PayPal’s 2015 ARM-server story was a real but unquantified deployment: the company had validated Applied Micro’s 64-bit X-Gene servers and was running a real workload on them. The report did not say how many servers PayPal used, identify that workload, or establish that the systems remain in service.
What PayPal deployed in 2015
On April 29, 2015, Data Center Knowledge reported that PayPal had deployed servers using Applied Micro’s 64-bit X-Gene ARM processors. Applied Micro CEO Paramesh Gopi said PayPal had “deployed and validated X-Gene” and that the servers were “running a real workload.”
That is evidence of validation and actual workload use, but not of a large-scale rollout. The report said the deployment’s scale was unclear. It did not disclose the server count, the workload’s exact purpose, or whether PayPal expanded the deployment later.
What the cost claims mean—and do not mean
Gopi told Data Center Knowledge that the X-Gene-equipped units at PayPal cost approximately one-half as much as traditional data-center infrastructure hardware and had one-seventh the annual running cost. These are Applied Micro’s claims as reported in 2015, not independently verified measurements of PayPal’s deployment. The report does not provide the hardware comparison, operating assumptions, or methodology needed to treat the figures as a controlled cost analysis.

Applied Micro presented ARM servers as a possible lower-cost alternative to x86 for data-center work. Its executives pointed to web-tier servers, storage, and in-memory databases as potential target workloads. Those examples describe the vendor’s expectations; the report did not say that PayPal used X-Gene for any of them.

The X-Gene report is separate from an earlier PayPal ARM deployment described in ARM’s 2014 annual report, published in 2015. That account says PayPal used an HP Moonshot system with a Texas Instruments 66AK2Hx processor to analyze payment-event data in real time.

| Example | Processor and platform | What the source establishes | Evidence type |
|---|---|---|---|
| Earlier system, described in ARM’s 2014 annual report | TI 66AK2Hx in HP Moonshot; the processor combined four ARM Cortex-A15 cores with eight C66x DSP cores | ARM said it analyzed thousands of event streams and could process three million transactions per second, totaling 25 terabytes per hour, to detect fraud, glitches, and other anomalies. These are figures in ARM’s company report, not an independent benchmark. | ARM’s own annual report |
| X-Gene deployment, reported in 2015 | Applied Micro 64-bit X-Gene ARM processors in servers | Applied Micro’s CEO said PayPal had validated X-Gene servers running a real workload. Scale and workload details were not disclosed. | Industry report quoting a vendor executive |
The two examples show distinct hardware configurations and different kinds of evidence. The available accounts do not provide a controlled performance or cost comparison between them.

What is—and is not—known about the deployment
- Established: In 2015, PayPal had validated X-Gene-based servers and was running a real workload on them, according to Applied Micro’s CEO as reported by Data Center Knowledge.
- Not disclosed: The number of X-Gene servers, the exact workload, or whether PayPal expanded the deployment.
- Not established: Whether PayPal still operates either ARM system or what hardware replaced them. These accounts document historical use, not current operations or present-day hardware availability.
- Not independently verified: The 2015 price and annual running-cost comparisons attributed to Gopi.
