Huawei and SMIC quietly rolled out a new Kirin 9000C processor.
Chinese foundry SMIC may have broken the 5nm process barrier, as evidenced by a new Huawei laptop listed with an advanced chip with 5nm manufacturing tech — a feat previously thought impossible due to U.S sanctions.
that's interesting. I think it does still have to do with the amount of power being used for the chip? Like the Steam Deck LCD is 7nm i think and the new one i believe is 5nm, which doesnt make it faster it makes it more efficient and the battery lasts longer as a result.
Looks like they call it “6 nm” which is unusual. Yeah something is improved in the chip, but the marketing isn’t any kind of objective measure of that. Although I imagine most of the improved battery life comes from the bigger battery and more efficient OLED screen.

at the same voltage, smaller transistors don't necessarily lower power because it's easier for electrons to jump across the smaller gaps and leak power that way. but the smaller size usually enables reductions in voltage and shorter wires mean less losses to heat, which entails lower power draw.
