Raspberry Pi 5 – 16GB RAM

The post was an Adafruit product page for the 16GB Raspberry Pi 5, listed at a price that makes the board look absurd next to a used ThinkPad, an N100 mini PC, or even an entry Mac. That sticker shock dominated the reaction, but the sharper point was that this is mostly a memory story. Several commenters pointed out that the 16GB model is basically an unusually expensive LPDDR4X package with a Pi attached, and that older memory types used in boards like this have been hit hard as manufacturing capacity shifts toward newer memory demanded by AI systems. A few also noted that Adafruit is on the high side, with other authorized sellers and Micro Center listing lower prices, though still nowhere near the old Pi narrative.

Do not treat the headline price as "the price of Raspberry Pi" in planning or purchasing. For product and ops decisions, split the market into three buckets: cheap Pi or microcontroller for embedded work, mini PC or used x86 for general compute, and expensive high-RAM Pi only when you need its software stack, GPIO ecosystem, or long-term embedded availability.

Discussion mood

Mostly negative on the headline price, with a lot of disbelief that a Raspberry Pi can now cost as much as a full mini PC or cheap laptop. Underneath that, the mood was more pragmatic than outraged: people mostly see this as a RAM-market distortion and a reminder that the high-memory Pi is a niche industrial or embedded part, not the default board hobbyists should be buying.

Key insights

  1. 01

    Industrial buyers now carry the platform

    Industrial and embedded demand explains why Raspberry Pi keeps selling even as hobbyists complain about price. The useful distinction is that businesses are paying for upstream software support, predictable Linux behavior, long availability windows, and an ecosystem they can ship around, not for the cheapest possible board.

    If you are evaluating Pi as a product component, compare it against the engineering cost of weaker board support packages and shorter lifecycles, not against eBay desktops. If you are only buying for hobby or homelab use, stop assuming the industrial buyer's priorities should set your hardware choice.

    Most hobby projects should move downmarket

    The better replacement for an overpriced Pi 5 is often not a mini PC but a much smaller board. Pi Zero 2 W, Pico 2, and ESP32-class devices cover a surprising share of one-off builds, and commenters gave concrete examples from streaming clients to audio control to Meshtastic terminals. The old habit of reaching for a full Linux SBC first now looks lazy more than necessary.

    For new internal tools or prototypes, start by asking whether the job actually needs Linux, persistent multitasking, and that much RAM. If not, switching to a microcontroller can cut bill of materials, power, boot time, and storage-failure headaches immediately.

    The moat is software around GPIO

    GPIO alone is not special hardware anymore. USB adapters and rival boards can expose I2C, SPI, UART, and general-purpose input output just fine. What keeps Raspberry Pi sticky is the pile of libraries, tutorials, board assumptions, HAT compatibility, and known-good Linux setups that make peripherals work without burning developer time.

    When comparing alternatives, price the migration cost of drivers, examples, and ops familiarity, not just the board. If your team depends on well-trodden sensor and peripheral workflows, a Pi can still be cheaper overall even when the sticker price looks irrational.

    PoE makes Pi attractive for home infrastructure

    Power over Ethernet is a practical edge that does not show up in raw performance comparisons. A stack of Pis with PoE HATs can run core network services from a single battery-backed switch, stay fanless, and mount cleanly in a compact rack. That is a different use case from “cheap desktop computer,” and mini PCs do not slot into it as neatly.

    If you run edge or home infrastructure where centralized power and silent operation matter, include PoE design simplicity in your comparison. Hardware that looks worse on compute per dollar can still win on deployment ergonomics and resilience.

    Headline pricing is distorted by memory, not compute

    The wild number comes from the memory package, especially for 16GB LPDDR4X in this form factor, not from Raspberry Pi suddenly extracting giant margins on the board itself. That reframes the product as a special-case SKU kept alive for people who truly need it, rather than proof that the entire Pi line now costs hundreds of dollars.

    Do not let an expensive top-end memory configuration anchor your view of a product family. In procurement and messaging, separate RAM-driven outliers from the base platform or you will make the wrong build-versus-buy call.

Against the grain

  1. 01

    Cheap fallback boards are not always available

    The advice to buy a Pi Zero 2 W instead breaks down if you cannot actually source one. Commenters in Germany and elsewhere said stock is poor and prices have risen sharply, which means the neat market segmentation of “use a cheaper Pi” is sometimes more theory than reality.

    Before standardizing on the low-end Pi as your cost escape hatch, validate channel availability in your region. A design that only works at list price from one official page is not a real supply plan.

    Raspberry Pi is not uniquely strong on Linux support

    One commenter pushed back on the idea that Raspberry Pi leads all serious alternatives on kernel quality. NXP i.MX was called out as stronger on mainline Linux support than Broadcom-based Pi platforms, which weakens the claim that Pi is the only safe choice for maintainable embedded Linux.

    If mainline kernel quality is the deciding factor for a commercial design, benchmark Pi against NXP and similar vendors instead of assuming all non-Pi options mean bad software support. The right comparison set is narrower than “Pi versus random Chinese SBCs.”},{
