That is pretty obvious if you consider this is just another tweak of the venerable Skylake architecture. By now we have said good bye to the reasonable thermals we enjoyed for a while because, well, if you deliver six of the same cores that'll consume 50% more at the same clock so one hand you slow down the chip when all cores run and on another, you just allow it to consume more.
- blattimwind 8y agoAnd Skylake itself wasn't a new design either, but rather a tweak of Haswell (prominent changes were in the uncore), which in turn was largely identical to SB/IB.
- dantle 8y agoSkylake was a reasonably big core architecture upgrade (a "tock" in Intel terminology). Several new instructions (XSAVE, AVX512, etc.) were introduced. Perhaps you meant Broadwell?
- wtallis 8y agoConsumer Skylake and derivatives didn't get AVX512; that's reserved for the server parts that arrived two years later.
