Why Raspberry Pi 4 Is Going 3GB: The LPDDR4 Price Shock Behind the Upgrade

If you are wondering why Raspberry Pi 4 is going 3GB, the short answer is simple: LPDDR4 memory prices have exploded. Raspberry Pi says the LPDDR4 DRAM used in Raspberry Pi 4 and Raspberry Pi 5 has risen seven-fold over the last year, and that price shock is forcing both price increases and a new 3 GB option. In other words, this is not a random spec tweak. It is a direct response to memory costs.

That also explains why Raspberry Pi says this move expands your options. Instead of pushing everyone toward a more expensive 4GB board, the company is adding a 3GB Raspberry Pi 4 so you can buy closer to what your project actually needs.

What changed with the new 3GB Raspberry Pi 4?

Raspberry Pi has introduced a new Raspberry Pi 4 3GB model at $83.75. The board is available through approved resellers, and the idea is pretty practical: give buyers a middle step between lower-memory versions and the now pricier Raspberry Pi 4 4GB.

That matters because a lot of Pi projects do not need a huge amount of RAM. If you are building a retro gaming box, a simple server, a smart home hub, a kiosk, or a light desktop, 3GB may be enough. You still get the familiar Raspberry Pi 4 Model B platform, but without paying for memory headroom you may never use.

Why Raspberry Pi prices are going up

Raspberry Pi says the main cause is the price of LPDDR4 DRAM, the memory used on Raspberry Pi 4 and 5 boards. According to the company, that memory has gone up by 7x in the last year.

The company says it has to pass on part of those costs. At the same time, it is doing engineering work to offer more memory-density choices so customers can "right-size" their purchase.

This is the key point: the 3GB model is not just another SKU. It is a pricing strategy built around expensive memory.

Which Raspberry Pi products are affected?

The biggest hits are on models with 4GB or more of memory. Raspberry Pi says these products are affected:

  • Raspberry Pi 4 and 5 variants with 4GB or more
  • Raspberry Pi 500 and 500+
  • All Compute Module 4, Compute Module 4S, and Compute Module 5 variants
  • Development Kit for Compute Module 5
  • Raspberry Pi AI HAT+ 2

Here are the announced increases:

Raspberry Pi 4 and Raspberry Pi 5

  • 4GB: +$25
  • 8GB: +$50
  • Raspberry Pi 5 16GB: +$100

Raspberry Pi 500

  • Unit only and kit: +$50

Raspberry Pi 500+

  • Unit only: +$150
  • Kit: +$150

Compute Module 4 and 4S

  • 1GB: +$11.25
  • 2GB: +$12.50
  • 4GB: +$25
  • 8GB: +$50

Compute Module 5

  • 16GB: +$100

Other products

  • Development Kit for Compute Module 5: +$25
  • Raspberry Pi AI HAT+ 2: +$50

If you were already looking at a Raspberry Pi 4 8GB or a high-memory Pi 5 for heavier workloads, this is where the pain shows up fastest.

Why 3GB makes sense right now

A 3GB board looks odd at first. Most buyers are used to 2GB, 4GB, or 8GB tiers. But from a pricing view, 3GB is actually a smart move.

Raspberry Pi is basically saying: if memory is the expensive part, why make you pay for more of it than you need?

That approach helps in a few common cases:

  • Home server: Pi-hole, Home Assistant, basic file serving, light Docker use
  • Media box: local playback, signage, streaming front-end
  • Learning and coding: Python, GPIO work, Linux basics
  • Portable setups: light lab kit, field testing, Raspberry Pi travel uses
  • Maker builds: sensors, dashboards, kiosks, small robots

For these jobs, 3GB can be a nice middle ground. You save money versus a 4GB model while keeping more breathing room than a 2GB board.

Raspberry Pi's "right-size your memory" message

This is the real theme behind the announcement. Raspberry Pi is telling customers to buy memory for their actual workload, not for vague future plans.

The company also pointed out a few prices it has managed to hold:

  • Raspberry Pi 400 with 4GB: $60
  • 1GB and 2GB variants of Raspberry Pi 4 and Raspberry Pi 5: between $35 and $65

That says a lot. If your project does not need extra RAM, there is no reason to jump straight to higher-memory models now that memory costs are inflated.

I think that is fair advice. A lot of people buy the biggest board they can afford, then use it for one browser tab, one script, or one service. For many builds, that extra RAM just sits there.

