I hate this kind of journalism. Just by using the term sources, you can just write anything nowadays, and forget about how much it affects the other party. Dimensity chipsets have been performing really well for some years now. Without full proof, how do you even write the article? Whataboutism at its best.
I've been saying again and again that benchmark scores aren't everything. There's no point bragging about it when you can't get the most out of it, especially when using Desktop Mode.
Due to thermal issues, MediaTek may have to lower the Dimensity 9300's performance targets. Its root cause is believed to be its unique octa-core design with four Cortex-X4 and Cortex-A720 cores with no efficiency cores.
