Nvidia's vendorID: 0x10DE to 4318?

According to Nvidia’s website http://www.nvidia.com/object/device_ids.html, NVIDIA’s vendor ID is 0x10DE. However, when I use Vulkan command vkGetPhysicalDeviceProperties, it reports vendorID:4318.

I also saw from other answers such as https://devtalk.nvidia.com/default/topic/543715/cuda-programming-and-performance/cl_device_vendor_id-cu_device_attribute_pci_device_id-/post/3806877/#3806877 that Nvidia’s vendor ID is 4318.

Question: How do I relate/convert 0x10DE to 4318?

0x10DE is the hexadecimal notation of the decimal number 4318. They are the same value, just expressed differently.
