      1 ) Chromium is the engine that translates basic stuff (HTML, CSS, JS etc) into a working webpage. It contains all the parts you need to run your car. The browsers are simply "extra features" and they often add tricks to either speed up the translation of the above named things (by caching it or trying to predict stuff) and gives the browser creator the ability to inject stuff into the chromium engine -- So, add-ons. With a car this could be bouncers for example. Basically, it allows them to mod the car.
      2 ) Operating systems are just very complicated programs that get started up by a tiny command on what used to be your Master Boot Record, but I guess the UEFI is smart enough to find OS's now. An update is not much different from updating a website or app in the sense that there are certain things you can update while the user is looking at it, and certain things you have to reload the website (restart the OS) for. An update basically just overwrites older files or adds some. It's not that complicated, really...
      3 ) In deep-level programming, the developer can decide what types of commands to send to the CPU. The developer can decide how much memory to allocate, how much stuff to remember, what exactly to remember, etc etc... Intel and AMD cpu's have different ways of handling commands. They are, much like browsers, trying to be "smart". CPU's haven't really gotten much faster in hardware speed (MHZ) as you may have noticed the past 10 years. However, their performance keeps increasing; This is because of what they call the 'architecture', which basically means a tiny software layer which translates stuff into tasks for the CPU. We call this firmware. This, mch like the browsers in point 1, tries to predict stuff. Some CPU's do less but faster cycles (in the old days this was intel) where as some do slower cycles but with more calculations within said cycle (AMD in old days). This means any command has to "wait" until the previous cycle is done, but starting up a new one also costs time. So if you put a lot of calculations in one cycle as the developer, the slow-cycle one might handle it faster as you use the slow cycle to do more calculations. If you do a lot of small calculations instead, the smaller cycle will win because it's faster. ARM is basically a CPU without intelligence, meaning whatever the CPU does has to be software-managed, but it does save a lot of overhead as the CPU doesn't have to "think" before executing what you tell it to execute.
      Now that you've read all this, I have to admit to you that I have no idea what I'm talking about at all and probably not even half of what I said is true.

    Free Tech Tip: If you have connected a lot of stuff (multiple M2 SSDs etc.) to your Mainboard and you want to find out if it hurts your GPU link, fire up GPU-Z and check the "Bus Interface" information. It should say @ x16. If it says @ x 8 then your GPU is sharing lanes with something else. This could be a reason for some performance loss on GPU side.
    You're welcome :)

With Crossfire and SLI being basically dead, 1x16 is more than enough for the vast majority of us graphics wise, although I suspect AMD and Intel will eventually move to 24, 28 or 32 non-southbridge lanes so as to support more NVMe direct to CPU.

    About the mouse you mentioned at the end. I use a Bluetooth mouse with my laptop for the convenience of not needing a dongle but I don't really see much if any latency. It is one of those things most people might not even notice really. I have an HP XB4000 mouse and an Intel AX200NGW that I use for Bluetooth and WiFi. That card can be gotten cheaply but I mainly use it because it is a good one. It is not a tri-band card but it is WiFi 6 and I get a good fast connection 40 or 50 feet away on the other side of the house. This place is not small but a good TP-Link router seems to cover it well and without a horribly slow connection too! This was more about a mouse than anything and quickly expanded into other things.

    Kinda why I went with Threadripper, I love having the PCI-e connectivity, I had the 5960x and while it had 40pcie lanes, it still had some weird routing and slow downs or it disabled something somehow that I needed or could use. This threadripper system I do with the Asus x399 Zenith Extreme would of had the option to turn the x8 slots into x16 so I would have to install my video card the way it is, but I got enough lanes to not slow anything down, especially storage.

      @@sparhawk1228 Yes, and some of them lanes are dedicated to other parts of the system such as onboard wifi ect, i'm not sure how many lanes the chipset has, but it isn't much and can cause delays in some things though mostly irrelevant. I have a ton of high bandwidth pci-e devices where the 5950x would be fine for most of my wants, but I often over time find my self needing or wishing I had more PCI-E lanes. I had trouble with with Intel x99 with its 40 lanes and all of my nvme devices, and how the board was laid out.
      The 5950x would be fine for most users who just want to game with a few pci-e devices.

      Bit pricey for a gamebox though, and probably not as good as the equivalent 3900x for games unless you go for the lower-end 3960x with its higher clock rates. Not to mention that even with boards like the MSI Creator TRX40, only two of the three onboard NVME slots are CPU-side. To get more CPU lanes to NVME drives, you have to use the riser the board comes with, and you have to be particular about which slot on the board it goes in and how it's configured.
      That said, I do enjoy having blink-and-you'll-miss-it load times and not caring how many tabs I have open. CPU video transcoding at ridiculous rates is nice, too. There's definitely advantages to be had from a whole bunch of PCIe lanes and 24 cores. You're just not likely to see them if your use-case is general Internet use and (most) games.

    strangely the "widening of the highway" doesn't really benefit gamers, more production or creative types. I work with a fair amount of raw files.. i notice a difference between my nvme drives despite them being rated equally due to the lane config... if they are on the 500gb (cpu lanes) it's borderline lightning.. other is still much faster than an ssd (i have tried) but markedly slower than the cpu lanes. This is in applications such as Luminar, Lightroom and not as much but still noticeable in photoshop.

    Don't forget Threadripper routes to each half of the CPU. So if you want to run 2 storage devices and get full bandwidth you have to use both halves of the die. I was able to get 15GB/s read by bifurcating the slots on opposite sides of the lanes. Otherwise I'm capped at 9GB/s.

    Considering the normally insanely expensive and high-end stuff Linus deals with in videos, it took me a few moments to realize that's the exact mid-tier motherboard I used in my last build. Was wondering why it looked familiar. Also funny that he pointed out that specific M.2 slot at 3:05 since that one normally has a sticker on it mentioning how it's disabled unless you use an 11th gen CPU on the board, in which case it is connected to the CPU at PCIe 4.0 while the others are 3.0.

    Ultimately its a cost issue. Server grade MOBOs handle PCI-E breakout better because they can cost hundreds of dollars more. An 8-10 layer gamer board has to be cheap. A 12-16 layer Server board - with additional layers to break out the lines - ill perform better - with the right chipset. You've shown some of these machines on LTT. More connectors, less blocking, more SRAM caches, etc. When money is not a limit the bottlenecks can be removed up to a point.

  • @jdrissel

    Before Oracle bought Sun, Sun made X86 servers that had a separate pci chipset for each pci slot & device. They could do a lot more IO than Dell or HP servers with what would appear to have been similar specs, and it was more consistent too. For example if you had a program (say an email server) that mostly received network traffic and writes to the disk, it could keep both the disk and the nic in action at once. On the others when you were writing a bunch of spam to disk, the network interface would slow down and if you a pingflood at say 10% of the network's rated speed the disk would slow down. And this would hold even if your email server was just writing to /dev/null for testing! That's right, a ping flood can slow down your disk IO on most systems because they pci bus has to deal with that data and while it is doing so the bus can not deal with disk IO. Yes I know that most of this goes around the cpu via dma, but it does not go around the pci chipset.

    This is in part why pcie gen 4 whilst not giving graphics cards any speed boost, alleviate some of the problems by doubling the theoretical max speed per lane, so a you only really needs 8 to have the same bandwidth available to it, and leaving plenty for nvme storage. Gen5 in theory means a GPU would only need to have 4 lanes to have the same bandwidth available to it as currently on gen 3, again more lanes potentially freed up for storage and other things. It is rumoured that the next generation of ryzen will move to gen5, and the 12th gen intel too.
