On my laptop (Core i7-4800MQ), Prime95 will cause the processor to hit 60 W power at around 2.8-2.9 GHz for around 15 seconds, before settling down to 47 W at 2.7 GHz.

Bob

@noitsbecky Firmware-based limit, yea?

bwDraco

AVX-rich code can cause the CPU temperature to go through the roof.

noitsbecky

@Bob Probably, since it applies in both Mac OS and Windows.

Journeyman Geek

12:51 AM

@bwDraco but asking him IF it overheats...

noitsbecky

Ironically, they've supplied an 87w power adapter and set the processor TDP to 100w...

Journeyman Geek

@bwDraco @noitsbecky can and will probably look at the transcript ;p

bwDraco

@noitsbecky lol

Journeyman Geek

@noitsbecky so, it'll basically drain the battery if you somehow turn the processor up to 11?

Bob

@noitsbecky Fairly typical for gaming laptops, no?

noitsbecky

12:52 AM

So in reality they've reprogrammed it so instead of TDP throttling it thermal throttles or the whole system power throttles

@Bob Most gaming laptops have 45w processors with TDP set to 45w... only rarely do you see the unlocked ones overclocked, but Apple's managed to remove the TDP on non-unlocked CPUs

bwDraco

@noitsbecky As far as I can tell, Apple uses its own chipsets and are not bound to the limitations of the HM170 or other similar PCH.

Bob

@noitsbecky + GPU

I remember a few gaming laptops that'll drain the battery on full power.

Fairly rare, though.

bwDraco

@JourneymanGeek On battery, my laptop will throttle to 1.6 GHz on battery, but that can be overridden using ThrottleStop. However, I cannot override the GPU throttling, nor can I cause the CPU to run at a higher TDP.

178

A: Why are my games slower on battery power, even with the power plan set to High Performance?

Running a high-performance GPU at full speed while on battery can damage the battery or require more power than the battery can safely supply High-performance mobile GPUs can require significant amounts of power to operate at full speed. The GTX 765M requires 75 W, while top-of-the-line mobile ...

Journeyman Geek

@bwDraco its apple though

Bob

@noitsbecky Wait, sorry. I meant fairly typical for the power adapter to provide less power than the laptop can use on max. Not that it's typical to increase TDP limits like that :P

@noitsbecky As far as I can tell, Apple uses its own chipsets and are not bound to the limitations of the HM170 or other similar PCH.

Journeyman Geek

They probably design their own motherboards from scratch, and as a marquee client they have the freedom to ask intel for strange things

noitsbecky

2:06 AM

@Bob Oh. On gaming laptops, not really so common anymore

Usually they'll overprovision the power supply, now that higher power supplies are fairly common, efficient, and cheap

There's laptops that come with dual 300w power supplies... but mine uses up to 200w-ish peak (120w GPU + 45w CPU) but comes with a 240w supply for example.

It's more low-end machines, ultraportables and tablets that come with paltry 30-45w supplies that are less than the laptop can use at full tilt

bwDraco

My laptop is actually rather tight in this regard. The supplied AC adapter is 180W, but it gets run up to capacity (and in fact, slightly beyond capacity) if I overclock the GPU and/or max out both the CPU and GPU.

Bob

@noitsbecky Yea... I think I just remember it from when laptop adapters were maybe 120W max. 90W more common.

bwDraco

My old laptop had a 90W adapter but never pulled more than 75W under load.

bwDraco

...and I might just look into getting a 4K display.

One 4K display, one 1440p?

Journeyman Geek

That's not uncommon

bwDraco

1440p probably makes more sense for gaming. I'm not too sure I'd really benefit meaningfully from 4K...

Journeyman Geek

That's up to you

bwDraco

We'll see when the budget is determined. How well I behave IRL will play a major role here.

(that said, I've greatly improved my ability to stay calm even under less-than-ideal conditions)

Regardless, my main desktop setup must have at least two monitors.

I can always reuse my cheapie Acer 1080p IPS display, but I'd prefer a pair of 1440p IPS gaming monitors with G-SYNC. (sorry AMD, I'm probably not going to get a Radeon, though I am strongly considering Ryzen)

After all...

