Socket 1567 Xeon Nehalem-EX

No, it is not true either, because otherwise, you discard the level of performance at a given power watt usage.
It is much more complexe than this when you have a dynamic architecture.
It is OK to have high peak of power when you need a high peak of processing FLOPS or MIPS.
Soon, you ll tell us that your platform has better idle, so basically, your platform is better when you don't need it?
If you don't need it, don't buy it ...

well actually i showed before already in a few threads with power calculations of the largest OEM suppliers that it is like that , idle and medio core load is better on istanbul then Nehalem for E series. (not talking about the L series where you really own the market performance/power for the moment)

so not going into discussion about TDP/ACP/MAX TDP, for me they are all useless and I use the official power calculation tools from OEM, that way I can calculate max heat and power and compare real easy between platforms.

Basically, Nehalem and westmere are scaling in Cores and core performance, provide the best today's avaivalble performance when you need it,

keep those words just for a few days more, yes you will remain to have the fastest single threaded performance but there it will end for a large amount of applications.

Your little FUD on the power stuff should be kept on your own processors, you obviously don't understand the difference between electrical max power and Thermal max power, and I know why, your processors don't have a PCU, (power control unit), and you are trying to confuse people on it. Reality is that Nehalem and Westmere are able to make the difference between Electrical and thermal power, and we exploit this to provide maximum performance for a given TDP. Again, stay away from what you don t understand.

comparing a 2009 platform against 2006..... yeah again you are right there is no PCU in the old platform... just a few more days.

And NO i don't work for any CPU brand I just happen to decide what to buy for a few 1000 of both
