Tesla Model 3 Owners Vent about Polar Vortex Affecting Cars

Winter rarely brings surprises aside from how much it’ll snow, but the latest cold season has caught a certain group of folks off guard (alternate source sans paywall): new EV owners. Recent Tesla buyers, for instance, have taken to social media to complain about frigid temperatures reducing the performance of their vehicle’s batteries. As drainage is a decently reported issue, many are simply showing their naivety, but complaints related to a design element may have some merit: an allegedly poor handle has made doors especially difficult to open.

Ronak Patel, a CPA auditor in New Jersey, bought a Model 3 last August. He’s driven about 150 miles in the cold over the last few days. "My biggest concern is the cold weather drained my battery 20 to 25 miles overnight and an extra five to ten miles on my drive to work," he said. "I paid $60,000 to not drain my battery so quickly." Tesla isn’t alone in facing this flaw. Tesla [also] made a door design decision that is coming back to bite some buyers. The Model 3’s handles are flush with the exterior of the car and require customers to push on one side, then pull on the other to open them.

High Gain Versus Low Gain Settings on Headphone Amplifiers

Audio Science Review tackles whether it is better to use high gain or low gain settings on headphone amplifiers. Conventional wisdom says that the high gain setting on an amplifier adds noise as "there is no free lunch." A Schiit Magni 3 and JDS Labs Atom were analyzed during the testing by an Audio Precision APX555. The Schiit Magni 3 took a 3 dB hit to performance when comparing the low gain setting to the high gain setting. The JDS Labs Atom dropped from 115 dB SINAD to 101 dB SINAD when switching from low gain to high gain. It seems that low gain is superior!

The test matrix here is infinite in scope. What volume does one choose for each gain to test? After pondering for a second or two, I decided to go the defensible route of setting low gain to max and then matching the same in high gain. Both of these amplifiers have analog volume controls and in high gain, they can be touchy as far as getting accurate levels out of them but I managed to get close enough. For these tests, I chose to use 300 ohm test load as that is in my analyzer and hence, higher fidelity than my external dummy load.

10nm Cannon Lake CPUs are Available in the U.S.

10nm chips are now on store shelves, but probably not in the form you want. As spotted by dylan522p on Twitter, the Walmart, Amazon, and Newegg U.S. sites are listing Intel Crimson Canyon NUCs with i3-8121U CPUs, while SimplyNUC also has a section for them. These 10nm chips showed up in Chinese computers awhile ago, but this is the first listing I've seen in major U.S. retailers. Interestingly, the boxes also come with a 2GB AMD Radeon 540 GPU, as well as 8GB of LPDDR4 and a regular 1TB spinner.
For reference, a similarly priced, previous generation NUC with an i5-7260U actually boosts to a higher frequency than the i3, but doesn't support DDR4L memory. Discussion

AMD EPYC Rome 64-Core Server Versus Intel Dual Socket Xeon Platinum Benchmark

HotHardware has video of the C-Ray raytracing benchmark shown at the AMD Horizon Event. The AMD exhibit demonstrated just how powerful the new 7nm EPYC Rome architecture is with its new chiplet design that was leaked by AdoredTV. An Intel 8180M dual socket Xeon Platinum CPU server with 56 cores total and 112 threads was matched against a single AMD Zen 2 EPYC Rome 64-core CPU based server. Needless to say, the 7nm AMD EPYC Rome CPU easily won the battle. AMD CEO Dr. Lisa Su says that the 7nm EPYC Rome CPU will be a 64-core, 128-thread processor. The entire slideshow can be viewed here. Thanks @juanrga !

In addition, AMD has been able to add some security enhancements with Zen 2 as well, including hardware mitigation for recently discovered Spectre CPU vulnerabilities. AMD has also increased the number of encryption keys for virtualization to allow companies to support more virtual machines. Infinity Fabric is now in its second generation, and I/O per die has been optimized to improve both latency and power. While Infinity Fabric itself is being kept on a 14nm process, the accompanying chipset for Zen will be built on 7nm.

Nvidia RTX 2080 Ti Versus GTX 1080 Ti Benchmarks Are Out

According to Turkish tech website PC Hoc TV, they have conducted testing on the new Nvidia RTX 2080 Ti and compared it to an Nvidia GTX 1080 Ti at 4K resolutions. They experienced a 20% - 25% uplift in performance from the RTX 2080 Ti upgrade. Of course we don't know which driver version they were running during the testing and remember that Kyle said "If you are seeing any benchmarks between now and the ~20th (we think the 2080 launch and 2080 Ti launch will be split on different days possibly), you are likely not seeing cards benchmarked with its launch driver. So keep that in the back of your mind as you see performance leaks come forward."

Tested on the system with 7700K processor, the RTX 2080 Ti showed 20% - 25% more performance than the 1080 Ti display card. NOTE: The test has been performed at 4K resolution, so the data is eliminated in this way. Test System: GPU: RTX 2080 Ti CPU: Intel i7 7700K Windows Version: Windows 10 RAM: 16 GB 3200 MHz.

