As other posters have mentioned, this has 2 Cortex-M33 cores @ 150 MHz, not @ 300 MHz.
Cortex-M7 is in a different size class than Cortex-M33, it has a speed about 50% greater at the same clock frequency and it is also available at higher clock frequencies.
Cortex-M33 is the replacement for the older Cortex-M4 (while Cortex-M23 is the replacement for Cortex-M0+ and Cortex-M85 is the modern replacement for Cortex-M7).
While for a long time the Cortex-M MCUs had been available in 3 main sizes, Cortex-M0+, Cortex-M4 and Cortex-M7, for their modern replacements there is an additional size, Cortex-M55, which is intermediate between Cortex-M33 and Cortex-M85.
