CPU入面嘅cpuid係hardwired定係(出廠前)programmed?

睇Intel d CPU, Pentium同Celeron係share CPUID (except medocino), 似係hardwire
AMD K7 Barton同Thornton係同一CPUID, K8系列A64同Sempron又好似唔同, 唔通係2種核心?

事關係我一連同4粒0.25um P2拆殼 (300*2, 333, 350)

當中只有一粒333嘅core chip係"正常"0.25um大細

而其餘3粒core chip個金屬蓋都同Slot 1 Celeron-128K一樣大

懷疑Intel係為左方便生產Medocino而將Deschutes嘅封裝一齊改埋, 定有部份Destuchutes P2係奄左嘅Medocino

K8 Sempron好似有自己分開既core

原來真係咁~

呢d我就唔知啦

不過奄割係intel / amd既一貫技倆

就係Deschutes同Medocino嘅CPUID唔同
仲有粒冇鎖頻嘅P2 333 (5.5ns L2)超搞笑, 一超上133MHz FSB就會冇左L2 cache變做covington

PS: 人地拆嘅Deschutes都係細金屬殼...
