Source 3: RadiatingLight https://linustechtips.com/main/topic/934860-intels-28-core-5ghz-cpu-is-misleading-at-best/

 

• Without taking model names, Intel made it clear that it's launching a new client-segment 28-core/56-thread processor.

• this processor is clocked at 2.70 GHz (nominal), and without revealing Turbo speeds, Intel managed to overclock it bench-stable to 5.00 GHz, at which it scored 7,334 nT Cinebench points.

  • It wasn’t immediately clear to many in the media that the cpu was overclocked

• launch in Q4-2018.

• this CPU was running on intel’s LGA-3647 server platform, which all but confirms that this is just a 28-core Xeon with an unlocked multiplier.

  • The demo setup was cooled by an $850 aquarium chiller which consumes 1200W and is meant to be able to cool 1000L of water

• AMD has announced the next Threadripper CPU, built with their updated 12nm Zeppelin dies.

• AMD’s Zeppelin silicon has 8 cores, and the first generation Threadripper uses two of them to get to the top-SKU of 16-cores.

• Inside the CPU however, there are four pieces of silicon: two active and two inactive.

  • For this second generation of Threadripper AMD is going to make these inactive dies into active ones

• these new processors would have up to 32 cores in total, mirroring the 32-core versions of EPYC.

  • On EPYC however, there are eight memory channels, and AMD’s X399 platform only has support for four channels.

  • the two now ‘active’ parts of the chip do not have direct memory access.

    • This adds latency to the platform, however AMD says that for all but the most memory bound tasks this should not be an issue

• TDP of 250W, up from 180W of the 1950X

• Rumours of an August launch

• No pricing yet.

 

Massive changes to the Steam Store

Source 1: matrix07012 https://linustechtips.com/main/topic/934942-massive-changes-to-the-steam-store-after-the-waifu-holocaust/

Source 2: https://steamcommunity.com/games/593110/announcements/detail/1666776116200553082

 

• Valve has posted a blog post outlining their struggle to regulate what should and should not be allowed in the Steam Store

  • The submission process isn’t automated - groups of people look at the contents of every controversial title submitted to the store

  • people have falsely assumed these decisions are heavily affected by our payment processors, or outside interest groups

• The challenge is that this problem is not simply about whether or not the Steam Store should contain games with adult or violent content. Instead, it's about whether the Store contains games within an entire range of controversial topics - politics, sexuality, racism, gender, violence, identity, and so on.

  • there are controversial topics that are particular to games - like what even constitutes a "game", or what level of quality is appropriate before something can be released.

• What did they decide in the end?

  • Valve shouldn't be the ones deciding.

    • If you're a player, Valve shouldn't be choosing for you what content you can or can't buy.

    • If you're a developer, Valve shouldn't be choosing what content you're allowed to create.

    • Valve’s role should be to provide systems and tools to support your efforts to make these choices for yourself, and to help you do it in a way that makes you feel comfortable.

  • They’ve decided that the right approach is to allow everything onto the Steam Store, except for things that are illegal, or straight up trolling.

• This allows Valve to focus more on building tools to give people control over what kinds of content they see.

  • Current tools, but are too hidden and not nearly comprehensive enough.

  • They’re going to enable you to override the recommendation algorithms and hide games containing topics you're not interested in.

    • So if you don't want to see anime games on your Store, you'll be able to make that choice.

    • If you want more options to control exactly what kinds of games your kids see when they browse the Store, you'll be able to do that.

  • developers who build controversial content shouldn't have to deal with harassment because their game exists, and we'll be building tools and options to support them too.

• They’re going to push developers to further disclose any potentially problematic content in their games during the submission process, and cease doing business with any of them that refuse to do so honestly.

• So what does this mean?

  • The Steam Store is going to contain something that you hate, and don't think should exist.

  • But you're also going to see something on the Store that you believe should be there, and some other people will hate it and want it not to exist.

  • Some people at Valve will agree with you. Others won’t.

  • The games allowed onto the Store will not be a reflection of Valve’s values, beyond a simple belief that you all have the right to create & consume the content you choose.

• “We believe you should be able to express yourself like everyone else, and to find others who want to play your game. But that's it. “

Source 2: https://www.tweaktown.com/news/62147/amd-unveils-worlds-first-gpu-7nm-computex-2018/index.html

 

• At Computex, AMD annouced the first 7nm GPU, launching in 2H 2018.

• AMD will have Vega on 7nm inside of the upcoming new Radeon Instinct part

  • 35% more performance over the previous-gen 14nm part,

  • twice the power efficiency

  • 2x density means smaller die sizes or bigger GPUs.

• This now means AMD is ahead of the GPU game in one area, as even Volta is only on 12nm.

• DISCLAIMER: Due to various marketing and discrepancies among foundries, the number itself has lost the exact meaning it once held.

  • Recent technology nodes such as 22 nm, 16 nm, 14 nm, and 10 nm refer purely to a specific generation of chips made in a particular technology.

