Tried to find some info on this but the comparisons are for slower 3.0 m.2 drives. The best 4.0 drives may be faster than this boot drive on a 4.0 system. 3.0 you may see some improvement.
"Let us be clear, for any use other than as a write log device, we cannot recommend the Intel Optane DC P4801X 100GB M.2 device. At $2.60 per GB it is too expensive when solid performing NVMe SSDs are approaching $0.10 per GB today. If you do not need a dedicated heavy write-log device, get something else."
Yup. And while some swap setups could be an additional benefit; using this as a complete system-to-RAM setup would probably be the most interesting... but not at this price point. There have been optane deals with far less capacity, at far less of a price, that is better suited for an OS running solely on RAM. I have a NUC with only 4GB RAM hard soldered, with no other option except to take up the only m2 slot with optane... IF the BIOS is compatible. But running antiX Linux to a total of 12GB RAM, and not even needing a hard drive, is screaming fast.

This 58GB drive has an Endurance Rating (Lifetime Writes) of 635 TBW
Most 1TB drives have 1/3 of that or less.

Are there any use cases apart from vram
It was designed for specific customer needs as a boot/cache device.
I tested an early combo Optane drive and it did boot fast. But not faster than a 4X4 m.2.
Still! Intel makes reliable products for its commercial customers.
If these get really cheap, they will make great boot drives for dependability/long term.
Going fast is not always the best answer in life.
I remember desktops lasting so long you could not take it anymore (I want something new).
