China's domestically developed Loongson 3A6000 CPU has shown promise, but it still needs to catch up to the latest offerings from AMD and Intel in terms of real-world performance. According to benchmarks conducted by Chinese tech reviewer Geekerwan, the 3A6000 has instructions per clock (IPC) that are on par with AMD's Zen 4 architecture and Intel's Raptor Lake. Geekerwan used the SPEC CPU 2017 processor benchmark to compare the raw benchmark results of all the CPUs, which were clocked at 2.5 GHz, with Zen 4 and Intel's Raptor Lake processors. The Loongson 3A6000 appears to match the latest designs by AMD and Intel in terms of integer results, with an integer IPC measurement of 4.8, while Zen 4 and Raptor Cove have 5.0 and 4.9, respectively. However, the floating point performance still lags behind significantly. This demonstrates that Loongson's CPU design has the potential to catch up to global leaders, but further development is needed, especially in terms of floating point arithmetic.

However, the 3A6000 is hindered by low clock speeds and limited core counts. With a maximum boost speed of only 2.5 GHz across four CPU cores, the 3A6000 cannot compete with flagship chips like AMD's 16-core Ryzen 9 7950X, which runs at 5.7 GHz. While the 3A6000's IPC is impressive, its raw computing power is only a fraction of that of leading x86 CPUs. Loongson must improve its manufacturing process technology to increase clock speeds, core counts, and cache size. The strengths of the 3A6000 highlight Loongson's ambitions: an in-house LoongArch ISA design fabricated on 12 nm achieves competitive IPC compared to state-of-the-art x86 chips built on more advanced TSMC 5 nm and Intel 7 nm nodes. This demonstrates the potential behind Loongson's engineering. Reports suggest that the next-generation Loongson 3A7000 CPUs will use SMIC 7 nm, allowing for higher clocks and more cores to better utilize the architecture's potential. Therefore, we expect the next generation to set a new standard for China's domestically developed CPU performance.
