Loongson’s first LoongArch processors – 3A5000 for computers, 3C5000L for servers

Loongson has officially launched the first processors based on LoongArch CPU instruction set architecture designed for made-in-China SoCs without the need to license technology made outside of China. Loongsoon LS3C5000L 16-core server processor clocked at up to 2.5 GHz is now official and is apparently comprised of four LS3A5000 LoongArch processors designed for desktop computers and laptops. CnTechPost reports Loongson 3A5000 quad-core 64-bit GS464V processor runs at 2.3GHz-2.5GHz. GS464V microarchitecture comes with four fixed-point units, two 256-bit vector operations units, and two access memory units. That's about 50 percent higher performance than the previous pin-compatible Loongson 3A4000 processor, and the company also claims 30 percent lower power consumption. NET. As previously reported, Loongson also implemented Arm and x86 binary translation, so Windows and Android should also be supported. ITHome wrote both about 3A5000 and 3C5000L, a 16-core LoongArch server processor that integrates four 3A5000 processors, and archives more than 900 points in SPEC CPU2006 performance score when used in a server with four 3C500L processors. It was clear that LoongArch was designed in response to US sanctions against Chinese companies, but just in case there were any doubts that the initiative was political, instead of serving a technological purpose, Loongson 3A5000 is codenamed "KMYC70" to "Commemorate the 70th anniversary of the War of Resist US Aggression and Aid Korea", while Loongson 3C5000's codename is "CPC100" to celebrate the 100th anniversary of the founding of the Chinese communist party.
