i checked a few h610 and w680 models, none of them have added support for bartlett lake.
so for the consumer market, dont even think about it.
it seems intel has updated the bartlett lake product pages and added the official pricing.
the bartlett lake sku are quite competitive in the current consumer market.
btw i guess that unless you do a massive undervolting raising pl2/pl1/iccmax, the all pcore frequency will be lower in the real world.
