It's a lengthy document. You're using your phone while the PC runs a 3DMark CPU profile, and the clock speed is only around 380 MHz.
It's all fine. At the article's conclusion it mentions DDr5 builds on what DDr4 started. This means only those who can handle speeds between 3200 and 3600MHz might notice a noticeable boost to DDr5 at 4800MHz. Someone capable of 4400MHz would see just a small improvement—about 1.5%. That might not justify the effort. Most users with Corsair LX3600 won't reach those speeds, so it doesn't deliver the promised performance. Many discussions exist about people struggling to hit 3600MHz or even 4400MHz and failing to match DDr5's capabilities.
