Samsung Unveils Industry's First 32Gbit DDR5 Memory Die (anandtech.com) 17
Samsung today revealed the world's first 32 Gb DDR5 DRAM die. From a report: The new memory die is made on the company's 12 nm-class DRAM fabrication process and not only offers increased density, but also lowers power consumption. The chip will allow Samsung to build record 1 TB RDIMMs for servers as well as lower costs of high-capacity memory modules. "With our 12nm-class 32 Gb DRAM, we have secured a solution that will enable DRAM modules of up to 1 TB, allowing us to be ideally positioned to serve the growing need for high-capacity DRAM in the era of AI (Artificial Intelligence) and big data," said SangJoon Hwang, executive vice president of DRAM product & technology at Samsung Electronics.
32 Gb memory dies not only enable Samsung to build a regular, single-rank 32 GB module for client PCs using only eight single-die memory chips, but they also allow for higher capacity DIMMs that were not previously possible. We are talking about 1 TB memory modules using 40 8-Hi 3DS memory stacks based on eight 32 Gb memory devices. Such modules may sound overkill, but for artificial intelligence (AI), Big Data, and database servers, more DRAM capacity can easily be put to good use. Eventually, 1TB RDIMMs would allow for up to 12 TB of memory in a single socket server (e.g. AMD's EPYC 9004 platform), something that cannot be done now.

This is 2^16 *times* that amount! (in 8-bit word, non-parity). Move to 64-bit ECC, we're looking at around 2^24 times the number of bits.
My Ghod - it's full of bits!

At the very minimum in server applications you are going to want at least 8 channels which means 8 TB of ram. Probably overkill for many. Access to that 8 TB would be 3 times slower than present day high end consumer GPUs.
For AI applications especially there needs to be a reasonable ratio of capacity to the time required for the controller to scan the chip. 1TB is as far as you can possibly get from that. Unless you are batching a lot of concurrent operations from the processors cache the CPU is just jus

This will hopefully improve Apple's profit margins. The market already agrees to Apple's RAM tax and artificial supply scarcity.

Don't exaggerate, it's only a leg. The ARM is for the CPU.
