You're right -- Haswell can support 32GB of DDR3. BUT, LPDDR3 is not the same as DDR3 despite the "DDR3" in the name.
It's not about the processor family. LPDDR3 as a technology is limited to 16GB max. Four banks of 32Gbit. It can't address more than four banks, and the address limit is 32Gbit per bank. LPDDR4 supports 32GB now, and 64GB in the future -- but won't be implemented until likely the beginning of 2018 with Cannon Lake.
Apple could choose to use DDR4 (note the lack of LP). However, not only is the RAM more power-hungry, but the related circuitry that would be needed for it is as well. Hard to tell what kind of impact we're talking on battery live -- maybe 30%.
We've done about four pieces on it. Here's some non-AI sources.
Didn’t know about that, I will check it later. Good to know though.
speaking about delay of Cannon lake, I saw a Chinese news source, who claimed themselves had asked this to Intel China, which said it’s only a rumor, the production time will be as usual. although that’s the only source so far. https://tech.sina.cn/2017-09-21/detail-ifymenmt5867445.d.html?from=wap
UPDATE: Intel WILL Ship CannonLake before end of 2017 !
"We're on track to ship our first low-volume 10-nanometer part by the end of the year. That will be followed by the initial ramp in the first half of 2018, with both high volume and system availability in the second half of 2018."
So why are the 8th gen 15W quad (13) and 45W 6-cores (15) not an option, along with Vega mobile graphics, in the meantime till Coffee Lake? Sure it only supports 16GB LPDDR3, but that's the same situation as now. The extra cores and GPU update would be a big help.
