Intel Announces 8th Generation Core “Coffee Lake” Desktop Processors
- neverminder 9y agoI'd rather they announced LPDDR4 support at last. It's just ridiculous when your average smartphone technically supports more RAM than your laptop.
- BillinghamJ 9y agoLPDDR doesn't seem very relevant for desktop processors, but I do wish they'd get on with it for laptops.
- mrmondo 9y agoAnd ECC as a default
- jkoll 9y ago>Intel
- romanovcode 9y agoThey will not work with standard LGA1151 socket so a lot of motherboard manufacturers are super pissed at this. Not sure how much traction this will get to be honest.
- meritt 9y agoThey use the same physical socket (LGA1151) but are restricting usage via firmware / chipset. Z270 = Kaby Lake Z370 = Coffee Lake
- dugditches 9y agoZ170 boards supported Skylake and Kaby Lake(with firmware updates). Disappointing that those boards won't see the new more cored processors. There's some... interesting power consumption with the latest i9 OC'ed. https://www.eteknix.com/intel-core-i9-7980xe-extreme-edition-review/6/ https://www.eteknix.com/intel-core-i9-7980xe-extreme-edition...
- vmsplice 9y agoOfficially, Z170 won't see Coffee Lake. Unofficially... Let's just say it's possible.
- mcraiha 9y agoIs there some proof you could share? Motherboard manufacturers have been super silent about this.
- vmsplice 9y agoSorry, not really, I've only heard rumours (from a reliable source though). It should be technically possible because coffee lake CPUs were demoed on previous chipsets. I doubt you are going to hear much from the motherboard manufacturers, they're probably more or less obliged to push the Z370. I understood the unofficial part as in not publicly available, at least not right away.
- jandrese 9y agoI miss the days when there was actual competition with chipsets. Intel seems way too keen to put harsh restrictions on their chipsets for anything but their most overpriced chips, especially W.R.T. PCIe lanes and ECC support.
- terminalcommand 9y agoMany people have upgraded to either Kaby Lake or Ryzen. There are rumors that Intel aims people who have not upgraded for more than 5+ years. However the current generation will add two more extra cores with slightly better single-threaded performance for the same price. i7's and i5's will have 6 physical cores and i3's will have 4 physical cores. On multithreaded performance there is a huge capability increase resulting from the extra cores and threads compared to the latest generation. Motherboards are yet to be released, and people are expecting higher prices in the beginning due to a potential increased demand. We'll see what happens.
- muro 9y agoI thought manufacturers would be more happy as people also need to buy the mainboard :)
- drzaiusapelord 9y agoAgreed, I doubt OEM's are pissed. Now they have an excuse to upsell the customer. I imagine the decision to move on or stay with a socket or firmware lock is 50% technical and 50% commercial for Intel. They need to keep OEMs happy and sales flowing. They don't want to just sell CPUs and have end users pop-in new CPUs and lose the support and goodwill of OEMs with mb's and systems to sell. From a marketing perspective this means a new model number, new ads, etc all designed to make last years system obsolete and to bug you into buying the latest and greatest.
- wand3r 9y agoI bet theyre pissed. If it was compatible, people would buy more boards they already designed, now they have to create and manufacture new boards that compete with old stock. Likely, due to AMD some OEMs are having trouble selling intel chipsets in that socket size
- dabockster 9y agoOne of the many things that influenced my decision to build with AMD Ryzen. Sorry Intel, but you slipped up.
- astrodust 9y agoIs it some kind of LGA1151v2? They are really not communicating this very well. The description implies you can drop-in replace a 7700K with something in this series, but apparently not?
- ihsw2 9y agoLGA1151 has some significant limitations (eg: PCIe and memory bandwidth), I am certain that Intel did not make this decision lightly. Z370 are quite different from Z270 and this will cause confusion for many. Perhaps Intel is banking on the Z370 chipsets being the Intel equivalent of AMD's AM4 -- a chipset that sees support until the introduction of DDR5 memory. Nonetheless, the Z270 chipset being unceremoniously EOL'd is an unpleasant occurrence for many (including ODMs). To answer your question -- it is most definitely not a drop-in replacement. While they may use the same socket, they are not interchangeable.
