| > 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. |

| 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. |

| > NVIDIA RTX 5090 already offers 1,792 GB/s You can buy two m5 pro base model for the same price as a single 5090... |

| ▲ | dylan604 6 hours ago | parent [-] | | 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. | | |
| ▲ | lm28469 6 hours ago | parent [-] | | 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.) | | |
| ▲ | hrmtst93837 6 hours ago | parent [-] | | But the inference on the mac studio m4 max will be slower than on the 5090, even though you can load larger models. | | |
| ▲ | lm28469 6 hours ago | parent [-] | | 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 | | |
| ▲ | dylan604 6 hours ago | parent [-] | | 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. |
