Now that you bring it up, the M3 ultra Mac Studio goes up to 512GB for about a $10k config with around 850 GB/s bandwidth, for those who "need" a near frontier large model. I think 4x the RAM is not quite worth more than doubling the price, especially if MoE support gets better, but it's interesting that you can get a Deepseek R1 quant running on prosumer hardware.
