It’s the only datapoint available as stated earlier. I did not claim it represented anything. All benchmarks are wrong, some benchmarks are useful. Stream is a total rubbish benchmark but gives you some information re. memory subsystem bottlenecks. Spec int is rubbish for big server workloads. spec rate is a memory bandwidth benchmark.. we could go on. Benchmarking/workload selection is junk science in general. they are useful at uncovering bottlenecks in designs. In this case, assuming the numbers are legitimate, there is something about Zen3 that favors it vs. intel TGL. It was not the case for zen 1 and 2 which lagged intel in ST perf. If that tweak is generally useful it may help others too. Or not. BTW, intel recommended cinebench until they changed their mind for some reason very recently. Not that it matters.
