Every Steam Deck has 16GB LPDDR5-6400. I’ll use regular DDR5-6400 as a stand-in. In 2 years, that’s gone from $100 to $300. So, +$200 in memory costs.

The cheapest 1TB M.2-2230 has gone from $70 to $170. So +$100 for the highest-tier OLED. (512GB M.2s are harder to find history on… but they also seem to have gone up about $100.)

So, the RAM & Storage in a Steam Deck now cost another $300. (Yes, I realize the components are probably cheaper for Valve. But it just puts the prices into perspective.)
