In an interesting article from PCPer today, recent tests and benchmarks for Intel's new Kaby Lake-G processors with Radeon Vega M Graphics show that the GPU may be more Polaris based than Vega. The first hint was that in AIDA64 the GPU in Kaby Lake-G is listed as "Polaris 22", while that could just be coincidence, the more salient point is in DXDIag the GPU does not support DirectX 12.1, and further testing in SiSoft Sandra shows similar FP32 performance between Kaby Lake-G and Polaris, hinting that the GPU in Kaby Lake-G does not support "rapid packed math" Interesting stuff for sure. I honestly don't think that the GPU in the Kaby Lake-G is specifically Polaris based, but perhaps a yet unnamed Vega, perhaps the first implementation we are seeing of the upcoming 600 line of GPUs. While it may not have rapid packed math, the quote below outlines the reason for my assumption. What Kaby Lake-G does have that leans toward Vega is support for HBM2 memory (which none of the Polaris cards have) and "high bandwidth memory cache controller and enhanced compute units with additional ROPs" according to the statement from Intel given to Tom's Hardware.
