Is Apple testing 6 Mac M3 machines for release in October?

According to a recent report from Bloomberg, Apple has recently begun testing a new Mac machine with the code name 'Mac15,12', equipped with the M3 chip, potentially a new version of the Mac mini.

Reports from journalist Mark Gurman in the latest Power On newsletter. According to Gurman's sources, the M3-powered Mac in testing features an 8-core CPU along with 10 GPU and 24GB of RAM. The 8-core CPU comprises four efficiency cores and four high-performance cores.

The version currently undergoing Apple testing may be a base model but upgraded with 24GB of RAM instead of 8GB. Gurman says: 'With the specifications of the M3 chip in this particular Mac, I believe it could represent a next-generation Mac mini.'

According to reports, although the number of M3 chip cores is similar to M2, the M3 Pro chip seems to bring about some changes. The M3 Pro chip offers 12 CPU cores and 18 GPU cores, up from the M2 Pro's 10 CPU cores and 16 GPU cores.

In total, 6 Mac M3 machines have been spotted in the third-party developer log obtained by Bloomberg:

• 13-inch MacBook Air M3 (code name Mac 15,1 and J513/J613)
• 15-inch MacBook Air M3 (code name Mac 15,2 and J515/J615)
• 13-inch MacBook Pro M3 (code name Mac 15,3 and J504)
• iMac M3 (code name Mac 15,4, Mac 15,5, J433, and J434)
• 14-inch and 16-inch MacBook Pro M3 Pro and M3 Max (code name Mac 15,7, Mac 15,8, J514, and J516)
• Possibly Mac mini M3 (code name Mac 15,12)

The M3 chip is expected to be manufactured using a new 3nm fabrication process, helping to reduce the distance between semiconductor balls on the chip. This will aid in improving performance as well as energy consumption. Let's wait and see!
