It is no secret that China is trying to be a 100% technologically independent country, so it invested $ 29 billion to take its microprocessor production to a whole new level! In fact, if you don't know, the country has planned to replace all foreign technology in use in its institutions and public infrastructures, with 'Made in China' solutions by 2022.
If you do not understand what we mean, with this bet, we are talking about removing everything that is Intel, AMD, NVIDIA, Samsung, Microsoft, etc … From the country's infrastructures. Therefore, it is necessary to create processors, RAM chips, graphics cards, among many other things. So, although there is still some time until 2022, it seems that we already have a Chinese processor capable of causing some sweat to Intel and AMD, the Zhaoxin x86!
Zhaoxin x86: Make way for Chinese processors!
Therefore, the Zhaoxin KaiXian KX-U6780A is not something that you can simply buy outside of Chinese territory. Still, it is a product that shows us the potential of ‘made in China’ products, although it is not yet capable of rivaling the big ones in the industry.
What we are going to focus on here is not the current performance … but the degree of evolution of this Chinese industry. Especially when we take into account, which is a CPU produced by a company that most likely never heard of.
Well, we are talking about an 8-core CPU, based on the LuJiaZui architecture, which is not even the fastest offer from Zhaoxin. To get a sense of how this Chinese company got here, we are talking about 9000 months of work by the engineering team, thanks to a simulation that put 4000 cores against various types of software, a job that required 200 TB of data .
Interestingly, in the past, Zhaoxin has stated that the performance of this processor is quite similar to the Intel Core i5-7400 (Kaby Lake), originally launched in 2017. Something later (more or less) confirmed by a benchmark, despite the IPC seeming a little lower
Meanwhile, the KaiXian KX-U6780A reappeared on the Internet, in the Geekbench database, with a single-core score of 363 points, and a multi-core score of 2091 (the i5-7400 achieves 884 and 2793, respectively).
In other words, based on TSMC's 16nm FinFET process, this CPU already manages to reach 2.7 GHz, with a TDP of 70W. Which is comparable to the 65W TDP on the i5-7400. However, it does not have an L3 cache, and is also slightly less efficient.
In short, the Chinese processor still does not reach the heels of what Intel launched in 2017! However… it shows that China is evolving at a breakneck pace! Now see the comparison of the Tom’s Hardware website, which managed to get its hands on a copy.
First of all, we have to say that this processor does not yet have any of the ‘cool’ technologies from Intel and AMD, in the form of SMT / Hyper-Threading or ‘Boost’ capabilities. In other words, we have 8 cores, 8 threads, and 2.7 GHz… None of this changes.
In addition, we have 16 PCIe 3.0 lanes and still support a maximum of 64GB of DDR4-2666 RAM. We also have a GPU with support for DirectX 11, OpenCL 1.1, etc … But it presents a performance in game far below what Intel offers with the Intel HD 630 iGPU in the i5-7400. (20FPS vs 120FPS on Dota 2)
There are other tests in the Tom’s Hardware article that you can read on here. But to finish all of this, Zhaoxin is not yet in a strong enough position to rival AMD or Intel. Still, we have to point out the rapid progress of the Chinese company, which is already planning to jump to 7nm or 5nm in 2021, while also betting on PCIe 4.0 and DDR5 RAM.

Since I was very young I became interested in computers and technology in general, I had my first PC at 10 and at 15 I built my first tower, since then I never stopped. Whatever technology is, I'm in the front row to find out more.
