Meanwhile they are NOT laser-focusing on doing more of Lunar Lake, with its on-package memory and glorious battery life.
Intel called it a “one-off mistake”, it’s the best mistake Intel ever made.
- bryanlarsen 10mo agoIntel is claiming that Panther lake has 30% better battery life than Lunar Lake.
- dudeinjapan 10mo agoPerhaps in a vacuum… On package memory is claimed to be a 40% reduction in power consumption. To beat actual LL by 30%, it means the PL chip must actually be ~58% more efficient in an apples-to-apples non-SoC configuration. Possible if they doped PL’s silicon with magic pixie dust.
- wtallis 10mo ago> On package memory is claimed to be a 40% reduction in power consumption. 40% reduction in what power consumption? I don't think memory is usually responsible for even 40% of the total SoC + memory power, and bringing memory on-package doesn't make it consume negative power.
- phonon 10mo agoLunar Lake had a 40% reduction in PHY power use by using memory directly onto the processor packaging (MoP)...roughly going from 3-4 Watts to 2 Watts...
- ac29 10mo agoDo you have more information on that? I have a meteor lake laptop (pre-Lunar Lake) and the entire machine averages ~4W most of the time, including screen, wifi, storage and everything else. So, I dont see how the CPU memory controller can use 3-4W unless it is for irrelevantly brief periods of time.
- phonon 10mo agoThat's peak usage. I don't know how reduced the PHY power usage is when there aren't any memory accesses. For comparison, the peak wattage of Meteor Lake is something like 30-60 Watts. https://www.phoronix.com/review/intel-whiskeylake-meteorlake/12#:~:text=On%20average%20the%20Core%20Ultra,than%20the%20Core%20i7%201185G7. https://www.phoronix.com/review/intel-whiskeylake-meteorlake...
