It seems you're referring to older hardware with just two processing units. Those were common in the past, but today's CPUs typically have multiple cores for better performance. More cores generally mean more threads and improved efficiency.
I believe @Sree357 is talking about CPUs like IBM's Power9, which supports either 4 or 8 way SMT. POWER9 - Wikipedia This technology is mainly beneficial for specific tasks. With only 2 way SMT on consumer chips, the gains are limited to about 20% per core at best, and in some cases it can even hurt performance. Additionally, increasing the number of SMT threads brings diminishing returns, making it not worthwhile for consumer processors to go beyond the standard 2-way configuration.
CPU designs typically feature one or two threads per core, which explains why some processors offer 8 cores with 16 threads or 4 threads per core resulting in an 8-core/32-thread configuration. However, not all CPUs provide extra threads, making it less beneficial to go beyond 16 threads. In consumer applications, specialized tasks are needed to fully utilize more threads, which isn't commonly available. Therefore, opting for a higher thread count like 16 per core is generally more advantageous.
