> M5 Pro supports up to 64GB of unified memory with up to 307GB/s of memory bandwidth, while M5 Max supports up to 128GB of unified memory with up to 614GB/s of memory bandwidth.

This is the important statement. 614GB/s is quite decent, however a NVIDIA RTX 5090 already offers 1,792 GB/s (roughly 3x) of memory bandwidth, for comparison.

You're right a $3600 graphics card is worse than a $2600 laptop; but from my perspectives they're very different products. Not least of all because even at $3600 for a RTX 5090 you still have the whole rest of the computer left to purchase.

Max version with the 614GB/s is a $3599 laptop

The RTX 5090 only has 32gb of VRAM. So the tradeoff is NVIDIA is for blazing speed in a tiny memory pool, but Apple Silicon has a larger memory pool at moderate speed.

Or, there's the DGX Spark, which effectively neutralizes both of these trade-offs, and is the same price as the RTX 5090.

For reference, DGX Spark is at 273 GB/s

It's not 5090 performance though.

Nothing stops you from plugging in a 5090. Nvidia ships ARM64 GPU drivers.

So, what were we talking about even then in the thread?

You can buy two m5 pro base model for the same price as a single 5090...

That's a fun comparison, but can you run those 2 m5 pros in parallel to accomplish 2x the work? Otherwise, you just told me you can buy 2 toyota corollas for the price of 1 F-150 while trying to convince me you can haul your boat behind both corollas at the same time.

You can also buy a 64gb mini, save $1k and do more work than what you could do with a single 5090.

In Europe I can get a 128gb mac studio m4 max for 300 euros more than a 5090 (for which you still need to buy a power supply, motherboard, cpu , &c.)

But the inference on the mac studio m4 max will be slower than on the 5090, even though you can load larger models.

All I'm saying is that the comparison doesn't make sense. The 5090 is faster on a small subset of tasks if attached to a computer which ends up being 3x the price of a m5 machine that fit the same model or the same price as a machine that fits models 5x bigger

So you're saying that buying 2 Corollas for the cost of 1 Ferrari engine would be better? Even though the Ferrari engine is much more powerful, it's useless without the rest of the car.

I imagine the upcoming M5 Ultra will be competitive in this regard. The M3 Ultra already has 819GB/s and it's two generations behind.
