What is maximum heap size for 64 bit or x64 JVM is it 8gb or 16GB?
As no system currently have 2^64 bit of physical memory or RAM and often high-end servers have memory around 8G, 16GB or 32GB. Theoretical maximum memory for x64 machines is 2^64 bit but again it depends on how much your operating systems allow.

What’s the maximum heap size for 32 bit Java?
“For a 32-bit process model, the maximum virtual address size of the process is typically 4 GB, though some operating systems limit this to 2 GB or 3 GB. The maximum heap size is typically -Xmx3800m (1600m) for 2 GB limits), though the actual limitation is application dependent. For 64-bit process models, the maximum is essentially unlimited.”
