"Overall you have a CPU that really doesn’t win at anything compared against a year or so old AMD design but using some well chosen benchmarks and descriptions can be made to look like a ki---r part. It isn’t. When you add in the software complexity needed to make the whole design not be a huge step backward, there is absolutely no reason for this to exist on the desktop. On laptops you could make a case for meager battery life gains but those would be overwhelmingly outweighed by the added software complexity. Intel copying ARM’s big little is just stupid and should not have been done."
