For decades China has been the country that supplied the entire world for ridiculous prices. A commercial strategy impossible to match by other countries that has brought them benefits and losses in equal parts. The country is in a brutal reconversion to produce its own technology that competes with the rest of the world. Proof of this is the announcement by Loongson, who has introduced the 3A4000 and 3B4000 processors.

The two processors have 4 cores, although it has not been specified if they have processing threads. The 3A4000 is a processor focused on the consumer market and the 3B4000 is focused on servers. They have also highlighted that these processors are 100% made in China without third-party intellectual property.

New processors made entirely in China

Hu Weiwu, President of Loongson, has indicated that the 3A4000 offers twice the performance of the 3A3000. In two years the company has managed to make a quite remarkable performance leap. According to the data, this new processor for the home market matches a 2015 AMD FX Excavator architecture with 28nm lithography.

These two new processors use the GS464V architecture under ST Microelectronics' 28nm FD-SOI (Fully Depleted Silicon On Insulator) lithography. In addition, these new processors use the FCBGA-1211 socket.

As specified, all the cores work between 1.5GHz and 2.0GHz by means of dynamic frequency by tension. It has 8MB of L3 cache and has a DDR4 @ 2400MHz controller. Something interesting is that the security implemented makes it invulnerable to Meltdown and Specter. And it is that this processor integrates encryption algorithms such as MD5, AAES and SHA. Regarding the TDP, under 1.5GHz it is 30W, at 1.8GHz it has a TDP of 40W and 2.0GHz it has a TDP of 50W.

Loongson has also announced that heavy artillery will arrive in 2021. Next year will come the 3A5000 with 4 cores @ 12nm and the 3C5000 with 16 cores @ 2.5GHz. A huge leap that suggests that China is investing heavily in processors.
