V4 has 8 cores instead of 6.
But well, it's a server grade config on purpose!

AFAIR it's a double Xeon E5-2620 v3.
With modern CPUs frequency is not so significant.
Our latest batch of servers are: Intel(R) Xeon(R) CPU E5-2620 v4 @
2.10GHz (so v4 instead of v3, but the difference is probably minimal).

The actual hardware requirements will depend on your use case. But for
comparison, our production servers are:
* 16 cores (hyper threaded, 32 threads)
* 128G RAM
* 1.5T of SSD storage

The current size of our jnl file in production is ~670G.
Hope that helps!
