Re: M4 MacBook Pro

Can someone please help me out with this? I'm torn between Mac mini and and MacBook Pro, specifically the CPU spec difference.

MBP: Apple M4 Max chip with 16‑core CPU, 40‑core GPU and 16‑core Neural Engine

Mac mini: Apple M4 Pro chip with 14‑core CPU, 20‑core GPU, 16-core Neural Engine

What kind of workload would make me regret not having bought MBP over Mac mini given the above. Thanks!

It seems they also update the base memory on MacBook Air: > MacBook Air: The World’s Most Popular Laptop Now Starts at 16GB > MacBook Air is the world’s most popular laptop, and with Apple Intelligence, it’s even better. Now, models with M2 and M3 double the starting memory to 16GB, while keeping the starting price at just $999 — a terrific value for the world’s best-selling laptop.

But no update to a M4 for the MacBook Air yet unfortunately. I would love to get an M4 MacBook Air with 32GB.

I believe the rumor is that the MacBook Air will get the update to M4 in early spring 2025, February/March timeline.

The keyboard touch button (top right) is objectively hideous and looks cheap. My current TouchBar may be useless but at least looks nice.

The M4 Max goes up to 128GB RAM, and "over half a terabyte per second of unified memory bandwidth" - LLM users rejoice.

The M3 Max was 400GBps, this is 540GBps. Truly an outstanding case for unified memory. DDR5 doesn't come anywhere near.

Apple is using LPDDR5 for M3. The bandwidth doesn't come from unified memory - it comes from using many channels. You could get the same bandwidth or more with normal DDR5 modules if you could use 8 or more channels, but in the PC space you don't usually see more than 2 or 4 channels (only common for servers).

Unrelated but unified memory is a strange buzzword being used by Apple. Their memory is no different than other computers. In fact, every computer without a discrete GPU uses a unified memory model these days!

At least in the recent past, a hindrance was that MacOS limited how much of that unified memory could be assigned as VRAM. Those who wanted to exceed the limits had to tinker with kernel settings.

I wonder if that has changed or is about to change as Apple pivots their devices to better serve AI workflows as well.

I'm pleased that the Pro's base memory starts at 16 GB, but surprised they top out at 32 GB: > ...the new MacBook Pro starts with 16GB of faster unified memory with support for up to 32GB, along with 120GB/s of memory bandwidth... I haven't been an Apple user since 2012 when I graduated from college and retired my first computer, a mid-2007 Core2 Duo Macbook Pro, which I'd upgraded with a 2.5" SSD and 6GB of RAM with…

On the standard M4 processor. If you move the M4 Pro it tops out at 48gb or moving to the M4 Max goes up to 128gb.

Weird that the M4 Pro in the Mac mini can go up to 64GB. Maybe a size limitation on the MBP motherboard or SOC package?
