Looking at forum posts discussing deals on RAM kits, we can see that good deals on 4 GB RAM kits cost about $100 at the time. Well, whether we look to 32 GB or 16 GB kits, at the time of writing the price per GB for reasonably-specced DDR5 is about the same for both: $15–16 per GB. A decent 32 GB (2x 16 GB) DDR5 kit, for instance, goes for about $500 right now. These days, the equivalent would be 16 GB or 32 GB, with a weighting toward the latter. Even if these numbers aren't completely accurate, they're so far from today's RAM prices that the gulf between the two certainly holds.
