Loongson has made a significant advancement in the tech landscape with the official launch of its next-generation 3C6000 CPUs. Tailored specifically for the domestic server market in China, these processors boast an impressive configuration of up to 64 cores.
Introducing the Loongson 3C6000 Series: A Leap Forward in CPU Technology
After over a year of development, Loongson has unveiled its long-awaited 3C6000 series server CPUs. These innovative chips are set to enhance server performance within China, catering to the needs of domestic consumers and businesses alike.
In its recent announcement, Loongson revealed three new processor families: the 2K3000, 3B6000M, and 3C6000. The earlier two models utilize the LA364E architecture and support up to 8 cores, delivering clock speeds reaching 2.5 GHz. Additionally, the integrated GPU has seen an enhancement from LG100 to LG200, now providing 256 GFLOPs of FP32 compute and 8 TOPS of INT8 performance, making these CPUs well-suited for industrial sectors, kiosks, and mobile terminals.
The crown jewel of this release is undoubtedly the Loongson 3C6000 series, which employs the company’s 4th Generation architecture featuring LA664 cores. This series includes three distinct variants: the “S”series (single chiplet), “D”series (double chiplets), and “Q”series (quad chiplets).Each chiplet houses 16 cores, allowing for varying configurations of 16, 32, and an astonishing 64 cores respectively. These CPUs have clock speeds between 2.0 GHz and 2.2 GHz, and utilize Loongson’s advanced Dragonchain interconnection technology for chiplet scalability.
The 3C6000 series processors come equipped with notable cache specifications, including 64 KB of L1 instruction (L1i) and data (L1d) caches, 256 KB of L2 cache per core, and a shared 32 MB L3 cache. The “S”series is designed with a quad-channel DDR4-3200 controller, while the “D”and “Q”series incorporate an 8-channel DDR4-3200 controller. These models support multi-socket configurations with layouts accommodating up to four sockets. Additionally, the series is equipped with PCIe Gen4 lanes – 64 for the “S”series and 128 for the “D/Q”series – with varying Thermal Design Power (TDP) ratings from 100-120 Watts for “S”to 180-300 Watts for the “D/Q”.
In terms of performance, preliminary benchmarks showcase how the 3C6000 series stacks up against Intel’s 3rd Generation Xeon “Ice Lake-SP”processors. For instance, the LS3C6000/S features 16 cores at a clock speed of 2.2 GHz, which is compared to the Intel Xeon Silver 4314, also a 16-core processor, clocked at 2.4 GHz.
The findings indicate that Loongson’s CPUs excel in integer performance per the SPEC CPU 2017 (GCC15) benchmarks, though their floating-point performance lags slightly behind. As for the 32-core variant, performance gaps close, while the 64-core version running at 2.1 GHz delivers results competitive with the Xeon Platinum 8380 at 2.3 GHz.
The strongest selling points for the Loongson 3C6000 series CPUs are their competitive pricing and availability tailored for the Chinese market. With these processors now available, further performance analytics are anticipated in the upcoming weeks.
