Hardware TCO comparison

IBM Power Hardware vs PowerVS and x86

Compare IBM Power hardware with PowerVS and x86 on the costs your workload will actually create. Match the workload first so the cheapest-looking option does not become the expensive one.

The useful comparison is what your workload costs to run on each option. PowerVS meters IBM i, AIX, and Linux resources instead of selling you the physical server. x86 and cloud prices change by provider, region, and commitment, so a fair comparison begins with the same workload and service level.

AIX buyers have two IBM Power cost models

An on-premises AIX plan starts with a configured IBM Power server and adds AIX Software Maintenance, support, and migration. Power Virtual Server meters the processor, memory, storage, and AIX resources assigned to the instance.

Compare the two models in the IBM AIX Server Cost guide.

What drives the IBM Power hardware comparison

IBM i dependencyIf your workload requires IBM i, x86 is not a real substitute. The comparison narrows to on-premises Power and IBM Power Virtual Server.
Utilization patternSteady, predictable load favors owned hardware's amortized economics; spiky or seasonal load favors pay-as-you-go cloud pricing.
Operational controlOn-prem ownership keeps data, firmware, and maintenance timing in your hands; cloud shifts that control (and that overhead) to the provider.
Capital vs. operating costOwned hardware is capital-heavy up front; cloud and subscription models shift the same spend into an operating expense.

Why one hardware price cannot settle the comparison

No honest comparison can use one fixed headline number for PowerVS, generic cloud, and x86. Each changes with configuration and contract. When IBM publishes a number for a specific entry configuration, we cite that number and keep its limits attached.

Use IBM's own Power Cost Estimator tool and current IBM Power Virtual Server pricing pages for a configuration-specific comparison; those numbers change frequently and are best pulled live rather than cached here.
