As we previously noted, the “X” in the model name appears to stand for “extra,” “extend,” and “expand,” the three buzzwords ASUS plopped onto its YouTube video discussing the ROG Ally X. If the leaked slide is accurate, part of the expansion (or extra, if you will) includes a bump to 24GB of LPDDR5-7500 RAM and 1TB of SSD storage in the standard M.2 2280 form factor.
The current ROG Ally (non-X) features 16GB of LDPPR5-6400 RAM and 512GB of SSD storage in a smaller M.2 2230 form factor. So we’re looking at a 50% increase in the amount of RAM (8GB more), which is faster to boot, and twice the storage in the more accessible M.2 2280 form factor. That latter bit should make storage upgrades a little cheaper, as there are way more M.2 2280 options in the wild than there are M.2 2230 SSDs.

It appears as though the ROG Ally X will also ditch the ROG XG Mobile port for connecting an external GPU and replacing it with a USB4 port supporting DisplayPort 1.4 connectivity and Power Deliver 3.0. Other changes include 23% smaller and 50% thinner fans, a better D-pad, a slightly thicker chassis, and an overall heavier design checking in at 678 grams (versus 608 grams).
