It's official. Apple will hold a "Scary Fast" event on the evening of October 30, and all signs point to the arrival of the new 3-nanometer M3 chip, along with a wave of new Macs with the latest Apple silicon.

The new iMac M3 and possibly new 14- and 16-inch MacBook Pro M3 models are on the horizon. But how fast will these chips be?

As reported by Bloomberg, the top-of-the-line version of the M3 Pro chip has 12 CPU cores, 18 graphics cores, and 36 GB of memory; the current M2 Pro in the 14-inch MacBook Pro has up to 10 CPU cores, 16 graphics cores, and 32GB of memory. In other words, depending on the configuration, this is a fairly significant performance increase.

It is also worth noting that the M3 chip will likely be available in Max and Ultra versions, just like the M2 chip. At this level, M3 Max chips with 16 CPU cores and 32 or 40 GPU cores, as opposed to 12 CPU cores and 30 or 38 GPU cores, are likely to be available.

The M3 Ultra chip will take performance to the next level with a whopping 32 CPU cores and 64 or 80 GPU cores; the M2 Ultra already had 24 CPU cores and 60 or 76 GPU cores.

The M3 chip is not just about speed. Apple's 3nm chips could be up to 35% more power efficient than 5nm chips because they can pack more transistors into the same space.

Apple made the jump to 3nm this year when transitioning from the iPhone 14 Pro to the iPhone 15 Pro, and its manufacturing partner TSMC claimed that it could realize power efficiency gains of up to 35%. if similar efficiency gains are realized when moving to M3, the M3-powered MacBooks could achieve phenomenal battery life.

The MacBook Pro 14-inch with M2 Pro lasted a whopping 12 hours and 2 minutes, while the MacBook Pro 16-inch model with the M2 Max chip lasted nearly 19 hours.Benchmarks for the M3 chip series have not yet been leaked, but the new Mac to be the first to test the new MacBook Pro and show you how fast it is.
