Author: EIS Release Date: Feb 28, 2020

Loongson, formerly known as Godson, the China CPU designer, says it has made CPUs that use no third party IP.

 

Loongson’s latest quad-core 3A4000 and 3B4000 processors are claimed to have equivalent performance to AMD’s 2015-vintage 28nm Excavator processors.

 

Both chips have the GS464V microarchitecture,  are made on ST’s 28nm FD-SOI process and come in the FCBGA-1211 package.

 

They each have  8MB of L3 cache and operate at 1.8 GHz to 2 GHz.

 

They support DDR4-2400 memory, dynamic frequency and voltage regulation.

 

The 3A4000 draws up to 30W, 40W and 50W at 1.5 GHz, 1.8 GHz and 2 GHz, respectively.

 

Next year, Loongson plans to launch quad-core 3A5000 and 16-core 3C5000 processors made on a 12nm process operating at up to 2.5 GHz.
