    Intel's next-generation Core i7 "Haswell-E" HEDT (high-end desktop) processor lineup, slated for later this year, accompanied by the company's X99 Express chipset, will launch at three price-points, predictably, succeeding the current Core i7-4820K, i7-4930K, and i7-4960X. The platform will herald a new LGA socket, which will have 2,011 pins, but will not be compatible with current LGA2011 platforms based on the X79 Express chipset. That's because "Haswell-E" will be among the first client platforms to support DDR4-SDRAM memory. All Haswell-E chips will support DDR4-2133 MHz out of the box.

    Moving on to the actual lineup, and it begins with the Core i7-5820K. This is a six-core chip, and a welcome departure from Intel's sub-$400 HEDT chips being quad-core. Whether it supports HyperThreading, is not known. You still get 6 physical cores to plow through work. The chip also features a staggering 15 MB of L3 cache, clock speed of 3.30 GHz with a couple of notches of Turbo Boost, and a quad-channel DDR4 integrated memory controller. Oh, and there's the unlocked BClk multiplier. Sounds too good to be true for a sub-$400 chip? Here's the catch - its on-die PCI-Express Gen 3.0 root complex will have fewer lanes. It can spare just 16 + 8 lanes for discrete graphics cards. For boards with three long x16 slots, that would mean x16/NC/x8, or x8/x8/x8, with an additional x4 link.

    Next up, is Intel's $600-ish Haswell-E HEDT chip, the Core i7-5930K. Like the i7-5820K, this is a six-core chip, but could feature HyperThreading. It has the same 15 MB L3 cache, and quad-channel DDR4 IMC. It offers higher clock speeds, of 3.50 GHz. Unlike the i7-5820K, it features a full-fledged PCIe root complex, giving out two x16 links, and one x8 link. This would be ideal for 4-GPU setups in which the two x16 links split up as x8/x8/x8/x8, with a fifth long slot still having an x8 link, to drive high-bandwidth SSDs.

    Leading the pack, at a four-figure price, will be the Core i7-5960X. This is an eight-core chip with HyperThreading, enabling 16 logical CPUs. The eight cores are cushioned by a massive 20 MB L3 cache. The chip runs at lower clock speeds than its smaller siblings, at 3.00 GHz, and features the same 40-lane PCI-Express root complex as the i7-5930K.

    All three chips feature TDP rated at 140W.

    Gimping PCI-E? I would rather have the 5820k not be a k and not have an unlocked multiplier instead of having fewer PCI-E lanes.

    Real question: How legitimate do you really think the source is? Also no ECC support? That's weird for HEDT.

    If the cheapest 8-core CPU will really cost north of 800$, intel will tear my year-long anticipation apart.

    Looks pretty accurate to me....

    Most HEDT platforms of the past don't support ECC, that's usually reserved for the Xeon platforms.

    It looks like an expensive platform, we cant even use our old memory anymore and no doubt DDR4 will be expensive at first. Well, hopefully the performance is there, I'm prepared to pay if the performance is there.

    You could always get a board with an 8c/8t Atom? :p
    I know what you mean though, not that most consumers needs that kind of multithreaded power.

    Considering the price difference between the 5820K and 5930K I am 100% sure that the 5820K doesn't have Hyper Threading.

    I stand corrected. The i7s don't support hardware ECC on memory, but if you threw a Xeon in the same board, it would. I suspect if you put ECC DIMMs in and it worked, it probably wouldn't be doing hardware level ECC so it would probably slow down quite a bit.

    Let me think... mm 1300$+ :D No point to be "just" 1000$ as 6 core. ;)

    The 3820 3930K 3960X 4820K 4930K and 4960X don't support ECC so that's normal for HEDT as of 2011.

    970/980(X)/990X also doesn't have ECC as I know.

    The first Intel HEDT CPU where the higher price tag for the X-version is kind of justified with 2 additional cores? Count me in!

    Wow. Huge correction on my part. I saw ECC settings on one my AMD rigs, not my Intel one. I clearly need to drink my coffee before posting. :slap:

    Finally 8 cores (+HT). It seemed like we're gonna be stuck with quad cores forever...

