Apple is currently testing four new M4-powered Mac models, according to Bloomberg‘s Mark Gurman. Apple is said to be planning to release refreshed MacBook Pro, Mac mini, and iMac models with M4 chips this year, and we could see the first of the new models as soon as October.
Developer logs reveal that the four machines are powered by base-level M4 chips. Three of the Macs boast a 10-core CPU and 10-core GPU. The fourth machine reportedly is equipped with an 8-core CPU and an 8-core GPU, which is not an M4 configuration that has been used so far. All four of the M4 Macs will boast 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 chip in the high-end 1TB and 2TB models is the same one that will be used in some of the Mac models.
Gurman makes no mention of 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. Mentions of those higher-end chips were not found in the developer logs.