- keldaris 9y ago> Perhaps Intel is banking on the Z370 chipsets being the Intel equivalent of AMD's AM4 -- a chipset that sees support until the introduction of DDR5 memory. Hah, you wish. It's already been leaked [1] that next year's 8 core desktop CPUs will require a yet another chipset - the Z390.

- ihsw2 9y agoWell then, this is troublesome. Hopefully AMD's next-gen chipsets (ie: the AM4 4xx chipsets) maintain backwards compatibility with current-gen CPUs. While AMD has been straight-forward about current-gen chipsets (ie: the AM4 3xx chipsets, A320/B350/X370) supporting all manner of AM4-compatible CPUs until AM4 is EOL'd, it is not yet clear whether next-gen AM4 motherboards will support current-gen CPUs. Probably not.
- std_throwaway 9y agoDoes it support ECC memory?
- binarycrusader 9y agoNo, that remains a Xeon feature.
- mrmondo 9y agoAnd on low end i3 chips
- acqq 9y agoYes, an example from 2017: https://ark.intel.com/products/97455/Intel-Core-i3-7100-Processor-3M-Cache-3_90-GHz https://ark.intel.com/products/97455/Intel-Core-i3-7100-Proc... The latest i5 or i7 with ECC were introduced in 2014. Now, does anybody know why i3 but not i5 or i7?
- spoonspoon 9y agoProbably because there are no i3 equivalents in the Xeon line (no dual core Xeons) and Intel wants a low-end ECC supporting CPU. Keep in mind that for at least the last couple generations, even though Celerons, Pentiums, and i3s support ECC you must use a server chipset like the C23x or C22x to actually get ECC on those CPUs.
- undersuit 9y agoIntel segments ECC support by Chipset and only the Workstation chipsets get ECC support. I recall reading somewhere that Intel was also ceasing the support of i3s and server chipset support and the Intel Ark page supports this: https://ark.intel.com/products/126688/Intel-Core-i3-8100-Processor-6M-Cache-3_60-GHz https://ark.intel.com/products/126688/Intel-Core-i3-8100-Pro...
- snaky 9y agoNo FPGA onboard either.
- wolfgke 9y agoDo they support AVX-512?
- awill 9y agoyes
- wolfgke 9y agoAt least such a support is not listed on > https://ark.intel.com/compare/97129,126684 https://ark.intel.com/compare/97129,126684 (only AVX 2.0 is).
- aarongolliver 9y agoI think they confused Coffeelake with the new Skylakes
- stagger87 9y agoI don't think so. I think we are stuck with the SkyX and XeonW (whenever that becomes available) for AVX512.
- deleted 9y ago[deleted]
- ju-st 9y agoThe newest Xeons have a higher performance when you use AVX2 instead of AVX512 because of the low clock when using avx512 instructions (source in German: https://www.heise.de/ct/ausgabe/2017-20-Von-Suenden-Fehlern-und-Erfolgen-3828728.html https://www.heise.de/ct/ausgabe/2017-20-Von-Suenden-Fehlern-... )
- slededit 9y agoThe first gen is usually slower and a prototype so software can get written. AVX2's scatter gather instructions were similarly slower initially.
- CptBland 9y agoThat's my kind of lake. I mostly just find it interesting that TSMC seems to have leapfrogged Intel in fabrication processes quite solidly.
- ploxiln 9y agoNot at all - the single "nanometers" figure has been very heavily fudged since 22nm, and different vendors fudge it differently. They're all struggling mightily at these scales (which is understandable). The number is bluster for the market (which I have less sympathy for).
- wolf550e 9y agosee the numbers in the reply here: https://forums.anandtech.com/threads/how-do-global-foundries-samsung-14-nm-tsmc-16-nm-and-intel-14-nm-all-compare.2487545/ https://forums.anandtech.com/threads/how-do-global-foundries...
- jordigh 9y agoAny hope of getting non-backdoored hardware ever again?
- 0xbear 9y ago40 PCIe lanes is good news for those of us in need of reasonably priced quad GPU workstations. I’m really looking forward to this.
- spoonspoon 9y agoPretty sure still only 16 lanes from the CPU.
