A800 might still be a competitive chip in both 2023 and 2024 but probably would be obsoleted by 2025. The question is what are these Chinese giants are going to do by then. Are they even actively seeking and improving domestic alternatives to replace Nvidia chips.

Given the explosive demand for ai chips it should surprise no one that companies that have invested a lot into cuda needs more Nvidia gpus. A lot of people interpret this as china needing Nvidia and can't live without it. When reality is that these companies need Nvidia right now because they will fall behind the ai race to Huawei if they don't keep buying Nvidia gpus .

Longer term, you probably end up with a cuda vs ascend battle in china.

Whoever figures how out to reduce the cost will win this industrial race. It’s not who has an early lead but who can sustain the pace.
Exactly so. One of the greatest advantages China has in pursuing SSMB EUV light sources beyond the intrinsic superiority of this technology over LPP is that no one else has the business model. ASML is not going to build and ship synchrotrons. China is unique in having the political will, the fiscal heft, the scientific establishment, and the sheer market size to bring this technology to fruition and achieve its economies of scale.

Taiwan, Japan, Korea et al. are the Myspaces and Research in Motions. They got there first. We'll see who's here last.

...because of premature self-defeatist attitude like this:

No one will buy a CPU with top speed of 2.5 G.
Why Huawei didn't see this coming?
Because Huawei preferred Western products and was avoiding local alternatives. Huawei founder Ren Zhenfei would buy iPhones as gifts for his family over Huawei phones because of the prestige ,values and the admirations he had for US and Canada. Hopefully the family attitudes have moved on from the sanctions and kidnapping.

Imagine if Tim Cook handed out Samsung or Huawei phones to Apple employees lmao. That's how laughable this is. Sad as it was, Meng Wanzhou getting kidnapped by some regime was necessary to wake them up.

Huawei campus in DongGuan. Yes, a fake European city with zero Chinese cultural presence. Thanks to comrade Trump, Huawei went from being totally cringy to based really fast. It just took a kidnapping.

Instead of capitalizing the Chinese market to try at least to regain lost market share the Japanese goverment decided instead to kiss the dirt tainted shoes of the China Hawks and think tankers in D.C. Good to see that the Japanese goverment has such regard for their own country companies.

Nikon sold only 6 photolithography machines in the second quarter, a year-on-year drop of 60%!​


In terms of product sales, Nikon’s global sales of anti-digital cameras in the second quarter increased by 10% from the same period last year to 220,000 units, and sales of replacement lenses fell by 3% year-on-year to 330,000 units; Nikon’s semiconductor lithography equipment in the second quarter The sales volume was only 4 units, only half of the same period last year (8 units), and the sales volume of FPD lithography equipment was only 2 units, far lower than the 7 units in the same period last year. That is to say, throughout the second quarter, Nikon only sold 6 lithography machines, a drop of 60% compared to 15 in the same period last year.

Time value of money means private businesses are intrinsically short-sighted. When entrepreneurs or CEOs talk about a company's "long-term strategic vision" they are bullshittinng you. Even the largest private companies do not plan in detail beyond 5 years or so. Entities whose sole purpose is profit will always prioritize money sooner over money later, no matter the social cost or even the cost to their future selves beyond their planning horizon. This is true no matter the country, [private] company, or culture.

Sai Micro has received trial production orders for micro vibration mirrors which are core components for Laser beam manipulation in Lidars & Laser displays in the field such as cars and AR/VR

Please, Log in or Register to view URLs content!
Keep in mind that Sai Micro signed deal back in April 2022 with a well known Lidar company to produce micro mirrors

The core beam steering element of MEMS Lidar is micro vibration mirror. By fabbing it in 8-inch production line, this can dramatically reduce the cost & volume of solid state Lidars

Back in Dec 2021, Sai Micro still said the difficulty level of micro vibration mirrors is high and they have not achieved mass production

Back a year ago, sai micro says they are still developing the process for making micro vibration mirrors

So, looks like another technical hurdle has been met by domestic chipmaking leader in MEMS

中科融合 developed high precision MEMS micro vibrating chips that can replace TI DLP chips

so you see, even though Chinese companies like robosense & Hesai produce Lidars, they still need domestic companies that can design the core chips in there and fab them to complete the supply chain

Another possibility is Robosense (速腾聚创)

interesting. Could be designed by 希景科技 and fabbed by sai micro. I need to look further into this
