好似有report話盒面上寫95W TDP...

A week ago there were rumors for it to be 95W.....

That's no good at all, although starting from Nehalem, Intel's TDP is more or less exaggerated.

That means one of the following scenario:
1. Process variation is too large, then some batches of the quad-cores cannot meet 77W TDP target
2. Intel finds out that 77W TDP and 95W TDP shares the same thermal design

如果係後者我笑左

如果係咁倒不如推高d頻算

無乜要推頻住, 因為AMD俾唔夠壓力, 低d頻亦會提高yield (重點)

Same cooler, so have to mark back 95W.

If TDP = 65W may be change to full Al cooler instead of Al/Cu cooler.

呢加好低yield咩

Thermal design power 寫得大唔等於真系用到咁多.,.,.,.,
正如500W火牛你用唔夠500W 唔會爆炸...

肯定唔係高, official delay statement係話yield problem

77W同95W就話, 你mark佢做125W, 睇下仲有無OEM買?

佢呢度話寫就寫95w，實際係77w TDP
睇落Ivy bridge係比Sandy bridge慳d電

係慳電左
不過如果超頻係熱過同級 Sandy Bridge , 電壓上限亦都相應低左

我唔超
諗住買黎做home server，慳電同涼比較重要

我要有VT-d，同埋要有quad core
所以先等Ivy bridge
而家用緊Pentium E5300
