The impressive part is that it has IPC on par with Raptor Cove, what's holding it to Skylake performance is the low max clocks.
It literally has higher IPC than Zen4, which is an impressive showing for Loongson. I'm guessing it's a very wide design that has to stay at low clocks because it is hampered by the relatively ancient 14nm process it's manufactured on.
You've gotta give credit where credit is due.
But isn't that in only one single benchmark that they've shown? I'd wait for a range of benchmarks before judging it, power efficiency could also be a huge factor too.
Nothing is impressive until there's 3rd party testing. Wouldn't be the first time a company made big claims only for the arch to shit the bed in other workloads.
Is the IPC normalized between RISC and CISC? Otherwise comparing it is pointless.
