A shocking new discovery about China's successful ability to manufacture 7nm System on Chip in a local factory, based on domestic CPU and GPU architecture.

The technology blogs and "experts" are all in shock, because they had no idea what China was able to produce such advanced SoC like "Huawei's HiSilicon Kirin 9000S" that is powering the company's flagship mobile phone P60 Pro.

Ever since the US started the campaign to sanction and boycott Huawei a few years ago, the company has turned away from using American based products and any technology that could be controlled by the American/Western sanctions.

The impressive (yet not so fast with today's levels) SoC is nothing but a wake up call for the western companies dominating the #CPU, #GPU and #SoC market, from #Intel, to #AMD, #NVidia and of course #Qualcum.

The technology war that the US started, is not going to end well when China manages to create even more efficient and powerful CPUs to power not only expensive mobile phones, but also mid range and low cost ones as well as tablets and ultra portable tablets.

The treatment of #Russia after the War in #Ukraine and how the whole western world tried to isolate and corner Russia was a wake up call for China in so many fronts, and they seems to be making giant leaps rather than baby steps.

Huawei's HiSilicon Kirin 9000S looks to be a quite complex SoC packing four high-performance cores (one at up to 2.62 GHz and two at up to 2,150 MHz) and four energy-efficient cores (up to 1,530 MHz) based on the company's own TaiShan microarchitecture (which still looks to be found on the Armv8a ISA ) as well as the Maleoon 910 graphics processing unit operating at up to 750 MHz, based on screenshots by Huawei Central. CPU and GPU cores run at relatively low clocks compared to frequencies of Arm's cores featured in previous generations of HiSilicon's SoCs.

But low frequencies can be explained by the fact that SMIC makes the new SoC on its unannounced 2nd generation 7nm fabrication process, which could be a breakthrough for #SMIC, Huawei, and China's high-tech industry. Although TechInsights calls this fabrication technology SMIC's 2nd generation production node, state-controlled Global Times claims that China's foundry champion uses its 5nm-class manufacturing technology to make the SoC. But these two names seem to describe the same thing, which was once known as SMIC's N+2.

#Arduino Offers Up Two New #Uno Boards

Source: https://www.tomshardware.com/news/arduino-offers-up-two-new-uno-boards

The $27 Arduino R4 #WiFi sees the familiar Arduino Uno layout but with a slight revamp. The layout remains the same, but instead of a large #Atmel ATMEGA328P dominating the board, we see a 12 x 8 #LED matrix. This matrix is used to show images and scroll text in much the same way as micro:bit. Replacing the 16 MHz ATMEGA328P #microcontroller is a 48 MHz Renesas RA4M1 Arm Cortex-M4 #CPU, providing an on-paper performance boost. How it will be reflected in your projects remains to be seen.

#Arm acknowledges side-channel #attack but denies #Cortex-M is crocked

source: https://www.theregister.com/2023/05/15/mcu_side_channel_attack/

"The Security Extensions for the Armv8-M architecture do not claim to protect against side-channel attacks due to control flow or memory access patterns. Indeed, such attacks are not specific to the Armv8-M architecture; they may apply to any code with secret-dependent control flow or memory access patterns," argued Arm.

#PineTab2 is coming

It*s a #Linux #tablet with #keyboard for $159: https://www.pine64.org/2023/03/01/february-update-things-are-taking-shape/

  • #PineTab will be available in two SKUs: 4GB RAM / 64GB eMMC & 8GB RAM / 128 eMMC
  • #ARM #CPU #Rockchip #RK3566 with four #Cortex-A55
  • Micro #HDMI, 2x USB-C (3.2 & 2.0), MicroSD slot
  • Pricing: 4GB/64GB version USD $159 & 8GB/128GB version $209
  • First impression of the PineTab2 – most refined Linux-capable hardware from #PINE64; very high quality all around and a major step-up from the original
  • PineTab2’s keyboard impressions – very good keyboard, sturdy and hefty stand and solid key backlight
  • PineTab2 software more mature than many of you expect – thanks to the work on Quartz64 and SOQuartz by the community; only a few bits missing
  • #FOSDEM demo ran #DanctNix #Arch + #KDE Plasma Desktop and was well received
  • Launch window – sometime in April, but no promises

Neuer Anlauf, mir einen neuen #Rechner zusammenzustellen :) Mein olles LGA1386-Mainboard mit dem Xeon ist einfach nicht mehr zeitgemäß ;) Obwohl da sogar noch Metrox Exodus einigermaßen flüssig läuft.

Es wird wohl nun doch ein Rechner mit neuen Sockel AM5. Ja, ist echt teuer, aber im Vergleich zu den Gebrauchtwagenpreisen nun doch echt erschwinglich und ich habe mir schon lange keinen neuen Rechner mehr geleistet. Die Grundkomponenten werden vermutlich sein:

#Mainboard: ASUS TUF GAMING X670E-PLUS Wifi, ATX
#CPU: AMD Ryzen 5 7600X

Beim #RAM, da muss ich noch mal gucken. Es werden wohl 2x32GB, also 64GB. Wozu braucht man mehr? Okay, für Chrome vielleicht ;D Aber hoch getaktet darf er sein.

M.2-SSD ... Da gibt es schicke mit PCIe 4.0. Natürlich sind die teurer als PCIe 3.0, aber halt auch (noch) schneller.

Ein Problem ist noch das Gehäuse. Ich bin von der Define-Serie von Fractal Design ja recht angetan, auch wenn ich da auf einen externen 5,25"-Schacht verzichten muss (bislang für DVD und Docking Station genutzt), zumindest bei den etwas kompakteren Gehäusen. Also z. B. das Define 7 Compact, das ist schon recht nett, wenn auch nicht kleiner, als mein bisheriges Gehäuse. Was mich aber echt nervt: USB- und Audio-Buchsen und der Einschaltknopf sind nicht vorne, sondern oben. Das scheint heute bei vielen Gehäusen so zu sein. Man findet zwar auch andere, aber das ist ja nicht das einzige Kriterium. Nun überlege ich, ob ich mich damit anfreunden kann. Am liebsten habe ich den Rechner oben zu, also auch keine Lüftung oben.

AIO-#Wasserkühlung? Ich überlege noch. So viel teurer, als ein Noctua-CPU-Kühler ist das auch nicht und lässt sich beim Define 7 Compact auch in die Front integrieren (anstatt oben), wenn ich das richtig sehe. Spricht etwas gegen eine Wakü? Ich hatte noch nie eine.

Das Problem: Je mehr ich darüber nachdenke, desto unentschlossener bin ich. Zum Beispiel: Muss es der fette Chipsatz sein? Reicht vielleicht auch ein kompakterer µATX-build? Kleinere Rechner sind ja eigentlich fein, aber die Auswahl bei Mainboards und Grafikkarten ist dann schon etwas eingeschränkter.

Meine "olle" Grafikkarte, eine Zotac GTX1060, wird wohl erst mal weiter ihren Dienst tun. Die kann ich später immer noch bequem tauschen.

Wen wer noch Ideen oder Tipps hat, immer her damit. ;)

"Our proprietary #UEFI code appears to have been leaked by a third party. We do not believe this exposes any new security vulnerabilities as we do not rely on obfuscation of information as a security measure. This code is covered under our #bug bounty program within the Project Circuit Breaker campaign, and we encourage any researchers who may identify potential vulnerabilities to bring them our attention through this program. We are reaching out to both customers and the security research community to keep them informed of this situation." — Intel spokesperson.

So why is it not #OpenSource Intel?
