2 TB of NVME storage is little more than $200 off-the-shelf. 64 gigs of DDR4, high-bandwidth laptop memory costs ~$250. Even assuming Apple is springing for high-quality, high-speed RAM, $800 borders on insanity when other laptops offer similar configuration options at less than half the price. Apple's price gouging in this department is well-documented, I don't think I need to argue with HN users about that.

$250 will get you 64 GB of laptop memory but that will be operating at something like 1/8 to 1/16th the bandwidth. Similarly you can get 2 TB of NVMe for $200 but you need to go to the ~$350 range to approach the bandwidth, I haven't looked into IOPS.

I still think the prices are inflated over raw hardware but not as exaggerated as finding the cheapest parts with the same capacities would make it seem.

I just checked out some random Dell Precision laptop. They want $800 for 64GB RAM and $720 for SSD. Seems pretty comparable to me. Samsung 970 Pro 1TB is $270 on newegg, so it makes $540 for 2TB. Cheaper, but it's only PCI-E 3.
