If you read my scoop last week, I bet you’ve been wondering — how well could a Snapdragon chip actually run Windows games? At the 2024 Game Developers Conference, the company claimed Arm could run those titles at close to x86/64 speed, but how fast is fast? With medium-weight games like Control and Baldur’s Gate 3, it looks like the target might be: 30 frames per second at 1080p screen resolution, medium settings, possibly with AMD’s FSR 1.0 spatial upscaling enabled. ↫ Sean Hollister at The Verge Those are some rough numbers for machines Qualcomm claims can run x86 games at “close to full speed“.

Hackaday recently published an article titled “Why x86 Needs to Die” – the latest addition in a long-running RISC vs CISC debate. Rather than x86 needing to die, I believe the RISC vs CISC debate needs to die. It should’ve died a long time ago. And by long, I mean really long. About a decade ago, a college professor asked if I knew about the RISC vs CISC debate. I did not. When I asked further, he said RISC aimed for simpler instructions in the hope that simpler hardware implementations would run faster. While my memory of this short, ancient conversation is not perfect, I do recall that he also mentioned the whole debate had already become irrelevant by then: ISA differences were swept aside by the resources a company could put behind designing a chip. This is the fundamental reason why the RISC vs CISC debate remains irrelevant today. Architecture design and implementation matter so much more than the instruction set in play. ↫ Chips and Cheese The number of instruction sets killed by x86 is high, and the number of times people have wrongly predicted the death of x86 – most recently, after Apple announced its first ARM processors – is even higher. It seems people are still holding on to what x86 was like in the ’80s and early ’90s, completely forgetting that the x86 we have today is a very, very different beast. As Chips and Cheese details in this article, the differences between x86 and, say, ARM, aren’t nearly as big and fundamental as people think they are. I’m a huge fan of computers running anything other than x86, not because I hate or dislike the architecture, but because I like things that are different, and the competition they bring. That’s why I love POWER9 machines, and can’t wait for competitive non-Apple ARM machines to come along. If you try to promote non-x86 ISAs out of hatred or dislike of x86, history shows you’ll eventually lose.

In a 2024 Game Developers Conference session titled “Windows on Snapdragon, a Platform Ready for your PC Games,” Qualcomm engineer Issam Khalil drove home that the unannounced laptops will use emulation to run x86/64 games at close to full speed. Those laptops may be coming fast. Qualcomm has confirmed it will launch Snapdragon X Elite systems this summer, and unannounced consumer versions of the Surface Pro 10 and Surface Laptop 6 are expected in May with those chips, sources told The Verge. ↫ Sean Hollister at The Verge I’m genuinely curious to see if they can fulfill this promise. I really want widespread availability of ARM laptops. My hope is that we end up with a more standardised ARM landscape, making it easier for operating systems to support these new machines.

