At 4 bit quant (requires 64GB) the price of Mac (4.2K) is almost exactly the same as 2x5090 (provided we will see them in stock). But 2x5090 have 6x memory band

At 4 bit quant (requires 64GB) the price of Mac (4.2K) is almost exactly the same as 2x5090 (provided we will see them in stock). But 2x5090 have 6x memory bandwidth and probably close to 50x matmul compute at int4.

    You can also buy cheaper second hand apple silicon macs with plenty of RAM. I only buy second hand m1 macs for what is worth.
