If you can figure out what that means for 3x3 vs 2x2 or MU-MIMO, you're doing better than me everything else I can find caps out at 2x2 wave2 (Intel 9560 or Killer AC1550)

I'm shopping for a new laptop, to replace the device I wrote my PhD thesis on, this Asus P53 that I've had for more than 6 years. My computer needs to be a competent workhorse, not a high-performance elite machine. My priorities are long battery life, at least 3 USB ports, and being neither enormous nor ultralite - about 15 inches for the screen seems right. My budget is $1200 Canadian. My stupid questions are, what's the deal with the i7 / i5 / i3 Intel processors? Is bigger number = better? Is the i-number more or less important than the number of cores?

The i-number is marketing bullshit and means nothing except within a given generation and wattage class, in which case it can mean any of a number of different things. Like, just looking at 8th generation to keep ourselves from going nuts, i5 can mean: a slow 15W mobile quad-core with HT a slightly faster 28W mobile quad-core with HT and an upgraded IGP a slightly faster 65W mobile/SFF quad-core with HT and a Vega IGP a midrange 35W mobile quad-core with HT (and a normal IGP) a slow 65W desktop six-core without HT a faster 95W desktop six-core without HT that can overclock Look the specs up for whatever chips you are considering on ark.intel.com and use the comparison tool if you want to actually know what's going on.

I don't think paying extra for the i7 was ever worth it. Especially now since the i5 are also quad core.

The number is not important, look at the number of cores and boost clock if you want to compare them. Even then it can be misleading, for example the pre-8th gen i5s and i7s behaved pretty much the same in most laptops since thermals are usually the limiting factor.

Not only are they meaningless now but processor designations have been largely marketing bullshit since 15 years ago when Intel put out a new series with much higher clock speeds but much lower performance per clock (Pentium 4) and AMD said "we'll just label Athlon XP with a 'performance rating' that coincidentally looks like a clock speed number but totally isn't, since we can't compete on sheer clocks". I don't really know what the alternative would be at this point, considering that with multicore processors clock speed itself ceased to be a clear indicator of performance even within an architecture. You have to look at the spec sheet if you want to know what you're getting.

There's no use case. It's literally an end user dick-waving about not getting the theoretical speeds of wifi devices. That said, Netgear makes a USB adapter, "Nighthawk AC1900" model A7000, and I have to say it's not worth it. The built-in 2x2 802.11ac wifi built into my laptop performs 90% as well as the Netgear USB adapter, and the driver for the USB adapter is not very stable.

Why does my stupid laptop run its stupid fans all day long? I bought a Helios 300 a couple months back when it was on sale on Amazon and its so loud with its fans. According to the program that came with it, its always around 70 C, which is pretty hot but it doesn't feel hot. It's a pretty new computer, what's the deal here?

That's pretty hot, and if that's with the fans blowing then it'd be a lot hotter without them. Laptops have a bunch of heat-generating components in a very tight space (especially gaming ones with a discrete GPU). If you're not really doing a lot, the CPU running easy with discrete graphics, it won't put out a lot of heat and the fan might not run at all, or very quietly - it depends on the ambient temperature in the room too. But start to do anything more demanding and it'll need to start actively cooling the components You can do a few things - make sure there's good airflow (maybe raising the laptop off the desk or whatever), undervolt it, or mess with the cooling policy so the fans kick in later. But when it starts to get actually hot, those fans need to come on, and if you're gaming then they're gonna crank up

There's no reason it should sit at 70c constantly. You either have some background task consuming a lot of CPU, or there's something wrong with your cooling. Check software first, then repaste it if it's not under warranty.

The Razer Blade 15 looks pretty badass. It fixes most if not all of my complaints about the 14. One thing though: why haven't laptop manufacturers adopted 1440p? It's the perfect resolution for the screen size. 1080 is OK but pixelated, 4k is overkill for a 15" screen and you can't push over 60hz easily. 1440p at 144hz would be the perfect resolution for a gaming laptop with a GPU such as a 1070.

Windows scaling works like 99% of the time at this point, it's really nothing to be afraid of unless you're an IT grognard who has to deal with supporting ancient applications, in which case get a thinkpad.

