Apple product won't be the cheapest but it is a full package (CPU, RAM, VRAM/GPU, fast-storage, etc).

If you look at the pricing of a full (x86) AI workstation you'd need around the nvidia GPU, you'd approach $10k easily (and be using a ton more wattage too).

But the 5090 they use there is now going low stock and selling for over $7500 in some places.
