Apple has ramped up testing of four new Mac models equipped with an M4 chip, according to Bloomberg's Mark Gurman. Apple is planning to refresh the MacBook Pro, Mac mini, and iMac with M4 chips this year, and we could see the new models sometime in October.

The four machines have base-level M4 chips, according to developer logs. Three of the Macs have a 10-core CPU and 10-core GPU. The fourth machine has an 8-core CPU and an 8-core GPU, which is not an M4 configuration that we've seen so far. All four of the M4 Macs have either 16GB or 32GB of Unified Memory.

The M4 used in the 256GB and 512GB iPad Pro models has a 9-core CPU and 10-core GPU, while the chip used in the 1TB and 2TB models has a 10-core CPU and 10-core GPU. The high-end iPad chip is the same chip that will be in some of the Mac models.

Gurman does not mention M4 Pro or M4 Max chips, which would be used in higher-end Mac mini and 14-inch MacBook Pro models, as well as the 16-inch MacBook Pro. M4 Pro and M4 Max chips would have a higher number of CPU and GPU cores, as well as more maximum memory.

It is not clear if Apple is only introducing lower-end models with the standard M4 chip, or if there are plans for M4, M4 Pro, and M4 Max models but those higher-end chips simply weren't seen in the developer logs.

Prior rumors have suggested that both the 14-inch and 16-inch MacBook Pro models would see a refresh, and Gurman previously said that the new, slimmer Mac mini that's in the works will be available with both M4 and M4 Pro chip options.

All four of the M4 Macs have either 16GB or 32GB of Unified Memory.
16 GB of RAM to start across multiple Apple product lines?!?!? 😮🤯

Timmy must have gotten replaced by an alternate universe doppelgänger... this news is the clearest evidence I've seen for the existence of a multiverse... 🤔

(joking aside, I'm glad Apple is finally moving up the base RAM for the first time in over a decade)
 
Wait wait wait, does this report say that it's not just moving the base from 8GB to 12GB as speculated, but the entry level is now 16GB? That's great news if that's what it's saying! Hope there aren't 8GB entry-er models hiding out there


8 core M4 instead of the already binned iPad Pro's 9 core is slightly odd, but it's 4+4 instead of 3+6 so probably makes sense from an available power and thermal situation
 
No Pro chips? Huh. I wonder what they’re cooking up
This is just based on developer logs so it could just mean the chips are being tested separately or will be tested in the coming weeks.

Considering the base M4 is within spitting distance of the M3 Pro in terms of multicore performance I would think Apple would want to update all three models in short order now that the 14" MBP has a base chip version.
