The three different CPU issues affect chips from Intel, AMD, and ARM (no mention anywhere of PowerPC or Apple's own A-series), and affect virtually all devices sold in the last 15 years - computers, tablets, smartphones, etc.! That's gonna be one heck of a clean up bill! :-( The _only_ processors which will suffer a performance slowdown as a result of these problems are Intel ones. Spectre affects all chips and the fix does not affect performance. Meltdown affects processors built since 1995 by *Intel* and the fix will slow them down up to around 65%. There's actually THREE issues (at least), despite the fact that the media is over-hyping just those two. Very true. However, the ones affecting AMD had little to no chance of affecting performance from the very beginning whereas the Intel one was looking to be fairly disastrous. That Microsoft and Apple managed to keep the performance hit at a bare minimum is a testament to their ability. That last line is sure to trigger Peter the Klöwn. Microsoft simply waited for Apple to fix the issue, then copied them. ;-) Because the operating systems are so similar and Apple's code is so stellar, right? |

Spectre affects all chips and the fix does not affect performance. Meltdown affects processors built since 1995 by *Intel* and the fix will slow them down up to around 65%. Bull****. I tested my system with Geekbench4 before and after the patch. The single-test was slowed by around 1%, the multi-test by somewhat less than 2%. This does not involve lots of I/O, but it indicates that processor speed is very little affected. The measured values are barely higher than differences due to background tasks in the single test. Both values are not at all "being able to be felt" by the user. Notice that my machine constantly runs 3 diffferent databases too Either post a video of you doing the test of post some data proving what you claim. Idiot You are even way too stupid to do such a simple benchmark yourself, otherwise you would not make such ridiculous demands. But thats SlimeSnit for us, the dumbest clown known to mankind Says the emasculated German who allows migrants to rape the female members of his society and who didn't bother to show his own benchmarks out of an inability to "do such a simple benchmark [himself]". |

His post was sheer idiocy. CO2 is not a pollutant - period. Human caused "climate change/global warming" is junk science at its worst. Idiot Another thought-provoking and irrefutable post by Mainz's greatest export, Peter the Klöwn. A funny thing about your sort is you believe that putting down others makes your point valid and that resonates in your little echo chambers as some sort of truth. Says the hypocrite who just defended someone calling another poster an "idiot." While there is wisdom in crowds... ... there is none in your posts. *plonk* Like the rest of the science deniers, go ahead and stick your head back in the sand. I'm not a science denier, but I do deny results which come from a hand-picked set of scientists. If 1,000 scientists are asked about climate and 100 of them say that humans are causing global warming, is it honest to grab those 100 and then claim that 100% of scientists believe in global warming? I don't believe that it is and yet that's what happened. |

My previous car, a Jeep Patriot, did. However, neither my BMW 428i nor the Infiniti QX30 have one. The Patriot, funny enough, was a total piece of poop in _warm_ temperatures. |

In article , nospam range is only a problem for long road trips, and in those cases, rent a vehicle. eventually, that won't be a problem, as more charging stations are built. I think some of you guys need to calculate the power rate needed to charge the higher range cars in any sort of reasonable time. You'll find it quite high. Then you have the problem of supplying that power at a safe voltage, and without such a high current needed that even Mr Muscles can't lift the charging cable, never mind plug it in. It's not that bad, one or two cars at a time. These days it's not unusual at all for houses to have 200A service and putting a 100A 240V outlet in the garage for a charger does not require a major retrofit. Where it gets bad is when you start thinking about doing that in every house in the country and the degree to which the grid needs to be enlarged in order to deal with that load on a constant basis. It'll happen, and the money is there to make it happen because it's the same money that is currently going into purchasing gasoline, but it's not going to happen today and it's not going to happen tomorrow. But you can go out right now and buy a BMW i3 at your dealer today, get a charger installed on your existing service panel, and have a whole lot of fun driving fast right now. It's not cheap, but that's how it goes. --scott -- "C'est un Nagra. C'est suisse, et tres, tres precis." |

In article , Doomsdrzej Are they heated through the use of a block heater or is there some other solution I'm not aware of? the batteries are heated and shortly before leaving, you can preheat the cabin via a smartphone app. What he is asking is whether the batteries are heated using their own power (which would be limited) or external power (like the block heater used to keep gasoline engines warm using the AC mains current). based on that, you shouldn't trust a *gas* powered vehicle in such temperatures. many gas powered vehicles have engine block heaters because they won't start in extreme weather. This is all true, but modern oil technology combined with fuel injection systems have made matters a whole hell of a lot better than they were back in the eighties. But when you think the gasoline engine had been around for ninety years before anyone managed to make one start consistently in Alaska, you have to realize how quickly the electric technology is moving in comparison. --scott -- "C'est un Nagra.
