Below is a performance comparison graph between AMD's CPU 'Xeon' for Intel servers and EPYC. EPYC recorded 1.5 times the performance of 'Xeon 8380' at the time of the 3rd generation 'EPYC 7763', but the performance improved to 2.8 times that of 'Xeon 8380' in the 4th generation 'EPYC 9654'. I'm here.
In addition, the EPYC 9654 has three times the cloud computing performance of the Xeon 8380 and 2.5 times the high performance computing performance of the Xeon 8380.
According to AMD, the 4th generation EPYC is being developed with support from major cloud companies such as Amazon, Google, Microsoft and VMware. These companies are expected to offer products incorporating EPYC.