What about classic Raspberry Pi boards?

Raspberry Pi says it does not expect price rises for older classic products that use LPDDR2 DRAM. That includes:

  • Raspberry Pi Zero
  • Raspberry Pi Zero W
  • Raspberry Pi Zero 2 W
  • Raspberry Pi 1
  • Raspberry Pi 3
  • Raspberry Pi 3B+
  • Raspberry Pi 3A+
  • Compute Module 1
  • Compute Module 3+

The reason is simple. Raspberry Pi says it still holds substantial inventory of the older LPDDR2 memory used in those products. That cushions them from the LPDDR4 shock hitting newer boards.

So if your project is lightweight, an older Pi may still be a smart buy in 2026.

Is this bad news for Raspberry Pi 5 buyers?

A little, yes. The same LPDDR4 pressure applies to Raspberry Pi 5, especially at higher memory tiers. If you wanted a board for Raspberry Pi 5 advanced projects, like heavier desktop use, multiple containers, local AI experiments, or more demanding automation, the memory-heavy versions now cost more.

That does not make Raspberry Pi 5 a bad board. It just means you need to think harder about how much RAM you actually need.

If your project is:

  • mostly command line
  • a few services
  • light web apps
  • a simple lab setup
  • a small Raspberry Pi cluster project

then buying the highest RAM tier may not make sense during a memory spike.

How long will the price increases last?

Raspberry Pi says the situation is temporary. The company does not expect memory prices to stay this high forever, and it says it will reverse the price increases when conditions improve.

That is important. This does not sound like a permanent repositioning of the whole product line. It sounds more like a defensive move during a rough memory market.

Until then, Raspberry Pi says it will keep working to reduce the impact on buyers.

Should you buy the 3GB Raspberry Pi 4 or wait?

That depends on your project.

Buy the 3GB Raspberry Pi 4 now if:

  • your build needs more than 2GB but not a full 4GB
  • you want a practical middle option
  • your project is ready now and waiting would slow you down
  • you want to avoid the bigger jump in 4GB and 8GB pricing

Wait if:

  • your project can run on a 1GB or 2GB board today
  • you specifically need a Raspberry Pi 4 4GB or Raspberry Pi 4 8GB and hope prices will ease later
  • you are not starting the project anytime soon

If your workload sits in the middle, the new 3GB version is probably the whole point of this launch.

What this means for Raspberry Pi buyers in 2026

The big takeaway is easy to miss. Raspberry Pi is not moving to 3GB because 3GB is suddenly the ideal amount of memory for everyone. It is doing it because LPDDR4 is expensive, and a 3GB option helps keep the platform more accessible while prices are going up on 4GB-plus devices.

So if you are shopping now, do not ask, "What is the biggest Pi I can buy?" Ask, "What does my project really need?"

That is the smarter way to buy during a memory price spike.

FAQ

Why have Raspberry Pi prices gone up?

Raspberry Pi prices have gone up because the LPDDR4 DRAM used in Raspberry Pi 4 and Raspberry Pi 5 has become much more expensive. Raspberry Pi says the cost of that memory rose seven-fold over the last year, so it had to pass on part of the increase.

Is 4GB enough for Raspberry Pi 4?

Yes, 4GB is enough for many Raspberry Pi 4 projects. You can fit lots of stuff in 4GB of RAM and keep adding services until memory starts getting tight. For desktop use, coding, media playback, home automation, and many server tasks, 4GB is still a comfortable choice. But if your workload is lighter, 3GB or even 2GB may be enough.

Is the Raspberry Pi 4 still worth it?

Yes, the Raspberry Pi 4 is still worth it if it matches your needs and local pricing. It remains a solid board for learning Linux, running small servers, media projects, coding, GPIO work, and maker builds. The only catch is that higher-memory models are less attractive than before because of the current Raspberry Pi memory price increase.

Is it illegal to have a Raspberry Pi?

No, it is not illegal to own a Raspberry Pi. A Raspberry Pi is just a small computer. Like any computer, legality depends on how you use it. Normal uses such as coding, home labs, automation, media centers, and electronics projects are legal in most places.

Final thoughts

The new 3GB Raspberry Pi 4 is really a sign of the times. Memory got expensive, so Raspberry Pi adjusted the lineup instead of forcing every buyer into a costlier 4GB board. It is a practical move, even if it is not the news most buyers wanted.

If you buy based on your actual workload, the new option could save you money and still do everything you need.
