Understanding possibly five Apple M3 Series processors
Apple announced the M3 series of chips on October 30, 2023, along with the new MacBook Pro and iMac. The M3 is based on the 3 nm process and contains 25 billion transistors, a 25% increase from the previous generation M2. It has 8 CPU cores (4 performance and 4 efficiency) and up to 10 GPU cores. Apple claims CPU improvements up to 35% and GPU improvements up to 65% compared to the M1.
Apple M3 Pro
The M3 Pro is a more powerful version of the M3, with six performance cores, six efficiency cores, 14 to 18 GPU cores, 16 Neural Engine cores, up to 36 GB unified RAM with 150 GB/s memory bandwidth, and 48% more transistors. It is used in the 14- and 16-inch MacBook Pro. Apple claims the CPU performance is 30 percent faster than the M1 Pro and the GPU is 40 percent faster than the M1 Pro.
Apple M3 Max
The M3 Max is a larger version of the M3 Pro, with ten or twelve performance cores, four efficiency cores, 30 to 40 GPU cores, 16 Neural Engine cores, up to 128 GB unified RAM with up to 400 GB/s memory bandwidth, and more than double the transistors. It is used in the 14- and 16-inch MacBook Pro. Apple claims the CPU performance is 80 percent faster than the M1 Max and the GPU is 50 percent faster than the M1 Max.
Apple M3 Ultra is currently unreleased
The M3 series uses the N3E architecture 3nm process. The N3E process is purported to have a 15% performance boost and a 30% power saving improvement over the N5P process in the M2.
Apple says the M3 Series is 30% faster than the M1 Series, and 15% faster than the M2 Series.
The M3 series is improved but probably not enough for most people to upgrade from a M2 equivalent. The M3 series is improved enough for many people to upgrade from an M1 equivalent but not all people will find value even in that upgrade. I have no interest in spending the money to upgrade my M2 Pro or M1 Ultra which both work great.
The brilliance of Apple silicon is the components of each one are the same. There are just more or less of them in each type.
Performance of the various M3 processors, just like their predecessors really will boil down to the base M3 processor performance.
The CPU/GPU core counts are a bit unexpected, in some cases fewer than M2 Series. Also notice the M3 Pro memory bandwidth is down to 150GB/s and M3 Max 10 CPU core, 30 GPU core is 300GB/s.
It does appear that Apple has re-balanced the M3 Pro and M3 Max with a larger performance gap between them. We’ll see when benchmarks become available, but it looks to me like the M3 Pro has more emphasis on power efficiency than performance improvement, which is probably a neutral thing. The M2 Pro already punches hard and power efficiency is always a good thing in a laptop, but in many ways the M3 Pro is definitely a sidegrade from the M2 Pro. In other words about the same overall performance.
The M3 Max is a different story though. We’ll see when benchmarks become available but I’m going to guess the M3 Max performs similarly to the M1 Ultra.
The ‘Extreme’ permutation has yet to become real, but is surmised to be the next logical step up, should that be possible.

|Video Encode Engines||1||1||2||4||8|
|ProRes Encode-Decode Engines||1||1||2||4||8|
Assuming a 2 year processor life cycle, before the end of 2025 the M3 Series should be history and fully replaced by the Apple M4 Processor Series in newly released products.

Buying an Apple M3 Series computer
Any Apple M3 Series computer will be an incredible experience compared to music and video production on Intel hardware. However it is highly recommended to get at least 16GB of memory (or more) and 512GB storage (or more) if you select an M3 Series system.
There are 9 basic form factors of Apple macOS systems with M3 Series processors expected, 5 laptops and 4 desktops.