Otherwise, I'm generally fine with having a higher resolution and scaling when necessary, although I'm sure power draw in laptops is a concern with the higher-res displays.

Laptop fan noise is often pet hair clogging up the airflow If out of warranty, take it apart and pull out the dust and pet hair Also yeah there's a non zero chance you're mining bitcoins for the Russians.

Atomizer posted:This, add an m.2 SSD and as much RAM as you'd like. I would prefer Windows 10 Pro over Home if possible, unless they're not actually different in a meaningful way. I plan to run all sorts of random, old, low-user-count programs on this computer, and basically use it as the computer of last resort for every application of my lab group. I'm a scientist, I need a machine that will spend most of its time running Microsoft Office stuff and R Studio, but sometimes will need to run the gas analyser or automatically log output from the precision balance. I *think* all of those old weird scientific-instrument programs are going to run just fine on anything made since 1998, but if Win 10 Home has an over-protective nanny mode that won't let me install this poo poo I need to avoid it or know how to turn that nanny mode off (actually off, not just the "OK! I'll only bug you EVERY TIME" that Windows Vista does). Also, what would be the advantage of adding a 250GB SSD? I know SSD means much faster access compared to a spinning disk, but is permanent-storage access a limiting factor for most programs running smoothly? I do use my computer for photo editing, and loading 16GB RAW files can take a bit of time but speeding that up doesn't seem to be worth the hassle of maintaining a file structure more complex than C:\Photos. Is there another, more general advantage of an SSD I'm missing?

ExecuDork posted:This looks pretty good, thank you! I recommend checking the comparison chart for Pro vs. Home, but if you decide you have to have Pro then getting keys aftermarket is pretty cheap. Most programs at least have a substantial improvement in startup time with an SSD and some perform way better during use as well; you should definitely give it a try if you haven't had one before now. You don't need to maintain a complex file structure, just install the OS and any programs you want to on the SSD as C: and any HDD you add in will have a separate drive letter by default or can be mapped to a folder instead.

Acer's coming out with a higher-end Helios 500 and a refreshed 300. The 500 isn't that interesting as it's going to be a higher-priced entry, albeit with high-end features, but the new 300 is mainly upgraded with a 144 Hz display (and more storage) with the rest of the specs appearing to remain the same. Hopefully the price will be close to $1k as that's what made it notable.ExecuDork posted:This looks pretty good, thank you! If you don't know the feature differences in Pro over Home then you probably don't need the former. I mean it's a possibility but I'd say it's more than likely you'll be fine with Home. Even then I'm sure you can still find $5-10 Pro keys on eBay; look for the ones from UK sellers that say they ship with a broken mobo (they won't bother shipping anything of course.) You absolutely, 100% want any OS to run off of solid-state storage. This means any SSD for a PC, and of course things like tablets and phones have eMMC at least. You will totally notice the difference in performance (due to random access as opposed to continuous data transfer) over an HDD. You can use HDDs for bulk data storage. If anything, a modest SSD (e.g. one of the $30-40 128 GB ones you can find for sale all the time, even one without DRAM which I otherwise wouldn't normally recommend) will definitely give you better OS performance compared to any HDD, whereas a fast HDD would be a wise complement for loading your huge RAW files.

With knee surgery coming up and me being stuck in bed for a while I finally got a laptop of my own. Through a series of constraints I had to get a Dell, so got the new Alienware 15 (8750h, 1070). Since I don't plan on moving it around too much anyway and battery life isnt a concern. It wasnt my first choice if I had the option to get any laptop but I'm kinda liking it. The last laptops Ive touched were some Win8 era machines so the improvements are all really nice. There wasn't even as much bloatware as I expected, though MS itself put a bunch of phone games on here. Think Im gonna play FFXV this summer, since my desktop is rocking an older AMD card that couldnt really run it. Still, the laptop experience is a lot better than I expected. The phone mirroring app is cool too, since it is basically Vysor with bluetooth so it can handle calls. Glad buying PCs isnt the hellscape of garbage software I remember from years ago, even with me buying one of the would-be worst offenders.
