The next iMac could crush Intel with a monster 20-core duo chip

Apple’s iMac Pro was dubbed its most powerful Mac ever in 2017, but the all-in-one was discontinued earlier this year without ever living up to the hype. Now, it could be on the cusp of an explosive return with one of the beefiest chips ever to grace an Apple machine.

According to YouTuber Max Tech, Apple will likely equip the upcoming high-end iMac with a brand-new chip that essentially fuses two M1 Max chips together. This Frankenstein creation will apparently be named the M1 Max Duo and provide Mac users with one of the most powerful devices they’ve ever laid their hands on, featuring a 20-core CPU, a 64-core GPU, and up to 128GB of memory.

Where does Max Tech get this info? Most of it seems to come from a wide range of sleuthing and digging. For instance, they cite as evidence an article from reliable reporter Mark Gurman, who stated Apple is working on a new chip with up to 16 high-performance cores and four high-efficiency cores. That 20-core chip would feature twice as many CPU cores as the current 10-core M1 Max, suggesting Apple might combine the powers of two M1 Max units like some sort of Wonder Twins cut content.

The current Intel-based 27-inch iMac offers a 10-core Intel i9 CPU that still outperforms the M1 Max in some cases. If Apple were to outfit the new top-end iMac with that M1 Max, users would be disappointed in the apparent drop in performance, Max Tech reasons. If you follow that logic, Apple must be working on something better for its most performant desktop all-in-one.

As well as that, developer Hector Martin has claimed that macOS drivers contain numerous multi-die references (perhaps alluding to a combo chip like the mysterious M1 Max Duo), and that the current M1 Pro and M1 Max chips are engineered in such a way as to make a duo chip feasible.

The problem is that all this M1 Max Duo speculation is exactly that: Speculation. Until we see the new iMacs in the flesh — which could happen as soon as spring 2022 — it’s best to take all this news with a pinch of salt.

What else can we expect to see from the new iMac? A number of outlets and sources, including Max Tech and display industry analyst Ross Young, have claimed the iMac Pro will feature a 27-inch display that packs in mini-LED tech and a variable ProMotion refresh rate of up to 120Hz. We also expect a similar slim-bezel design as the 24-inch iMac, although perhaps in more muted colors, and a touch ID-equipped Magic Keyboard.

Apple’s MacBook lineup is full of great laptops, but the 13-inch MacBook Pro really doesn’t feel like it belongs. Yet a new report claims Apple will update that device with an M3 chip later this year instead of simply killing it off.

The news comes from 9to5Mac, and the website says its sources have confirmed the 13-inch MacBook Pro is going to get a refresh with a new M3 chip, potentially at Apple’s Worldwide Developers Conference (WWDC) in June.

The M1 iMac made a big splash when it launched in spring 2021, but it’s been a long two years without updates since then. There’s some good news for Apple fans, though, as a new iMac is apparently almost upon us.

That’s according to a new report from Bloomberg journalist Mark Gurman, who claims the next iMac is undergoing production tests as we speak. This stage of development (known as engineering validation testing, or EVT) means the product is getting close to launching.

Apple just made a huge move to power up your next MacBook

Your next iPhone or Mac could have a major advantage over rival devices, with performance and efficiency that nothing else can match, if a new report is to be believed. It claims Apple has gobbled up the entire supply of a new breed of superefficient chips.

Those chips are manufactured by a company called TSMC that has made Apple’s powerful mobile and computer chips for years. If correct, the report from DigiTimes (via MacRumors) implies Apple’s competitors -- whether they’re making Windows PCs or Android smartphones -- will have to wait their turn while Apple has its fun with the brand-new 3-nanometer chips.
