE is part of the Intel Ice Lake D series. Welcome to the Intel Ice Lake D era with the Xeon D-2700 and D-1700 series. We did a big article on that a few months ago. Here is the accompanying video:

This processor is flanked by four DIMM slots. These are DDR4-2933 slots and the chip itself is capable of quad channel memory. It also supports ECC RDIMM and LRDIMM modules which we believe will be used in most applications.

Along the top of the motherboard we get power connectors. What is surprising is the number of 4-pin PWM fan headers. In this photo alone, there are four of them. Supermicro builds this chassis motherboard with active airflow.

What’s important for this generation is that the SATA ports are starting to become a smaller point of interest. We only have two 7-pin SATA ports, one of them gold to power the SATADOM. With M.2, SATADOMs became less popular.

Since the Intel Ice Lake D used is a 100W TDP part, this means the heatsink is larger than what we saw in the Supermicro X11SDV-16C-TP8F and Supermicro X10SDV-7TP8F generations. Although there is no fan on the motherboard, it is not a fanless design. It is designed for use with chassis fans cooling the CPU and other components.

With this generation we get the BMC ASPEED AST2600 which is new in this generation.

Perhaps the biggest feature of this is the new PCIe Gen4 support. This is new for this generation’s Xeon D range. We get a PCIe Gen4 x16 slot along the bottom edge of this motherboard. There is also an M.2 PCIe Gen3 x4 slot.

While this is solid connectivity for a small rig, we also get two 8-way SlimSAS ports for more connectivity. We can see them used for NVMe SSDs as an example.

There is also a 4-lane Oculink connector that provides PCIe Gen3 x4 or 4x SATA III lanes.

The rear IO is perhaps the star of this system. There’s the out-of-band management port, two USB 3 Type-A ports, and a VGA port for standard connectivity. Then there are eight network ports.

On the leftmost side we have SFP28 cages for dual 25GbE connectivity. Next to these we have 10Gbase-T ports powered by Intel X550-at2. This provides high-speed fiber/DAC connectivity as well as 10GbE via standard RJ45.

The other four ports are powered by an Intel i350-am4 processor. It is a high-end 1GbE network card and is the standard for 4x 1GbE connectivity today. Some cards will use 4 Intel i210 1GbE NICs, but the i350 is a more expensive solution with more features.

Overall, this is a truly unique platform due to the amount of power it packs into a mATX-ish motherboard as well as the amount of connectivity built into it. It’s a big generational leap.
