Inconsistent Core Configuration Reporting on Arc A380

[MFdesigns]

Intel’s official specification [1] for the Arc A380 reports the following:

• Xe-Cores: 8
• Render Slices: 2
• XVE: 128

Which implies 16 XVE * 4 Xe-Cores * 2 Render Slices = Total 128 Xe-Cores * SIMD8 = 1024 “shader cores”. This means that there are 16 XVE per Xe-Cores which is consistent with oneAPIs GPU Optimization Guide “An Xe-core of the Xe-HPG GPU contains 16 vector and 16 matrix engines” [2]
But when using Level Zero to query the GPU configuration we get the following result:

• physicalEUSimdWidth = 8
• numEUsPerSubslice = 8
• numSubslicesPerSlice = 8
• numSlices = 2

Which reports that each Xe-Core (Subslice) has 8 XVE (EUs) and that each Render Slice has 8 Xe-Cores. Is it possible that there are two different ways of counting XVEs and Xe-Cores?

As an aside it seems that GPU-Z reports something completely different with 2048 shader cores which would result in 256 XVEs.
