A CPU sizing only has to be performed in addition to the memory sizing if a massive amount of users working on a relatively small amount of data is expected
. Choose the T-shirt configuration size that satisfies both the memory and CPU requirements.
The CPU sizing is user-based. The SAP HANA system has to support 300 SAPS for each concurrently active user. The servers used for the IBM Systems Solution for SAP HANA support about 60 - 65 concurrently active users per CPU, depending on the server model.

That the CPU sizing has to be adjusted so that the server load does not exceed 65% in average (i.e. to obtain the maximum number of users per server, the absolute server SAPS capacity has to be multiplied by .65).
