https://www.semiaccurate.com/2018/05/29/is-intels-upcoming-10nm-launch-real-or-a-pr-stunt/The specs show it runs at 2.20GHz base with a 3.2GHz turbo frequency all for a TDP of 15W. That 15W is of course stated in the name, the -U suffix is for that TDP, -Y for ~9W parts, and others for higher wattages and/or feature sets. In short while this dual core CPU doesn’t clock that high, it also doesn’t pull much power, about what you would expect. That isn’t bad until you notice a few other bits, first off that the i3-8121U doesn’t have a GPU, it is sold as a 2+0 in the parlance (CPU cores + GPU clusters), something Intel has never done before.
If you look at the two 8th gen parts that bracket the 8121U, you will see that the i3-8109U and i3-8130U are both 14nm chips from the Coffee and Kaby Lake, respectively, families. Both are 2C/4T parts with a GPU although Intel won’t give out any details about what the GPUs are any more. In any case they are at least a 2+1 configuration. What is interesting is that the 8130U runs at 2.2/3.4GHz (Base clock/Turbo clock) but the 8109U is at 3.0/3.6GHz because of a nominal 28W TDP.
Let us recap, a 14nm CPU with a GPU is faster within a 15W cap than a 10nm CPU without a GPU running at the same 15W.
Interesting article out from SemiAccurate. Looks like Intel's 10nm is really not working well, despite recent releases. Thoughts?
