i7 720qm @ 55W?

Noticed something funny today. Perhaps just a bug in HWMonitor. Reinstalled but it was still there:

 

Meh it's likely just guessing.

 

How informative...

Clearly you are aswell

 

Check out my max value for the CPU power draw

 

Ok Intel clearly lied to you. Return the CPU and open a class action lawsuit

Hmz, I wonder which of these is more likely on balance.

 

I'm just trying to find out if :
a) there is a bug in HWmonitor, or
b) the cpu is really drawing 55W

If you can't contribute, why post?

 

IMHO the 720QM is rated at 45W when it's running at 100% load at its nominal speed (1.6GHz). The TurboBoost feature allows the CPU to self-overclock, given a temperature headroom. In such case, the clock rises to 1.73GHz, hence the increased TDP. The 920XM is reported to have maximum TDP of 65W (by the same software, CPUID HWMonitor).

 

The 95w Core 2 Quad in my sig is reported to only use 50-something watts as well. Take HWMonitor's numbers with a grain of salt.

 

You mean years of experience using these sorts of programs and their shoddy guess work on power usage and telling you that its very likely to be guessing.

Ok fine, you carry on taking its word, just dive under the bath tub when it reports a 24KW usage.

 

You could install AIDA 64 and compare the 2

 

When Sandy Bridge was announced Intel said that the ability to go BEYOND TDP was something new to the i7 processors. Are you shure that the 720QM is able to do the same? I thought that the reason why first gen i7 was able to stay at higher turbo frequencies for a much longer time (or forever, i can`t remember) than Sandy Bridge (that falls down after a while) was because they stayed within the TDP aka 45W for 720QM

 

I'm thinking the same. I've seen all core above 2.0GHz at the same time as well. Maybe someone can confirm thiss, or someone else with a 720qm can show the same number.

Still not helpful.

 

Max TDP for a i7 720QM is 45W, see here: Intel® Core? i7-720QM Processor (6M Cache, 1.60 GHz)with SPEC Code(s)SLBLY

HWinfo32 tries to report the power draw of the CPU if I'm not mistaken, that's not the same as the TDP! 55W under load is reasonable I guess, though rather on the higher side probably. Also keep in mind that this number is probably not 100% correct... I don't know the method HWinfo32 uses to calculate this, but there will be some measurement errors involved.

The max TDP of a 920xm is 55W, stock setting of my ES 920xm is 62, according to Throttlestop. The 920xm has an adjustable TDP.

The first gen i7 got you less turbo boost than the sandy bridge cpus. At least that's what I experienced and also gets reported by a lot of people. That's one of the big improvents which the SB chips have... better, longer and higher Turbo Boost.
Turbo Boost doesn't need a higher TDP... the idea about TB is to push your CPU harder when there's still enough thermal headroom.

 

That is partial untrue. If you compare the 820QM to 2820QM you will see that first gen i7s are much better at sustaining turbo boost. Sandy Bridge CPUs have both thermal envelope it follows -and- a timer that effectively limits what speed you get with 2820QM with TB. With 2820QM you will reach 3.4 GHz but it will fall down to 2.7 GHz after a while and stay there according to Anandtech. That is the upper limit of the TDP and not affected by the timer. Everything over is considered above TDP. Users are saying the same. SB throttles a lot.

820QM have Turbo Boost up to 3.1 GHz and if i remember correctly, it does not fall down like SB CPUs does. I could remember wrong but that is what i have heard.

Anyhow, i thought the TDP was the same as power consumption/draw?

 

Lol tbh sounds like if someone pulled you from a cliff you would declare it was not helpful.

 

Heres mine

 

In AIDA I got 46W max. You're temps are pretty high btw

 

Nah there fine.Its was about 81-82F in the house when i did that.

I usually keep it about 68-70F in here but I had just got home from work.

 

Ok, interesting... my experience with the 720QM is that it isn't really generous with Turbo Boost, especially with boosting all 4 cores.


The TDP is the thermal design point, it describes the maximum amount of power which your cooling system of the CPU must be able to handle... Usually that's about the power what real world applications will use, but when doing some intesnse tasks like encoding videos (100% load all the time across all cores) you will see that this doesn't apply anymore, it's pretty sure that the CPU will use more power. But this will lead to thermal throttling after a short while in most cases, as the system runs too hot.

 

Yeah Sandy Bridge is better at turbo boosting 4 cores. I should say that Anandtech did mention that if you have enough thermal room you should get higher TB speed than 2.7 GHz with 2820QM within TDP too, but nobody have confirmed it. That is why i said it was "partial untrue".
Thanks for the description of the TDP. I learn something new every day.
