Xeon E5-2600 v2 series brings Ivy Bridge-EP to servers, workstations

Last week, Ivy Bridge-E premiered in a trio of processors aimed at Intel’s high-end X79 desktop platform. Today, similar silicon dubbed Ivy Bridge-EP heads to enterprise aboard the new Xeon E5-2600 and E5-1600 v2 product families, bringing more cores, more cache, higher memory speeds, and virtualization improvements to server and workstation systems with one and two sockets.

The server and workstation chips packs as many as 12 cores and 24 threads, up from 8 cores and 16 threads in Sandy Bridge-EP. The L3 cache has ballooned from 20MB to 30MB, and the peak speed supported by the quad-channel DDR3 memory controller has risen from 1600MHz to 1866MHz. Intel has also added APIC (Advanced Programmable Interrupt Controller) virtualization, a feature that purportedly shrinks virtualization overhead by up to 4%.

The original Xeon E5-2600 and E5-1600 families are based on two different Sandy Bridge-EP dies. One has four cores, and the other sports eight. (Two of those eight cores are disabled for the six-core parts.) The new Xeon E5-2600 v2 and E5-1600 v2 lineups features three versions of Ivy Bridge-EP: one with six cores, another with 10, and a 12-core monster. That flagship uses a different internal ring arrangement and more complicated routing to squeeze a dozen Ivy Bridge cores onto a single piece of silicon.

Here’s a breakdown of the functional differences between Sandy Bridge-EP, which powers the Xeon E5-1600 and E5-2600 families, and Ivy Bridge-EP, which drives the v2 lineups. Keep in mind that Sandy is built on a 32-nm process, while Ivy is manufactured using Intel’s state-of-the-art 22-nm fab tech with tri-gate transistors. The specs below apply to the E5-2600 and E5-2600 v2 series, which are for two-socket systems; Intel also offers E5-1600 and E5-1600 v2 chips for single-socket workstations.

Intel claims Ivy Bridge-EP delivers "up to 35 percent higher performance on average over previous generation Intel Xeon processor-based servers across a broad range of benchmarks."

The Xeon E5-2600 v2 family includes 18 processors aimed at two-socket servers. Those processors have 4-12 cores, TDPs of 60-150W, and base clock speeds ranging from 1.7GHz to 3.5GHz. The two lowest-end variants lack Turbo Boost and Hyper-Threading, but the others have those features enabled. Prices range from $202 for the most pared-down model to $2614 for the top-of-the-line 12-core, 24-thread part.

Intel has also rolled out four new processors for workstations. The E5-2687W v2 is for dual-socket configs; it has eight cores, a 3.4GHz clock speed, and a 150W TDP. The other workstation chips make up the E5-1600 v2 series and are aimed at single-socket setups. They have only 4-6 cores and thermal envelopes up to 130W—but they do run at a slightly speedier 3.5-3.7GHz. Turbo Boost and Hyper-Threading are enabled across the workstation range.

    I think Intel should show AMD how to make a real 8 core CPU that uses 200 watts off this from this WS chip just make it a 200 watt chip and unlock it.

    E5-2687W v2 K chip with 8 cores 3.4 GHz 20 MB 150 Watt core CPU that uses 200 watts of power make that 3.4ghz 3.8 with 4.2 turbo…whatever it takes to get to 200 watts out of the box. Any more then 8 cores then high cpu clockspeeds even with a 200 watt cap would be around 3.0-3.2 with 10 cores.

    Wonder what clockspeed Intel could give us with a 200 watt cap with the 8 core CPU

    Ill take 3 for all my systems gaming rig, 2 HTPC’s you name it:) Joking about the HTPC’s Ill just use i7 4770k’s for those after I hit the lottery

      a year ago when the rumors of these chips were floating around i was dreaming of exactly what you mentioned – a 8/10 core consumer version for X79 systems

      but instead they gave us the overpriced 6 core thats pretty much the same as the sandy-e 6 core 🙁

      anyways i would buy one of those chips for sure – i really dont care at all if it used 200W i would still try and overclock it even more 🙂

        Biggest issue with Ivy-E isn’t that it isn’t much of an upgrade CPU-wise over SB-E- Ivy wasn’t an upgrade over SB either- but that X79 still sucks. Intel could have fixed that in a jiffy, but didn’t.

        That doesn’t make Ivy-E any less desirable for those still on a consumer platform like myself (2500k 4.5GHz on Z68) that could use the extra cores, but it doesn’t make much sense for someone already on a 32nm >2 RAM channel platform.

        An eight-core version, unlocked, would be awesome- and it would be really cool if Intel had just made the Ivy-E platform out of hex-core and octa-core parts, harvesting to get the hex-cores, and replaced the quad-core and hex-core parts they actually released at the same price-points. And then welded the Z87 southbridge to the X79 northbridge, and called it a day.

        Even better would be skipping Ivy for Haswell, same core specs mentioned above, with a new socket to support a cut-down HD IGP so that they can attach TB ports to it, along with the Haswell southbridge and so on. Oh, and higher clocked, lower power, and lower latency ECC support. Skip the FB-DIMMS, but give us workstation class RAM for our workstation class CPUs and boards, damnit! ECC would be even more useful for overclockers!

      Intel has no economic incentive to do this, because the i7-X4xxx parts are just recycled Ivy Bridge-E chips that didn’t make the Xeon cut. 8/12 core Xeon chips are build on Ivy Bridge-EP which is larger version meant for enterprise-tier only.

      Holy hot griddles, Batman!

      You were right sir. Now can you explain why I want 4 of these in a server? I’m thinking maybe if we get a dozen guys willing to donate a kidney’s worth of money for hardware upgrades, we just might be able to finish the whole folding project by Thanksgiving, and maybe figure out how to make turkeys with 6 legs and 4 wings to boot.

      Come on guys, who’s in?

        These should only be 2 socket, but if we’re going to go for it why not go for the E7-4870 (10 core) in a HP 980 G7 (8 socket!). . 80 cores, no waiting. Holy folding!

          Considering the current 4P platform is still on Nehalem, a 2P workstation based on the 12-core Ivy-EP should be interesting.

            [url<]http://ark.intel.com/products/64622[/url<] The Sandy Bridge-EP E5-4600 series would like to have a word with you.

    YES!! When I went with socket 2011 for my dual socket rig, I did not expect Intel to come out w/ a 10 or 12 core cpu on the same socket. Now I have an upgrade path from 8 core to 12 core in the future.

        So what’s your point?

        TR usually includes the price list with announcements/reviews, so why not this time?

          It is definitely some heavy jingle.

    I’ve been watching these for a while now.

    Hoping the 10c E5 comes in at under £1000 (~$1500) as the new sub-£1000 workstation champ.

    Oh, I missed the word purportedly the [i<]first[/i<] time.
