Because none of them went in mud.

OR you can realise, torque curves can be adjusted, can be geared, can be pulsed (software controlled voltage/amps/rotor management/stator adjustment etc) to fit the torque required.

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.

i know but its only there 2nd gen mobile chips lol

But it's still the 3rd generation of Ryzen.

well i have no clue what hedt is, but heck its in the marketing literature and i want it! lol

i never pay any attention to internals of laptops i am a desktop guy

HEDT stands for High End DeskTop, which would be Threadripper and Intel X79/99/299.

10 minutes ago, pas008 said:

yes they labelled it as 3700u only nothing else

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.

Just now, SlimyPython said:

also i did say 3rd gen ryzen in the title too

Yeah, he's asking where in Intel's marketing (which probably isn't their marketing), or in the article.

Where in the link or pic does it say 3rd gen?

In the name: R7 3700U.

It's a third generation Ryzen, using the Zen+ architecture.

The Raptor is more designed to be an off road racer,

Hence why I called it a nimble off roader.

@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).

Found one in mud:

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.

Does not mean it's "useless" or "stupid"

Didn’t say either of those things, don’t put words in my mouth.

gonna get stuck in the mud"

Every vehicle will get stuck. ICE off roaders are very likely better at getting unstuck.

@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.

Just now, TechyBen said:

And Tesla get to set the motor and torque curve. So, false equivalences?

An electric motor’s torque curve is higher at lower RPM. You can’t change that.

3 minutes ago, TechyBen said:

Or is this something that can be done in the power delivery to the motor,

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.

in an ICE engine, we'd say fuel/air mix and "timings" which is also SOFTWARE these days)

And? ICE torque curves start at their low end at low RPMs. You can’t change that either.

That's not 3rd gen Ryzen, it's Zen+. 

Third gen Ryzen =\= Zen 2.

uArch generations and product line generations are not the same thing.

You do know the biggest trucks in the world sometimes have electric motors? What are you even going on about here?

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.

In other words. 

 

If they manage to do it, there will be a lot of strain on the mechanism that will control it. 

 

 

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.

1 minute ago, GoldenLag said:

It would be one of the few solutions. 

 

That depends on how the software is done. 

I would involve managing how much torque you get on standstill. 

 

Which would need to be configured in software. 

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.

people insisting "oh just get a solar or wind generator, you'll never need to go further than 400km either" are ignoring the whole point of having a truck to get work done. 

They're also ignoring that more range also equals needing to refuel less often, even if it takes a tad longer per refuel.

Just now, GoldenLag said:

hence throttle control. 

 

not to mention all of this can be adjusted in software. having something doesnt mean its allways on. 

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.

cant you just not "pedal to the metal"? having it on tap doesnt mean you will neccesarly use it. does mean you need to be better with throttle control

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.

2 hours ago, TechyBen said:

Even better, do they realise all this is tuned in the computer? Same as in the computer in their ICE car.

Can't tune out the torque curve inherent to electric motors.

YT is going to be full of Cybertruck fail videos after the Urban buyers suddenly think they know how to offroad. That'll be some high humor when it happens.

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.

Then there's the electric powertrain, which is practically maintenance free with peak torque available right on tap. 

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.

Besides, no cattle farmer works 24/7/365 and/or covers ~400 kilometers every single day; at least, not in my knowledge!

They don't have to do it every day, but going hundreds of miles, back and forth, isn't uncommon.

Maybe 2-3 hours every day, tops.

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.

I don't have a time machine. I built this machine in June 22, 2013.

 

At the time the option was i7-4770 (Q2'13) that supports Virtualization, or the i7-4770k (

Q2'13) which does not. The 4790K came out an entire year later (Q2'14.)

 

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.

The GPU makes a difference provided there is a workload that maxes it out, which is largely the realm of synthetic benchmarks and a few games like FFXV.

Other than Syaoran running out with their current 8GB config, a GPU upgrade would be the better upgrade. RAM speed doesn't make a huge difference after a certain point in real games, and for a Ryzen chip, Syaoran is already at that point. A GPU, on the other hand, WILL churn out more frames if not bottlenecked, or higher quality frames for a prettier experience.

The CPU makes a difference only if the newer cpu is a 25% increase in single-threaded performance, which is something only achieved after like 5 years, and only if you pick the most expensive model.

 

For example I have a i7-4770, upgrading to a Ryzen 3900X is the only part that hits that performance jump.

The 4770 was never the most expensive/top of the line model within Haswell. It has both a clockspeed and IPC disadvantage.

https://cpu.userbenchmark.com/Compare/Intel-Core-i7-4790K-vs-AMD-Ryzen-9-3900X/2384vs4044

Moving to a more powerful chip in 4th gen Core i, and that ~25% difference in single core (totally arbitrary number, by the way) literally halves itself when both chips are left at stock.
