    A Nuvia ( arm , mostmár Oryon core in Snapdragon X Elite )
    magok elemzése a sajtos-chipses fiúktól ( és a zen4 -el is össze van hasonlítva! )
    (Amúgy TSMC 4 nm -en alapul - és majd a 4nm-es zen5-ös Strix Point lesz az igazi versenytárs. )

    Qualcomm’s Oryon Core: A Long Time in the Making

    "On paper, 12 big Oryon cores should be a formidable opponent for both AMD’s eight Zen 4 cores and Meteor Lake’s 16 cores of various types."

    "Oryon’s indirect predictor isn’t as big as Zen 4’s 3072 entry indirect branch predictor and can’t track as many targets. But unlike Zen 4, there is no slowly increasing penalty after 32 targets for a single branch. This likely means that Oryon doesn’t use a similar mechanism to Zen 4. Now comparing Oryon to Golden Cove and they are very similar to each other but Oryon can track more targets than Golden Cove can."

    "As test sizes exceed AMD’s L2 capacity, Qualcomm’s three L2 instances can provide 16% more bandwidth than AMD’s L3. Snapdragon X Elite has three 12 MB L2 instances for 36 MB of total capacity. Using three L3 instances makes it easier to provide high bandwidth too."
