I will just say that people inside China that are talking to people in the industry are operating under the belief that SMIC can get to 5nm without EUV and then 3nm will require EUV

i remember SMIC said in 2020, we have completed 5nm and 3nm R&D and awaiting EUV machine. i believe, SMIC will go maximum 5nm with DUVi. for below 5nm they will use EUV..

Some early benchmarks. The zhaoxin k7000 may be the most powerful "domestic" pc chip. The advantage is that it runs x86 application and games at full speed. I feel loongson is a competent processor but it just seems everyone on billibilli are running apps thru wine and binary emulation, even game emulators rather than trying to get those "open source" programs to be compiled into loongarch.

Judging from the test, the same-frequency performance of CPUZ reaches 110 points/GHz, which is not far from the 10th generation Core at 120 points/GHz. The CPUZ single-core performance is about 400 points, close to the i5-10400, and the CPUZ multi-core performance is also close to the i5-10400, about the same as the I7-10750H, and more than 2 times higher than the KX-6780A.



As for the Loongson 3A6000, it is the 10th generation Core i3-10100F with 4 cores and 8 threads, while the i5-10400 and I7-10750H are stronger than the i3-10100F. So it is obvious that this time the KX7000 is stronger than the Loongson 3A6000.

Has there been confirmation as to what node process and where it is fabbed at, as of yet.

US suddenly realizes the importance of mature tech and legacy chips where 14nm and above take over 90% of the market. That's the real battle,
US now switched to pressuring ASML not to sell the 1980Di , the most basic model.

They suddenly realized their major remaining players, like Texas Instruments, work with legacy nodes. Global Foundries is also stuck at 14nm. Intel and Micron still haven't switched to EUV either. This is just pure protectionism.

For whatever reason the world's largest consumer market for semiconductors is expected to continue buying chips from them indefinitely. Good luck with that.

Anyone knows what does SMIC new fab planned operation first quarter 2024 at Lingang made? Is this part of its 28nm expansion?
Click to expand...
Yes. It is one of SMIC's three new 100k wpm 28nm giga fabs.

how its measly N1 fab can support Huawei and Loongson combined huge volume?? No way.

70k wpm with 14nm FinFET isn't "measly". It is larger than the GlobalFoundries plant which used to make chips for AMD.
Of course there is a question of how many 7nm wafers it can make. How much of the originally planned capacity is actually online. And without knowing the yields it is hard to know the real production capacity.

maybe Huawei has its own network for producing chips.

If they have it this is likely with older processes or specialized processes which no one else is interested in doing.
