A system record apparently for an HP ProOne 600 G5 21.5-inch All-in-One enjoying the company of Intel's Core i9-9900T processor has been discovered on UserBenchmark. The focus of the benchmark is clearly on the processor as the rest of the system does not seem to be fully completed yet. The Coffee Lake desktop CPU has eight cores and 16 threads.
