Talking about TDP (Thermal Design Power) of the GPUs

[sicily428]

Hi! I think we should make a guide about TDP (Thermal Design Power) of the GPUs.

I'm watching so many people asking for thin and light laptops with a powerfull hardware (gtx1070/gtx1080) but they don't know consequences for that. A powerful gpu needs a good cooling system and there isn't enough space for it in a thin laptop. Thermal issues are really important for a thin laptop with a powerful hardware and thermal throttling can easily increase with a drop in performances,

 

here a cooling system

 

 

and here an heat pipe

 

 

What are values for each Nvidia / Amd gpu? where can I find right values for that?

 

 

______________________________________________Laptop_____________________________________

these should be standard values of TDP, but each OEM can use different values :

 

Nvidia

gtx1050  ------>75W

gtx1050ti -----> 75W

https://www.techpowerup.com/gpudb/2912/geforce-gtx-1050-ti-mobile

 

 

gtx1060 ------> 80W/85W

https://www.techpowerup.com/gpudb/2868/geforce-gtx-1060-mobile

 

 

gtx1070 ------> 115W/120W

https://www.techpowerup.com/gpudb/2869/geforce-gtx-1070-mobile

 

 

gtx1080 ------> 150W

https://www.techpowerup.com/gpudb/2870/geforce-gtx-1080-mobile

 

 

Max-Q Nvidia Gpus

Max-Q gtx1060 ------> 60W/70W

 

Max-Q gtx1070 ------> 80W/90W

 

Max-Q gtx1080 ------> 90W/110W

 

AMD

RX580 ------>????

I've found gpuboss.com to be a fairly reliable source for getting general info about graphics cards. The RX580 has a 185 watt TDP by the way.

There will always be a race for thin and powerful performance from consumers to the manufacturers. Well, only time will tell how it will turn out . And, that's what this forum is here for, to let them know what's technically right

forum like this are really useful for customers. OEMs are not so accurate to inform about performances of their systems.

Keep in mind that many of the thin laptops that feature powerful GPUs often use Max-Q versions.

 

They’re less powerful compared to the standard variants.

max-q are:

gtx1060 max-q (Nvidia should call it gtx1055)

gtx1070 max-q (Nvidia should call it gtx1065 )

gtx1080 max-q (Nvidia should call it gtx1075 )

 

do you know their TDPs?

Pretty sure my tuned 1070 outperforms a max q.

is that an OCed gtx1070?

IMO those max-q are:

gtx1060 max-q----------> gtx1055 

gtx1070 max-q----------> gtx1065 

gtx1080 max-q----------> gtx1075

Those variants don't exist. MAX-Q variants are the same as the regular ones, just clocked slower. The GTX 1080 MAX-Q version runs at 1290-1468MHz, vs 1602-1733MHz of the regular one.

 

Assuming the MAX-Q GPUs are not undervolted too, you could take the percentage difference of the clock speed and apply that to the TDP since there's a linear relationship between TDP and clock speed.

At stock speeds on either, they're about the same.

I call those underclocked Max-qs with these names: gtx1055, gtx1065, gtx1075. That max-q name is a Nvidia's gimmick for selling pricey underclocked gpus to unconscious customers

I find not using common lexicon worse than whatever the manufacturer says. If the manufacturer wants to call a chicken a pig, then it's going to be called a pig. Calling it anything else is going to confuse people who don't know better.

Infact I wrote this:

However your lexicon is not common lexicon. You're only going to confuse people with this.

They have a table.

If you look at GPU-Z load power consumption figures (I know they're not reliable), most are down about 40% from the desktop equivalents.

It's pretty depressing actually. Based on my experience, once you load these things up they start throttling in minutes. Some designs are really marginal as the small cooler is shared by the CPU and the GPU. Loading the CPU alone or the GPU alone would typically be fine, but everything goes haywire once both components get fully loaded.

 

Frame rates are awesome for the first 5 to 10 minutes of gameplay, then things start stuttering. This is why undervolting is a thing for this kind of machines. Frame rate limiting can also help as it lowers the load on both the CPU and the GPU.

I think there is a seriuos problem with marketing gimmicks. OEMs need to sell more laptops and to save more moneys. so they use soldered components (cpu, gpu, now also rams) and they don't care enough about the cooling design, reliability or construction quality. People ask thin and light and OEMs offer those

I'm trying to say: if a customer needs a gtx1070, he should buy a thick laptop with a good cooling system but OEMs offer thin and with overheat issues laptops

Absolutely. This is marketing-driven for sure (I don't see the engineering team championing this idea).

 

Thin and light designs sell + Impressive spec sheets sell = What we have now

Well u can't overvolted mobile GPUs cept for mxm custom bios laptops. 

 

So undervolting is the only option.

I still feel that a GTX 1060 is the sweet spot for a laptop

I'd want something like an aorus X5 Md with a mux and the 1080 with an unlimited voltage and wattage draw and lemme decide how to cool the thing. Binned 1080s only so max undervolt and Vapor chamber cooling system.

At the typical 15" form factor, that's about as high as I'd go as well (unless it's gonna be a thick laptop).

 

Expecting these two tiny blowers and little fins to cool an i7-7700HQ and a GTX 1080 is asking for too much:

So you want to blow up your GTX 1080?
