I'm pretty sure it's a cooling issue. An 8-core CPU running at 5GHz generates a lot of heat - it's likely they can't dissipate it fast enough and encounter thermal throttling issues with higher end chips. I would _assume_ the 9th gen chips are more power efficient than the 8th gen, however, so who knows...
