MacBook Pro 16,1 (2.4 GHz i9) is getting poor benchmark scores

Hi everyone, I have a MacBook Pro 16" 2019 with the i9 2.4GHz (i9-9980HK), 16GB RAM and the AMD Radeon Pro 5500M 8GB and I have tested it in multiple benchmarks and have noticed poor performance in some benchmarks in comparison to other peoples scores with the same hardware.

In Pugetbench for Premiere Pro, the first time I ran the benchmark I got a score of 413 (https://benchmarks.pugetsystems.com/benchmarks/view.php?id=121275), the second time - 304 (https://benchmarks.pugetsystems.com/benchmarks/view.php?id=121279), and the third time - 377 (https://benchmarks.pugetsystems.com/benchmarks/view.php?id=121290). I assume there was the difference between the scores because of thermals being higher after I had run it, and the third score being higher than the 2nd because there was a little while between running those two.

I found a result from a base model MacBook Pro 16" 2019 which has the 2.6GHz i7 and the Radeon Pro 5300M which achieved a score of 554 (https://benchmarks.pugetsystems.com/benchmarks/view.php?id=120117), and multiple of the 15" 2019s which shipped with the same i7 getting higher scores, even though the 15" should theoretically have worse thermal performance to the 16". I also found a few results from models with the 2.3GHz i9, which is supposed to be slower than this 2.4GHz model - some of those were also higher. While some were only a few points higher (20-50), some were over 100 points higher.

I have run the Geekbench 5 CPU and GPU Metal benchmarks, and while the CPU seemed to perform properly in Geekbench, the GPU was 26000 - 27000 points whilst the metal benchmarks page on the Geekbench 5 website says the gpu should be getting closer to upwards of 29000.

Does anyone have any idea why I might be experiencing this? Did I lose the silicone lottery or is this a problem and can it be resolved?

Thanks, Philip.

P.S. when was running the benchmarks, I made sure to have everything closed, nothing running in the background at all. The only time there was anything running in the background, it was things I couldn't close in activity monitor, or Macs Fan Control and that was only on the 2nd and 3rd try to attempt to better my scores by having both fans running at full speed the entire time instead of ramping up and down. This didn't work.
