  • Most of the Ryzen 4000 laptops announced so far have used H and HS series chips - 45 and 35W parts.  The new Zenbook 14 uses the 15W 8 core Ryzen 4700U.  (Tom's Hardware)

    It pairs the chip with 16GB of LPDDR4X RAM at 4266MHz, which should unlock the power of the integrated graphics....  And also has an Nvidia MX350 with 2GB of 7GHz GDDR5 on a 64-bit bus.  Which means that the dedicated graphics actually have less memory bandwidth than the integrated graphics, which has to be first.

    Specs for the rest of the laptop have yet to be announced.  Or leak, whichever.


  • A look at a fake Intel quad 10GbE network card.  (Serve the Home)

    Apart from not actually being built by Intel, it works perfectly.


  • How will tech hubs weather the pandemic?  (Tech Crunch)

    With any luck by sinking into the ocean, never to be heard from again.


  • A look inside AMD's Am2901 bit-slice CPU.  (Righto)

    Back before you could fit 300 million transisters into a single square millimetre, you might have only been able to build a 4-bit CPU at a reasonable price.  The Am2901 was a 4-bit CPU.  But if you wired two of them together, it became an eight-bit CPU, and if you wired eight of them together you had yourself a 32-bit CPU, albeit a rather slow one because of the external carry propagation.

    Despite that - and the complexity of building a real-world 32-bit CPU out of MSI parts - it saw adoption in many places where a full custom design was too expensive and standard logic too bulky: The famous Xerox Star workstation, computers onboard the F16C/D, and later models of the VAX-11 before the introduction of the VLSI-based MicroVAX.

2 You could try Microsoft Office Lens.  At least it probably won't steal your kidneys.

Apple pies are delicious. But never mind apple pies. What colour is a green orange?
