    Do you think phone-laptop or phone-tablet convertibles will ever take off?

    Posted: 27 Mar 2021 01:09 PM PDT

    Asus tried making a phone-tablet convertible way back with their Transformer series, Windows Phone had a feature where you could plug into a dock and use it as a full-Windows workstation (kind of), and in 2018, Razer showed off their concept for a phone-laptop convertible. As far as I know, Asus gave up due to poor reception and poor sales, Windows Phone went the way of... Windows Phone, and Razer never made a mass market device from their venture. Even now, Pine64's PinePhone has an upgraded convergence edition, continuing the concept of a universal Linux distro for phones, tablets, and desktops that Ubuntu started.

    There are a lot of benefits to this, one is that assuming you had a phone, laptop and desktop as separate devices, this can save a lot of hardware, especially since in most cases, you're only using one device at a time. Lots of people already use their laptops as desktop replacements, so if a phone-laptop convertible can match that, then it can easily become someone's only device. There's an environmental benefit too, phones are much more power efficient per unit computation power, and since you don't need to upgrade the laptop chassis or your desktop peripherals nearly as often as the active compute hardware, you'd be producing less e-waste. I personally also really like the idea of having one computing device to rule them all.

    Do you think this concept is straight up dead in the water, or, as phones become more powerful (especially since laptop chips like the Qualcomm SQ1, Apple M1, and the upcoming Intel Lakefield can already be passively cooled and still be quite powerful), operating systems improve to support seamless transition between device modes (Some Linux distros are working hard on this, and Google's Fuschia OS is planned to replace both Chrome OS and Android in the future), and with the USB C and Thunderbolt standards offering fast I/O, it will actually gain the mass adoption in the future that it isn't able to achieve right now?

    Can the latest phone outperform a laptop from a few years ago?

    Posted: 27 Mar 2021 06:00 PM PDT

    If we took the latest top of the line Snapdragon or Apple A series smartphone and compared it to a high end thin and light laptop like the Surface Pro or Macbook Air circa around 2016 to 2017, how would it compare? I have no doubt that the phone would be more efficient per unit compute power, but would it be able to beat the older laptop in raw performance?

    I'm curious especially since both Qualcomm and Apple are now releasing ARM processors that on paper don't seem that much more powerful than what's in their phones, but geared toward full laptop computing, so does that mean that even a modern phone can outcompute older laptops?

    Is it possible that 6600 and lower RDNA cards might not have Infinity cache?

    Posted: 27 Mar 2021 04:33 AM PDT

    Xbox consoles don't have infinity cache and use ~10GB/s per CU clocked sub 2ghz. a 192 bit bus puts the bandwidth of the 6700xt at close to 400GB/s, and a cut down 6700xt will probably be ~32 CU like the rx 570 vs 580 (36 vs 32). Keeping the same bus and dropping core counts further, while targeting 1080p would likely mean that there is enough memory bandwidth to remove Infinity cache.

    That could significantly reduce die size, since the Xbox Series S has a die size of ~197mm² and 8 Zen 2 cores are ~75mm², so assuming that the rest is just the 20 CU+IO, that means that a 20 CU Rdna 2 gpu would be ~125mm². A 40 CU 6700xt is ~335mm², so thats ~38% of the size for 50% of the cores.

    Ccleaner: Yes or no?

    Should I have the Ccleaner installed on my computer? Is it helpful to have that program?

    [Linus Tech Tips] Are Hard Drives Still Worth It?

    So did GloFo get any x86 IP, or is Intel the only foundry that can offer customers x86 for their own designs?

    Posted: 27 Mar 2021 10:40 AM PDT

    It sounded like Intel is letting other companies make their own x86 cores (in addition to modifying Intel's, which they also seem to be offering) and to my knowledge, they're the only company that does that? I know AMD has their own semi-custom division, but those SOCs are still based on AMD's Jaguar and Zen2 uArches.

    I can't help but wonder whether or not GloFo and AMD would have had to split if they could have done the same thing.

    ...Then again, considering the inefficiencies of x86's variable instruction length, and how behind GloFo currently is, it might not have mattered, and it's questionable if it even matters now considering Intel is behind, and I'm pretty sure a lot of the x86 and even x86-64 patents have either already expired or are about to, but.

    It's still a sorta interesting question to me?

    Would Intel have been able to stop AMD from going "come make your own x86 core if you use our foundry"? Then again, would AMD/GloFo have had the capacity for that?