Hmm... I do wonder if I can build PhantomJS somewhat more intelligently than they've done. They built a "static" executable that links in Qt and stuff but then dynamically loads system OpenSSL, lzma, zlib, libstdc++, libpng, libjpeg, libxml2, libfreetype, libfontconfig, etc.

Might be how Qt is configured to depend on those at runtime instead of at build time

It might be a fatally flawed approach they took, because they seem to compile in glibc, but then the system libs you have to provide also link against glibc but possibly an incompatible version

Works fine for the distro it's built for but not portable really at all

Could link it totally dynamically and ship all the shared libraries needed, or statically link the world and hope I don't miss anything, but this middle of the road approach with some system dependencies isn't portable to other distros and especially to older systems - even though the kernel ABI has been frozen for a very very long time

Burgi

2:04 PM

would that question be better suited to arqade or here?

Journeyman Geek

I'm not really sure its answerable, since the steam hardware survey does not mention browsers at all/

Either that or they've typo'd windows 10 into Edge. But either way they say nothing about Windows 10 users all using edge.

@Burgi it doesn't. Steam hardware survey is... a hardware survey.

@Burgi makes no sense

Nothing to stop it reading default browser info and it probably does as part of it's diagnostics but since the browser isn't hardware...

@noitsbecky you might run away when you experience local connectivity :P

Burgi

noitsbecky

@Bob lol.

Tbh the way you make it sound doesn't seem much worse than London, and most busy cities in the UK are pretty crap.

I'm just lucky as somehow Edinburgh always comes top or near top for mobile and fixed line speeds for the UK, and is on average nearly 50% faster than average.

(also I rarely get more than 60Mbps on the 420Mbps LTE-A masts unless at 4am)

Bob

@noitsbecky Eh, depends if you want wired or wireless (LTE), I guess. And what London gets :P

@noitsbecky Funny that we supposedly have one of the more advanced LTE setups tech-wise, but you routinely get speeds I never see even in the best conditions -_-

noitsbecky

@Bob 3Mbps average on 3G. About 10Mbps on 4G?

Bob

@noitsbecky Oh. Dunno about 3G but you'll probably get that on 4G most of the time.

Worst I've seen (poor coverage indoors) would be 4-5Mbps, 7Mbps maybe, up to 15-20 if you twiddle it.

noitsbecky

2:45 PM

@Bob that's part of what I'm curious about, I want to see the network conditions first hand and figure out how it can really be that bad

Bob

@noitsbecky idk, I've tested with an S7E (Exynos) and Xperia X Perf (S820), flagships with supposedly the best connectivity with global band support

noitsbecky

I twiddle a lot. Twiddling is my life.

@Bob maybe it's just Fox paws don't conduct signal as well as cat paws

so I don't think it's anything on my end

noitsbecky

Maybe like most people you don't instinctively and reflexively twiddle 24/7

Bob

lol

Oh, also the $/GB

noitsbecky

2:48 PM

I mean I have real time feedback on network throughput and signal etc. so when I do a speed test I don't just hold still like most people but automatically just twiddle to get the best throughput.

Bob

btw @JourneymanGeek @allquixotic the Amazon reship arrived. so I now have 32TB more space...

more than double!

noitsbecky

After all my >280Mbps records have all been me outside in the dark waving my phone around for literally hours doing test after test while moving a few millimetres to the left, then the right, etc.

If I just walked along the street and did a normal test I'd have a 1-in-4 chance of getting over 200 and mostly get 100-150

Bob

@noitsbecky I did multiple tests while spinning around -_-

noitsbecky

@Bob one does not simply spin their way to LTE-A peak speeds

Journeyman Geek

@Bob noice ;p

What Programming Languages Are Used Most on Weekends?

Julia Silge on February 7, 2017

For me, the weekends are mostly about spending time with my family, reading for leisure, and working on the open-source projects I am involved in. These weekend projects overlap with the work that I do in my day job here at Stack Overflow, but are not exactly the same. Many developers tinker with side projects for learning or career development (or just for fun!) and at Stack Overflow, we support all types of technologies, from professional to hobbyist. Whenever people are working, we're available to answer their questions. But what languages tend to be asked about on weekends, as opposed to weekdays?
