My 2020 iMac with Radeon Pro 5700 XT scored unusually low in the Geekbench Metal benchmark. One of the workloads failed and was assigned a score of 0, but the OpenCL benchmark completed normally with a normal score.
I suspect this may be a compatibility issue between macOS Tahoe, Geekbench 6 Metal benchmark, and the AMD Radeon Pro 5700 XT, because OpenCL completes normally and Apple Diagnostics reports ADP000.
An Apple Diagnostics score of ADP000 means no hardware faults were found. A failing Geekbench 6 Metal workload resulting in a 0 score alongside a normal OpenCL run points to a software-level Metal compiler or driver micro-glitch rather than broken silicon.
Try this
Safe Boot Test: Boot your iMac into Safe Mode to clear dynamic system caches and force standard native graphics drivers, then test Metal performance again.
Reset NVRAM / SMC: Shut down your machine completely, wait 10 seconds, and turn it back on. For an Intel 2020 iMac, resetting the SMC and NVRAM helps clear low-level persistent display and PCIe configuration registers.
Reinstall or Update Geekbench: Ensure you are running the absolute latest minor version of Geekbench 6, as early point releases occasionally mishandled specific AMD Navi instruction sets on newer macOS builds.
