Despite having officially launched back in July, Intel’s Xeon E desktop platform has yet to see the light of day in systems casually available to users or small businesses. This should change today, with the official embargo lift for reviews on the parts, as well as the announcement today that SGX-enabled versions are coming for Server use. The Xeon E platform is the replacement for what used to be called the E3-1200 family, using Intel’s new nomenclature, and these parts are based on Intel’s Coffee Lake (not Coffee Lake Refresh) microarchitecture. We managed to get a few processors in to test, and today we’ll start by examining most of the six-core family.
Xeon E3 becomes Xeon E
Ever since the launch of Intel’s Xeon Scalable platform naming scheme, most of the Xeon product stack has gone through a naming scheme transformation. The E5 and E7 families were rolled into the Xeon Scalable line with names like Platinum, Gold, Silver, and Bronze, while the workstation focused Xeon E5-1600 parts are now called Xeon W. With that in mind, Intel also changed the Xeon E3-1200 family, into Xeon E, with E being for Entry.
|Intel Xeon Naming Strategy|
|Servers||E7-8000||'v1'||v2||v3||v4||Xeon SP Platinum
Xeon SP Gold
Xeon SP Silver
Xeon SP Bronze
The target market for these processors is still the same: ECC enabled versions of consumer Core family parts, with slightly different base frequencies, turbos, pricing, and TDP values. Users who follow the Xeon E product line will have noticed that some of the processors in this family have the integrated graphics disabled, but also the pricing structure is often a notch above the consumer parts.
Despite the fact that the consumer product line recently launched the 9th Gen Core, known as ‘Coffee Lake Refresh’, the Xeon E-2100 family being reviewed today belongs to the non-refresh version of Coffee Lake. This is mostly down to the timing – the market that Xeon E is after often requires additional testing and qualification. It still doesn’t explain why the launch was in July but the performance embargo lift is today. But here we are.
Xeon E-2100 Family
As we reported back in July, Intel is coming out with a range of quad-core and six-core parts for Xeon E. Those labeled with ‘G’ at the end of the name will have integrated graphics.
Sitting at the top is the Xeon E-2186G, a six core processor with a TDP of 95W, a base frequency of 3.8 GHz, and a turbo frequency of 4.7 GHz. In the past, the top processor was often called the ‘E3-1285’, so the naming scheme follows. The top Xeon E/E3 bin was always an odd processor in general: for most of the previous generations, it offered a slight bump (often +100 MHz) over the second best bin, but the price increased by 40-60% to around $620. In this case we see that the E-2186G is indeed a 100 MHz increase in base frequency over the E-2176G, from 3.7 GHz to 3.8 GHz, although the price increase is a slightly more modest 24% increase this time. Well, there’s always more room at the top, should Intel ever decide to release 8-core variants.
The E-2186G is the only part listed with a TDP of 95W, while the rest are 80W for the six-core parts and 71W for the four-core parts. Every chip has hyperthreading, except for those with a third digit of ‘2’, such as the E-2126G, E-2124G, and E-2124. The processors with integrated graphics, the ‘G’ processors, are using the ‘Pro’ equivalent of the UHD 630 graphics we see on consumer Coffee Lake. In this instance, the iGPU is called UHD P630. Frequencies of the iGPUs, as well as DRAM frequencies, match the consumer parts as well.
Aside from the official parts listed, Intel also has two off-roadmap SKUs that we can find: the Xeon E-2106 and Xeon E-2104. These are not normally searchable on Intel’s database if we look at the ‘overall Xeon E family’ specifications, but users can find them by putting in the exact name into the search. These parts will be OEM only, and Intel often makes them with specific customers in mind.
If we do some direct comparisons with the consumer variants of the processors, we get the following:
|Xeon E-2176G||Core i7-8700K||Xeon E-2174G||Core i5-8600K|
|6 / 12||6 / 12||Cores||4 / 8||6 / 6|
|3700 MHz||3700 MHz||Base Freq||3800 MHz||3600 MHz|
|4700 MHz||4700 MHz||Turbo Freq||4700 MHz||4300 MHz|
|80 W||95 W||TDP||71 W||95W|
|UHD P630||UHD 630||IGP||UHD P630||UHD 630|
In both cases the TDP listed for the consumer parts is higher - for the six cores with hyperthreading the rest of the spec is the same, but for the quad-core vs six core it comes with a difference in frequency as well. The consumer parts have overclocking, while the Xeon parts can use ECC memory. Pricing is also higher on the Xeon E parts, as they also support vPro.
Using a Xeon E-2100 Processor: Choosing a Motherboard
When Intel launched the E3-1200 v5 family two generations back, the company made a conscious decision to split the interoperability between the consumer Core processors and the commercial Xeon E3 processors. This means that there are specific chipsets and motherboards for each, and users could no longer mix-and-match, at least as far as putting a Xeon E3 into a consumer 200-series motherboard. Instead, users had to look to the C-series chipset enabled motherboards to get them to work. Intel is carrying that policy over for the Xeon E family as well, which requires new motherboards compared to the E3-1200 v5/v6 generations.
