Chinese language CPU Maker Debuts 32-Core Chiplet-Primarily based Processor
Constructing giant monolithic many-core CPUs is extraordinarily onerous even for famend chip designers. For Chinese language CPU builders, a lot of whom wouldn’t have entry to modern manufacturing nodes, the one approach to construct a processor with excessive core rely is to undertake a chiplet design. Because it seems, that is precisely what Chinese language CPU maker Loongson does with its 32-core 3D5000 processor, Sina reviews.
Earlier this 12 months Loongson started to ship its 3C5000 processor that depends on 16 LA464 cores that includes the corporate’s LoongArch microarchitecture, as much as 64MB of cache, and 4 64-bit DDR4-3200 reminiscence interfaces with ECC help. The Loongson 3D5000 takes two 3C5000 CPUs and locations it on a single piece of substrate to construct a 32-core processor with eight reminiscence channels. The 32-core processor helps as much as 4-way simultaneous multiprocessor configurations and subsequently it’s potential to construct a server with as much as 128 cores.
Loongson lately accomplished verification of its 3D5000 processor, the report says. The CPU reportedly consumes 130W at 2.0 GHz in addition to 170W at 2.20 GHz. Loongson’s 3D5000 CPU is available in an LGA-4129 packaging.
Whereas constructing a 32-core CPU based mostly on a proprietary microarchitecture is an achievement, it ought to be famous that product is a approach to check capability to construct a chiplet-based design. Whereas China-based SMIC — which produces processors for Loongson — slowly adopts extra superior nodes, it’s considerably behind market chief TSMC. Due to this fact, firms like Loongson can’t provide merchandise which might be corresponding to these from AMD and Intel.
Chiplets signify an actual alternative for Loongson to construct relatively severe processors and servers platforms with important variety of cores and proprietary microarchitecture enhanced for servers and supercomputers. In the meantime, we do not know whether or not different CPU builders from China will observe the swimsuit.
In the case of efficiency, Loongson says that its 32-core 3D5000 CPU scores 400 factors within the SPEC CPU2006 base check, whereas the results of a 2-way 32-core 3D5000-based machine exceeded 800 factors within the SPEC CPU2006 base benchmark. The CPU designer believes {that a} 4-way machine will hit 1600 factors.
Loongson is gearing as much as ship samples of its 32-core processors within the first half of 2023, whereas industrial variations will likely be shipped later.
