Raptor Lake HX Mobile Thread

OK, 35818 without any attempt to tune things for this power level, so assuming that 13980HX is roughly equivalent to 13900K at 200W and can hold it, 36k should indeed be within reach.

Excellent, will you also get the liquid propulsion package?

 

 

Only air for now. They are still waiting on the shipment of water coolers.

Fun facts, but what you'll think happens with the Cpu clock speed when Dynamic boost kick in on the other side of the coin and let the 4090 get back it's cooling capacity? The extra cooling headroom from the 150W+ Gpu will clearly help to cool the Cpu in Cpu only tasks. But start streaming (more and more popular), run other tasks in the backround while you gaming ... Probably great fun following the Cpu flutctations (clocks jump up and down as a Yo-Yo) on the screen even if you put an fixed clock ratio. 

 

Me when I looking at the cpu clocking up and down as a Yo-Yo due the GPU steal the thermal/power headroom..... Me don't want that.

 

Me prefer own cooling for both Cpu and GPU. And big enough PSU to feed the needed power for both the Cpu and Gpu. Not this Dynamic boost/Speedshift feature meant to cut costs/make laptops as Apple clones.

I prefer a unified heat sink for laptops. This can then be combined with user adjustable power limits for the GPU and CPU.

As for your system a combined 700+ Watt for CPU and GPU is probably a tad unrealistic in a laptop 😉

 

A realistic goal would be 350 to 400W air cooled and as an add-on 450 to 550W water cooled. Offer that in a 4 to 4.5kg chassis and many people would go for it as they seek the best of the best in a laptop.

Thnaks for trying that - quite a difference in temps and fan noise 🙂 77°C and barely audible vs roaring fans and close to 100°C on the laptop - one can only do so much with so little volume...

 

In my tests I have found that on a laptop one can easily go 10% higher with a unlocked CPU when one only has to complete a single run vs. even a 10min. run. Over 10 minutes sustained power will rear its ugly head and usually it will turn out that most laptops can only sustain something between 80 and 125W of CPU power over a longer time period and even less with non-deafening fan noise.

7745HX (8c). If we double score for the 16c model it would get around 37k. i9 13980HX has some competition coming

Saw that, too - looks promising and that was apparently without overclocking so it would be around 37K stock and not just for an exceptional outlier. That is if TDP does really scale to double what the 7745 gets which I am not sure about but still this will be a chance to get 35K+ CR23 without blowing 200W on the CPU alone.

 

Too bad that these 16 core CPUs will probably not come with Thunderbolt support that I would currently still need for 10G network speed.

 

Edit: Just saw that the 7745 needed 95W for that score so it would be 190W for double the number of cores with everything else being the same - that would not really be that much better than the current top of the line Intel chips and with a lower single core performance.

As I suspected, the 16-core top dawg from AMD isn't going to destroy i9 13980HX

I find GB to be a bit of an insult to geeks. It's very short, therefore the results are quite noisy and thus somewhat unreliable. Otherwise, always good to see AMD breathing down Intel's neck, and pushing them to do more hardcore work for us :)
