A new Mac mini with M6 and M5 Pro was unveiled this week, but we’ve since learned three things about the product that weren’t highlighted by Apple.

#1: Memory bandwidth varies among configurations

If you’re planning to order a Mac mini, the pre-order page doesn’t tell the full story about a key spec: memory bandwidth. Digging into the technical specs reveals that your RAM choice might directly impact overall memory bandwidth.

The base M6 Mac mini with 16GB of RAM offers 153GB/s memory bandwidth. But if you upgrade to 24GB or 32GB of RAM, that number bumps up to 170GB/s.

Meanwhile, you’ll need to choose M5 Pro to get the maximum memory bandwidth of 307GB/s.
