3xxx in Laptops

Recommended Posts

Posted · Original PosterOP

Would really love to hear more on how the new 3xxx series would effect gaming laptops. As a student thats the style of computing I go down and would love to hear some theories on how this is going to be shoe horned into a laptop.


Am aware its maybe not a popular choice but in some use cases its the best route.

Hopefully it's nothing like the 20 series. Seriously, there were like 8 independent SKUs of the 2070 for mobile.

 

Pascal was the game changer so don't expect anything revolutionary, ever since 10 series we've basically had desktop performance on the go.


I WILL find your ITX build thread, and I WILL recommend the SIlverstone Sugo SG13B

 

Primary PC:

i7 8086k (won) - EVGA Z370 Classified K - G.Kill Trident Z RGB - Force MP500 - Jedi Order Titan Xp - Hyper 212 Black (with RGB Riing flair) - EVGA G2 650W - Black and green theme, Razer branwashed me.

Draws 400 watts under max load, for reference.

 

Linux Proliant ML150 G6:

Dual Xeon X5560 - 24GB ECC DDR3 - GTX 750 TI - old Seagate 1.5TB HDD - Dark moded Ubuntu (and Win7, cuz why not)

 

How many watts do I need? Seasonic Focus threadUserbenchmark (Et al.) is trash explained, PSU misconceptions, protections explainedgroup reg is bad

As always, you'll get the cards and then you'll get different cooling solutions which can make the performance drop a grade or two.

Still, '1.9' performance/Watt means nearly twice the performance with the same cooling.

That's not true.

 

It depends on what mobile GPU we're talking about but the limiting factor of how well a desktop GPU can be incorporated into a mobile package (AKA the notebook) is its power draw and the notebook's cooling solution.

 

For example: 

1070: 150 W

2070: 185 W

3070: 220 W

 

We can anticipate that, because Ampere requires more power, it will be more challenging for notebooks to effectively provide that power and manage the resultant heat. While cooling solutions are getting better and power bricks more efficient, notebooks are getting smaller as well.

Absolutely, notebooks will see an improvement but my best guess (take it with a grain of salt) is that Ampere cards will see a greater difference in performance between mobile and desktop variants than what we saw with Turing. Probably about a 15-30% loss of performance due to the increased power draw which will cause the cards to throttle. This will also be dependent on the notebook manufacturer's cooling solution.


I should be writing papers...

I 100% get where you are coming from but I cant say its a whole grade or 2 below. (Depends on what you see as a grade) plus 3xxx is supposed to be a more efficient card. Would just love to hear some expert like linus talk about it.
