As a follow up comparison of Ryzen AI HX 370 processor compared to Ryzen 7840 HS, this posting looks at some Phoronix benchmarks.
I’ve run more than 200 Phoronix benchmarks in analysis using performance counters. I use these clusters to guide the benchmarks chosen trying to pick one from each cluster. In some cases where the benchmark didn’t easily run on Ubuntu 24.04, I skipped to another benchmark rather than debug the original issue. A cluster list from September 2024 below:

The first observation is most all single-threaded benchmarks run faster on the 7840 than on the Strix 370. In contrast the largest differences are among those with largest number of “on_cpu” threads.
There are two outliers that deserve a second look:
- ebizzy is over 5x faster on 7840 than hx 370. This benchmark runs quickly so need to make sure it is running correctly in both instances. I don’t see these ratios in the two SPEC CPU2017 benchmarks also part of this group.
- dbench runs over 3x faster on hx370 than 7840. The on_cpu is almost twice. Again useful to understand if there is another influence affecting this benchmark. Perhaps this one testing something else.
