There's some mention of Apple silicon here but it's worth expanding upon. Macs have a unified memory architecture. So if you have a Mac with 64GB of memory then the GPU can use all of that. This is potentially quite useful but Apple silicon in general is limited by memory bandwidth. For comparison, a 5090 is 1792GB/s. Here are some examples:

- GMKTek EVO-X2: 120GB/s reads, 212GB/s writes

- NVidia DGX Spark 273GB/s

- Mac Mini M4 120GB/s but only $600+

- Mac Mini w/ M4 Pro 273GB/s ($2199 for 64GB)

- Mac Studio M4 Max 410GB/s ($3500 for 128GB)

- Mac Studio M3 Ultra 819GB/s ($5500 for 96GB)

- Macbook Pro 16" with M5 Pro 64GB 307GB/s ($3300)

- Macbook Pro 16" with M5 Max 128GB 460GB/s ($5399)

Sadly, Apple discontinued the 512GB Mac Studio. Mac Studios are a little long in the tooth now and due for an upgrade this year. I suspect that prices will be a lot higher given the RAM prices but we'll see.
