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.

It is interesting to see the improvements. These are only like what 4.5w? It would be cool to someday see a 4 core chip at this ultra low voltage. I had a 2015 MacBook and most of the time I didn’t notice the slowness unless I was doing something with Xcode.

Wow I hadn’t even clocked that there was another 14nm Y - I thought 8th gen Y was still set to be cannonlake.

Do people buy MBs? Isn't the 13" Pro nTB a better deal?
Yep people buy them, I bought one to always take with me. The 13” Pro is too big an heavy for me. Maybe the 13” Pro is a better deal if you look at the specs like speed, but for what I need to do on the road speed isn’t the most important factor, the size and weight is. :)

Interesting, an article on leaked processor details.
Certain members of this forum won’t be happy if their views on the 8-core i9 are anything to go by.

In all seriousness, they look good and I would imagine we will see an extra 100MHz above those stock clock speeds as Apple has done in the past.

Waiting for Apple to put A12 into this... A11 is already more powerful than these chips 8(

I suspect that if marzipan is on track, next year (more likely early 2020) we’ll see an A chip in these computers
[doublepost=1531854963][/doublepost]Does anyone know if a dual core chip could go in the MB or would it end up frying it?

Looks like i ll be waiting for 2019... Hope by then Apple can catch up with smaller bezels, add at least 2 more USB-C ports (1 thunderbolt) and higher density/resolution on the screens at 12".

2017 MacBook still kicking ass. Might just use the money for a new iPad
