ROG Ally vs ROG Ally X: Which Should You Buy in 2026?
ASUS sells two ROG Ally models: the original ROG Ally and the ROG Ally X. The Ally X costs more but fixes the original’s biggest problems. If you’re deciding between them, this comparison covers what actually changed and whether the upgrade is worth the price difference.
Specs Comparison
| Spec | ROG Ally (Original) | ROG Ally X |
|---|---|---|
| Processor | Ryzen Z1 Extreme | Ryzen Z1 Extreme |
| RAM | 16GB LPDDR5X | 24GB LPDDR5X |
| Storage | 512GB SSD | 1TB SSD |
| Battery | 40Wh | 80Wh |
| Display | 7″ 120Hz IPS | 7″ 120Hz IPS |
| Price | ~$499–$599 | ~$799 |
The Key Difference: Battery Life
The original ROG Ally had a 40Wh battery — critically small for a device as power-hungry as the Z1 Extreme chip demands. Real-world gaming sessions lasted 1.5–2 hours under load. That’s not enough for most travel use cases.
The Ally X doubled it to 80Wh. Real-world sessions now run 2.5–4 hours under gaming load — usable for a commute or a flight. This single change is the main reason the Ally X exists and the main reason to choose it over the original.
RAM: 24GB vs 16GB
The Ally X ships with 24GB of LPDDR5X RAM vs 16GB in the original. The extra 8GB matters in two scenarios: running Windows with multiple apps open alongside a game, and future-proofing for games that increasingly recommend 16GB+ RAM. For current gaming in 2026, 16GB handles most titles — the upgrade is useful rather than essential.
Storage: 1TB vs 512GB
The Ally X ships with 1TB, the original with 512GB. Modern AAA games average 50–100GB each. 512GB fills up with 5–10 large games. 1TB gives more headroom. Both models support microSD expansion, so the storage difference is manageable — but having 1TB built-in is more convenient than adding a card.
What Didn’t Change
Same processor (Z1 Extreme), same display (7″ 120Hz IPS), same operating system (Windows 11), same game compatibility. Performance in games is identical between the two models. If you’re choosing between them for gaming performance, they’re the same device.
Should You Buy the Original or the X?
Buy the ROG Ally X if:
- Battery life is important — the 40Wh original is genuinely limiting
- You want 1TB storage and 24GB RAM without adding accessories
- You’re buying new at market price (~$799 vs ~$499–$599)
Buy the original ROG Ally if:
- You find it at a significant discount ($300–$350 range used/refurbished)
- You primarily play docked or near a charger where battery life is irrelevant
- Budget is the limiting factor
At $200 off, the original Ally is a reasonable value. At full price, the Ally X is worth the premium — the battery improvement alone justifies it for portable gaming.

Bottom Line
Choose the ROG Ally X. The original’s 40Wh battery is a serious limitation for portable gaming, and the Ally X’s 80Wh battery fixes it while adding more RAM and storage. If you find the original at a steep discount and primarily game near a charger, that changes the calculus — but for most buyers, the X is the right version.
