    Its worth noticing with the boost clocks. Its unlikely that a stock mainstream part will again run in circles around a HEDT part.

    And now we wait and see if AMD has really forced Intel to adjust their prices or not...

    I'm thinking a 7820x is calling my name if priced competitively with Ryzen. 1800x is ~$500 is I'd pay around that.

    Also AMD is coming in with WhiteRaven and up to 16cores. Intel needs to be competitive in pricing on Skylake X. Their price gouging ends this round

    Any estimate on how AMD's 16C / 32T will be priced (and when that platform will be available)?

    You started drinking early today :p a 4.5ghz boosting octocore extreme edition for $500? That'll be the $1000 SKU all day.

    If any are priced at 1099 or 1199 the answer is no.

    Yeah..I can see the going for $100-200 more than the comparable Ryzen...but if they're in the >$1k range, then we're basically back to the status quo.

    No way in hell an 8 core intel will be double price of an 1800x. Not happening considering Ryzen is competitive and AMD has their HEDT x399 platform

    An 1800x is already as good or better at workload for way cheaper. Intel can't price gouge anymore

    It is about 20% behind the 6950x

    You're comparing to the 6950x which is 10core. The 1800x is ahead of the 5960x in that chart.

    Well they're introducing a new "i9" branding, that's something. Although the 'X' at the end has me worried.
    If Intel doesn't launch a sub-$400 hexcore this year I'm going to throw myself out a window.. I can't justify paying double Ryzen's prices for the same core count unless it's an insane OCer.

    I would suggest a ground level window then. :)

    The 28 lanes on the 6 and 8 core SKL-X is a giveaway that they will be cheap.

    Yeah not sure what to make about it on the 8-core but then if using only 1 GPU (and this is more the way to go these days especially with Nvidia) then that does give flexibility for other tech such as x4 PCIe Optane SSD/x4 PCIe NVME/etc.

    So on one side would be nice to see with extra lanes but then also nice that with 28 lanes should be reasonable price (relative to Intel in past) and that is still a reasonable amount of lanes bypassing DMI 3.
    Just means those going multi-GPU for prosumer or other heavily expanding storage/other solution need to go up the ladder now to 10C but that will more than likely also have adjusted prices.

    Cheers

    You are right, I messed the numbers, sorry by my mistake.

    Note that the 1800x is only 4% ahead in that chart, but 10% behind in games

    Lower clocked Broadwell-E beated Ryzen core for core, not that its any surprise considering Ryzens low IPC. And we can see SKL-X is much more aggressively clocked.

    Turbos up to 4.5GHz and ~10% higher IPC than Broadwell will beat anything R-related in most x86 workloads.

    I think 10% is low set after the L2 change ;)

    Even so, 10% behind in games does not equate to double the CPU price. I would expect intel to be $50-100 more expensive than the closest Ryzen offering.

    With SKL-X you can get the best of all worlds. Cores, IPC and clock.

    10% on stock settings, with one of the CPUs coming with higher clocks than the other. Considering the better overclocking headroom the gap increases to 25--30%.

    Note as well that performance is a nonlinear function of cost. Extracting 20% more performance from silicon costs much more than 20% extra pricing. This rule is based in physical laws and not only affects Intel models. Just check the pricing structure of the AMD R7 models: the 1800X costs about 25% more than 1700X but is not 25% faster.

    Extracting/ improving more than 20% costs more than 20% when the design is at the absolute edge progress or there is no competition. Sky Lake-X is not the end all of designs... not even Sky Lake based Xeons are, the price leaps in Broadwell-X for the extra cores was due to Intel having no competition in that area.

    See how Nvidia and AMD GPUs over the years have tended to cost similarly (and less overall) when offering similar performance. When one GPU is only about 10-20% better than the other brand's GPU then cost is still fairly well capped with a good correlation between how much better the chip and how much more it costs compared to the other brand's product.

    If AMD's "leaked" 16 core design is good enough then Intel will need to pick from one of the three following options with the Sky Lake i9's: 1) lower prices; 2) write off the design as a failure; 3) suborn AMD with anti-competitive practices... again.

    The boost speeds are pretty crazy on some of these processors. Wonder what the 7820X will be priced at.

    If the 7820x overclocks to 5.0GHz consistently and is less than $1k, I'll probably go for it. I have been fighting the upgrade bug for literally years. Through every product cycle I have been more and more impressed with my 2700ks ability to stay relevant.

    The 7820X seems to be around the 600$ mark.

    I would look at more realistic levels so as not to be disappointed.
    4.5GHz all cores when overclocked or a little over if keeping within 24/7 voltage levels.
    Will be able to push 5GHz with Boost 3 on the best core IMO, so sort of there - of course tweaked.

    Cheers

    Or 4) at long last produce a top shelf unlocked product of their own based on LGA3547 that has a high core count, is dual capable and has ECC support....;)

    Hmmm...I figured with 4.5GHz being the stock clock, 5.0GHz was not asking that much...

    It is quite a bit to ask when considering 6C and more in context of these CPU designs.
    That 4.5GHz would be achievable comfortably on air IMO without voltages hitting higher than around 1.3V and more likely under 1.25V for the Skylake-X models.
    IMO anyway, the single core Boost 3 would be tricky to work out as it could be a fair bit above 5GHz *shrug*, but that is not on CFL-S it seems looking at the leak.

    Cheers

    Tell that to AMD with Ryzen which has the worst OC headroom I've ever seen in CPU.

    I guess my old Sandy Bridge has spoiled. I mean if a 6 year old chip and overclock 1.1GHz on 4 cores to 5.0GHz, a new chip should be able to overclock 500MHz to the same speed on 6!...lol

    AMd Ryzen 16 core not too far away I guess. If it is a performer then we shall see a real price war! Intel might become affordable again, or not depending on AMD.

    All Intel wants is high margins 14++ is just the backup plan since 10nm is taking far longer then they like. They will price high and ignore AMD exists until AMD can hurt their sales and even then your likely to see the whole rebate trick again with oem's before they actually lower prices.

    AMD wants high margins too. Whats this idea that AMD is some kind of pro bono company.

    And AMD says nothing is happening in 2017 with the full year outlook. Unless you think AMD is lying with something that would be a criminal offense.

    You really know nothing about the corporate world do you. AMD wants high margins no doubt, but they cant charge more then Intel unless they beat them at every metric and since this a Intel forum I tend to only focus on that company. Intel has never cared what AMD was charging for a processor, Intel has there own internal ideas for that, it only changes when AMD starts eating market share. Yes AMD had a very conservative outlook and that is smart since they launched new video cards, and processor line. You dont want to come under a prediction as Wall Street will punish you for it, if you exceed your prediction you get rewarded. Chrysler alos put out a very conservative outlook when emerging from Bankruptcy and has exceeded all those predictions and there stock value went up. It's all a game I dont think you quite understand yet. Just like losses on the books can hide profits if you know the loopholes, a good accountant can make a world of difference there.
