Apple's 12-inch MacBook lineup is expected to receive a refresh in 2018, and the new machines may use Intel's upcoming 8th-generation 14nm++ Y-Series Amber Lake chips.

Details on the new chips leaked recently from Dell's Chilean site and Romanian site NextLab501, as highlighted by MacRumors forum reader EugW.

Chips appropriate for the 12-inch MacBook include the 1.1GHz Core m3-8100Y, the 1.3GHz Core i5-8200Y, and the 1.5GHz Core i7-8500Y.

Core m3-8100Y
- 1.1 GHz - Base clock
- 2.7 GHz - 2-core Turbo
- 3.4 GHz - 1-core Turbo

Core i5-8200Y
- 1.3 GHz - Base clock
- 3.2 GHz - 2-core Turbo
- 3.9 GHz - 1-core Turbo

Core i7-8500Y
- 1.5 GHz - Base clock
- 3.6 GHz - 2-core Turbo
- 4.2 GHz - 1-core Turbo

Maximum clock speeds for the new Amber Lake chips suggest significant improvement in processor speeds over the 7th-generation Kaby Lake processors. For comparison's sake, Turbo Boost topped out at 3.0GHz on the 1.2GHz entry-level processor, 3.2GHz on the mid-level 1.3GHz processor, and 3.6GHz on the 1.4GHz high-end chip option in the previous-generation machines.

All of the chips use Intel's UHD 620 integrated graphics and are expected to be released in the third quarter of 2018, with the timing perfect for a fall refresh of the 12-inch MacBook.

Dell's upcoming and as-of-yet-unannounced XPS 13 2-in-1 machine confirms the existence of the Core i5-8200Y and Core i7-8500Y processors, both of which are listed as processor options for the new device.

Intel first announced its upcoming Amber Lake chips at Computex, but thus far has not provided official info on the upcoming processors.

Rumors have not indicated when updates to the 12-inch MacBook will be available, but Apple could introduce refreshed machines alongside new iPhones in September, hold an event in October, or release them on a random date as it did with the recent MacBook Pro.

The recent launch of the MacBook Pro also hints at one new feature we could potentially be seeing in new 12-inch MacBook models aside from processor upgrades -- a third-generation butterfly keyboard.

2015 and later 12-inch MacBook models have suffered from the same issues with keyboard failures, so it would make sense for Apple to include an updated keyboard in those machines as well, if, as speculated, the "quieter" third-generation MacBook Pro butterfly keyboard's new silicone coverings do indeed prevent dust from infiltrating the keys.

The lack of of TB3 on the MacBooks is bizarre. No TB no buy.
 
Shame it's still 14nm. That's what happens when you become big and complacent.

Right. Because there's no competition in the space at all so Intel is just sitting around. It's not at all related to the fact that shrinking the transistors is getting harder and harder the smaller we go.

What about Thunderbolt 3?

Wondering the same thing. I figure whenever TB3 is built into the processor without the need of a separate controller there's no reason not to change the port functionality. I know that's on the Intel roadmap somewhere, but is it here yet? Google results aren't encouraging.

Do people buy MBs? Isn't the 13" Pro nTB a better deal?

Form factor matters. (See below.)

I've always wondered what the purpose of the MacBook was. In theory, it fills a niche in between the keyboard-less larger screen iPad and the new standard 13" MacBook Pro.

...

It is simply a design failure. And it's not even a pretty or powerful design failure like the pro line.

Funny story. When I upgraded to a 15" Pro, my wife got my 13" Air and loved it. Sometime later I was checking out Craig's List since I grab deals from there now and again and I came across a pretty killer deal on a 2015 12" MacBook. I bought it because the price was good, despite having no specific need for it. When I brought it home I was expecting the usual line of questioning about "yet another computer." However, she looked at it, asked to see it, then slipped it in her purse. "I think I'll keep this." She's been using it since.

Form factor really matters to some people. The one port thing? The underwhelming performance? The keyboard? (Unlike me, she doesn't hammer her keys.) None of these things mattered at all. They really haven't mattered. For the purposes of a personal and professional machine (she's an attorney) it's been a great computer for her. Carrying just a purse instead of two bags to meet with clients was far more important than anything else.

