Kaby Lake E3-1200 v6 Xeon Specifications Leaked
by Ian Cutress on January 24, 2017 5:00 AM EST
Some sleuthing by CPU-World has uncovered the list of to-be-released Kaby Lake single-socket quad-core Xeons. As it to be expected, these are incremental updates from Skylake-based Xeons using the newer 14nm Plus node from Intel. In our consumer Kaby Lake reviews, our results showed that the new design offers a better voltage/frequency profile than previous generations, affording more frequency at the same voltage. Another big change from the previous generation is the TDP: what used to be 80W is now listed as 73W if it has integrated graphics, or 72W if it does not.
The list from CPU-World, who in turn discovered a QVL (qualified vendor list, or ‘CPUs which we confirm work in this board’) posting from a motherboard manufacturer whom accidentally included the new Xeons. The posted list features eight Xeon processors altogether. The two at the bottom of the stack are quad core parts without hyperthreading, and the others do have hyperthreading. The main differences between the processors will be frequencies and the presence of integrated graphics.
| Intel E3-1200 v6 CPUs (Kaby Lake) | ||||||
| C/T | Base Freq | L3 Cache | IGP | IGP Freq | TDP | |
| E3-1280 v6 | 4/8 | 3.9 GHz | 8 MB | - | - | 72 W |
| E3-1275 v6 | 4/8 | 3.8 GHz | 8 MB | P630 | 1150 MHz | 73 W |
| E3-1270 v6 | 4/8 | 3.8 GHz | 8 MB | - | - | 72 W |
| E3-1245 v6 | 4/8 | 3.7 GHz | 8 MB | P630 | 1150 MHz | 73 W |
| E3-1240 v6 | 4/8 | 3.7 GHz | 8 MB | - | - | 72 W |
| E3-1230 v6 | 4/8 | 3.5 GHz | 8 MB | - | - | 72 W |
| E3-1225 v6 | 4/4 | 3.3 GHz | 8 MB | P630 | 1150 MHz | 73 W |
| E3-1220 v6 | 4/4 | 3.0 GHz | 8 MB | - | - | 72 W |
Most of these numbers come direct from the motherboard validation lists, with some such as core count being derived from L2 cache listings. All the parts listed have a full 8MB of L3 cache, indicating they run closer to the Core i7 design rather than a Core i5 (even those that have hyperthreading disabled).
On the integrated graphics models, i.e. those ending in '5', are all running Intel HD P630 graphics and run up to 1150 MHz. This is the ‘professional’ version of the HD630 we see on the consumer parts, using Intel’s latest Gen9 graphics architecture and supporting H.265 encode/decode. Our Kaby Lake review piece goes into more detail.
Not listed are the turbo frequencies of the CPUs, as these are currently unknown. Neither is the pricing, however given previous launches we would expect the tray price (OEM batches of a thousand CPUs) to have parity compared to previous generations.
| Intel E3-1200 v6 and v5 CPUs | ||||
| IGP | v6 | Model | v5 | IGP |
| - | 3.9, 72W | E3-1280 | 3.7/4.0, 80W | - |
| + | 3.8, 73W | E3-1275 | 3.6/4.0, 80W | + |
| - | 3.8, 72W | E3-1270 | 3.6/4.0, 80W | - |
| - | - | E3-1260L | 2.9/3.9, 45W | - |
| + | 3.7, 73W | E3-1245 | 3.5/3.9, 80W | + |
| - | 3.7, 72W | E3-1240 | 3.5/3.9, 80W | - |
| - | - | E3-1240L | 2.1/3.2, 25W | - |
| - | - | E3-1235L | 2.0/3.0, 25W | + |
| - | 3.5, 72W | E3-1230 | 3.4/3.8, 80W | - |
| + | 3.3, 73W | E3-1225 | 3.3/3.7, 80W | + |
| - | 3.0, 72W | E3-1220 | 3.0/3.5, 80W | - |
For the most part, the new processors are ~200 MHz faster than the v5 parts while still being rated at the lower TDP. Memory support is expected to be the same as the consumer parts (DDR4-2400), and it is not yet confirmed if the v6 processors will support Transactional Synchronization Extensions (TSX) given issues in previous revisions, so we will wait on future Intel announcements on this front.
It is still worth noting that for LGA1151 based Xeons, Intel adjusted the requirements such that Xeon processors require a server grade chipset on the motherboard. For Skylake E3 v5 parts, this was either a C232 or C236 chipset – we reviewed a few motherboards with these on (ASRock E3V5 Gaming, GIGABYTE Z170X-Extreme ECC). With a BIOS update, these C232/C236 motherboards should support the new v6 processors. However, we currently do not know if there will be a second generation of chipsets for these CPUs in line with the consumer updates. On the consumer side the new chipset has additional PCIe lanes and Optane Memory support, so we stand in wait for a new desktop chipset to support these. There is a new mobile chipset, CM238, for mobile E3 v6 Xeons, but no equivalent in the desktop space yet.
We currently have all the Skylake E3 v5 Xeons in for testing on our new benchmark suite soon, and we’ll make similar moves to acquire the Kaby Lake E3 v6 models when they are released. Currently there is no word on release date or pricing, however we typically see the E3 Xeons release very shortly after the consumer processor release.

