In short

RG CubeXX is a 3.95-inch 720×720 IPS Linux handheld: H700, 1GB RAM, 3800mAh / 6.5 hours (OEM), 246g. Buy it for that official page. Skip it if you want RG556’s Android T820 / AMOLED sheet or a Windows PC.

Who it is for

  • Players who want a first-party 1:1 720×720 Linux handheld with H700 printed on anbernic.com.
  • Shoppers comparing 246g / 3800mAh / 6.5-hour OEM claim against Android RG556 / RG 477V sheets.
  • People who will accept unpublished nits, TDP, and Hz.

Who should skip it

  • Anyone who wants Windows, SteamOS, or Android. The page prints Linux 64-bit.
  • Buyers of RG556 (`/handhelds/anbernic-rg556/`) or RG 477V (`/handhelds/anbernic-rg-477v/`).
  • People who need more than 1GB RAM on the OEM sheet.
  • Nintendo-first players.

Key differentiators

  • 3.95-inch IPS, OCA full lamination, 720×720.
  • H700 quad Cortex-A53 1.5GHz + dual-core G31 MP2; Linux 64-bit.
  • 3800mAh Li-polymer; OEM 6.5-hour battery-life claim; 5V/1.5A C2C.
  • 246g; 15.72 × 8.96 × 1.79 cm; dual TF slots up to 512GB; HD TV connection named.

Caveats

  • 6.5 hours is ANBERNIC’s published battery-life line, not a Valve-style gameplay curve.
  • Nits, TDP, HDR, and refresh Hz are unpublished.
  • Storage is 64GB TF/MicroSD on the page — not UFS. RAM is 1GB.
  • $64.99 is a live cart.
  • GadgetShowdown has not lab-tested RG CubeXX.
