Loongson has officially launched its next-gen 3C6000 CPUs, featuring up to 64 cores for China's domestic server market segment.
China Gets Next-Gen 64-Core CPUs With Loongson's 3C6000 Series, Built For Servers With Up To Four Chiplets
It's been over a year since Loongson taped out its next-gen 3C6000 series server CPUs. These new chips are designed for China's server segment and aim to improve the overall performance for domestic consumers.
According to the official release by Loongsoon, the company has launched three new processor lineups: the 2K3000, the 3B6000M, and the 3C6000. The first two models are based on the LA364E CPU architecture and feature up to 8 cores, with clock speeds of up to 2.5 GHz. The iGPU on these parts has also been upgraded from LG100 to LG200, offering 256 GFLOPs of FP32 compute, and an additional 8 TOPS of INT8 performance. The CPUs are designed for industrial applications, kiosks, and mobile terminals.
The biggest release today is the Loongson 3C6000 series, which features the company's 4th Gen CPU architecture with LA664 cores. The CPUs come in three variants: the "S" series with a single chiplet, the "D" series with two chiplets, and the "Q" series with four chiplets. Each chaplet has a total of 16 cores, so each lineup respectively offers 16, 32, and up to 64 cores. The CPUs feature a clock speed ranging between 2.0 GHz to 2.2 GHz. For chaplet interconnection, Loongson leverages its Dragonchain interconnect.
Additional details include 64 KB of L1i, 64 KB of L1d, 256 KB of L2 cache per core, and a shared 32 MB L3 cache. The Loongson 3C6000 "S" series features a quad-channel DDR4-3200 controller, and the other two lineups feature an 8-channel DDR4-3200 controller. Furthermore, the D/Q series can also be integrated into multi-socket solutions with up to 4 socket layouts. The "S" series offers up to 64 PCIe Gen4 lanes while the D/Q series offers 128 Gen4 lanes. The "S" series operates at 100-120 Watt TDPs while the D/Q series operates between 180-300W.
Loongson is also sharing some preliminary performance figures between its 3C6000 series and Intel's 3rd Gen Xeon "Ice Lake-SP" family. First up, the comparison is between the LS3C6000/S with 16 cores at 2.2 GHz versus the Intel Xeon Silver 4314 16-core chip at 2.4 GHz.
Loongson takes the lead in SPEC CPU 2017 (GCC15) with a higher integer performance while slightly falling behind in floating point tests. The differences narrow down with the 32-core option, while the 64-core variant at 2.1 GHz offers similar results versus the Xeon Platinum 8380 at 2.3 GHz.
The main selling point for Loongson's 3C6000 server CPUs will be their value and availability in China's domestic market. With the new chips out, we will see some new benchmark figures in the coming weeks.
