Power consumption

By the virtue of the impressive 22nm Hi-K metal-gate tri-gate 22nm CMOS with 9 metal layers, Intel has been able to increase the maximum core count by 50% (15 vs 10) and the clockspeed by 17% (2.8GHz vs 2.4GHz) while the TDP has only increased by 19% (155W vs 130W). Intel claims that the actual power usage of the new flagship E7, the 155W 4890 v2, is actually lower than the previous 130W TDP Xeon E7-4870 at low and medium loads.

At maximum load, Intel claims you get about 50% higher power consumption for twice as much performance. At idle and low loads, it seems that the 155W Xeon 4890 v2 is a lot more efficient. That makes sense considering the improvements in idle/low load power use we saw with Sandy Bridge and then Ivy Bridge over the earlier Nehalem/Clarksfield offerings on desktops and laptops; it's taken some time, but the big servers are finally seeing the same improvements with Ivy Bridge EX.

    Minor correction on the Dell E7-4890 SAP benchmark, which was done on SUSE Linux Enterprise Server for SAP Applications:

    you should opt for ubuntu 12.04. "real" databases are approved only for LTS versions, and 12.04 is the latest.

    Page 10 does not contain the Linux Kernel Compile time benchmarks.

    The web engine did something weird...I restored the page

    Very thorough review, which is what I've come to expect from Anandtech! I am interested but not very knowledgeable about the server side of computing, so this definitely filled me in on a lot of the facets of that area. Thanks for the writeup.

    By the way, the "Linux Kernel Compile" page is blank, as bji noted.

    Thx. A glitch in the engine made it delete a page. Restored.

    While the revenue are high, just how many unit are shipped?
    I have been thinking if Intel would move Mobile First, meaning Atom, Tablet and Laptop Chips all gets the latest node first, which are low power design. While Desktop and Server will be a Architecture and Node behind. Which will align the Desktop and Xeon E3 - E5 Series.

    But it seems the volume of Chips dont quite measure out, since the top end volume are far too small? Anyone have any idea on this.

    I believe the statement "Still, that tiny amount of RISC servers represents about 50% of the server market revenues." should read "Still, that tiny amount of RISC servers represents about 50% of the high end server market revenues." Stated differently, from a revenue perspective Intel is #1 vendor in the high end segment even though it has less than a 50% market share. Server orders are placed with vendors, not architectures. Intel has fought an uphill battle to access the high end market and it is costly. However, if Intel can amortize its development costs over a larger revenue base than any competitor, it is well positioned to maintain it's share acquisition momentum.

    @Johan

    Very nice review, I would like to see more benchmarks between E7 v2 vs RISC processors because I think the real competition is there.

    Older Intel and AMD servers are not real competition for IvyBridge-EX.

    It would be interesting when POWER8 is out, to give us the new figures of 8 socket benchmarks and if there is any progress on more 8+ sockets for Intel E7 v2 (built by Cray and other vendors)

    I think that E7 v2 (I don't know about older vendors) can be placed in up to 32-socket systems - not natively of course.

    Older Intel systems are competition, because these kind of servers are not replaced quickly. If a new generation does not deliver substantial gains, some companies will postpone replacement. In fact, very few people that already have a quad intel consider the move to RISC platforms.

    But you have a point. But it is almost impossible for us to do an independent review of other vendors. I have never seen an independent review, and the systems are too scarce, so there is little chance that we can ask a friendly company to borrow us one.
