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 (3C5000L) 16-core server processor clocked at up to 2.5 GHz is now official and is apparently comprised of four LS3A5000 (3A5000) 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. The processor also includes two 64-bit DDR4-3200 controllers with ECC checksum support, as well as four HyperTransport 3.0 controllers with multi-processor data consistency support.
Performance-wise, Loongson 3A5000 is said to achieve 26+ points in the single-core and floating-point SPEC CPU2006 benchmarks, and over 80 in the multi-core version of the benchmarks. 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. The SoC also embeds hardware security with a secure and trusted module, and an SM2/3/4 crypto engine with a performance of more than 5Gbps, as well as support for other crypto algorithms.
