The R40 and R40S Pro come up constantly alongside the R36 family — and buyers reasonably ask whether “R40” means a newer or better device than the R36 Ultra. Here’s what these handhelds actually are and how to choose.
What is the R40?
The R40 is a budget Linux-based retro handheld from the same broad ecosystem as the R36S and R36 Ultra. The higher number does not automatically mean newer or more powerful — in this market, model numbers are branding, not a generation ladder. What matters is the actual spec: screen size and panel type, controls, battery, and firmware.

R40 vs R40S Pro
- R40 — the standard model: IPS display, dual analog sticks, USB-C, MicroSD expansion.
- R40S Pro — the uprated variant, typically with a bumped configuration. See the R40S Pro listing.
Because batches vary between sellers, always read the exact listing spec rather than assuming “Pro” guarantees a particular upgrade.
R40 vs R36 Ultra — which should you buy?
| R36 Ultra | R40 / R40S Pro | |
|---|---|---|
| Screen | 4.0″ IPS | IPS (check listing) |
| Track record | Very widely reviewed | Fewer independent reviews |
| Emulation | Similar class — NES through PS1 | |
| Best for | The safest all-round pick | Buyers who want to try the R40 line |
Our take: the R36 Ultra is the safer recommendation for most people simply because it’s so widely reviewed — you know what you’re getting. The R40 line is worth a look if a specific listing offers a spec or price you prefer. Compare all the R36 options in our model comparison.
What both do well
- NES, SNES, Genesis, Game Boy / GBC / GBA — flawless.
- PS1 — the comfortable ceiling; most 2D and lighter 3D titles run well.
- Arcade classics — a highlight on any handheld in this class.

Buying advice
Whichever you pick, the checks are identical: confirm the screen size and IPS panel, read the 1- and 2-star reviews, ignore “40,000 games included” claims, and make sure there’s a real return window. Our clone-spotting guide and where-to-buy guide walk through it all.
Bottom line
Don’t read “R40” as a straight upgrade over “R36” — judge each listing on its actual specs. For most buyers the R36 Ultra is the best-documented, safest value; the R40 is a reasonable alternative if its listing suits you better.
Our pick: the R36 Ultra
