honestly i think its good for workstation and stuff and dont expect it to be really really good as its supposed to be a cpu that's more power efficient then the previous generations plus intel only started using 3nm chips around half a year ago so don't expect super high end results another thing is that the electricity to performance ratio is a big difference (around 20 percent less) your probably calling it garbage cuz of this price, if your saying the price to user experience is garbage/not worth it, then ill agree too but the specs for the cpu aint that bad if your not referring to the price but rather the cpu itself

who would've thought Intel would start fabricating a chip which architecture is 3nm after being stuck at 10nm for many years
