Your original comment is false, as Apple's M1 uses LPDDR5, something that has about half the clock rate and transfer rate of current DDR4. It is not DDR5 as is commonly expected when talking about DDR5, and is merely Apple's marketing Kool-aid.
Additionally, Tiger Lake is merely LPDDR-compatible, not forced. You can have a Tiger Lake with regular DDR, and upgrades are easy to do. So, once again, _some_ Alder Lake designs will have soldered LPDDR5, which is low grade DDR4.
This is still not DDR5.
- jeffbee 5y agoYou are seriously confused. The LPDDR4X is faster, not slower, than DDR4. You can equip Tiger Lake with DDR4, but it sucks, which is why the Framework laptop has worse performance and less battery life than all of its competitors.
- ohgodplsno 5y agoVery nice goalpost moving, but still wrong. Specs wise, LPDDR4X would be indeed, able to beat out an average DDR4-2800 under certain circumstances. Those circumstances are quad channel (that the M1 does not have) and 3733 MHz (which the M1 does have). That of course goes out the window if you spec some DDR4-3200 and quad channel it too, which will blow LPDDR4X out of the water. And of course, once again, you make this a laptop thing when the original post is about people believing the M1/M2 would scale linearly with power usage and be a strong contender to desktop CPUs. So, no, there's no DDR5 in the M1, its LPDDR4X is not faster than DDR4, and please stop trying to force feed me the Apple kool aid, this has never been about battery life.
