Merom reported as a power hungry little heater

Some quotes from this article: "Merom" runs hot, "Yonah" might be the better chip for notebooks."

And, "The top of the line Yonah processor, the T2700, has a TDP of 31W at 2.33GHz clock frequency. All Core 2 Duo Merom processors have a TDP of 34W, including the lowly 1.66GHz T5500. In comparison, the 1.66GHz Yonah rings in at 27W."

What do you think the practical impact will be on the Thinkpad line. That battery number is still a TDP 20W; what do the engineers, think?

where is that article? Tomshardware reported the opposite I must add. Moreover, 34 Watt TDP is not high for a 64 bit dual core mobile chip. And here is the quote from Tomshardware benchmark test (The test considered The T7600 (merom) clocked at 2.33 GHz, The T2600 (yonah) at 2.16 GHz.
)

From the tone of the article you mentioned, I am guessing that it is from AMD tuned theinq.

 

Lower voltage will rectify that , tho some power loss

Core 3 duo will be the real fix next year ... skip core 2 duo it's just stop-gap for xmas

 

lolz.. SkiBunny.. GooD Point..

 

You're right though, it does sound a little like the inq in its tone, but its from DailyTech and I don't know which (if any) way they lean.

 

I discovered a few weeks ago that my engineering sample T7400 ran at least 10C hotter than my Duo. This was at idle. I tested again yesterday after updating my M1210 to the latest BIOS. Just idling Merom would heat up and cause the fan to turn on every few minutes (had Fangui set to turn on the fan at 55C). My 1.83GHz Yonah would not heat up much past 40C so the fan never turned on. As far as battery life is concerned I lost about 15 mins using Merom.

I'm not exactly sure why everyone is surprised that Merom runs hotter and may use more power. The CPU has millions more transistors than Yonah. More transistors means more power usage. More power means more heat.

 

because of the persuasive power of the intel marketing machine ? LOL

 

probably not as simple as that now that intel has figured out how to turn off parts of the cpu. 50 Transistors on for 50% of the time definitely consumes more power than 80 Transistors on for 30% of the time. But we really don't need a discussion on this because it gets pretty technical.
