China-based Loongson Technology has unveiled the 3A6000 processor, more than a year following its initial announcement. The 3A6000 is manufactured using a 14/12nm process and is designed with four cores and eight threads. It operates at a base clock speed of 2 GHz and can reach up to 2.5 GHz with turbo boost, featuring a Thermal Design Power (TDP) of 50W.

 The processor has been deployed in an XC-LS3A6M motherboard by Asus and is currently being tested by Bilibili user Uncle Tony.  In terms of cache memory, the 3A6000 is equipped with a 256 KB L2 cache and a 16 MB L3 cache, mirroring its predecessor, the 3A5000. The processor also supports DDR4-3200 memory. When assessing its performance, particularly in the area of instructions per clock (IPC), the 3A6000 demonstrates capabilities comparable to Intel's Core i5-14600K under SPEC CPU 2006 benchmarks, provided the frequencies are aligned.

While the 3A6000 shows commendable IPC performance, contemporary processors from Intel and AMD often achieve clock speeds beyond 5 GHz, which translates into significantly greater overall processing capabilities.

Benchmarking under SPEC CPU 2006 reveals that the 3A6000 is competitive with Intel’s Core i3-10100, another processor with 4 cores and 8 threads. Yet, in UnixBench evaluations, the Intel processor surpasses the 3A6000 by up to 68 percent in performance. The gaming capabilities of the 3A6000 have not been conclusively determined yet.

An additional point of interest is the processor’s overclocking potential. Experimentation with liquid nitrogen cooling achieved a clock speed of 3 GHz, limited by motherboard capabilities. This indicates that the 3A6000 could potentially offer enhanced performance with advanced cooling technologies.