To a lot of people, performance (and even price/performance ratios) aren't the be all end all of deciding on a machine. If a machine isn't slow to a point that annoys a user's threshold, they're good. With I/O being as fast as it is, even on these machines, for office work they're plenty fast. I think that point is missed on these forums a lot. Just because a computer doesn't suit your needs or your tastes doesn't mean it doesn't fill a niche.
 
Nah. I don’t think many people buying the 12” MacBook really care about TrueTone anyway. I don’t. What I’d like to see, maybe in this order too:
[...]
7. Quad-core
The first quad-core chip in the 45 W TDP class appeared in MBPs in 2011. The first quad-core chip in the 29 W TDP class appeared in 2018. It'll be a couple of years before it comes first to the 15 W TDP class, let alone the 4.5/5 W TDP class.

The processor upgrade looks good, intel have done a decent job. All Apple need to do is drop the price of the 12'' Macbook to the same as the current Air 13'', introduce a 14'' version at the same price as the current 12'' price and replace the headphone port with another USB-C.
Sounds good to me. I've often thought that if you look at what they've done with the MacBook, I like it but the 13" screen of my MBA is as small as I'm comfortable with and if anything a slightly larger screen would be preffereable. I don't want a larger laptop so the 15" MBP is out. But take the size of the MBA use the chassis form factor of the MB and give it a 14" screen (which is doable) and that would be perfect. I don't need extra ports so instant buy.
 
Apple will probably put these CPU and a Touch Bar in the MacBook. Jack the price up $400 and continue to sell the current model at the current price.
 
I really want to see a Mac pro update. Don't want one, but I want to see what Apple can do.
Yea, I'd love to see all the possibilities of Apple now.
I have to say that the quality difference between Mac and Windows has been much smaller this day.
Looking forward to the product's update this year, and probably, buy a new one.

1. Better trackpad
2. 2nd USB-C port
3. USB 3.1 Gen 2 10 Mbps
4. Thunderbolt 3
5. 720p iSight camera, with better low light ability
6. Better keyboard
7. Quad-core

My only point about True Tone really is i think it would be great for someone like me who writes a lot and uses their Mac throughout the day. I'm not sure if they will bring it to the 12" MacBook but it would be nice.
 
I’ve had a stock standard bottom of the range MacBook since rev1. I love it. It’s so light I use it everywhere.

It’s surprisingly snappy and I’ve even used it for a stint at work while I was between computers where it ran MS suite and InDesign without any problems.

The one port and the keyboard have never been a problem. I prefer the keyboard on my MacBook over my 15 2013 MacBook Pro. And definitely prefer the size and weight.

Right. Because there's no competition in the space at all so Intel is just sitting around. It's not at all related to the fact that shrinking the transistors is getting harder and harder the smaller we go.

Carrying a laptop bag from a venue to hotel when there is no cab or too close to justify the expense, waiting in line at TSA checkpoints, waiting to board, waiting to debark, standing in a "shuttle" (SFO), waiting to check-in at the hotel, waiting in the terminal when there isn't enough time to sit down, but just enough time to choke down a meal in the food court. Yes, the ounces and pounds add up, year after year, mile after mile.

Its called empathy, you might want to try it some time.
Yep, I've done all that over the course of way more than a million miles air travel. Had to do it with a variety of work-issued Windows laptops that have been, by and large, heavier than anything in Apple's current lineup.

Basically same thing happened in our household. It's a terrific computer for working professionals. Unless you're doing heavy computational stuff or video processing, it really fits the bill for almost everything.
 
I don't get it... who buys this laptop?
its the same price as the MacBook Pro, but less capable. The MBP is already light and thin enough. There is very little application for this kind of laptop in the real world.
 
Nah. Apple waited 2 months after m3-7Y32 launched last year. Remember, m3-7Y32 didn't launch until April 2017.

I wonder if they waited because the 2016 chips were missing HDCP 2.2. That didn't get added until 2017, across the Y line. Plus the 2016 m3-7Y30 was very slow. m3-7Y32 is considerably faster, and that's what Apple used.

In 2018, there is no reason to wait this year. All the chips are ready for release now, in terms of specs.
Thanks. I didn’t realize there was a mid-cycle update to the Kaby Lake Y chips. Do the Amber Lake chipsets support 10Gb/s USB 3.2?

Right now, the Amber Lake CPUs being discussed are based on Kaby Lake and do not look to be incorporating native USB 3.1 Type 2 into the chip die. I do not think anyone can say definitively yes or no at this exact moment, but based on Intel's rather obtuse support of USB 3 in general, I would put my money on No, they will not support USB 3.1 Type 2 when they are launched. I do hope to be pleasantly surprised though.

