The three dies are aimed at workstations/enthusiasts, servers and high performance computing respectively. I’m not going to repeat what Johan already posted, but it is a really good read if you have a chance to look through it. Unfortunately anything over 6-core loading reduces it down to that lower 3.0 GHz mark, whereas single threaded speed is up at 3.5 GHz. Ultimately it is up to the motherboard to implement which turbo modes and P states are in use, and on the consumer line we often find motherboards using a form of ‘MultiCore Turbo’ (read our explanation here). If the E5-2697 v2 was put in this position, we would have 12 cores at 3.5 GHz, ready to blast through the workload. With this CPU the droop is pretty massive -which caused a blue screen on boot - OK, I've not set LLC so trying to cater for the droop with extra v-core. Dont you think that a 262.000 core server and 100s of TB of RAM sounds more like a cluster, than a single fat SMP server? And why do the UV line of servers focus on OpenMPI accerators? OpenMPI is never used in SMP workloads, only in HPC. Intel processor numbers are not a measure of performance. Processor numbers differentiate features within each processor family, not across different processor families. See http://www.intel.com/content/www/us/en/processors/processor-numbers.html for details.

Again, only partially true. The costs and stuff is correct, but the assumptions that you're writing about is incorrect. SMP is symmetric multiprocessing. BY DEFINITION, that means that "involves a multiprocessor computer hardware and software architecture where two or more identical processors connect to a single, shared main memory, have full access to all I/O devices, and are controlled by a single OS instance that treats all processors equally, reserving none for special purposes." (source: wiki) That means that it is a monolithic system, again, of which, few are TRULY such systems. If you've ever ACTUALLY witnessed the startup/bootup sequence of an ACTUAL IBM mainframe, the rest of the "nodes" are actually booted up typically by PXE or something very similiar to that, and then the "node" is ennumerated into the resource pool. But, for all other intents and purposes, they are semi-independent, standalone systems, because SMP systems do NOT have the capability to pass messages and/or memory calls (reads/writes/requests) without some kind of a transport layer (for example MPI).

Types, maximum amount and channel quantity of RAM supported by Xeon E5-2697 v2 and Xeon E5-1620 v2. Then getting on with a stability test in P95 (or similar) I think to myself I can get the v-core down a fair bit more and get rid of some droop that caught me offguard which was as much as 0.075v so from 1.250v in BIOS it would droop to 1.168v at the lowest which I thought was the cause of a blue screen at 1.175v in BIOS which may have caused the v_core to go down to 1.125v or not far from that hence a crash on boot.Technological solutions and additional instructions supported by Xeon E5-2697 v2 and Xeon E5-2695 v2.

At the ultra-high-end of any CPU range, we can see a fight for cores against MHz to remain within the thermal design power limitations. Users can spend their money on more cores, which benefits parallel computation, or focus purely on MHz for single-threaded throughput. The downside of moving to higher MHz is usually efficiency, so the gains might not be as linear as expected. Single processor LGA2011 Xeons are under the title of E5-16xx v2. Dual processor system capable Xeons are E5-26xx v2, and quad processor system capable Xeons are E5-46xx v2. As Johan pointed out in his excellent dive into the improvements over the older architecture , these CPUs come from three die flavors:

So in the BIOS v-core @ 1.250_v but with the droop it goes to 1.200v_1.184_v_&_1.168v that is quite a big swing which caught me by surprise.

PCIe version Intel’s roadmap goes through all the power and market segments, from ultra-low-power, smartphones, tablets, notebooks, desktops, mainstream desktops, enthusiast desktops and enterprise. Enterprise differs from the rest of the market, requiring absolute stability, uptime and support should anything go wrong. High-end enterprise CPUs are therefore expensive, and because buyers are willing to pay top dollar for the best, Intel can push core counts, frequency and thus price much higher than in the consumer space. Today we look at two CPUs from this segment – the twelve core Xeon E5-2697 v2 and the eight core Xeon E5-2687W v2. As pointed out numerous times before, that link is you cite is a decade old. SGI has moved into the SMP space with the Altix UV series. Continuing to use this link as relevant is plain disingenuous and deceptive. You think that HPC- Altix will after some development, be superior to Oracle and IBM's huge investments of decades research in billions of USD? Do you think Oracle and IBM has stopped developing their largest servers?"Kevin G - Wednesday, March 19, 2014 - link "That means that it is a monolithic system, again, of which, few are TRULY such systems.

I don't know what board you are on ------but if it is a good Asus board.......with the BIOS......(MSI may do this I don't know).

Firstly I would like to say a big thank you to GIGABYTE Server for the opportunity to test these CPUs in their motherboard, the GA-6PXSV3. This motherboard is the focus of a review at a later date. Some enterprise CPUs are also designed to speak to other CPUs in multiprocessor systems. On the Intel side, this means a point-to-point QPI link between each CPU in the system. Johan and I have recently tested several multiprocessor systems [ 1, 2, 3, 4] and as such these features develop over time, cost R&D, and are focused purely on the enterprise sector. It'll be interesting to see what IBM does with their next generation of hardware as the GX bux is disappearing.

In terms of my testing at AnandTech, the i7-4960X represents the standard enthusiast processor that blitzes our benchmarks, and thus an opportunity to test something potentially faster is always welcome. Anyway after attempting to alter load line calibration the system would not boot at all and trying to alter the previous 1.250v resulted in hours of wasted time and no result apart from 1.240v and no answer to the v-droop which also caused a v-rise on idle.
