180-Day Domestic AI Server Production Breakthrough

🔑 Enhanced Key Takeaways

• •Loongson 3C6000 is available in S (16-core single-chiplet), D (32-core dual-chiplet), and Q/3E6000 (64-core quad-chiplet) variants using LoongLink interconnect technology for scalability.[1][3][4]
• •The processor delivers SPEC CPU 2017 integer performance 35% above Intel Xeon Platinum 8380 in 64-core configuration, though trailing by 14% in floating-point tests.[3]
• •Loongson 3C6000 features per-core caches of 64KB L1i, 64KB L1d, 256KB L2, plus 32MB L3 per chiplet, with TDP ranging 100-300W depending on model.[1][4]

🛠️ Technical Deep Dive

• •Loongson 3C6000 uses 12nm process with LA664 cores at 2.2GHz, 16 cores per single die, supporting simultaneous multithreading with 4 integer, 4 vector, and 4 memory units per core.[1]
• •MESH on-chip interconnect with 32MB shared L3 cache per die; quad-chiplet 3E6000 links via LoongLink (akin to NVLink/Infinity Fabric) for 64 cores/128 threads.[1][3]
• •Memory: 4-channel DDR4-3200 (72-bit ECC) on single-die, scaling to 8-channel on multi-die; PCIe 4.0 x64 (single) to x128 (multi); SM3/4 crypto >16-30Gbps.[1][2]
• •TDP: 100-120W (16-core S), 180-300W (32/64-core D/Q); supports 4-socket multi-socket configs on D/Q series.[4]
