The difference between Zhaoxin and Loongson

Speaking of domestic chips, I think Many netizens feel very bitter in their hearts because they have been calling for it for who knows how many years, but it has never been used on a large scale, and it is difficult to find it in reality. The only one that can compete now is Huawei Kirin in mobile phone processors. As for the PC field, whether it is the prestigious Loongson or Zhaoxin, it seems that they cannot compete with Intel and AMD, and they are lagging behind by N years.

So in the PC field, who is stronger, Loongson or Zhaoxin? What level is it equivalent to Intel? Let’s analyze it today.

　Let’s talk about Loongson first. CurrentlyLoongson’s strongest processor is the Loongson 3A3000/3B3000 series. As can be seen from the official website, this chip is a 64-bit, 4-core design. Using 28nm process, the main frequency is about 1.5GHz.

The three-level shared cache is 8MB, 4*4CM in size, and has 1.2 billion transistors. And we know that Kirin 980 has 6.9 billion units, the size is less than 4*4CM, and it has 8 cores. It can be seen that Loongson is far behind Kirin.

Let’s talk about the gap with Intel. According to the parameters and actual online test data, it is similar to the Intel Core 2 Duo E8600 launched by Intel in 2008. Although this processor is dual-core, the 3.3GHz As for the main frequency, everyone knows that in the PC field, the main frequency has a great relationship with performance. Moreover, Loongson does not use the X86 architecture and cannot install Windows.

Look at Zhaoxin. Zhaoxin is better because it has obtained the X86 authorization, which can be used to install windows systems. This may be One of the biggest advantages is that after all, the current share of windows in China reaches more than 90%.

In addition, the latest Zhaoxin is KX-U5680, 64-bit, 8 cores, 28nm process, main frequency is 2.0GHz, 8M L2 cache, supports 4K, size is 37.5mm x 37.5mm, which is better than Loongson smaller.

Judging from the parameters, it is pretty good. It is roughly the same as the i5 launched by Intel in 2012, which took about 6 years to complete.

It can be seen that if

only looks at the performance of the chip, Zhaoxin is indeed better, and the technology seems to be more advanced, but you must know that Zhaoxin is developed using X86 authorization, and Loongson It uses its own GS464E architecture, so in theory Loongson has a higher technological content.

So to really compare, we can only say that both are more than 5 years behind Intel, and at the same time they have taken the step from 0 to 1. step. But the progress is really not ideal. After all, there is Huawei HiSilicon for comparison!
