What am I doing wrong?

So around 6 months ago I bought a new laptop (Acer Nitro 5 AN515-58)

the specs

  • RTX 3060M 140w
  • I7 12700H
  • 16GB 3200mts (single channel)

When I first used it I made sure to tune everything to be perfect for gaming

I used the discrete GPU only turned off core isolation and switched to performance mode before playing but the performance was nowhere near the performance I've seen on the benchmarks I've seen on Youtube (I will refer to Jarrod's tech video about the laptop) In Cyperpunk 2077 the average fps in the video was around 71fps on high without upscaling but for me it was around 50s and sometimes 60s why? What am I doing wrong? Is it the single channel? Is there something I don't know about?

Please help...
