  • Even on ideal conditions (close to the Equator, no clouds) like in Northeast Brazil, you only get 5.5 to 6.0 kWh/m^2 of Solar energy, which means the roof of a small car, with 1 m^2 of solar panels, would only generate that amount of electricity if they were 100% efficient. That’s just 10% of the battery capacity of a small EV, like a BYD Dolphin.

    My point is, even if solar panels doubled their efficiency, they would still only capture about half the energy of the Sun (currently, the best panels are at 24% efficiency), which means only about 2.5 to 3.0 kWh per day.





  • Taiwan, not PRC. Mainland China isn’t capable of making CPUs and GPUs whith the performance and low power draw needed for a portable console in the volumes necessary. They brute-forced their way into a 7nm process, but it’s expensive and low yields, so they’re using it only for crypto mining ASICs and Huawei phones.

    To make a console like the Steam Deck, they would need an AMD64 chip on 5nm. Granted, Zhaoxin does have a licence for X86 architecture (inherited from Via, who got it when they bought Cirix), but they’re still far from being able to make those in 7 or 5nm.

    Meanwhile, TSMC in Taiwain is already shipping 3nm chips for Apple and soon for AMD too.

    Unless China figures out Extreme UV, like in the ASML machines, or direct stamping, like in recently announced Canon machines, they won’t be competitive with Intel, TSMC or Samsung anytime soon.





  • Which means several years of development ahead to have working silicon, and that would mean AMD64 v1, which Windows and many libraries/application in Linux doesn’t support anymore.

    In Debian Unstable, for example, ld-linux-x86-64.so.2 reports that it only supports v2, v3 and v4. v3 architecture , so CPUs from Buldozer/Nehalen generation or later. That version of the architecture will still be protected for a few more years.

    Since both Intel and AMD are competitors on both CPU and GPU markets, Nvidia’s only option is Zhaoxin, a joint venture between Via Technologies (who has a license for box X86 and AMD64) and Shanghai municipality.

    Failing that, they would have to go with ARM and emulation, which would come with a performance penalty, or separate CPU and GPU chips, which would make the devices bigger and less power efficient than competing models with APUs.

    In conclusion, don’t hold your breath. This talk about Nvidia handheld PCs is just to appease their shareholders and create FUD on AMD and Intel ones.




  • That might be true inside Russia, but not in the rest of the world. F5 could sue in the US and force the registrar responsible for the .org TLD to hand the domain to them.

    In his place, I would chosen something related but different enough to avoid trademark infringement, like “Freeginx”. IANAL, but I believe sometimes all it takes is one letter to keep lawyers away.
