In the past week, Intel has launched a new halo CPU - its highest-performing multi-core CPU for multi-socket mission-critical servers, the Xeon E7-8894 v4. The new processor is based on the Broadwell-EX die and has approximately a 200 MHz higher base frequency than its direct predecessor, released in Q2 2016. Intel said that the new CPU has set a number of records in various benchmarks. Intel’s customers interested in the chip will also have to pay a record price too.

The flagship Intel Xeon E7-8894 v4 processor features the Broadwell-EX XCC (extreme core-count) die and has 24 cores with Hyper-Threading technology, 60 MB of L3 cache, 165 W TDP, a default frequency of 2.4 GHz and a turbo frequency of up to 3.4 GHz. Like other Broadwell-EX XCC CPUs, the new chip has quad-channel DDR3/DDR4 memory controller support and can manage up to ~3 TB of DRAM per socket (when used in conjunction with four Jordan Creek 2 scalable memory buffers). The CPUs are also equipped with 32 PCIe 3.0 lanes and three 9.6 GT/s QPI links for multi-socket environments.

Intel’s multi-core Xeon E7 processors are designed for various heavy-duty servers with four, eight or more sockets (to support more than eight sockets special third-party node controllers are required). Such mission-critical machines typically to be available 24/7/365 and this is why the Xeon E7 v4 and the Broadwell-EX range has a host of various RAS (reliability, availability, serviceability) features. The Xeon E7-8894 v4 CPU has exactly the same set of capabilities as its direct predecessor, the Xeon E7-8890 v4 released last year.

Intel claims that due to increased default frequency (and obviously because of the core count in general), the Xeon E7-8894 v4 sets a number of performance records in various general, server, HPC, big data analytics, business processing, database and other benchmarks, such as SPECint_base2006, SPECompG_2012, and so on.

The Intel Xeon E7-8894 v4 processor carries a tray price of $8898, which is the highest price of an Intel mass-produced CPU ever. Its predecessor on the top spot in the range, the 24-core Xeon E7-8890 v4 (which runs at 2.2 GHz) is priced at $7174 and still sits at its original tray price. As always, there are customers willing to pay such sums of money for server CPUs that deliver certain levels of performance. Moreover, there are workloads that benefit from a +200MHz (9%) performance increase so significantly (from a financial point of view to the owners of the machines) that it justifies paying extra 24% (or $1724) for a 200 MHz frequency increase (provided that this is the only advantage that this CPU has over the E7-8890 v4).

We've asked Intel to disclose the official per-core turbo numbers for comparison to their other chips, as well as a full range of DRAM support depending on memory type and memory density. We will update this news piece as we get more information.

    ^ This.

    Even if it doesn't hold value, the people buying these particular chips are not the kind of people who will be looking to recover $100 in five years from them. And especially not in a single chip config.

    At best they'll send them to a recycling company (who will mark them up significantly) or an engineer will swipe them as the server is decommissioned and give them to his friends or use them himself.

    E3 and E5 generational equivs will be dime a dozen, but not E7s.

    You must realize that a) this isn't a LGA2011 socket and will not drop into a single easily available motherboard on the market b) when these do (if ever) become available on ebay, regardless of CPU cost the motherboard will probably still be $600-800 at least - not including ram, a power supply with 8x EPS connectors, or the rest of the server. These will never be in consumer set-ups except for very fringe cases (engineers that took home decommissioned gear). That has been the case with the Itanium processors of the past, and all past E7 generations. It is simply in another league that is beyond what consumers deal with. And by the way, if you did ever manage to get all of the above for less than the price of a car, you will still have to pay a small fortune to power it all relative to what a normal home uses.

    According to Intel (but what do they know) it's a LGA2011, may be some BIOS issues on most boards though.
  • Notmyusualid - Saturday, February 18, 2017 - link

    It should drop in fine, in my opinion.

    FCLGA is just a more full name of socket, means Flip-Chip LandGridArray. So all of Intel LGAs are FCLGAs.

    Here is my m/b taking all sorts of Xeons:

    And about the cost - yes, I've spent THOUSANDS on my machine.
  • fanofanand - Monday, February 20, 2017 - link

    That list doesn't include any E7's, which supports the point he was making.
  • r3loaded - Monday, February 13, 2017 - link

    They missed a trick, should've priced it at $8894!
  • FatalError - Monday, February 13, 2017 - link

    I guess it is 8894 + (v)4
  • Ariknowsbest - Monday, February 13, 2017 - link

    How will it stack up against 127 G4560 cluster that could be a interesting story.

    Lmao, world domination.
