I wonder what is Lakefield's target customer? It doesn't look cheap with its packaging, and if it isn't cheap enough it is fighting with 4 Core Tiger Lake.
One thing current Intel chips have lot to improve on it battery life. There's still a 30-50% gap.
Now I know they can close the gap. They have done it with Bay/Cherry Trail. Also the Gemini Lake chips do better.
If they do well on scheduling both of the cores, then we'll get 15W U level ST performance at 3-5W TDP its targeting and better integration along with being able to run flexibly depending on workload means better battery life. That's way better than what the Y chips are doing. It's about 30% behind U chips in ST. Don't forget the big space savings it allows due to integration.
Like I said before, this is a proper return to Tablet chips since they abandoned it with Broxton in 2015. You can do it with Core, but its very clunky. Tablets based on Core weigh much more while the subpar integration sacrifices battery size and design flexibility. Core addresses 13 inch-plus systems while Lakefield will go down to 8-10 inches like every other Tablet, or have a very portable clamshell.
Its a bit unfortunate its taking so long to get Lakefield out. Hopefully future generations improve on timing so to catch up with Core timelines. I believe despite the rocky start this will bring on a new future for x86.
(Also this should result in far better Core M than Core M ever was. Boy that was a disappointment for me. All that marketing hype for what seemed like different binning. It didn't deserve the Core "M" moniker)