But what about when you need to go outdoors in the winter? Do you wear a short sleeve t and forego the wool coat?

What about a business meeting? Do you skip the tie and blazer and undershirt because they add a pound and a half?

Do I need to empathize with a person who suffers because he HAS to wear clothing by law since it adds an extra 4 or 5 or 6 lbs?

Are there documented health problems including emotional suffering from lack of empathy amongst those who carry 5 or 7 or 8 lbs laptops, not including the weight of the pack itself or peripherals?

Conversely, do we see a reduction in documented health problems now that very lightweight laptops are widely available?

For me, the weight of a half full water bottle (10-12 oz) is worth it on a hot day so I generally carry water with me most days. Can I file suit against camelbak for it's 90 oz bladders? That's at least an extra 6 lbs with the pack itself.

Some people are taking the concept of 'suffering' to absurd and bizarre new levels.
[doublepost=1531934459][/doublepost]This entire thread has devolved to arguments between people who think what matters to them is what should matter to everyone else, on the one hand, and the people who like the MacBook 12” on the other.

The MacBook and the MacBook Pro are different machines, and the funny thing about people is that they tend to like different things.

To me, picking up a MacBook is almost magical. It’s so light and balanced, other laptops, including the MBP. Would I use it for everything? Of course not!

But the great thing about computing today is that one does not need to do so.

Apple is a business. It has different products for different uses. The MacBook is the best for portability - for use on a plane tray table or lap, rather than in the overhead compartment, accessible for a quick note when I’ve gone to bed, but where an IPad’s kB isn’t enough, and so on -but those are just my uses for it. YMMV.

I suspect it won't even get 10 Gbps USB 3.1 Gen 2, much less 10 Gbps USB 3.2 Gen 1x2. We may still be stuck with 5 Gbps USB 3.1 Gen 1, esp. considering it seems the new Dell can use the 7th gen and 8th gen chips interchangeably. Presumably that means they're using the same existing chipset.
 
IceLake/TigerLake is going to do wonders for the MB (and all notebooks, actually). Until then, the MB probably won’t be able to meet my needs.

You are right, uh...mostly/partially...

Based on my cursory reading of the "7th Gen (U/Y) and 8th Gen (U Quad-Core) Intel® Processor Families I/O Datasheet, Vol. 1" on Intel's website, the Core Y-Series has a total of x14 PCIe 3.0 lanes, of which 4 are restricted to USB functions leaving a total of x10 lanes for the various I/O the CPU needs in order to function (SSD/Flash, Wi-Fi/Bluetooth, etc), although it lists a max of 6 PCIe port (devices) active. As such, there does not seem to be a need for the MacBook to use an external PCH (QM170/HM170) at all as the 13"/15" MacBook Pros do.

After looking at iFixit's teardown of the 2017 MacBook, no PCH is listed in the callouts of their photos, so I feel pretty confident in making that assertion. This sort of blows my mind as I expect there to be a PCH somewhere on the MacBook's PCB. However, the QM170 uses about 6w of power, so any little bit less drain to help the MacBook get better battery life helps.

In the Intel document, USB 3.0 is listed as supported and as USB 3.1 Gen 1 is essentially USB 3.0 with the Type-C connector, I think we can assume that until we are able to read the Datasheet that is presented when the Ark listing becomes available for the Amber Lake CPUs, we are only getting USB 3.1 Type 1 (5Gbps). Some of the rumored screenshots listing the CPU names - Core m3-8100Y, Core i5-8200Y and Core i7-8500Y - also suggest they are Kaby Lake and I have no reason to doubt that as Cannon Lake (10nm) is nowhere to be found.

Source - https://wccftech.com/intel-whiskey-lake-u-8th-gen-core-i7-8565u-core-i5-8265u-cpu-leak/

Long story, short - your suspicions are correct, we are not getting USB 3.1 Gen 2 in the next MacBook, unless a miracle occurs.