We Can Now Successfully Transplant Lab-Grown Lungs in Pigs

University of Texas Medical Branch researchers have successfully transplanted lab-grown lungs into pigs. They created lung scaffolds of pig lungs by removed all the cells and blood from pig lungs and then placed them in a vat of nutrients. The lungs started growing when they added cells from the recipent pigs' lungs and then they transplanted them after 30 days of growth. The transplants were successful and none of the pigs involved rejected the transplants. This is a huge step forward for this technology and could one day lead to the elimination of transplant lists. Imagine hospitals growing replacement organs for humans in the future. As far as I'm concerned this can't come soon enough. Read the paper here.

If all goes as hoped with the pig experiments, the researchers believe they could be just five to 10 years away from being able to create lab-grown lungs to transplant into people in compassionate use circumstances (people with life-threatening conditions and essentially no other treatment options).

PCs With Cannon Lake CPUs Won't be on Sale Until the Very End of 2019

In yesterdays conference call Intel confirmed that Cannon Lake will be out just in time for the 2019 holidays. We already knew they had delayed mass production until 2019, but waiting till the end of next year is huge. As a result Intel is hoping 14nm chips like Whiskey Lake and Amber Lake will tide their client market over for the next 16 to 18 months. I'm sure those chips will be fine performers, however, AMD is releasing 7nm chips next Spring and that's bound to capture some good PR. Good luck Intel.

So, this isn’t another delay as such, just a confirmation of exactly when in 2019 the launch will happen – but it’s kind of a disappointment seeing as the timeframe sounds pretty much as late as it can be (with consumer PCs launching by December).

Intel 10 nm Logic Process Analysis (Cannon Lake)

The folks over at Tech Insights have found the Cannon-Lake 10nm logic process and break down some of the innovation it brings to us. However, they aren't telling us why Intel is having so much trouble scaling their process up and bringing a complete lineup of 10nm processors to market. Regardless, the logic of the CL chip is pretty cool and hopefully Intel will work the fab issues out in the near future.

Agony Forced to Bend to Censors a Little

The horror game Agony (released finally for $27 on Steam) has been met with all kinds of obstacles over the last year due to its over-the-top sex and violence content. I think more the sex than the violence... Agony has given a statement as to what it has left in, and what it has cut in terms of content so that it could get distribution.

The censorship now affects only several seconds from two endings (out of seven) and some scenes that may be unlocked only after the end of the game. We will be able to show them to you in a video that we are planning to release soon. None of the scenes you have seen in the trailers and other promotional materials have been censored at all, and the game will feature those on all platforms: Gore - Brutal Sex Scenes - Lesbian and Gay Sex Scenes - Genital Physics - Eye Gouging - Heart Plucking - Children Heads Exploding - Setting Fire to Martyrs and Demons - Intense Violence - Strong Language - Drugs

I think I was at that UFC after-party in Vegas, but I do not recall children's heads exploding. Below is five minutes of gameplay, and I would certainly consider this content NSFW. So be careful with your clicking, unless of course you want that person's head to explode that works in HR.

First 10nm Cannon Lake Laptop Spotted Online: Lenovo Ideapad 330 for $449

Intel’s first 10nm processor has debuted in the form of Lenovo’s Ideapad 330, which is now available through certain venues in China. The device is definitely on the lower end, with a 2.2 GHz base clock and no integrated graphics. Some say that Intel’s 10nm is simply disappointing, as it is years late, features fewer cores than originally envisioned, and has clocks that are a regression from 14nm.

It is a 2.2 GHz Dual Core with a boost up to 3.1GHz with no iGPU. That is disgraceful really, and it shows how much of a mess that Intel's 10nm really is. A chip that is two years late has no iGPU, and it can't even surpass 3.5GHz in a 15w package like its 14nm brothers do? (See Kaby Lake R.) That is both uninspiring and disappointing, Intel.

Intel Delays 10nm Cannon Lake Processors Again

Intel has announced they are not going to ship 10nm processors in high volume this year. This move seems to confirm rumors that their 10nm process still isn't up to steam and they need more time to get things right. While I'm all for getting things right I'm also impatient to get my new shiny 10nm processors and I wish Intel would get their act together sooner than later. They better hurry up before their competitors release next generation process processors. You can read the earnings report here.

Intel is on solid footing, in other words, though pesky challenges remain in manufacturing its next-generation 10nm parts. Krzanich acknowledged as much during an earnings call, attributing the delay to difficulties in getting 10nm yields to where they need to be. So rather than push to ship 10nm in volume this year, Intel is giving itself some additional time to sort things out.

Boeing Hit by WannaCry Virus but it Caused Little Damage

Yesterday Boeing was hit with the WannaCry virus (site detects ad blockers) and early reports said it could seriously hamper their ability to produce aircraft. However, the company has stated that little damage was done and they don't expect any production impact at this time. While it's good news that Boeing isn't severely damaged by this attack it's concerning to me that they were even hit by it in the first place. Boeing is a company with significant national security implications and they need to tighten their cybersecurity up. Thanks cageymaru.

"We’ve done a final assessment," said Linda Mills, the head of communications for Boeing Commercial Airplanes. "The vulnerability was limited to a few machines. We deployed software patches. There was no interruption to the 777 jet program or any of our programs."
