AMD 印象中自 K7 以來, 都是 64k+64k L1, L2 則是從入門款 128 K~256K, 主流的都是 512 K+
intel 則是有變動, 再 P-II/P-III 時代是 32k+32k 的 L1, 256k or 512K 的 L2,
P4 則因為 netburst 架構而有變動, L1 改成資料 & 追蹤快取, northwood & Willamette 只有 8K 的資料快取以維持低週期的延遲, 再 prescott, intel 加大 L1 資料到 16K, trace 兩者皆是 12 kuops
到了 banias/dothan/yonah, 以至現在的core, L1 都是 32k+32k 的設計了L2 intel 則是越加越大...Willamette印象中只有 256K, northwood 是 512K, prescott/5系列/banias 是 1M, dothan 以來, intel 主流的 CPU 大多是 2M, 現在的core 已經有 2m+2m 的了...

Cain was the first man ever to strike down another... and when the Lord came to him and said ‘What have you done!?’, Cain could not hide his crime. For the voice of his brother’s blood cried out from the very ground
The world has been your battlefield, everywhere you go. The blood of brothers and sons screams out against you. Perhaps you cannot yet hear it, because the soil is not your own, but you will... you will
