    A lunarLake és az előző generáció között teljesen más tervezési filozófiát
    és valószínüleg teljesen más tranzisztor könyvtárt használtak ( TSMC3 vs. INTEL4 )

    George Cozma:
    Again, back to the previous generation, you had a GPU, tile, an SOC tile, and an iGPU tile. On Lunar Lake, that’s now all been reintegrated on to a single die. What was the why move back to a more monolithic design for those parts of the design?
    Arik Gihon:
    Yeah. So it was a trade off, actually. When you start building the project, you start to think which transistor you want to put on which node. And since we have selected the entry, we could fit, more transistors into entry in one monolithic die. And the second is that it was an optimized die just for a specific segment.
    You don’t need to stay for the entire family and up to desktops with that. And also, we could just put all of the transistors, all of the compute transistors, on the same die very close to the memory and therefore gain latency and gain performance. So you both gain good process for all of those as well as for the SoC components and the memory components, and closer to the memory.
    George Cozma:
    And so then sort of a follow-up to that, why did you leave the what you’re calling the platform controller die, as its own separate die? Was that because the stuff on that die doesn’t scale as well with newer nodes?
    Arik Gihon:
    It just didn’t need to scale. Those transistors are usually controllers for IOs. They can fit nicely into N6’s process, and the IOs are working there very good. So it was a nice partition.
