The first review of China's domestically produced Loongson 3A6000 CPU has been published, revealing better IPC than Intel's 10th Gen & AMD Zen 2 architectures.
A few weeks back, we reported that Loongson has begun shipping the very first PCs equipped with its latest 3A6000 CPUs in the Chinese domestic market. Featuring the new Dragon core architecture and a range of optimizations, the new chips are said to deliver a major improvement over the older 3A5000 CPUs.
In terms of specifications, the Loongson 3A6000 CPU features a quad-core design (4C/8T) and an operating frequency of 2.5 GHz (peak). The CPU uses a 4th Generation Dragon architecture which integrates LA664 cores with support for 128-bit vector processing extended instructions (LSX) and the 256-bit advanced vector processing extended instructions (LASX) along with SMT2.
The PC that the Loongson 3A6000 came equipped with is designed for the Chinese domestic market and includes the motherboard, a power supply, two 8 GB DDR4-3200 memory modules, a 256 GB SSD, and an AMD Radeon RX 580 graphics card. The CPU is seated beneath a standard circular heatsink with active fan cooling while the PCH rests beneath a smaller passive heatsink. Power is provided through an 8-pin CPU and 24-pin ATX connector. The CPU itself comes in the BGA form factor and hence is embedded into the motherboard.
The Loongson 3A6000 CPU was compared against the older 3A5000 chip along with the Intel Core i3-10100 and AMD Ryzen 3 3100 CPUs. In both SPEC CPU INT & FP tests, the 3A6000 performed up to twice as fast compared to its predecessor while offering comparable performance against Intel & AMD chips. The major difference was that the Intel and AMD chips run at higher clocks with the i3-10100 offering