    So it does now make sense to buy the X CPU. You've finally grasped it Intel (at our expense though :p).

    Intel :banghead:
    Before that we had
    x930K HT + non crippled PCIe + abit more cache + 2 more cores comparing with x820K
    x820K HT + non crippled PCIe

    Now x930K will have same cores ammount and so that people would still buy it over x820K they'll cripple x820K beyond the belief taking out HT? *uck you Intel!

    So we don't have $600 8 core + HT chip and $400 6 core + HT, there is no point to touch this overpriced $1000 CPU to have real 8 cores and no point to upgrade the lesser ones.

    The lack of competition from AMD is saying its word.

    I'm all the time saying that YOU should be very careful what you are buying not to cause monopoly.

    The same would happen if you continue to buy nvidia videocards and make AMD even weaker. No one will benefit in the long term.

    The last thing I need is a $1,000+ 8 core CPU with all the necessary trimmings. That said, I fully intend to build such a system. Desire is all I have to justify such a build, but that is sufficient in and of itself. Most importantly, though, is my wife has actually encouraged me to go "uptown" (we're both 63 btw) so with such a green light as that, who am I to argue?

    Seriously, I'm more curious than anything about how well MSFT Flight Simulators 9 & 10 will run. I probably won't notice anything more than an increase in frames over my current overclocked 4770K. I was a private pilot for 35 years until I failed the physical. Now the PC is the only thing I can fly, so there lies my passion and my obsession to see if each new PC generation can make things just a little bit better.

    I'm planning to build a Z97/4970K system next month (or whenever) and when the Haswell-Es come out, my existing 4770K rig will be handed down to our one of our seven grandkids.

    SOOOO looking forward to playing with some new tech.......Not looking forward to endless post about amd comparisons , prices and the necessity of it.
    :toast: @ Romeg hope to still be doing the same thing when i'm your ag.... level of life experience.

    The more I look at this the happier I am with a 2600k and an Asus P8z77-WS with the PLX chip. I was really thinking about going for a lower end x99 cpu for the more lanes, but if its gimped like that then I simply won't bother.

    The 8-core looks like a strong contender when paired up with a Gen3 PCIe M.2 SSD.

    Skip!!!

    I'll wait until we get up to 8 or 10 cores

    Up to 8 cores you say?
    Did you even read the OP?

    yes I did,

    Not paying 1k for a 8core X

    when the next line up will have K with 8 or 10 cores

    One thing is clear as it has ever been. Intel always hobbles and compromises the entry level in such a way as to make it unpalatable. Limiting the PCIe lanes was unexpected IMO but we knew Intel would do something to make the customer make hard choices between price and performance.

    The mid level having fewer cores then the high-end wasn't entirely unexpected IMO since I was expecting anywhere from (entry level, mid, high-end) (4/8, 6/12, 8/16) (6/12, 8/16, 8/16) (6/12, 6/12, 8/16).

    Currently I have an Intel Core i7 3930K which IMO is a great chip that has served me well for years. The mid level would be what I would typically buy but this time around the entry level is catching my interest if it is a 6 core 12 thread part at ~$300 USD.

    I hear the speculation that the entry level Haswell-E Core i7 5820K wouldn't have HT but that seems a little over the top coupled with the PCIe limitations IMO. Without HT the Haswell-E Core i7 5820K should be named "Core i5 5820K. Cutting the PCIe lanes is going too far but cutting the PCIe lanes and removing HT is really going way, way, wayyyyyy too far. So I am skeptical of this.

    More PCIe lanes is the one thing that many mainstream users would step up to a HED for but since these same people often settle for less in the mainstream its not necessarily like they are losing anything if they go for a Haswell-E Core i7 5820K

    Controlling / limiting monopolies is the the domain of a governing body. Its not the job of individual citizens.

    I thought you would say that it was up to the market to decide. Well, you are part of the market. :)

    I understand you. :)

    You want a 5770K with 10 cores, 20 threads. :) For $350. :)
