power consumption P750DM/P751DM?

Hi, i would like to buy a new clevo P750Dm or P751DM with a cpu i7-6700T and a GPU GTX970M. there aren't informations about this configuration and its battery life on the web. what do you think? what are power consumptions in idle mode? in wifi mode (surfing on the web)?

 

idle power consumption shouldnt differ much in various configurations, only load consumption. and putting load onto gpu / cpu while on battery isnt recommended anyways, unless u want to burn through it as fast as possible

 

i just found a review about a XMG U506 (clevo P751DM) with i5-6600K ang GTX980M with a battery life of 3 hours and 30 minutes.

but typical consumption for i7-6700t is about 28.44w and for i5-6600k is about 73.94w

Intel Core i5-6600K Intel Core i7-6700K
Idle without IGP 3.82W 3.46W
Idle with IGP 5.96W 5.62W
Gaming without IGP 52.17W 75.89W
Gaming with IGP 69.26W 83.42W
Torture with IGP 73.13W 100.35W

 

yes in idle i7-6700k and i5-6600k have just the same power consumption 3.82/3.46w.
so it's not a good idea use this laptop in gaming sessions only with battery? but do you use it for surfing on the web only with battery or not?

 

independent from the configuration, u can expect about 1-1.5 hours of gaming on battery and absolute max. of 3 hours for surfing / office stuff.

aside from the unnecessary stress on the battery, ull also have to live with a significant reduction in performance on battery. both cpu and gpu and downclocked in order to preserve the battery. tbh, i really wouldnt recommend gaming on battery, its just not worth it...

 

thanks! i would like to use it in mobility only for surfing on the web and for office apps when i am at the university and 3 hours is great for me!! i don't use laptop for gaming! in many workstations ( as dell 7710 or hp zbook g3) there is an i7-6700hq with a nvidia quadro m3000m. m3000m is certificated for the use with 3Dcad software and it has a TDP of 75W (GTX970m TDP100W). do you know if its power consumption is less than gtx970m?

 

My laptop (Clevo P770ZM) consume about 230w of power.

Spec :
Xeon E3 - 1231v3
GTX980m
24gb ram

 

but i think that 230w is the power consumption at full load. in idle? or at medium load?

 

Full load and zero Overclock.

 

Similar, but you can get the desktop CPU models with quadro cards too.

 

Full load. During idle, it consume about 55w.

 

Skylake models are significantly better. In the 20-30W range. Hardly comparable to the Haswell gen.

As far as idle power, the different GPUs do actually have varying idle power consumption. The 970M and 980M are pretty close, but the 965M using the newer GM206 core is actually much better. The 965M is a rare option on the P700 series though.

 

yes but gtx965m has a 128bit bus, m3000m has a 256bit bus. amd gpu card power consimption are better?

 

Wow i am impressed. What about the battery life? Does lower power consumption of cpu improve the battery life as well? (My haswell P770zm last about 2 ~ 2:30 hours.)

 

Yes the battery life is improved, take the watt hour of the battery and divide it by the consumption to get an idea of what battery life you can get out of it.

 

20-30W on idle with a 82Wh battery would translate into 2.7-4.1 hours battery life. so roughly 3.5 hours on average, about 30-60min more than with the haswell ZM series...

I meant only from a power consumption perspective. AMD power consumption is a disaster and Polaris is underwhelming from a power consumption perspective. Their die shrink to 14nm basically only brought them on par with the Maxwell 28nm architecture. As far as laptops are concerned, NV are still an entire generation ahead.

I get around 3.5 hours of movie time out of my P750DM. I'm rarely too far away from a power point though.

 

i would like to mount a m3000m, in this case power consumption is similar to gtx980m?

 

The M3000M is rated at 75W TDP so it's more comparable to a 970M. So expect similar power figures to mine (3-3.5 hours movies, maybe 4 hours dead idle on minimum brightness, regular use around 2.5 hours ).

The M3000M is very similar in core config to the old GTX 965Mv1 (not the GM206 965M "Ti") but interestingly retains the full 64 ROPs in the full GM204 (980m, 980 desktop). I assume this helps in CAD apps to render multiple windows simultaneously in some way.

 

The quadro cards are usually a bit less efficenct than the desktop cards as they are more concerned with driver stability and CAD applications.

 

m3000m have the same chip of gtx980m, so the next generation of quadro will be based on the same chip of gtx1080m?

 

Quadros kind of follow their own schedule usually.

 

for example in october 2014 nvidia released gtx980m, in august 2015 nvidia relesed m3000m. new gtx1080m will be released on september so next generation of quadro will be released, probably, one year later. I should wait?

 

If your work absolutely needs a Quadro , then yeah.
Or get a system with a Low end card right and upgrade only the GPU next year.

 

M3000M is not the same as a 980m. Yes, it's a GM204 core but a significant number of shaders and TMUs are cut out of it. A more apt comparison is that the M5000M and 980M are indeed identical.

It's worth noting that most major CAD packages have changed to Direct3D, removing the need for true Quadro cards and their OpenGL multi-window acceleration. In which case you're really only wasting money. On the flipside, if you're on a CAD package which doesn't use Direct3D, the money you save getting a GeForce card will probably pay for new CAD software anyway.

 

Ah didnt know this. Haven't followed CAD development for a long ass time.

 

solidworks recommend quadro and firepro but i don't know if it uses opengl or directx. autocad and inventos require directx 11. autodsek cfd simulation requires opengl rhinos requires gpu compatible with opengl2. so this is a problem!!

 

Usually the bigger packages have their own forums so you can ask on there the kind of differences you will expect between the different GPUs.
