The 7nm Ryzen 5000 C-series ranges from the Ryzen 3 5125C with two Zen 3 cores and a base and boost clock speed of 3 GHz, up to the Ryzen 7 5825C with eight cores and a base clock speed of 2 GHz that can boost to 4.5 GHz.
This cleans the clock of the likes of Intel's Core i7-1185G7, found in some higher end Chromebooks which have four cores and a base clock speed of 3 GHz that can boost to 4.8 GHz.
Generally, the chips are a bit of a snooze and are similar to the Ryzen 5000 U-series, they come with the rather ancient Vega integrated graphics rather than the upgraded RDNA 2 found in Ryzen 6000 mobile chips.
It is hard to see what people expect. It is only a Chromebook and you should not expect that much from them anyway. Otherwise, you are betting off spending cash to get a proper PC.
