I have to buy a laptop with a configuration so that I can run 3-4 virtual machines (Windows 10 & Windows Server 2016) on VMware Workstation.
That's why I planned for a laptop with i5 8th Gen (i5-8250U), 4GB AMD Graphics and 16GB RAM but because of the Optane memory concept, I got confused. I read some articles about Optane memory.
i5-8250U supports Optane Memory, Speed Shift Technology, Hyper-Threading Technology, Virtualization Technology (VT-x), Virtualization Technology for Directed I/O (VT-d) and VT-x with Extended Page Tables.
However, at the end, I am still confused because of correlation of Optane Memory with Graphics Processor for the virtualization process.
How is the Optane memory concept helpful for my requirements?
On behalf of the Optane memory should I compromise with Graphics processor and RAM?

Intel Optane is just a caching technology for regular storage (SSDs, usually HDDs) using their low-latency 3D XPoint flash storage. It is in no way related to virtualisation, the CPU/GPU or other components. It is just there to accelerate the (probably) HDD which is being used in your system by storing commonly used files for faster access.

As you said, Optane Memory is just a caching technology and it is not related to virtualization. Thank you for clarifying my doubt.
I observed in local stores. A salesperson is promoting for a laptop with Optane Memory. If I am right, Optane Memory is not the substitute of RAM so in stead of choosing Optane Memory, if I focus to increase the RAM, it'll be better for overall performace of a laptop including virtualization process.

Exactly. HDD caching existed for long, they are just advertising these things because nobody else would buy a low-class laptop without fancy marketing words. It is typically used in lower-end devices which don't have a SSD as system storage. Your actual best bet is, like you said, upgrading the RAM. That gets you a lot more performance in virtualisation than buying a HDD-based system with Optane.
