Intel Lakefield deep dive: the first x86 hybrid CPU
- wronglebowski 6y agoNeeding to manufacture and assemble several components in this fashion must be awful for yields. I'd imagine AMDs chiplet process is much more forgiving.
- jagger27 6y agoThis type of design seems very unforgiving to defects. I think the only place they can get away with a bad core is in the GPU portion. Mind you it’s pretty small at 82mm^2.
- mobilio 6y agoStill waiting 7nm process...
- williadc 6y agoHave you seen a 10nm product from Intel with your own eyes?
- OldHand2018 6y agoThe current MacBook Air is 10nm. While I've never actually seen one with my own eyes, I certainly believe that they exist. https://ark.intel.com/content/www/us/en/ark/products/196586/intel-core-i3-1000ng4-processor-4m-cache-up-to-3-20-ghz.html https://ark.intel.com/content/www/us/en/ark/products/196586/... https://ark.intel.com/content/www/us/en/ark/products/196589/intel-core-i5-1030ng7-processor-6m-cache-up-to-3-50-ghz.html https://ark.intel.com/content/www/us/en/ark/products/196589/... https://ark.intel.com/content/www/us/en/ark/products/196596/intel-core-i7-1060ng7-processor-8m-cache-up-to-3-80-ghz.html https://ark.intel.com/content/www/us/en/ark/products/196596/...

- dyingkneepad 6y agoAny Ice Lake processor, available in many different laptops, from all the major OEMs. I own one.
- aseipp 6y agoYou've been able to buy Ice Lake laptops since late last year. So I'm not sure if this is supposed to be a "gotcha", because it's not a good one.
- fomine3 6y agoIce Lake lacks vPro feature weirdly so some laptops for business (like ThinkPad) don't adopt Ice Lake.
- agumonkey 6y agoI believe intel marketing teams will sweat a lot in the coming years.
- onde2rock 6y agofrom the conclusion : As far as Lakefield goes, this first generation is going to be a rough challenge for Intel – they are pitching a low performance product in a high-cost segment based on technology Yeah, looks like the power of four atom core in an high end ultrabook is gonna be a though sale.
- OldHand2018 6y agoHonestly, I think it is fascinating that Samsung is selling a laptop where you choose between an 8-core heterogenous ARM chip and a 5-core heterogeneous x86 chip, both running Windows. With the built-in LTE, it seems like the ultimate niche computer.
- jschwartzi 6y agoLTE is plenty fast for most business tasks. I have an LTE modem in my laptop and can pull it out in a busy airport and get work done even online. At LTE speeds you probably don't even need Wifi except as a way to get on the local network.

- joshstrange 6y agoA bit random but I'm hoping that Apple will be adding an LTE modem or at least offering it on their new ARM "Apple Silicon" devices. I wish they would do that as well as having something like "internet modes" so apps could check if they should try to use less bandwidth or can use as much as they want.
- nikanj 6y agoWould be beautiful in EU with $20/mo unlimited LTE, and horrible in Canada with $50 for 5 gigs, overages at $30 per gig
- chx 6y ago> there might be a need for a high power, high performance design where cooling is of no consideration Ha, there's a reason IBM z chips were the first commercial CPUs to break the 5GHz barrier with the zEC12 at 5.5 GHz back in 2012. 300W CPU, who cares, it's going to get a tailored water cooling system anyways in a tailored chassis. Cooling is one of the lowest priority problems when designing a mainframe CPU ...
- randyrand 6y agoWell, you still need to prevent it from melting. Coefficients of heat transfer are not infinite.
- AnimalMuppet 6y agoFor a mainframe, you could probably get away with using liquid nitrogen if you needed to.
- rbanffy 6y agoSadly, IBM has not the same penchant for striking design as Seymour Cray had. Well... Their quantum computer is quite striking. I wish they did that with the more mundane machines.
- staycoolboy 6y ago> Cooling is one of the lowest priority problems when designing a mainframe CPU That's not true at all. Next to power deliver, power removal--aka HVAC--is next in line of recurring costs (after one-time costs of building the facility and the initial server BOM). For example: https://perspectives.mvdirona.com/2008/11/cost-of-power-in-large-scale-data-centers/ https://perspectives.mvdirona.com/2008/11/cost-of-power-in-l... Unless by "mainframe" you mean specialty compute-server farm for a supercomputer (with massive IO) then perhaps.
- fomine3 6y agoIBM z chip is for mainframe and it's too expensive and normally not massively scaled out compared to cloud servers.
- Traster 6y ago>Intel has paraded its new ‘Lakefield’ processor design around the press and the public as a paragon of new processor innovation. Inside, Intel pairs one of its fast peak performance cores with four of its lower power efficient cores, This is Intel in a nutshell. That was an innovation ARM made a decade ago. So why in the hell is Intel marketing touting it as Intel innovation. They clearly have some understanding of their customer base as morons. The atom cores are basically an expensive failure, doing a bad job of immmitating their larger cousins and a great job of reminding everyone that Intel hasn't designed a new CPU architecture since Itanium.
- IanCutress 6y agoRead the full sentence. It includes the fact that the die stacking is also an innovation, and using them together is an innovation.
- sitkack 6y agoThose are mechanisms that enable innovation, in and of themselves, they are a curiosity. This moves the needle zero when it comes to competing with AMD. I believe Intel could do it, but they would have to figure out what they really want.
