WWDC20 Ray Tracing support for Intel Xeon W

It seems that the WWDC20 Ray Tracing examples need a Intel Skylake GPU or above, the Skylake was included in MacBooks released in Early 2016. But the Ray Tracing examples do not seem to work with the Intel Xeon W in the iMac Pro and also the new Mac Pro 2019? The Mac Pro is Apple's most powerful machine, surely the Intel Xeon W should have enough power to run the Ray Tracing examples?

When I try to run the sample below I get the error "Ray tracing isn't supported on this device".
