Heart-warming comments from Issue #384 of Linley's Processor Watch:
Oracle's Sparc T5 also has 16 CPUs, but it implements eight threads per
core, versus Fujitsu's dual-threaded CPUs. Moreover, the Sparc T5 now
supports glueless multichip scaling to eight sockets, whereas its
predecessor and the Sparc64 X gluelessly scale to only four sockets.
Both companies trumpet the high performance and reliability of their
processors. It's the main reason for designing their own chips (at
considerable cost) instead of simply buying Xeon server processors from
Intel like everyone else. Although a Xeon processor is probably more
power efficient, it lacks the same features for RAS (reliability,
availability, scalability).
