OnePlus Ace 5 Ultra surfaces in Geekbench with a confusing chipset choice

Last week we heard that OnePlus is working on a third member of its Ace 5 family, following the already available Ace 5 and Ace 5 Pro. Back then, this was rumored to use MediaTek's still-unannounced Dimensity 9400e SoC, which is the lower-bin of the 9400 family.

But now a new OnePlus device has surfaced in the Geekbench database, and this one is powered by the recently unveiled Dimensity 9400+, which is the higher-bin model of the 9400 family. And that's rather confusing, as it's rumored to be launching in China as the OnePlus Ace 5 Supreme Edition (such names usually get translated into English as "Ultra").

So we have an Ultra phone that's very close in its Geekbench scores to the OnePlus 10 Pro, but not quite there - as the Pro uses the Snapdragon 8 Elite SoC. Anyway, the presence of the Dimensity 9400+ is certain given the 3.73 GHz frequency of its Prime core - that is in fact the one quantifiable improvement it has over the 'vanilla' 9400, which topped out at 3.63 GHz.

The prototype which ran the benchmark had 16GB of RAM, but of course OnePlus could choose to offer it with other memory amounts as well. Unsurprisingly, it runs Android 15. This phone is rumored to be released in China by the end of this month. Unfortunately, international availability isn't a given. We'll keep you posted.
