  1. I wouldn't constitute dry, loose top soil, non compact frozen water, or a rock bed as mud. So far, the BEST case you've presented is a car going through a slightly muddy back road.
  2. So, what I already said. Got it. Except that, by their very nature, electric motors produce more torque at lower RPM. Also, your video still does not address what I said. They're still running those vehicles on hard ground, with (At worst) a thin layer of loose soil on top.
  3. HEDT stands for High End DeskTop, which would be Threadripper and Intel X79/99/299.
  4. The first number in the 4 numeric section of the SKU is the generation of the chip. Ryzen didn't get mobile chips until gen 2, and mobile chips are one uArch behind their desktop counterparts. Same thing as what Intel used to do with HEDT.
  5. Yeah, he's asking where in Intel's marketing (which probably isn't their marketing), or in the article.
  6. In the name: R7 3700U. It's a third generation Ryzen, using the Zen+ architecture.
  7. *Casually goes through with bullet necklaces*
  8. @dalekphalmWhen people say that infrastructure can't support mass EV use, they mean that the electric grid isn't being fed enough energy to charge that many EVs. If you charge every night, and just about everyone else does too, a huge amount of power is being drawn. Whereas only refilling when needed helps alleviate that issue (and other fuel sources circumvent entirely).
  9. And? The car wasn’t dug in at any point, and the mud was a fairly thin layer. All you’ve shown me is a Tesla driving on an ever so slightly slippery dirt road. Not an EV going off road. Nor is snow driving the same as mud. Snow compacts under the tire and gives it something more solid to grab on to. Didn’t say either of those things, don’t put words in my mouth. Every vehicle will get stuck. ICE off roaders are very likely better at getting unstuck.
  10. @EarthWormJM2 Are you going to keep rehashing early parts of arguments? I need to know so I can expect a higher number of nothingburger notifications.
  11. An electric motor’s torque curve is higher at lower RPM. You can’t change that. As I’ve already said, it might be possible. But Likely not, I doubt that hitting the sweet spot of being able to move the truck and not turning the tires into soft earth saw blades is going to align with the current needed to get the motor turning. And? ICE torque curves start at their low end at low RPMs. You can’t change that either.
  12. Third gen Ryzen =\= Zen 2. uArch generations and product line generations are not the same thing.
  13. Fun fact: @VegetableStu’s avatar is sweating because he’s within 50 miles of a 10980XE.
  14. If you’re taking construction, like large dump trucks, they also have better weight distribution on the ground, as well as being heavy enough to compact the ground underthem AND have off road wheels designed for them. Now that we’re done with the game of false equivalences, pickups, what the Tesla is, sometimes get stuck. What the ones good at getting unstuck have is moderate low end torque. Enough to move the truck, but not enough to consistently spin the wheels and send mud flying.
  15. Basically. Whereas the 6.7 Cummins in my truck can get out of mud with just idle torque 9 times out of 10. That other time requires, maybe, an additional 200-300RPM. Many other trucks can manage this as well.
  16. The only way to limit torque on an electric motor in software is to limit current (and heavily if you want to reliably get out of burying your vehicle), which may not be viable if the motors' startup voltage pushes too much torque.
  17. They're also ignoring that more range also equals needing to refuel less often, even if it takes a tad longer per refuel.
  18. Throttle control isn't going to fix the issue. You have a heavy vehicle forcing your wheels down, while your electric motor is going to send the maximum or near the maximum amount of torque, on ground that will easily give to outside influence. A heavy truck, with high torque (not horsepower) is going to be more prone to digging up earth. And trying to tune for this would require a massive hit to early acceleration, significant cut in current to the motor(s) (which could easily run into start up voltage issues), and probably changing the drive line to one that eats that torque. To rely only on software is a halfassed solution. And given that we're dealing with Tesla, we'll get a quarter assed solution and be told that it's two whole asses.
  19. The problem is low end torque. Electric motors have more torque with the less RPM you have, meaning it'll insanely easy to overtorque on sand and mud, turning your wheels into excavators. Can't tune out the torque curve inherent to electric motors.
  20. Assuming that there are that many legitimate preorders. Or that Tesla doesn't sink before they start production. Or that any of us live that long.
  21. Nothing is "practically" maintenance free, and high low end torque isn't always a good thing. This thing will likely have issues with soft ground, namely mud and sand. They don't have to do it every day, but going hundreds of miles, back and forth, isn't uncommon. Meanwhile, it usually takes me 20 minutes every week for my truck, and I don't need to leave something plugged in that eats up 12A by itself.
  22. 4770K supports virtualization. It just doesn't support VT-d, which means no hardware passthrough. Not that big of a deal for a quad core system.