What if the kind of laptop you’re looking for just isn’t available from any of the major or even minor manufacturers? You know exactly what you want out of a laptop, and while quite a few fulfill many of your requirements, the requirement that matters most just isn’t being made. It’s not a case of “too expensive” or “too cheap” – simply nobody will sell it to you. From HP, Dell, Apple, down to smaller and local OEMs, none of them can serve your particular set of needs. For me, that particular requirement, that particular need is that of the laptop with an 8″ to 10″ screen size. Even the most portable laptops sold by well-known brands today stop at 13″, often even 14″, with nowhere to go but up. I currently have a 13.3″ laptop – an otherwise excellent XPS 13 9370 with a gorgeous 4K display – but as much as I love it, it’s just too big and heavy for me. I want something smaller, no bigger than roughly 10″. Why? Well, I use my laptop in exactly two locations: on the couch in one of our two living rooms, or in bed (okay that’s technically three locations). That’s it. I work from home on my workstation, I play games on my gaming PC, so I don’t need big performance on the road, nor do I need a big portable display to make working on the go bearable. On top of all this, I have two small kids running around the house, so a laptop that is easier to quickly close and put out of harm’s way is very welcome. And considering the most intensive workload it’ll ever have to contend with is playing YouTube video, I don’t need the latest Core i7 or Apple M3 either. Why not a tablet, then? First and foremost, I want to use a desktop operating system, not Android or iOS, since writing OSNews posts or doing a quick translation for my job are not fun experiences on mobile operating systems. On top of that, a tablet with a keyboard accessory often makes use of a kickstand and flappy keyboard, which are cumbersome to use on the couch, in bed, or on your lap. The exception here would be the iPad with a Magic Keyboard, but that’s an incredibly expensive affair and an Apple product, so obviously a no-go. Luckily, while the kind of small laptop I’m looking for is not available from one of the major OEMs, there are a small number of specialised OEMs that do focus on making small laptops. Roughly, the devices they make fall into one of three pricing categories. First, there’s the high-end – these usually start at around €800 or so and get well over €1000, and have a decent set of specs, often focused on gaming by opting for AMD APUs. A major player in this market is GPD, who’ve been offering products in this segment for years, and are actually a decently well-known brand at this point, even being featured on major YouTube channels like Linus Tech Tips. Then there’s the very low end, a market segment drowning in the exact same 7″ laptop priced at €250 or so, sold under a variety of brand names, sporting the same low-end Celeron chip and rather crappy display. It’s also quite thick, made out of cheap plastic, and every review I’ve seen of these are not particularly positive. Unless you know what you’re getting into, do not buy these. They’re e-waste trash. In recent times, however, a middle segment has slowly started to take shape, coming in price points in between the low and high end, with reasonable specifications and build quality, without going overboard. This was exactly what I was looking for. Aside from price and specifications, mini-laptops also come in a variety of different input layouts. Being smaller than other laptops, some compromises will have to be made, and it’s this particular aspect that will most likely play a major role in which models appeal to you. The gaming-focused mini laptops will often come with dual joysticks and face buttons, while other models will come with a more traditional keyboard and trackpad, and the smallest laptops in this category ditch the trackpad in favour of a little sensor pad in the top-right of the keyboard, or a ThinkPad-style nipple. Having kept and eye on this market for years now, I knew exactly what I was looking for: I wanted a traditional keyboard and touchpad layout, with medium specifications, a capable display, and all-metal construction, for no more than roughly €400-500. Clearly, the time to strike was now, as the small, budget-oriented OEM Chuwi had just updated its 10″ mini laptop with Intel’s latest low-power processor, the N100. The Chuwi Minibook X (2023), as it’s called, has an all-aluminium construction, and comes with quite decent specifications, and I managed to snag a new model through their eBay store for a mere €320 (I asked them for a discount down from €400 , and they gave it; I did not mention who I was or that I run OSNews). It has the aforementioned Alder Lake Intel N100 – released earlier this year, it’s an Intel 7 processor with 4 cores and 4 threads (so no hyperthreading) with a maximum turbo frequency of 3.4 Ghz, with a TDP of just 6 W. It’s not going to compare well to the various Core i3/i5/i7 processors, of course, but considering the type of device, it makes perfect sense to opt for something like the N100. Furthermore, this device is packing 12 GB of LPDDR5 RAM running at 4800 Mhz, and my model comes with a 512 GB SSD. The display is a 10.3″ panel with a native resolution of 1920×1200, with a refresh rate of only 50Hz (although some people managed to reach 60Hz and even 90Hz), and support for touch. Ports-wise, it has two USB-C ports (one marked as compatible with charging – I haven’t dared

