Sapphire Pulse RX 580 8gb Benchmark

I'm wondering what people are getting for benchmarks with the Radeon RX 580 graphics card. I've got the Sapphire Pulse Radeon rx 580 with 8gb and I've been rather disappoointed in performance. I've used the Geekbench 5 OpenCL and Metal tests and the gpu comes in rather low comparitvely. For the OpenCL test, I consistently get a score around 24k–26k. On the Metal test I get about 33k–35k. I got this card because it's natively supported and popular. I know mac takes a hit over windows ddrivers for GPUs but I score a 44k and above consistently on windows. That's almost a 50% performance decrease. What kind of results are other hackers getting? Is there a better benchmark test? Have users found ways to improve the performance of this graphics card? I'm running 10.15.5 on OC 0.5.9.
