Which doesn’t really mean a different power consumption.
Which also doesn’t mean a different power consumption
It is the other way around, with Intel boosting higher. But I don’t know if it would boost a core if the other one is partially loaded. So it should be more like this than:
Case 1: max single threaded load
Intel: core1 3,5Ghz, core2 0,8Ghz
AMD: core1 3Ghz, core2 0,8Ghz
Case 2: max multithreaded load:
Intel: core1 3Ghz, core2 3Ghz
AMD: core1 3Ghz, core 2 3Ghz
Case 3: a strong single thread load and a light background loads
Intel: core1 3Ghz, core2 1,2Ghz
AMD: core1 3Ghz, core2 1,2Ghz
Why I think it is more this way? Since Intel turbo boost implies that the turbo boost applies to the stressed cores, so I understand that as a 'once another core is loaded with a thread, the turbo boost would be lowered to what the turbo boost for the total of the loaded cores is.
A dual core is a bad example, since there will always be background programs running on the not used core when the first core is fully loaded.
Another possible way that turbo boost could work, is that it would still boost the fully loaded core even if another core is slightly loaded, but it won’t go all the way (since there is another core running and producing heat, the situation would be suboptimal for reaching full single core turbo boost). So than case 3 would become:
Intel: core1 3,3Ghz, core2 1,2Ghz
AMD: core1 3,0Ghz, core2 1,2Ghz
But I still can’t see a power saving in that higher single core boost, since on one hand AMD is running at lower clockspeed in case 1 (very hypothetical) and case 2 (more realistic), a lower clockspeed requires less power and less heat production, but it has also lower performance so it will need power for a longer period of time. So on the power side, I can’t think of a clear answer. On the performance side it is easier, since IPC of AMD and Intel is close this time, than you can see that the single core turbo would increase single core performance. Which has its use cases, like old unoptimized games, but for recent games, that would depend on the core count of the CPU compared to what the game is optimized for (GTA V dual core, more recent games are more optimized for quad cores, and there are already games having benefit from more than 4 cores, but those remain exceptions at the moment). Also it depends on how the turbo boost works, completely lowering a complete level once an extra core is activating, or only lowering a bit as long as it fits in the TDP settings. The latter one, games that have 1 big primary thread and the other ones are very small, in that case with the latter interpretation of turbo boost, it would have a slightly better gaming performance because the primary thread will get boosted as far as the situation allows. But if it is notable is something else.
