CPU-Z Utility Details Big Decline In PCs With 64GB Or Even 32GB Of RAM

When I splurged on a 128GB DDR4 memory upgrade for my main PC, I knew at the time that it was overkill and a needless expense. However, that was before the current AI craze stripped the consumer market of reasonably affordable, higher capacity memory kits. In hindsight, I'm glad I spent the money, even if it means having to be on the lookout for Sam Altman coming for my PC (not really, folks). I bring this up because some fresh CPU-Z data suggests something unusual is happening, with higher-capacity memory configurations losing ground while more modest setups gain traction.

By unusual, I mean the data bucks the trend of what would be normal if we were in normal times. We are not, of course, and so the trend is not unexpected, even if a little depressing.

The figures come from CPU-Z's online Validator database, which tracks hardware configurations submitted by users. Developer Samuel Demeulemeester, better known as Doc TB on X, noted that both 32GB and 64GB systems have registered year-over-year declines for the first time.

Fresh stats from CPU-Z! 🔎 For the first time ever, RAM capacity on PCs has declined year-over-year : -2.5% for 32 GB and -18% for 64 GB! https://t.co/ya0soA55bR

According to the latest CPU-Z numbers, 32GB remains the most popular memory capacity, accounting for 37.2% of validations. However, its share has fallen 2.5% year-over-year. That's not a massive dip, but the downward trend is more pronounced at 64GB, which declined 18% year-over-year to a 7.3% share.

Meanwhile, setups with 16GB of PC memory are gaining ground, rising 12.9% to account for 33% of submissions. That puts 16GB within striking distance of 32GB, a notable development considering how enthusiast builds have increasingly gravitated toward larger memory capacities.

The trend extends beyond those popular capacities. Systems with 48GB of RAM fell 22.5% to a 1.7% share, while 96GB and 128GB setups declined 26.5% and 28.7%, respectively.

Is the memory shortage to blame for the downward adjustment in memory capacity? It's certainly feasible, given how expensive memory has become in the wake of manufacturers prioritizing chip supplies to more lucrative data center customers.

It's not an easy thing to assess, however, as there are other happenings that deserve consideration. For one, there has been a concerted effort on the software side to make platforms run more smoothly on fewer resources. Case in point, Microsoft recently made Windows 11 up to 40% faster on PCs with just 8GB of RAM, a capacity that is gaining traction again.

There's another interesting detail hiding in the numbers. While most larger configurations are losing ground, 24GB systems have increased their share by 19.7%, reaching 2.3% of validations.

That's still a relatively small slice, but it raises an interesting possibility. With 24GB DDR5 modules now available, some PC buyers could be choosing capacities between the traditional 16GB and 32GB options rather than paying extra for memory they might not fully utilize.

Interestingly, 48GB isn't enjoying the same momentum as a potential alternative to 64GB. Its declining share suggests the shift isn't simply a matter of buyers stepping down one memory tier.

Another thing worth considering is how DDR4 is making a comeback while the market figures itself out. The latest figures show DDR4 accounting for 54.5% of CPU-Z submissions, up 6% year-over-year, while DDR5 slipped 2.9% to 32.9%.

One important caveat is that CPU-Z's figures represent voluntarily submitted hardware validations, not total PC sales. Similar to Valve's monthly Steam hardware and software surveys, CPU-Z's data is not representative of every PC in use. At least part of the shifts could reflect who's submitting results rather than a broader decline in installed memory.

Still, Occam's razor comes into play here, and it says that memory pricing is likely the main driving force.
