  • The M1 going full tilt will use 35+ watts, vs like the A15 which I think people guess is limited to around 7 watts. I have a 10th gen and it gets outstanding battery life doing basically anything. Meanwhile the M1 powered iPads can actually drain pretty quickly. The CPU is efficient compared to a core i9, but 30 watts in a tablet is a lot for their battery.

    But the latest phone CPU constrained to say sub 10 watts would last an insane amount of time on even the smallest battery you'd put in a tablet/keyboard glued to a tablet running Mac OS. I get 10-15 hours of battery life on my M1 MBP, and most of the time I don't really need all that performance. If I could double that that would be insane.

  • The 12" MacBook was more or less a revival of this, but with actually fairly good hardware vs the cheapest shit they could slap together.

    One of those machines, but with an iPhone CPU (not even the full M1) would be killer. Outstanding battery life, more than enough horsepower to casually browse the web, and well I guess that's it. If only the modern web wasn't so hideously bloated.

  • At my company we store our regex in the database with linebreaks in it, but when it's actually called to be used those line breaks are stripped out. That way regex that looks for X can all be all on one line and actually readable.

  • If you bought a $120,000 Cybertruck you're probably still doing just fine.

    I'm lax on the Model 3 and Y. They're relatively cheap and affordable everyday cars. But Cybertruck? You knew by then he's a lying douche and you still gave him a shit ton of your money.

  • Every picture I've seen has been an outside pin. So my theory is it's the cable getting tugged for cable management and even though it's clipped in, it's not making as good of contact.

    That or just a bad cable design. I've bought a few cables from cablemod and I'm not happy with the wiring they used. Their website says "Crafted with 16AWG wiring" but they also brag about the flexibility of their cables so I assume they're using stranded wires instead of a solid core so you lose a decent chunk of ampacity (and heat sinking).

  • High end GPUs are always pushed just past their peak efficiency. If you slightly underclock and undervolt them you can see some incredible performance per watt.

    I have a 4090 that's underclocked as low as it will go (0.875v on the core, more or less stock speeds) and it only draws about 250 watts while still providing like 80%+ the performance of the card stock. I had an undervolt that went to about 0.9 or 0.925v on the core with a slight overclock and I got stock speeds at about 300 watts. Heavy RT will make the consumption spike to closer to the 450 watt TDP, but that just puts me back at the same performance as not underclocked because the card was already downclocking to those speeds. About 70 of that 250 watts is my vram so it could scale a bit better if I found the right sweet spot.

    My GTX 1080 before that was under volted, but left at maybe 5% less than stock clocks and it went from 180w to 120 or less.

  • The 8800 Ultra was 170 watts in 06

    The GTX 280 was 230 in 08.

    The GTX 480/580 was 250 in 2010. But then we got the GTX 590 dual GPU which more or less doubled

    The 680 was a drop, but then they added the TIs/Titans and that brought us back up to high TDP flagships.

    These cards have always been high for the time, but quickly that became normalized. Remember when 95 watt CPUs were really high? Yeah that's a joke compared to modern CPUs. My laptops CPU draws 95 watts.

  • Sata data doesn’t do enough power to cause any damage to itself. Serial data lines don’t care if you short them. Sata power has grounds in the way so you can’t send 5v to 3.3v or 12v to 5v.

    You’ll break the sata cable before you cause any damage to your computer (ask me how I know)

  • First thing I’d check is unplug all sata cables from the board, turn off your power supply, give it a few minutes, then turn it on, then your PC.

    PCs are loaded with poly fuses that self reset after some time. It can take up to a day for some really fickle ones. So maybe just sleep on it.

    While you’re waiting/unplugging inspect the hard drive, the sata cable, and the port for damage.

  • There’s nothing wrong with doing this. A motherboard that doesn’t support sata hot swap is by far the exception not the rule. I have never encounter a board in the last 10 years that doesn’t support this.
