We have seen numerous Intel Z490 motherboards over the months since Intel's platform for Comet Lake was announced back in April. While the Z490 is designed for regular consumers and gamers who intend to use the desktop Intel Core i5/i7/i9 processors, Intel also launched its W480 chipset slightly later which is designed for its workstation orientated Xeon W-1200 series. One such board designed specifically for the Xeon W-1200 processors is the Supermicro X12SAE with support for up to 128 GB of DDR4-2933 of ECC and non-ECC UDIMMs. Also included in the feature set are two PCIe 3.0 x4 M.2 slots, dual Ethernet including a 2.5 Gigabit controller, as well as a dedicated Intel PHY with Intel AMT and vPro support. 

Supermicro X12SAE Overview

For every current W480 model on the market, there are at least 4-5 Z490 variants, which makes Intel's workstation platform slim pickings for choice. One of the reasons behind this is down to necessity, with workstations platforms opting for functionality and core feature sets over bling and fancy designs. What the Supermicro X12SAE lacks in visual appeal, it makes up for in its feature set with much of what we have come to expect from its mid-level professional models. The X12SAE is the only conventional ATX sized model from a trio we looked at when we overviewed the W480 chipset earlier on in the year, and as such, has a lot of features included on its green and basic looking PCB. This unit is designed for mass workstation deployment, rather than aesthetics.

Included in the specifications is a pair of PCIe 3.0 x4 M.2 slots, with drives in both M.2 2280/22110 form factors supported. The X12SAE has a total of four SATA ports with support for RAID 0, 1, 5, and 10 RAID arrays, with dual LAN on the rear panel, one 2.5 GbE controller, and the other via an Intel Gigabit PHY. The glaring difference between the LGA1200 Z490 and W480 chipsets supports ECC memory, albeit unbuffed, with the X12SAE allowing for up to 128 GB of DDR4-2933 across four memory slots. For expansion cards, Supermicro includes three full-length PCIe 3.0 slots operating at x16 and x8/x8/+x4, with one PCIe 3.0 x1 and a single 5 V PCI 5 V 32bit slot.

While there is space on the board for a BMC chip, as shown by the pads above, this model does not have it - users should look to the X12SCA-F for a BMC.

On-board audio is quite standard for a board of this caliber as it uses a decent yet aging HD audio codec, with other rear panel connections including a trio of video outputs consisting of an HDMI, DisplayPort, and DVD-D port. There's also USB aplenty, with support for up to five USB 3.2 G2 ports (four rear panel, one internal), with Type-A and Type-C, as well as three USB 3.2 G1, and two USB 2.0. 


Supermicro X12SAE Block Diagram

Comparing the Supermicro X12SAE paired with an Intel Xeon W-2170 processor with the rest of the LGA1200 models we've tested so far, albeit, with an Intel Core i7-10700K (closely matched), we saw the expected levels of performance. In our system tests, we saw lower power consumption overall, which can be attributed to a lower TDP and lower threshold for increase power requirements without much of the jazzy bells and whistles of desktop models. We also saw slow POST times, which is a trait generally associated with workstation and server models. DPC performance out of the box was average yet acceptable. In our computation tests, our W-1270 performed as well as expected, despite the power allowance differences compared to the Core i7-10700K. It should be noted that the Intel Xeon range isn't designed for gaming and the high-burst performance of the Core series of Comet Lake processors makes them superior for tasks such as gaming when compared to the Xeon range.

It should be noted that we experienced a number of issues with the X12SAE, including memory support, a dodgy thermal sensor, and intermittent networking dropouts. Details are over the next few pages.

The Current Intel Xeon W-1200 (Comet Lake) Product Stack

The Comet Lake based Intel Xeon W-1200 processors include much of the same technologies as its desktop counterparts, with extra single-core performance through Intel's Thermal Velocity Boost and Turbo Boost Max 3.0. This pushes one core much further than others for a prolonged period of time. In total, there are three main models, including the W-1250, W-1270, and W-1290, each with two or three variations, including the P SKU's, with the P meaning performance.

The standard variants include an 80 W TDP, with the P models matching the desktop models at 125 W, with a single T model, the W-1290T with a much lower TDP of 35 W. All of these SKUs include integrated graphics, with support for dual-channel ECC memory, and added security built-in via Intel Hardware Shield.

Putting the WORK into Workstation

Rounding back to the Supermicro X12SAE, it should cost around the $280 mark dependant on the retailer, although Newegg, via a third-party seller, has it listed for $350 at present. Currently, there's not a great deal of competition within the W480 boards on the market, but the GIGABYTE W480 Vision W ($260) is a nice price but resembles a more consumer-focused desktop design and feature set. It certainly doesn't offer the flexibility of remote access and real-time monitoring as the Supermicro. It instead goes for upgraded audio, more SATA. It is a desktop board posing as a workstation board instead of focusing on the professional elements associated with a platform such as W480.

    Wait... a *PCI* slot?! Like from 1992??? Where did they even find the old-new stock of PCI connectors? Crazy to think that a board that worked in a 486 (albeit a limited subset of 486 systems) can work in this board! Reply

    There are a few MB makers that still have PCI / PCI-X / AGP Slots.

    Not sure about VLBus or ISA (8/16) but who needs to install the original soundblaster card or a CGA video card in a new system?

    Old slot types are not for sound or video cards, but for specialized boards for interfacing to expensive machinery where the manufacturer charges and arm and a leg for a modern replacement board (if there is one at all), went out of business, was bought up, etc. Reply

    Some cards that are still used are only available PCI format. Reply

    Great article if one were looking for a low power consumption mobo for W-1270. But that audience must be rather small as there are much better options price/performance wise. Strange. Reply

    Sensors reading out of range and super doctor beeping is typical with supermicro WS boards. It's pretty annoying, I've had several that showen behaviour like this. Reply

    Does the quantity of occupants in nvme openings deduct from the most extreme number of PCIe ways?

    Regularly a NVMe SSD affiliation space is related by a PCIe x4 interface.

    I should use the w-1290t which officially offers Max# of PCIe ways of 16.

    I should use two lsi strike controllers, which everyone uses 8x PCIe ways, leaving 0 for the 2 NVMe SSDs, which I should use.

    Thankful to you for your help