I work for one of the largest Microsoft customers in the world by user base. My IT just told me that they have cancelled all plans for migration to 10 on any system.Unless Microsoft releases a highly scrubbed, business specific version of 10, its getting skipped just like Vista and 8.

@Cygni - Since MS claims that Windows 10 will be the last version of Windows - read "they will provide rolling upgrades without actually changing the OS name" - "skipping" Windows 10 might be a real feat. Regardless, it's not like nobody tried it before, just that most of those who did are now trying to wipe that specific job experience from their CVs. Usually the result of their handy work and sound decision making made the news.Most of the time the major roadblock is that companies develop some internal application(s) or framework that relies on a specific OS like Win7 and can't be easily made to work on a newer one. So while the developers crack a bottle of champagne saying their job is done until the next-next version of Windows (you know... Windows 11 or smth) the admins have to scramble and find a solution. And that is usually to "cancel all plans for migration".
2 years from now they still won't have a "highly scrubbed, business specific version of 10" (whatever that is, I expect something was lost in translation between the IT guys, the messenger and you - it can't mean they expect MS to develop and maintain a completely separate edition) but they will scramble to migrate under pressure from management to do it by the end of extended support.

Oh, come on, "just told" and "cancelled all plans" is a dead giveaway already.niva - Tuesday, January 24, 2017 - link
What are you talking about Intel planning? Drivers and architecture by Intel are completely open. I have a new Kaby Lake laptop and as far as the CPU on it is concerned everything runs fine in linux. Drivers for Windows are a Microsoft deal, unless there's something I'm not understanding here.azrael- - Wednesday, January 25, 2017 - link
So, in your opinion Microsoft writes the drivers for nVidia's, AMD's and Intel's graphics cards. And Intel's storage products (RST). And Intel's networking products. And... and... and... well, you get the drift.While Microsoft can and does provide basic driver support shipping with Windows drivers supporting advanced features are developed and released by the manufacturers themselves. Microsoft only performs driver validation (WHQL), if asked (and paid) to.
While the CPUs themselves will probably still work (they're x86/x64) there's a whole eco system that follows with it, e.g. the chipset and onboard devices (storage, network etc.) on the motherboard and of course the integrated GPU of the CPU.
Intel (and AMD apparently) have stated that their latest CPUs will only support Windows 10 with drivers. Why? Because Microsoft has forced them to. How they achieved that is a bit beyond me, since Microsoft needs Intel and AMD more than they need Microsoft.
Google "Kaby Lake Windows 7" for more.

"Forced"? They were happy to support just one driver set, you can be sure of that.Zan Lynx - Sunday, January 29, 2017 - link
The Kaby Lake turbo features require operating system scheduler support. That's why Intel can't fix it, even if they wanted to, because they can't write a driver that replaces the Windows task scheduler.Meteor2 - Tuesday, January 24, 2017 - link
Businesses are changing to 10. Slowly, but it's happening.Some places wait until hardware refreshes for OS changes and with IT kit often being up to five years old, it takes time.

Oooh 8 watts. Take my money.Anato - Tuesday, January 24, 2017 - link
There is +200MHz too, definitely worth upgrade :P
