Earlier quoted context omitted.
Yes, you're right, the EnergyCore isn't 64-bit, and of course there are other differences between the architectures. Perhaps you could actually provide some information on how those differences might affect the two systems' capabilities. Or are you just here to snipe at others?
My role here is to prevent people going away with misguided information presented as fact and propagating it elsewhere. Or maybe I should just keep my great big trap shut and sit here feeling smug instead. There is too little information provided on the two examples to be more precise, otherwise I would have gone into it. All we know is the Boston machine is EnergyCore-based - now that could be a 1000 which is Cortex…
In other words, you don't really know enough to say there's a difference. What we do know is that they're the same basic architecture and instruction set, at very similar process levels, so it's not at all unreasonable to estimate that the performance difference is proportional to the clock-rate difference. That clock-rate difference is probably dwarfed both by Viridis's 50% nodes-per-rack advantage and Copper's 2x memory-per-node advantage, so the quibble just wasn't worth it. Thanks for adding so much to the discussion.