  • It does not correspond to any gate length or half pitch.

• At Computex, Gagabyte announced that it’s getting into the RAM business...as well as the faux-RAM business.

• Gigabyte is selling its new AORUS RGB LED memory as a kit.

  • Two of the sticks are 16GB (2 x 8GB) of DDR4 memory,

  • but the other half of the bundle is two faux-RAM sticks that are made of the same aluminum housing with LEDs that can sync up with the actual RAM sticks. But they have none of the functional memory bits.

• Gigabyte is also exploring the possibility of just selling the dummy sticks separately one day.

• Seasonic have come up with a new cable management system for those who despise case clutter.

  • System Cable Management Device

• It’s essentially a power bar that stands vertically against the case’s motherboard tray. Cables from the PSU plug into the bottom, and then the rest of the system’s cables plug in along the bar

  • connect the cabling you require, and leave out any you don’t need.

• It’s thin enough to fit behind your motherboard, hiding almost all of your wiring and also ensuring you do not have to stretch that additional motherboard power cable.

• Seasonic claims that introducing the SCMD into your power loop will only drop efficiency by 1% overall

• Will come in 3 sizes

• No price or launch date

 

150k projects ditch GitHub following Microsoft Acquisition

Source 2: https://motherboard.vice.com/en_us/article/ywen8x/13000-projects-ditched-github-for-gitlab-monday-morning

 

• On Monday morning, Microsoft announced that it had acquired the popular collaborative software development platform GitHub for $7.5 billion in Microsoft stock.

• While some saw the acquisition as the only way to sustain a free platform that had grown as large as GitHub, others saw it as the death knell for a neutral, community-driven platform that was the de facto home of open source software development.

• After the announcement, thousands of GitHub projects were migrated to competing platform GitLab

  • Over 150,000 projects have moved to GitLab now

  • There are around 80 million projects hosted on GitHub

• GitLab use an open core model, where a limited version of its software is free and open source, and a more expansive version of its is available on a paid-subscription model.

• But how Microsoft will address

  • projects on GitHub that directly undermine its own services, such as this emulator for running Xbox games on Windows computers.

  • projects that can be used to directly harm others, such as DeepFakes

 

Apple Deprecating OpenGL

Source 2: https://www.pcgamer.com/developers-fear-for-mac-gaming-as-apple-deprecates-opengl-support/

Source 3: https://developer.apple.com/macos/whats-new/

 

• Apple is deprecating support for OpenGL and OpenCL with the release of macOS 10.14

  • That means it will continue to work, but will not be supported moving forward and could break.

• Apple recommends:

  • “Games and graphics-intensive apps that use OpenGL should now adopt Metal. Similarly, apps that use OpenCL for computational tasks should now adopt Metal and Metal Performance Shaders."

• Apple introduced Metal, its proprietary low-level 3D graphics API, in 2014.

  • every game and 3D application designed for Macs before 2004 uses OpenGL.

  • Many games and apps continue to use OpenGL, since it’s open-source and cross-platform (thus, developers can re-use the same code).

• Apple has supported OpenGL since the late 90's.

• Apple does not officially support the Vulkan API on macOS

• Developers worry that it’s not worth it to port their code to Metal

• It's not clear at this point if Apple will completely remove OpenGL support from a future macOS release, or if the company is simply pushing developers to adopt its Metal API without real plans to end OpenGL support.

 

Pixel 3 Leaks

• The latest leaks indicate that Google is working on not two but THREE version of the Pixel 3

• The third Pixel is likely to be a “mid-range” based on Qualcomm’s new Snapdragon 710 chipset (which promises performance close to 2017’s flagship Snapdragon 835)

• A midrange Pixel 3 delivering clean, stock Android and instant updates at a bargain price would effectively resurrect the role played by much-loved Nexus range.

  • It also would give Google a weapon to counter the budget iPhone X which Apple will launch in September.

• An affordable Pixel 3 is likely to be a gamechanger for midrange smartphone photography.

  • Pixels deliver class-leading results primarily through unique software, not cutting-edge hardware.

• Pixel 3 XL will have a notch and chin-bar with forward facing stereo speakers

• Why doesn’t the Pixel 3 have a notch?

 

Amazon return policy abusers sentenced to nearly six years in prison

Source 2:

 

• Three individuals have just received lengthy prison sentences for their involvement in a scam that defrauded Amazon out of $1.2 million.

• For two years, the Finans ordered over 2,700 electronic items from Amazon including GoPro digital cameras, Xboxes, smartwatches, tablets and laptops and then reported them as damaged.

• Once Amazon replaced the products, they would sell them to a third person -- Danijel Glumac -- who then sold them to a buyer in New York.

• In all, Erin and Leah Finan  are said to have made around $750,000 running the scam while Glumac made approximately $500,000.

  • How do those numbers work?

