We have already seen the consumer-level chips in action but this time, performance of the server-tier KH-4000 CPUs has been showcased. The performance was measured within the SPEC CPU2006 workload and focuses purely on the single-threaded performance. But before we get to the tests, let's take a quick look at the specifications.
