Considering the Raspberry Pi CM5 is available with up to 16GB RAM, it should come as no surprise that the Raspberry Pi 5 also got its own 16GB LPDDR4 RAM upgrade. But the extra memory does come at a premium since the new board sells for $120, a $40 markup compared to the Raspberry Pi 5 with 8GB RAM.
The extra memory should bring the user experience closer to a desktop machine for browsing the web with multiple tabs, checking emails, watching YouTube videos, and more all at the same time. Besides multitasking, the 16GB RAM may also be beneficial when running generative AI workloads like LLMs and VLMs which are known to be memory-hungry.

As far as I can tell, the only difference is the RAM capacity. When I reviewed the Raspberry Pi 5 with 2GB RAM and compared it to the model with 8GB, I noted a lower power consumption which ended up being because of the BCM2712D0 SoC being used instead of the BCM2712C1. Based on the photo provided by Raspberry Pi, the new 16GB model relies on the D0 processor, so the power consumption should be similar or very slightly higher due to the higher memory capacity. The silkscreen appears to be changed too since the area used to select the RAM capacity with a resistor has no markings.
I haven’t asked for a review sample because the performance reported by benchmarks will be the same. If you are already happy with a Raspberry Pi 8GB, there’s really no reason to upgrade. But if you encounter frequent out-of-memory (OOM) messages or performance degradation due to swapping, switching to 16GB may make a big difference.

I can buy 16 Go SODIMM DDR4 for $25.
RPi 5 with 2 Go is $50. Shouldn’t it be $75?
Should we hope RPi 6 will support LDCAMM2 (64 Go already available but far too expensive)?
You forgot step 3: $$$profit$$$
Your SO-DIMM consists of eight inexpensive 16Gb DRAM chips.
The RPi 5 is built around a VideoCore SoC featuring a really incapable memory controller (single channel, 32-bit only) and can not access more than a single LPDDR chip. Which in case of 16GB DRAM means one really expensive 128Gb chip.
> Should we hope RPi 6 will support LDCAMM2
CAMM2 defines two memory channels, 64-bit each. The current SoC on RPi 5 can only address a single 32-bit memory channel.
So unless RPi Ltd. manages to get new VideoCore SoCs from BroadCom with a more beefy memory controller or switches entirely to a new platform (LP)CAMM2 modules are either incompatible or a pure waste (since 3/4 of the RAM on the module couldn”t be addressed anyway).

Doesn’t seem so. At least with a new firmware from yesterday the 16GB version is a little faster compared at least to the 8GB version (which always was slower than the 4GB versions).
It’s likely the 8GB version would perform about the same with the new firmware unless they changed something else. Raspberry Pi told me they did not change anything apart from the higher memory capacity.