For example, in our review today we are using one of Supermicro’s Xeon E motherboards, the X11SCA-W. This motherboard uses the C246 chipset, which is the commercial/enterprise version of the Z390 chipset without the overclocking and with ECC memory support.
Because of this C246 requirement, there will be very few motherboards on the shelves for users that want to build their own Xeon E machine, as most of the primary motherboard manufacturers make one or two retail models and that’s about it. We’ve seen GIGABYTE and Supermicro show a single Xeon E motherboard at a trade show each, but for the others it is anyone’s guess.
Gavin Bonshor, our motherboard reviewer, will have a full review of the X11SCA-W ready in the next couple of weeks.
Intel’s Announcement Today, and This Review
Today Intel is officially announcing Xeon E for server customers. Up until this point it would seem that Intel was focusing more on professional desktop environments, but now the Xeon E platform is going to the datacenter. Intel is keen to point out that these parts for the server market support security features such as SGX.
For this review, we managed to obtain several of the processors in advance, several six-core and four-core units. Due to time constrains, we have only been able to test the six-core processors in our CPU benchmark suite so far, so we will follow up with another piece in a few weeks with the four-core variants. If we test them all, I’ll write a fresh article with the full analysis.
In the interest of disclosure, Intel did not sample any of the processors tested today. Intel contacted us about a week ago on sampling, and is set to sample us one of the parts we do not yet have, though it was not available in time for the embargo today. I’m on the lookout to borrow the others from our partners. Please get in touch if that could be you!
In this review, we are taking the E-2186G, the E-2176G, the E-2146G and the E-2136 through our workflow to gauge performance. The focus will be on the CPU metrics in the first few pages, however we are also including the gaming performance with a GTX 1080 as well as the integrated graphics performance. The main comparison points will be the equivalent consumer processors, and previous generation Xeon E3 processors that we could acquire.

bolkhov - Friday, November 9, 2018 - linkYes it does.
72 for ECC vs. 64 for non-ECC.
notb - Wednesday, November 7, 2018 - linkGo ask your IT department if Ryzen's ECC "support" passes their security policy. :-)
twtech - Sunday, November 18, 2018 - linkMost IT departments don't build their own systems. They'll standardize with something like Dell or HP, and maybe do things like RAM/HDD upgrades, etc.
The cost of the CPU in a system is usually a relatively small cost compared to the overall total. Support costs can dwarf initial purchase costs. The more that a company can standardize their hardware, the easier it is to maintain it.
For example, IT may want to test patches before letting them be applied across the organization. If, in an ideal scenario, every system was exactly the same, then potentially only one test would be needed to make sure it works properly.
Of course that often won't be possible, but the closer they can remain to that ideal, the better.
HStewart - Monday, November 5, 2018 - linkTo me it looks like AVX 512 gets a whopping 44% ( ~ 5200 / 3600 ) increase on similar equip similar CPU. It would be nice to see same cpu with and without AVX 512 enabled test.
osrk - Monday, November 5, 2018 - linkFYI provantage told me they were getting in their shipment Nov 12. I have one on pre order.
Dr_b_ - Monday, November 5, 2018 - linkHave my 2186G on pre-order with them as well, for over a month now. Already have the 64GB ECC UDIMMs and Asus C-246 Pro board just waiting. IMHO, the biggest let down with the Asus board is that it doesn't have USB 3.1 2.0 header on the motherboard. Have inquiry with Asus about support for 9900K CFL-R CPU's haven't heard back yet.
mooninite - Tuesday, November 13, 2018 - linkDid you get yours shipped out yet? Websites are still showing either "out of stock" or "special order" for these Xeons.
osrk - Friday, November 16, 2018 - linkNo. They've had them in and out of stock. If you pre-ordered and the item comes in stock for even a penny more your item will not be shipped. They will only fulfill your order when the item comes into stock for the amount you paid. This has left a very bad taste in my mouth when ordering with Provantage and I'm likely not going to order from them again.
For example the E-2176G was in stock with them for $1 more than I paid. Did they ship it or notify me that I could pay the extra $1 and have it ship? Nope. I'm writing up my experiences with them on the ratings site.
Dragonstongue - Monday, November 5, 2018 - linkwonder how much of these things tested are "biased" towards making Intel look as "rosy" as possible to steer away any shortcomings.. I would imagine they have very specific test methodology to ensure "weakness" are not shown.. Probably will never happen, but it would be real nice if "everyone" raced on the same track sort of speak so the best "car" wins, not because other "cars" are hobbled by illegitimate tactics.
AnnoyedGrunt - Tuesday, November 6, 2018 - linkYes, I suspect that Anandtech opened the "hood" on the AMD "cars" and drained their "blinker fluid" and damaged their "muffler bearings" so they couldn't "race" as well.
I'd go on, but I ran out of quotation marks.
