What simply occurred? Chinese language firm Loongson Expertise is busy creating the following technology of its do-it-yourself PC processors. A current social put up seemingly means that growth goes effectively, and Loongson might attain parity with Western x86 CPUs sooner slightly than later.
Chief architect Hu Weiwu began growth of the Loongson chip know-how in 2001, however issues have now change into far more sophisticated due to the sanctions imposed by the US authorities towards Chinese language corporations. Loongson know-how is nevertheless nonetheless making strides – if current info coming from Chinese language social networks are considerably primarily based on precise information.
Final week, Loongson shared a put up on QQ.com detailing the efficiency of its Loongson 3A6000 processor. The brand new CPU is supplied with 4 computing cores working at a 2.5GHz frequency, the corporate said, representing a brand new technology of Loongson tech which was simply efficiently taped out. The corporate confirmed the check outcomes achieved by China Electronics Standardization Institute (CESI), seemingly to supply a “third-party” vibe to its efficiency claims.
CESI seemingly used SPEC CPU 2006, a benchmark instrument designed to emphasize a system’s CPU, reminiscence subsystem and toolchain. The suite was retired in 2018, although, 5 years earlier than the brand new Chinese language exams. In keeping with information offered by Loongson, the 3A6000 CPU scored 43.1/54.6 factors in single-thread mounted/floating level exams, and 155/140 factors in multi-threaded mounted/floating level exams. The processor was capable of ship 42GB/sec bandwidth with DDR4-3200 dual-channel reminiscence modules, whereas Unixbench achieved a rating of 7400 factors.
Loongson states that these outcomes put the 3A6000 quad-core CPU on par with quad-core x86-64 processors launched by Intel three years in the past. In 2020 Intel launched its Comet Lake structure with the Tenth-gen Core CPUs, which included six Core i3 fashions with 4 cores and eight computing threads. After Comet Lake, Intel launch three extra important desktop microarchitectures and is able to ship Meteor Lake, the 14th-gen Core CPUs primarily based on a chiplet design and geared up with a “Imaginative and prescient Processing Unit” to speed up AI hundreds.
Loongson 3A6000 makes use of the brand new LoongArch structure, a poorly documented ISA which was largely derived from MIPS. The RISC-based MIPS structure was developed by the namesake US firm, which retired the know-how in 2021 and adopted the RISC-V structure. Loongson continued MIPS growth after licensing the MIPS32 and MIPS64 architectures in 2011, and LooongArch is speculated to incorporate design decisions derived from each MIPS and RISC-V.
Even when efficiency claims over CPU {hardware} are true, Loongson will seemingly have a harder time on the software program entrance. Linux kernel and working methods nonetheless do not present full help for the LoongArch ISA, and a working Home windows model that would run on the brand new processors is clearly out of the query.
