What high performance system do we need to rise the Symbol Frequency limit from 20MHz to a whopping 100MHz?

PC hardware or operating system?

With high-end desktop CPUs like a 12900K you can currently achieve a symbol rate of about 25-35 MHz before running into a CPU bottleneck (under optimal conditions). The relevant factor here is clock speed, not core count.

Higher values will result in CPU oversaturation, which will lead to dropped packets and may corrupt the signal. Changing the limit from 20 to 100 MHz is mainly about removing an artificial software limitation, and future hardware may be able to better utilize this.
