Intel Announces Xeon Scalable Processor Family (hothardware.com)

MojoKid writes: Intel unveiled information regarding a new Xeon processor family today, some of which will be based on the company's Skylake-SP architecture. Intel will have four levels of Xeon processors that scale with respect to feature support and core counts. Intel is calling it the Xeon Scalable Family with Bronze, Silver, Gold and Platinum processors. Today, Xeon model names follow a fairly easy-to-understand format. Take for example the Xeon E5-4640 v4. "E5" in this case means that it is in the middle of Intel's current stack in terms of features and capabilities, where the "4" signifies use in a 4-socket system. Finally, the "v4" represents the architecture. With this change, a model like the one above would become Intel Xeon Gold 4640, as an example. Regardless, the chips will include support for AVX-512 instructions, QuickAssist and Volume Management Device (VMD) technologies that will take advantage of NVMe solid-state drives. The platform will also support complementary processing engines and IO technologies like Intel FPGAs, Xeon Phi accelerators and Silicon Photonics connectivity. Intel notes the processors will be arriving to market this summer.

Why 4-digits

[Luthair]

When the last one is always zero.

Re:Why 4-digits

[OrangeTide]

The last digit is the number of back doors MOD 10.

When the last one is always zero.

Because it was designed in America, where three houses on a cul-de-sac will each have a four digit house number. Americans love superfluous digits.

But I shouldn't ridicule Americans too much, since some other countries have numbering schemes that are even sillier. For instance, in Japan, houses on a block are not numbered in sequence, but in the order in which they were built.

Re:Why 4-digits

[crow]

It depends on where you are. In my town, house numbers start in the single digits. This causes a problem if the street is extended in the wrong direction, as happens from time to time. In the town I grew up on, the streets are numbered as if they extended to the center of town, so houses between 1st and 2nd streets are in the 100s, but streets ten miles away have five-digit addresses (it's a large city). That works well, as you can often tell about where something is by the street number even if you've never heard of the street.

First question

[geekymachoman]

Does it have a brand new NSA backdoor in it ?

Re: Scalable hardware???

[threephaseboy]

Yeah, Intel would never do something like charge people to unlock features present in the CPU they bought

Not an "unveiling" -- an accidental leak

[djembe2k]

Intel didn't "unveil" anything -- they accidentally posted a "product change notification" that listed model numbers for upcoming Skylake Xeon processors, then quickly took it down. What we've learned is that the model numbering system will change, maybe in a way that keeps a similar organization but renames things, and maybe in a way that means substantive changes. We can't tell. In other words, this is semantics. If there's more to be gleaned from the leak, I haven't heard it here.

Re:Not an "unveiling" -- an accidental leak

[Anonymous Coward]

This summer they are planning on releasing Coffee Lake, which will be 8xxx in desktops (ex: i7-8700K, or whatever). 8 is getting close to 0, so they are probably going to have to rebrand that. The Xeons had a bit more life in them- a coffee lake Xeon would only be "v6", and it isn't out yet. Their enthusiast chips, should they keep that artificial market, would be out at a similar time to the Xeons (some time in the future- the Skylake enthusiasts aren't even out yet), would be something like "i7-9950X" or whatever.

Basically, they'll probably be rebranding all their shit soon. I don't think we even know how to read the new Xeons- is a Gold 2667 comparable to an E5-2667 v4? Basically, how do you tell the difference between a Gold 2667 Skylake, and a Gold 2667 Coffee Lake, without the version number?

Why?

Re: Scalable hardware???

[by (1706743)]

This is similarly done with the Raspberry Pi family.

Of course, I find this significantly more palatable, as a) the whole computer only cost $35, and b) I think it's due to some licensing agreement with a separate entity (Broadcom).

So what you're saying is...

The naming scheme wasn't convoluted enough so far?

Obligatory:Intel CPU Backdoor Report (May 1 2017)

[Anonymous Coward]

The goal of this report is to make the existence of Intel CPU backdoors a common knowledge and provide information on backdoor removal.

What we know about Intel CPU backdoors so far:

TL;DR version

Your Intel CPU and Chipset is running a backdoor as we speak.

The backdoor hardware is inside the CPU/Bridge and the backdoor firmware (Intel Management Engine) is in the chipset flash memory.

30C3 Intel ME live hack:
@21m43s, keystrokes leaked from Intel ME above the OS, wireshark failed to detect packets.

[Quotes] Vortrag:
"DAGGER exploits Intel's Manageability Engine (ME), that executes firmware code such as Intel's Active Management Technology (iAMT), as well as its OOB network channel."

"the ME provides a perfect environment for undetectable sensitive data leakage on behalf of the attacker. Our presentation consists of three parts. The first part addresses how to find valuable data in the main memory of the host. The second part exploits the ME's OOB network channel to exfiltrate captured data to an external platform and to inject new attack code to target other interesting data structures available in the host runtime memory. The last part deals with the implementation of a covert network channel based on JitterBug."

"We have recently improved DAGGER's capabilites to include support for 64-bit operating systems and a stealthy update mechanism to download new attack code."

"To be more precise, we show how to conduct a DMA attack using Intel's Manageability Engine (ME)."

"We can permanently monitor the keyboard buffer on both operating system targets."

Backdoor removal:
The backdoor firmware can be removed by following this guide using the me_cleaner script.
Removal requires a Raspberry Pi (with GPIO pins) and a SOIC clip.

Decoding Intel backdoors:
The situation is out of control and the Libreboot/Coreboot community is looking for BIOS/Firmware experts to help with the Intel ME decoding effort.

If you are skilled in these areas, download Intel ME firmwares from this collection and have a go at them, beware Intel is using a lot of counter measures to prevent their backdoors from being decoded (explained below).

Chip names

[ledow]

I gave up trying to understand chip names and model numbers a long time ago.

GPUs and CPUs are the worst - I have absolutely no clue whether a particular number / model is better / worse than any other.

I let my suppliers deal with it - I tell them what I want, they send me a spec, I google to ensure the chip numbers do what I want in terms of core-speed, number of cores, etc.

It's not hard to come up with a sensible numbering / naming system, but if Intel didn't have a page for every chip that just says number of cores, speed, etc. then I'd have absolutely no clue. Changing it to colours isn't helping matters either - that just reeks of marketing where everyone thinks they need to have "Gold" rather than "Silver" when there's probably little gain for most people.

For the same reason, I stopped buying separate CPUs and motherboards many years ago and nowadays I don't even tend to buy PSUs etc. separately. Because the combination needs to be correct and I'm not going to waste my time and effort only to get it wrong.

Everything from CPU sockets, to PSU power draw (don't forget to check the 12V rail!), to PCIe speed,to card profile height - after a while it just gets so boring, and I'm paying people to supply me the gear, so I let them do the legwork.

But the situation for consumers is actually completely the flip of that. People ask me about buying laptops. I say "check it has the ports you want". No point paying a fortune for a laptop that doesn't have enough USB, and if you buy enough USB or whatever you want for it, it'll be fast enough to do what you want nowadays. Even the cheapest gaming laptops are stupendous in specification and able to play anything I have on my Steam account (if my 6-year-old laptop can do it, too!).

Don't care about the numbers, or the exact model of chip, or anything like that. If you want a cheapy thing just for office, buy a cheapy thing just for office. If you want a gamer's thing for high-end gaming, buy something that's pitched at gamers and comes with the Razer gaming mice or whatever. Pretty much, that's a better indicator than faffing with all the statistics - which although I could understand, nobody else does and I just don't have the time to be bothered to do the research.

Don't even get me started on "does AMD graphics card X perform better than nVidia graphics card Y?"
