no, you tell us why you think the next ten years are going to be different than the last thirty

If the processor comes with builtin GPU, NPU and RAM will you be really building the system

Sure. Building a PC already is barely building anything. You buy a handful of components and click them into each other.

One possible reason: to achieve the performance improvements, we are seeing more integrated and soldered-together stuff, limiting later upgrades. The Framework Desktop from the modular, user-upgradeable laptop company, has soldered-on memory because they had to "choose two" between memory bus performance, system stability, and user-replaceable memory modules. If the product succeeds and the market starts saying that…

That’s a laptop. It’s soldered for space constraints.

There are high speed memory module form factors. It just adds thickness, cost, expense, and they’re not widely available yet.

Most use cases need the high speed RAM attached to the GPU, though. Desktop CPUs are still on 2-channel memory and it’s fine. Server configs go to 12-channel or more, but desktop hasn’t even begun to crack the higher bandwidth because it’s not all that useful compared to spending the money on a GPU that will blow the CPU away anyway.

>Joystic port or MIDI port? Back in the days I only ever thought of the DA-15 as the Game port[1]. To me it was only meant to welcome a joystick and play flight simulators. Little did I know that it could also be used as an output to send MIDI commands to a MPU 401-UART!

With no latency of course because USB hadn't been invented yet.

>My SC-55ST came without a power supply. That was the opportunity to understand better the power requirement marking on the back. Voltage and Amperage are obvious but one must also pay attention to the polarity sign. The SC-55ST uses a negative center[7].

This is the "standard" for guitar effects pedals due to the ordinary switching power socket component on their PCB. The outer connector of the barrel jack does the switching by pushing the conductor away from the internal battery pole and over to the external supply when it is plugged in. This would switch the same way physically whether it was positive or negative, except these are often very sensitive or high-gain audio circuits and every bit of earth ground integrity can be essential for the metal enclosures and coaxial cables to shield the inner audio signal properly.

This SC-55ST may not have an internal 9V battery like a guitar pedal would have, but it was designed to run on a Roland "Boss" A/C adapter anyway which is the top shelf wall wart having highly regulated clean power for studio use. Roland set the standard for center ground with their Boss pedals and adapters which basically steamrolled everyone else. Since for this application it's not the power supply that's using any shielding at all, but the audio needs as much shielding as it can get.

Honest question: Will building a high-end PC still be a thing in 10 years? I've built all of mine in the last 20 years. Just finished my first AMD build. But I don't think it'll be possible or allowed after a few more CPU iterations. Sure, you'll be able to do builds with the CPU tech available up to when it stops, but I seriously doubt that the cutting-edge chip tech ten years hence will be available to hobbyists. T…

The only market for desktops is gaming. Hence nvidia will just slap a cpu on their board and use the unified memory model to sell you an all in one solution. Essentially a desktop console.

Maybe some modularization will survive for slow storage. But other than that demand for modular desktops is dead.

Cases will probably survive since gamers love flashy rigs.

This is nice, but without a CRT monitor (he's using an IPS) it's not quite the real thing regarding the actual on-screen experience.

It's much less important for VGA games than for console games. Most used 320x200 resolution, which was line-doubled to 320x400 then displayed on a monitor capable of at least 640x480, so you had distinct and moderately sharp pixels. The monitor was natively progressive scan, so you didn't get the exaggerated spacing between scan lines that you got on consoles using non-standard field timing to force 240p on a 480i TV. And the refresh rate at this resolution was 70Hz, but very few games ran at 70fps, so you lost most of the benefit of the low persistence of CRTs.

I always really liked the handle on my old upgraded lenovo E73. It made it much easier to transport when going to university and back for the holidays, and I'm sad that most cases don't have one. Even a hinged one that sits flat to the top of the case when folded down would be awesome

I'm pretty sure the "Framework Desktop" is a desktop, not a laptop.