There’s a channel on YouTube called The Proper People. It’s two guys who travel all over the United States (and in a few cases, elsewhere too) exploring abandoned buildings, and recording both the exteriors and interiors for posterity, since many of these buildings suffer from massive decay and are often slated for demolition. These buildings have histories and stories that otherwise would be lost to time. They are incredibly respectful of the buildings they explore, and they will not break open locked doors or windows, and only traverse open and unlocked doors or openings borne out of natural decay. They never take anything from the sites they visit, and abhor what urban explorers call “staging”, where you move furniture and objects around to invoke or imply stories and things that aren’t there. Their videos are also very calm, muted, quiet, and only occasionally use atmospheric music for some of the more artistic shots. As a sidenote, they also happen to have the absolute best intro music of all time. One of the things you quickly notice as you see these buildings, and explore their interiors, is just how solidly made and beautifully detailed they were. Whether they’re exploring an 19th century Kirkbride mental asylum, an early 19th century power plant, or a mid-20th century hospital – they all tend to be made not just to serve a function, but also to be beautiful and solid, both inside and out. Walls, ceilings, and doorways are beautifully detailed in masonry or woodwork, light fittings are solid and ornate, and even access corridors or storage basements have gorgeous vaulted ceilings, decorated walls, and ornate pillars. The contrast to modern buildings couldn’t be starker. Buildings and workplaces of today are littered with drop ceilings, flimsy dividers, open plans, endless amounts of glass, all in styles so minimalist it just makes spaces feel cold, uninviting, and lacking in human scale. Modern buildings and interiors are temporary, ephemeral, built not for humans, but to a bottom line and some designer’s fancy – these old hospitals, factories, and even power plants are permanent, enduring, and made to human scale. They served as much as a status symbol for whatever ruthless capitalist owned the building as they did as a place for that same ruthless capitalist to extract wealth from mistreated workers. This juxtaposition, of the minimalist, soulless, flimsy and cheap-looking exteriors and interiors of modern buildings on the one hand, and the beautifully detailed, skillfully crafted, and human-scale exteriors and interiors from these older buildings on the other, is something that kept creeping back into my mind during my use of the MNT Reform. This is a device built by people who deeply care, who are very opinionated, and know exactly what they want to make – very much the opposite of the cookie-cutter dime-a-dozen laptops that flood the market today. MNT was so kind as to send me a Reform, at some risk to them because I am definitely not the kind of customer the Reform is typically aimed at. Yet, after a few months of use, I can confidently say this is one of the most unique devices I’ve ever used, and one that’s worth every cent. Let’s explore why. Brutalist hardware Let’s first dive into what, exactly, the Reform is. At its core, it’s an ARM-based laptop designed to run Linux, developed and built by a small team of people in Berlin. The Reform is unique in that it is designed to be open hardware, fully repairable and highly modular and upgradeable. It consists of a mainboard with an mPCIe slot, an M.2 slot for NVME SSDs, 16GB eMMC storage, and uniquely, a slot for a System-on-Chip module roughly the size of an SO-DIMM module that contains the processor and RAM. The keyboard and pointing device are internally connected through USB 2.0 and easily replaceable, too. The Reform is defined as much by what it does not have as by what it does have. You won’t find any surveillance devices inside the Reform – no webcam, no microphones, nothing. There have been laptops with little privacy switches or sliding covers for the webcam, but I don’t think I’ve seen a modern laptop that eschews cameras and microphones since the late ’90s. It’s one of the many examples of the Reform’s opinionated design choices. The configuration MNT sent me consists of the aforementioned mainboard, coupled with one of the processor modules they offer – in my case, the RCM4 A311D, which sports four 2.2GHz Cortex-A73 cores and two 1.8GHz Cortex-A53 cores, 4GB of LP-DDR4 RAM, and an ARM Mali G52 MP4 GPU that supports OpenGL/ES 3.1 through Panfrost. This module also supports Wi-Fi 5 and Bluetooth 5.0 through the integrated RTL8822CS. The A311D is just one of many modules available for purchase for the Reform, and during the writing of this review, MNT also added a brand new SoC module to its lineup – the RK3588, the most powerful option available for the Reform. It packs 4 ARM Cortex-A76 cores (up to 2.4GHz) and 4 ARM Cortex-A55 cores (up to 2.2GHz), 16GB or 32GB of RAM, and 128GB or 256GB of eMMC storage. It also sports an ARM Mali-G610 MP4 4-core GPU. Like with all other modules, the drivers for the A311D in my model are completely open source. When it comes to firmware, however, the A311D is not fully open source; there’s closed-source code in the Wi-Fi firmware and the boot/TF-A firmware. The other modules all also have various bits of closed firmware, except for the RKX7 module that uses a Kintex-7 FPGA and hence comes with a hefty price tag. Using the RKX7 module, you can have a fully open source laptop, from operating system down to the firmware, which is, as far as I can tell, unique. However, the amount of closed firmware code for each of the other boards is relatively small, and in some cases – such as with the LS1028A – can be avoided, too. If you care about

HP launched a subscription service today that rents people a printer, allots them a specific amount of printed pages, and sends them ink for a monthly fee. HP is framing its service as a way to simplify printing for families and small businesses, but the deal also comes with monitoring and a years-long commitment. Prices range from $6.99 per month for a plan that includes an HP Envy printer (the current model is the 6020e) and 20 printed pages. The priciest plan includes an HP OfficeJet Pro rental and 700 printed pages for $35.99 per month. ↫ Scharon Harding at Ars Technica Can I pay them not to put a printer in my house?

The business arm of Raspberry Pi is preparing to make an initial public offering (IPO) in London. CEO Eben Upton tells Ars that should the IPO happen, it will let Raspberry Pi’s not-for-profit side expand by “at least a factor of 2X.” And while it’s “an understandable thing” that Raspberry Pi enthusiasts could be concerned, “while I’m involved in running the thing, I don’t expect people to see any change in how we do things.” ↫ Kevin Purdy at Ars Technica Expect changes in how they do things.

Smartwatches at the turn of the century were a more motley assortment than today’s, with an even wilder range of functionality. If you had a few hundred dollars or so, there were some interesting options, even back then. But if all you had was $85 (in 2024 dollars about $150), you still weren’t left out, because in 2001 you could get the Web-@nywhere (the “Worldwide Web Watch”). Load up the software on your PC and slap it in its little docking station, and you could slurp down about 93K of precious Web data to scroll on the 59×16 screen — 10 characters by 2 characters — to read any time you wanted! That is, of course, if the remote host the watch’s Windows 9x-based client accessed were still up, on which it depended for virtually anything to download and install. Well, I want 95,488 bytes of old smartwatch tiny screen Web on my wrist, darn it. We’re going to reverse-engineer this sucker and write our own system using real live modern Web data. So there! ↫ Old Vintage Computing Research Y’all know the drill by now – I’m a sucker for these kinds of stories. What a great, extremely detailed read, with code to boot.

