AS400 to widows server

I have a IBM AS400,  trying to figure out what it would take to replace the AS400 with windows servers.  Just looking a pure processing power not rewriting the application, that is being done now.

I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

I am not sure if there is a published relationship.

AS/400 machines were 64-bit long before any Windows Server.
They could use lots of memory.
The OS/400 operating system was very efficient.

So you want a Server 2016 64-bit on a Windows 64-bit Server machine.
Look at your own app for memory requirements:  Start with 32 GB and be sure you can expand to 64 GB or even 128 GB if necessary.
Use fast (SSD) RAID 10 Drives with lots of capacity now and for the future.

There is no direct relationship.  IBM AS//400 (iSeries / IBM i ) apps don't port to Windows directly.  This means you need to buy or develop software for that platform.  It is possible to produce a general conversion hardware estimate, but it requires some significant analysis of the existing system.  Can you provide hardware details, and basic system performance info?
