Haswell is actually not an ancient core, lot's of the tech used in Haswell is still relevant today. Fuck, it took RiscV years until they had anything comparable to Haswell's SIMD.
I replied to you with this account.
I would also like to note that the FIRST comment I made with that acc was in defense of China. EDIT: I deleted it actually but I was defending against the Xinjiang bullshit
Their core designs are more or less way behind, because they needed to learn and create lots of infrastructure technology. Read the Chips and Cheese article on the latest Loongson cores, even tho they have impressive technology in some aspects, the core design is way behind AMD or even Intel.
Zhaoxin is also a bad joke.
Kirin in particular is ARM based and they at least have access to ARM core designs, so it's a surely better situation than fully domestic projects. But still, more single core performance is incredibly hard to achieve, and don't be surprised to learn that these CPUs are only capable of simple tasks.
I'm an Iranian computer engineer and a ProleWiki contributor. I'm not coming from a place of malice, I'm stating the facts of the matter on Chinese technology.
