• Huawei's new Kirin 9050 Pro is being called its "most powerful" all-Chinese chip tech giant has ever made

  • Huawei is claiming a 55% density gain by 'folding' its chip in half and stacking it instead of shrinking the actual die

  • The chip still uses US hardware and foreign technology to manufacture, including ASML scanners and pre-2022 Applied Materials and Lam Research equipment

The LogicFolding design is really interesting. I'm eager to see benchmarks to confirm the performance improvements. If it pans out, they have opened a whole new avenue of chip design beyond the diminishing returns of Moore's law.

LogicFolding splits logic across two active silicon layers bonded face to face, with roughly 50 million vertical interconnects at a pitch of about 1.5 micrometers. Because signals travel shorter distances, Huawei says it could lower operating voltage while raising density.

That's a lot of interconnects!

    I had always assumed the flat approach was done due to heatsink requirements. I expect strong performance from their approach but I'm far more interested to see operating temperature under load since that will impact lifespan of the chip. Reducing power loss (presumably with the lower voltage) may balance that out effectively
