"Merom" TDP Not All That

"Merom" runs hot, "Yonah" might be the better chip for notebooks
Intel began releasing specifications of the new
processor to its motherboard partners today. For those expecting
to increase performance over Yonah while simultaneously decreasing the thermal envelope, think again.
The top of the line
processor, the T2700, has a TDP of 31W at 2.33GHz clock frequency. All Core 2 Duo
processors have a TDP of 34W, including the lowly 1.66GHz T5500. In comparison, the 1.66GHz Yonah rings in at 27W.
Surely with Enhanced Speed Step these numbers get better, we'd think. In "Battery Mode," all
processors clock down to 1GHz and 0.75V -- yet amazingly the TDP is still 20W.
, which also clocks down to 1GHz in Battery Mode with a 0.95V core has a TDP of 13.1W.
Those expecting to pop in a Core 2 Duo Merom processor to alleviate
an overheating MacBook Pro
, look not here. Merom is a better performing processor than Yonah, but its thermals on paper show its advantages are only in performance and not in thermals at all.
Intel will counter these poor thermals with more "Low Voltage" and "Ultra Low Voltage" processors. Just a few weeks ago, Intel announced an Ultra-Low Voltage (ULV)
processor running on
a TDP of just 9W
. Intel's newest roadmap includes the U7500, an ultra-low voltage version of Merom. However, given the fact that the normal voltage Yonahs have a lower TDP than the average
processor, we'd be hard pressed to think U7500 could possibly run cooler than its

Sorry but you’re comparing apple to oranges, like it was said before the CPU are quite different in terms of performance per watt, hence if you want to speak of the best notebook CPU you have to take the performance of each of them into account.
The fact you say “All Core 2 Duo Merom processors have a TDP of 34W, including the lowly 1.66GHz T5500.”, should be a good reason to not come up with conclusion based on the TDP only, this cause the 1.66GHz T5500 probably wont use as much power as the 2.33GHz T7600.
The Anandtech article about the two also states on the conclusion “Overall, Merom may not be as big of an upgrade to Yonah as Conroe was to NetBurst, but the bottom line is that you get equal or better performance in every test without increasing cost or decreasing battery life.”

Also the Merom can doe stuff that the Core Duo can't do. For example with Lightwave 3d 9.0, I can't run Core Duo Notebook in 64 bit more - but I can with Merom. Yes the uses for 64 bit are limited now - but it is something that the Core Duo can't do.
Also the Merom is based on Core 2 technology and Core 2 technology SSE instructions can execute in 1 clock cycle. So applications that use it will be much faster.
