    If CFL on 1151 is above 95W TDP the chip is dead on arrival. Can you imagine someone sticking one of those into one of those cheapo ECS or Biostar H210 (310?) motherboards? Yeeeek... D:

    The $1700 SKU? That was fairly trivial to figure out, wasn't it.

    Also, i am 100% certain that 5122 is 3.6Ghz single core turbo.

    It's $1.3K, for the Server variant. I have no idea what the turbo actually is. Anyway, I said insight - not factual absolutes.

    Remember Tdp is not the actual power consumption. It's specified for thermal dissipation reasons. Its related somewhat to power but not the actual power draw. The power draw is usually less on average.

    Doubt very many people are going to buy a top of the line brand new hex core and not know what motherboard it requires.

    I don't get this discussion about mb's. When I test a heatsink,it really doesn't matter what motherboard a cpu is inhabiting. We are far more interested in the heatsink or the aio.

    The Gold 5122 is an XCC-derived 4C SKU similar to E5-2637v4 and E7-8893v4. It forms a niche SKU that offers the high end platform features and full cache size with low core count. Basically a way to recycle defective dies.

    Motherboards should deliver sufficient power for the processor; see: AMD FX-9370 and 9590, and Intel Xeon Phi for LGA. You're right that Intel motherboard power delivery for socket H is being brought up is odd, because few users ever do bring the topic up; hasn't been an important factor in processor performance.

    It's not the delivery that worries me so much as the ability of the VRMs to handle it, especially under load for sustained time periods. There is a reason I haven't given Biostar the time of day since Socket 939...

    So what features is X299 expected to have over X99? I assume its mainly just the new CPU's. PCI-E 3.0, DD4 quad channel, similar number of lanes, M.2. etc. Anything beyond X99?

    That pricing is not what you're going to see on Ark.

    Well, X299 - so it's a 200 series chipset that just supports quad channel and more cores.

    If it is 4 core, then it makes sense. But the rumors (including the post that I quoted) are that it is 12 cores. 12 cores at 3.6 GHz doesn't seem feasible at that price and power level.

    So therefore it means that Intel changed the naming scheme to prevent speculation on the Internet.

    Hoping the 7820X is under $600.

    Thanks for sharing. The 7800X, if priced competitively, would probably be the chip that fits best with most workloads. But the 7820X seems like a really great chip. Intel's chips are cache starved, and this helps that a lot. 28 PCIe lanes will really open up the market for fast drives and devices (having just one M.2 port really hampers people). Plus it is slightly faster than the 7700K. The extra cores may help a few use cases, but I honestly don't think cores are the issue for most people right now (and if cores are the issue, there are already plenty of chips with high core count).

    Very nice turbo clocks on 8C and 10C. Waiting to see the performance and pricing.

    My estimate (not based on knowledge, but instead on how Intel has been pricing their chips, including the i7 extreme which the i9 seems to be a replacement for):
    7900X: $1000
    7820X: $580
    7800X: $400
    7740K: $350
    7640K: $250

    That pricing is too tight for the high margins that Intel aims for with HEDT.

    Anyhow, it looks like they reduced the number of PCIe lanes on the eight core part.

    Yeah, not going to happen. Once you kill your margins, you can almost never get them back. At this point, while Ryzen is good and they are selling them. It still isn't a speedbump to Intel's bottom line. In 12-18 months if Ryzen heads to the stratosphere then they *might* reduce margins a bit. But both are unlikely.

    So they change their branding to i9? That's interesting. Looks like they are doing what they can to make these feel revolutionary and new. They are new and look to be great, but the i9 naming seems unjustified IMO. What is AVX-512 good for?
