I’d be much more interested in testing of more real workloads.
99.99% of computing involves branch prediction, caching, frontend decoding capacity, memory bandwidth, and more. Usually the bottleneck.
Unless you just want to run highly artificial benchmarks, you’d always want a well-fed, high-efficiency processor that has a lower theoretical maximum, versus a severely bottlenecked, DRAM-waiting processor even if the latter has 2x faster ALU performance.
