MediaTek’s Dimensity 9000 Plus chipset was the company’s big return to flagship chipsets in the west, and it was a long time coming. The non-Plus version launched in devices like the OPPO Find X5 Pro Dimensity Edition, a China-only exclusive. However, with the advent of the Asus ROG Phone 6 Pro came an additional tier above — the Asus ROG Phone 6D Ultimate. The “Ultimate” moniker obviously implied at the time that it was the superior device, and so, we put both chipsets to the test.
