Is 2133Mhz DDR3 or DDR4?

Its LPDDR3. Why mixed information? The Apple website is very clear.

This ^ the Apple website is correct, why would you need to check on a different website?

The one is LPDDR3 the other DDR4, there is no LPDDR4, yet.
LP=low power
The CPU itself supports both, but Apple isn't using DDR4 be cause it consumes more energy.

The Apple website is clear, however the OP touch on something interesting. The Intel CPU's do not officially support LPDDR3 at 2133 Mhz speed, but Apple use that speed anyway.
Even on the i7 CPU's in the 15", Intel only rate LPDDR3 support at 1866 MHz (but DDR4 at 2133 Mhz).
So we get ram speed boost on the new MBP's. The speed jump BTW is 33% as we go from 1600 Mhz to 2133 Mhz. I'll take that! 😎
There is LPDDR4, its just that the Intel CPUs don't support it yet
True
Since its not officially supported by Intel, are we really getting that number or is it just Apple making numbers up? Will the CPU be fully taking advantages from 2133Mhz RAM?

The ram will work at 2133Mhz, no problem at long as the LPDDR3 is rated at 2133Mhz. It is a fairly novel thing to run the Ram at higher speeds, the overclocking community is doing this all the time, and Apple is in full control over the hardware and bios, so no worry. Just enjoy! 😎
Benchmarks will show. I can't imagine Apple lying about it. Why would they? And I am sure that they have sufficiently tested this configuration to make sure it works and is stable. I expect slightly higher random access speed and same bandwidths compared to the DDR4 laptops.
