NovaLace is supposedly CuguarCove from what the P-Core engineer said recently. As for NovaLake, I assumed it was a new core but I wasn't sure about PantherLake but I also suspected it was something like LionCove or its improvement.
Question for 100 points. Is PantherLake a new core or slightly improved or the same as LionCove? Is NovaLake a different core than the one in Panther? Good question.
LionCove has a very good L2 and a pretty good L1-1.5-D subsystem. Maybe L1.5-D could be a bit better but it's not bad. L3 is a nightmare. If the same team that did the LionCove core took on L3 it would be a lot better.
Are there any sources stating which parts of ArrowLake were designed by...
Yes, I knew about the new design tools that Intel had switched to and that were used in the LionCove project, among others. But is that the main reason?
Could you please explain to us the reason for the bad PPA of the LionCove core? Is there more to what we already know?

The LionCove core itself is a reset if we are to strictly adhere to Intel's tradition in this matter.
It is a bit strange that the C&C analyses show that the predictor is also lame in some respects compared to RaptorCove, even though Intel claims that this part is 8x larger in some respects...
In the case of Skymont, it is more difficult for me to recognize the structures. I found the description, but it looks like someone confused Front-end with Back-end (I think).
In ArrowLake's LionCove variant, there is a larger space between the lower half of L2 and the upper half of L2, so...
