The new Poco X7 Pro Iron Man edition sports a MediaTek Dimensity 8400-Ultra processor, a mid-range companion to the chip maker’s flagship Dimensity 9400. Neither company hasn’t told us what’s new with the Ultra version, but the clocks and specs look the same; my guess is simply improved cooling, which should help realize the chip’s maximum performance for as long as possible.

MediaTek’s Dimensity 8400 is an interesting chip, aping a fair bit of its “all big core” design from the latest flagship silicon. There are no little CPU cores here, something we’ve seen in the Dimensity 9400 and Qualcomm’s flagship Snapdragon 8 Elite. In fact, it’s built entirely from eight of the latest mid-tier Arm Cortex-A725 cores, with clock speed and cache differences allowing them to scale across performance and efficiency points. One A725 has a 1MB L2 cache and 3.25GHz peak clock, three cores have a 3.0GHz clock and smaller 512kb cache, and four lowest power cores peak at 2.1GHz with a smaller 256KB L2 cache.