I always liked small laptops and phones – but for some reason they fell out of favor of manufacturers (“bigger is more better”). Now if one wanted to get tiny laptop – one of the few opportunities would have been to fight for old Sony UMPC’s on ebay which are somewhat expensive even today. Recently Raspberry Pi/CM4-based tiny laptops started to appear – especially clockwork products are neat, but they are not foldable like a laptop. When in summer of 2023 Sipeed announced Lichee Console 4A based on RISC-V SoC – I preordered it immediately and in early January I finally received it. Results of my testing, currently uncovered issues are below. ↫ Mikhail Svarichevsky I want one of these.

At CES 2024, ASUS unveiled a new standard for motherboards, graphics cards, and cases. Called BTF (short for Back-to-The-Future), it offers much cleaner cable management with power connectors at the back of a motherboard. More importantly, it fully ditches the ill-fated 12VHPWR plug in favor of a much tidier (and probably safer) 600W PCIe connector. ASUS claims computers with BTF components are easier to assemble since all plugs and connectors are located at the back side of the motherboard tray without other components obstructing access to power, SATA, USB, IO, and other connectors. Therefore, “you won’t have to reach as far into the depth of your chassis to plug things in.” BTF should also make cable management much more elegant, resulting in a tidy, showcase-ready build. ↫ Taras Buria at NeoWin The interior of PCs effectively hasn’t changed since the ’80s, and it feels like it, too. Many of the connectors and plugs are unwieldy, in terrible places, hard to connect/disconnect, difficult to route, and so on. A lot more needs to be done than putting the connectors on the back of the motherboard and integrating GPU power delivery into the PCIe slot, but even baby steps like these are downright revolutionary in the conservative, change-averse, anti-user world of PC building. I don’t say this very often, but basically, look at the last Intel Mac Pro. That’s what a modern PC should look and work like inside.

As I work on moss and research modern processor design patterns and techniques, I am also looking for patterns and techniques from the past that, for one reason or another, have not persisted into our modern machines. While on a run this week, I was listening to an old Oxide and Friends episode where Bryan, Adam, and crew were reminiscing on the SPARC instruction set architecture (ISA). SPARC is a reduced instruction set computer (RISC) architecture originally developed by Sun Microsystems, with the first machine, the SPARCstation1 (a.k.a. Sun 4/60, a.k.a Campus), being delivered in 1987. It was heavily influenced by the early RISC designs from David Patterson and team at Berkeley in the 1970s and 1980s, which is the same lineage from which RISC-V has evolved. Given the decision to base moss on the RISC-V RV64I ISA, I was interested to learn more about the history and finer details of SPARC. ↫ Daniel Mangum The sad thing is that SPARC is pretty close to dead at this point, with the two major players in the high-end – Oracle and Fujitsu – throwing in the towel half a decade ago. There’s some lower-end work, such as the LEON chips, but those efforts, too, seem to be going nowhere at the moment. Definitely sad, since I’ve always been oddly obsessed with the architecture, and hope to still somehow get my hands on the last UltraSPARC workstation ever built (the Sun Ultra 45, which is, sadly, incredibly expensive on the used market). There’s also a whole boatload of servers on the used market with fancier, newer SPARC processors, but as far as I know, none of those support any form of even barely usable graphics, making them useless for weird people like me who want to run a desktop on them.

Pastel cities trapped in a timeless future-past. Empty apartments drenched in nostalgia. Classic convertibles speeding into a low-res sunset. Femme fatales and mutated monsters doing battle. Deep, dark dungeons and glittering star ships floating in space. All captured in a eerie palette of 4096 colours and somehow, you’re sure, from some alternate 1980s world you can’t quite remember… ↫ Biz Davis The PC-98 is exotic, and a little bit mysterious. Of course, thanks to the internet, abundant emulation options, detailed YouTube videos, and more, all the information is out there – but I still find that the PC-98 carries with it an air of mystery.

We’re going to cover the Cortex A57 as implemented in the Nintendo Switch’s Nvidia Tegra X1. The Tegra X1 targets a wide range of applications including mobile devices and automobiles. It focuses on providing high GPU performance in a limited power envelope, making it perfect for a portable gaming console like the Switch. Tegra X1 consumes 117,6 mm2 on TSMC’s 20 nm (20 SoC) process and uses a quad core A57 cluster to provide the bulk of its CPU power. Each Cortex A57 core consumes just under 2 mm2 of area, and the quad core A57 cluster takes 13.16 mm2. ↫ Clamchowder at Chips and Cheese An old SoC still doing excellent work in the Switch.
