What’s Actually Happening? The AI Tax
So let’s not beat about the bush, AI is the big driver behind this, and with that comes the AI Tax. But what exactly is it? Well, stripping off the marketing buzzwords, it’s a supply and demand crisis, but one that’s been artificially accelerated by a massive shift in industry priorities.
To understand why your 32GB kit of DDR5 is suddenly a lot more expensive, you have to look at what the big players like OpenAI, Google, and Microsoft are buying. Training these massive AI models requires an obscene amount of computational power, and crucially, an immense amount of ultra-fast memory. This is where High Bandwidth Memory, or HBM, comes in. HBM is the premium thing that powers the AI data centres, and right now, the companies building these centres can’t get enough of it.
The problem for us is that HBM, standard DDR5, and the NAND flash used in your SSDs are all made by the same three companies: Samsung, SK Hynix, and Micron. These manufacturers have a specific amount of production capacity and they can’t just click their fingers and build a new fabrication plant overnight. Instead, those facilities take years and billions of dollars to construct.
So, faced with limited capacity, they have to make a choice. Do they produce standard DDR5 memory for gamers, where the profit margins are razor-thin, or do they retool their production lines to make HBM for enterprise AI customers who are willing to pay almost any price to get their hands on stock?
The answer is pretty obvious; they’re chasing the money, and with that we’re seeing a massive reallocation of manufacturing capability. The silicon wafers that would have historically become your next affordable SSD or RAM kit are now instead being used to create HBM3e for Nvidia’s latest AI superchips. SK Hynix and Samsung have effectively diverted their resources to feed the AI boom, leaving the consumer market with a shrinking supply.
To make matters worse, this isn’t an accident. After the memory market crashed in 2023 and prices hit rock bottom, these manufacturers lost billions. Now, they’re quite happy to let supply tighten and prices rise to claw back those losses. They aren’t just prioritising AI; they’re actively managing production to ensure the days of dirt-cheap memory don’t come back anytime soon. That is what the AI Tax is. We are effectively subsidising the data centre gold rush with higher prices on our gaming PCs, and now DDR5 is back to the prices it started at when it launched, and will continue to rise beyond that.