• Erin and Leah Finan received 71- and 68-month sentences, respectively while Glumac was sentenced to 24 months in prison

• "Consumer fraud not only unjustly enriches the perpetrator, it causes all of us to pay higher retail prices," US Attorney Josh Minkler said in a statement. "To those who seek to exploit the convenience of online shopping through fraud, remember this case. You will be caught. You will be prosecuted. And you will go to federal prison for a long time."

• The Finans created hundreds of false identities and fake accounts in order to pull off their scheme.

  • Alongside their Amazon fraud, they also bounced checks, rented cars and failed to pay for them, sold other stolen high-end goods and withheld rent -- actions that were taken into account during sentencing.

• The three defendants have been ordered to pay $1,218,504 in restitution.

 

Australian gamers blamed for slow internet

Source 1: RX7970 https://linustechtips.com/main/topic/935481-australian-gamers-blamed-for-slow-internet/

Source 2: http://www.abc.net.au/triplej/programs/hack/nbn-blaming-gamers-for-slow-speeds-contradicts-own-advice/9836492

 

• Australia’s National Broadband Network's (NBN) CEO has blamed gamers for slow speeds in parts of the network, saying they're using up too much data.

• Bill Morrow appeared before a parliamentary committee to discuss how the NBN was being rolled out in regional Australia.

  • He said his company had seen a significant increase in data consumption on its fixed wireless network  

  • this is a relatively small part of the national network set aside for premises that aren't connected to the fibre of copper network.

  • It will use radio signals and transmission towers spread across the country to connect about 600,000 thousand premises.

• The CEO said the company was considering throttling back data consumption of "extreme users" during peak periods.

  • When asked what an "extreme user" was, he replied  "It's gamers predominantly, on fixed wireless."

• In Dec 2016, the NBN wrote:

  • "Where streaming 4K video can use as much as 7 gigabytes (GB) per hour and high-quality audio streaming gets up to around 125 megabytes (MB) per hour, (but usually sits at around half that) certain online games use as little as 10MB per hour."

• Last March, NBN data showed the average household connected to the NBN was churning through 32 per cent more data compared to the previous year.

  • They said the reason for this was launch of Netflix in Australia in March 2015

• Morrow may be scapegoating gamers because the alternative is admitting that the network can’t accommodate the new most common use-case: video streaming.

  • One forum comment says this is out of context: what Morrow really meant was “the type of people who game are the type who consume a lot”

 

Organic carbon molecules found on Mars

Source 2: https://www.space.com/40819-mars-methane-organics-curiosity-rover.html

 

• NASA's Mars rover Curiosity has identified a variety of organic molecules, the carbon-based building blocks of life as we know it, in 3.5-billion-year-old rocks on Mars.

• This does not give us any evidence of life

• "But there is a possibility that [the organics] are from an ancient life source; we just don't know,"

• Another finding: that methane concentrations in Mars' atmosphere cycle seasonally.

  • The discovery suggests that the gas is seeping out from underground reservoirs

    • It is POSSIBLE that some of the methane was produced by organisms, as it it here on Earth.

I got the notification after you were no longer live, and I'm not the only one judging by twitch chat

New idea, a dedicated twitter or RSS feed that's only "we're going live" on the wan show since you're never on time. Youtube notifications and twitch email suck.

Regarding the claim that there's no industry standard way of measuring the transistor size, unfortunately there is. 7 nm is the channel length, literally the length between source and drain and there's nothing more to it, it's not a square area, it's universal and finite description, just like W/L ratio of a transistor. 

And based around this (actually the lambda number of the process to be precise) you have to scale the transistors and other devices accordingly.

 

Fair enough the length of the gate channel isn't the only parameter that dictates the size of a VLSI device, in fact it's importance has somewhat dropped over the years, as we're reaching just a couple of atom layers in the gate length (bear in mind a silicon atom is just 0.2 nm big), the battle is now more on the area around a singular transistor, and the density at which you can pack those devices on the silicon wafer. And some of those you can't easily change, like making thinner metal interconnects is hard, if you go over a given current density you'll just evaporate (electromigrate) your traces. 

 

Can't really find the nice table how different small parts of a VLSI changed in size over the years, which illustrated how aggressive was the channel length scaling compared to other features (gate area? source and drain areas? pads? polySi?), but there's some other cool thing to show. The pitches of elements.

 

Intel press materials actually do a fair job at illustrating this, look here at page 2 for example. https://newsroom.intel.com/newsroom/wp-content/uploads/sites/11/2017/09/10-nm-icf-fact-sheet.pdf 

While i wouldn't take facts seriously (they pull some funnies in those, like the actual transistors per area is about doubled compared to RL scenarios), the graphics are on point. So nowadays even if the transistor length doesn't change drastically, there's a lot going on around it that does. 

Here's one with a bit more of eyecandy https://newsroom.intel.com/newsroom/wp-content/uploads/sites/11/2017/03/Ruth-Brain-2017-Manufacturing.pdf intel releases quite a bunch of electron microscope photos that illustrate the little details around this.

 

But TL;DR channel length is standard, it's the size of other components and spacing, which isn't advertised that much that tells the whole story.
