Loongson 3B6000: Lower Than Expected Performance

A test conducted by Phoronix highlighted the performance of the Loongson 3B6000 CPU, a 12-core processor manufactured in China. The results indicate that, on average, this CPU is approximately three times slower than AMD's latest Ryzen 5 9600X, which has only 6 cores.

Limited Clock Speeds

The main cause of this performance disparity appears to be the low clock speeds of the Loongson CPU during Linux tests. This data highlights how the number of cores is not the only determining factor for a processor's performance, and how optimization and architecture play a crucial role.

General Considerations on CPUs

The performance of a CPU depends on a combination of factors, including the number of cores, clock speed, internal architecture, and the amount of cache. Software and the operating system can also significantly influence benchmark results.
