Penryn vs. Merom Heat Output

On startup, just idling, what temperature is your processor?

Give temp in Celsius and give the model number for your processor.

I have a T7700 and it idles at 45 C.

Just to clarify, I'm talking about when you have NOT been using your laptop at all. When you first start it up, and when it's idling, that's the temperature I am interested in.

 

Penryn is the 45-nanometer technology platform. One of its key features is cooler operating than the Merom Platform.

 

T7300 idles around 45C. Load is somewhere in the 60s.

And yes, Penryn chips should be significantly cooler than Merom chips, though I don't know by how much.

 

Duh..? I already know this. I'm just curious how much cooler it actually is.

 

I'd like to know as well; my T7100 idles at 40C.

 

I'm going to have a T7500 and a T9300 side by side in a couple of weeks probably, I'll try some identical tests on both.

 

i will post up my temp. tonight.

 

T9300 2.5
Idles at 41C.

 

Posting your temperatures in this type of scenario doesn't means a lot..... what is the temp of the air surrounding the laptop? have you been using it at all lately or has it been sitting idle for a long enough time to actually reach a stable temp? how many apps do you have running in the background? idle never really means idle.

and so on.

 

I'm talking about when you haven't used it for like an hour and when you first turn it on, what the startup temp is.

 

T7500 at 38 C idle, with a little bit of undervolting.

 

unless the temps are going to be measured from a controlled place, this is pointless, since everyones ambient temps will be different

 

The all of our ambient temps need to be controlled is partially true and partially untrue.

If we were compare an individual processor temp sample with another individual processor temp sample, we would need to know the ambient temp to create a good comparison.

However, if we gather a large sample of various processor temps operating at various ambient temps and take an average of Meroms and Penryns, we can still get a good idea of the average operating temps of the two types of processors.

Even if the average ambient temp of the entire sample is not representative of the true average ambient temp at which these processors operate, we can still get a good measure of the difference in average processor temps, given these average ambient temps.

Or something like that.

 

lol, i understand what your trying to say Wolf, but you made it sound quite confusing then its not suppose to be

i only stated that simply cause ive done alot of testing on desktops with various
air and watercooling to get an average for myself when comparing temps with other people

Also im sure like desktop cpu's, some do tend to run cooler then others even under the same load and ambient, so it will simply be more helpful if people were able to post their temps along with ambients

 

Obviously these aren't meant to be pinpoint accurate tests. I was just curious to see roughly what temperatures people were getting.

 

T9300 after booting up idles at 33 C consistently never goes higher.

 

T7800 idles at 33C, maximum 73C.

 

that's amazing compared to my amd TL-50 idling with a zalman at around 52 C

 

my t9300 idles @ 26c loads @ 60C

 

Is this with or without fans coming on?

 

T7500 idles at 31C, maximum 65C.

I see no real need for the Penryn yet.
Very marginal difference is temps and battery times.

 

how do you all achieve such low idle temp for T7500? are you guys undervolting the cpu? mine idles at around 46C, and that is the lowest i can achieve with stock voltage.

 

without the fans reaching hearing speed

 

For those of you that have both types of processors, does the machine feel cooler with the Penryn processor; can you actually tell the difference if you touch the machine?

 

This is pointless, until someone tests a merom machine then pulls the cpu out, replaces it with a penryn and does the test again (same ambient temp, same machine, same os, same load condition, same fan setting... just different cpu).
