Chinese CPU developer Loongson officially launched the next-generation 3A5000 CPU based on the company’s proprietary micro-architecture. The company stated that, compared to previous generations, the new processor for client PCs offers up to 50% performance improvement at lower power consumption, which may make it better than CPUs developed by leading designers. Competitive.
The Loongson 3A5000/LS3A5000 processor is a quad-core CPU with a working frequency of 2.30 GHz-2.50 GHz.The cores are superscalar, each core has four general-purpose ALUs and two 256-bit vector operation units, report Science and Technology PostThe kernel is based on the LoongArch GS464V instruction set architecture, Reported to have nearly 2,000 proprietary instructionsIn addition to the basic ISA, LoongArch also supports binary conversion extension instructions (LBT), vector processing extension instructions (LSX), advanced vector processing extension instructions (LASX) and virtualization extension instructions.
In terms of performance, Loongson claims that its 3A5000/LS3A5000 CPU is more than 50% faster than its predecessor LS3A4000 (perhaps when running software designed for LoongArch), and its power consumption has also been reduced by 30%. Remember, LS3A4000 is comparable to AMD’s excavators, and the new LS3A5000 will provide performance close to AMD’s first generation Ryzen. The developer said that when the new CPU is compiled with GCC, the fixed-point and floating-point single-core base score in SPEC CPU2006 is 26+, and the quad-core score is 80+.
In order to reduce power consumption, 3A5000 implements dynamic frequency and dynamic voltage regulation, and can dynamically shut down unused hardware.
The 3A5000 CPU has two DDR4-3200 memory controllers with ECC and four HyperTransport 3.0 controllers with consistency support to achieve SMP (Symmetric Multiprocessing) function. Like all Chinese processors, the Loongson 3A5000 chip supports national encryption standards such as SM2, SM3, and SM4 in hardware.
Loongson previously referred to its next-generation processors as “MIPS64-compatible”, indicating that the new chip can still execute programs designed for the company’s LoongISA architecture, which is a subset of the MIPS64 ISA. At the same time, GCC, LLVM and GoLang compilers already support the LoongArch GS464V instruction set architecture. In addition, multiple virtual machines support ISA.
Loongson’s 3A5000 CPU will be mainly sold to Chinese PC manufacturers, so its pricing is temporarily unknown and hardly disclosed publicly.
