With the M2 Pro and M2 Ultra-based Macs out of the way, it's time for Apple to treat us to the highly anticipated M3-based Macs. Back in May, we learned that the Cupertino tech giant is testing the alleged M3 Pro SoC-based MacBook. Now, thanks to Gurman, it appears that Apple is expanding testing of M3 Macs. And this time it could be a new Mac mini. Here are the details.

According to the latest report shared by Mark Gurman via his Power On newsletter, Apple has expanded testing of its M3-based Mac models with a base variant of the upcoming M3 Apple Silicon. The alleged M3 Mac is tested with 8 CPU cores and 18 GPU cores with 24GB of RAM. The chipset consists of four efficiency cores and four performance cores. Gurman further added that the device in question is running the latest version of MacOS Sonoma 14.1. Based on the configuration, this will most likely be the next Mac mini, codenamed "Mac 15.12."

It is believed that there are currently seven M3-based Macs in development. This includes a 13-inch MacBook Air, a 15-inch MacBook Air, a 13-inch MacBook Pro, a 14-inch MacBook Pro with M3 Pro SoC, a 16-inch MacBook Pro with M3 Max SoC, and the aforementioned M3 Mac mini .

The entry-level M3 chipset is similar to the entry-level M2 SoC. Although the M3 Pro chipset will probably offer noticeable generational upgrades compared to last year's M2 Pro chip. Compared to the M2 Pro's 10-core CPU and 16-core GPU, the M3 Pro can be equipped with 12 CPU cores and 18 GPU cores. It will also pack an additional 4GB of RAM. This will be achieved through a new 3nm manufacturing process that will reduce the distance between the transistors on the chip.