Or perhaps I'm wrong. I had actually seen this page before and noted the specs, but then I totally forgot about it:

https://pc.watch.impress.co.jp/docs/column/ubiq/1126720.html

It states that Amber Lake Y will likely use the PCH originally developed for Cannon Lake. It was supposed to be a 14 nm part to pair with the 10 nm Cannon Lake chips, but this page suggests they are keeping CNL-PCH on track, but pairing it with 14++ nm Amber Lake Y instead. So, while the auto-translation seems a bit rough, there is hope that the 2018 MacBook could get 10 Gbps USB 3.1 Gen 2.

Mind you I thought it might be more meaningful to me, but it turns out I haven't had any need for 10 Gbps. My 1 TB Samsung T5 USB-C SSD, which was a brand new release last year, is limited to 5 Mbps yet has proven to be fast enough for me.

I guess a more meaningful improvement would be Thunderbolt 3, but that won't be out until the ICL-PCH is available, earliest 2019 according to that page.

The 13" MBP's also don't have a separate PCH. The reason is that the lower end Intel mobile CPUs include a PCH in the CPU package. If you look at the teardown of the new 13", the CPU package contains three dies: The CoffeeLake CPU, the 128MB eDRAM cache, and a PCH.

Only the H-series mobile, desktop, and Xeon processors need an external PCH.

Intersting...had not seen that one at all. Well, hope springs eternal. Thunderbolt 3 should be the goal for the MacBook as the MacBook Air received Thunderbolt after roughly three iterations. However, given the limited battery and PCB space, USB 3.1 Gen 2 would at least help give the MacBook a little breathing room, especially for those who want to use a USB-C Dock and/or a 4K display@60Hz and full USB 3.0 speed as opposed to choosing between 4K@30/USB 2 or 4K@60/USB 3. Although being limited to 4K@60 (8-bit, 4:2:0) is acceptable, it is not ideal. Should be an interesting couple of months.

Gen 2 won't help this. 4K@60 is using the entire 4-lane DisplayPort 1.2 Alternate Mode, leaving available only the legacy USB2.

What could help is a 2-lane DisplayPort 1.3 mode that leaves the other two lanes available for USB3.

BTW, the maximum theoretical speed for 5 Gbps USB 3.1 Gen 1 is 625 MB/s. The Samsung T5 maxes out at about 555 MB/s in synthetic benchmarks, and in real world benchmarks can hit around 440 MB/s. Not too bad for USB. To put it another way, it's close to SATA III speeds, and SATA III is what many Windows laptops run for their main storage. So I'm not going to complain too much about Gen 1 USB 3.1.

What we really need to open things up on this little machine is Thunderbolt 3.

That would require the use of a Thunderbolt controller chip, I guess.

The reason why Apple haven't fitted so far?
a. A cost reduction measure
b. It doesn't fit on the (tiny) motherboard
c. Heat and power consumption considerations are an issue
d. Marketing considerations

Since a 2018 MacBook refresh is probably going to include consideration for a 3rd generation butterfly keyboard (for extra quiet operation) I'd like to think that the MacBook would adopt a Thunderbolt port at the same time if the MBA was put out to pasture at the same time as the 2018 refresh.

Well, I hate to disagree with you, but the DisplayPort Alt-Mode on the USB-C connector is supposed to support DisplayPort 1.4a, not 1.2- https://www.displayport.org/faq/#tab-displayport-1-4a-standard'

Will DisplayPort Alt Mode on the Type-C connector support DisplayPort 1.4a?
Yes. All of the features associated with DisplayPort 1.4a will be available for the DisplayPort Alt Mode.

According to this site - https://www.extron.com/product/videotools.aspx - 4K@60, 8-bit, 4:2:0 - would consume 8.91Gbps, so I assume that its possible over Type 2. Yes, we would be stuck at USB 2.0 for peripherals...hardly a satisfactory approach, although I saw the DisplayPort website say that USB-C over Alt-Mode supported 4K@60 AND USB 3.0 speeds. I swear. I will post the link when I find it.

At this point, two USB-C ports support Type 2(10Gbps) on a new 13" MacBook sure would be nice...I guess I can dream.

Thanks for the clarification there, that was very enlightening!

It does makes a bit more sense, and would explain why the 2016-2017 13" MacBook Pro half slower TB3 ports on the right hand side.

Which also begs the question, since the 8th-Gen 28w U-Series CPUs now have x16 instead of x12 PCIe lanes, does the new 2018 13" MacBook Pro now support full speed across all four (4) Thunderbolt 3 ports? I haven't seen anything to tell me they changed that. Has anyone reported it?
