Data uploaded to the CompuBench database suggest AMD's mid-range Polaris 11 "67FF" SKU has 16 compute unit. If the Polaris GCN 4.0 architecture still has 64 stream processors per CU, this means this particular video card should feature 1024 unified cores.
You might wonder why it’s only 1024 SP, but let me remind you that new FinFET architectures have much higher transistor density per mm2. For example, Pascal GP100 has twice as many transistors as Maxwell GM200. Plus, AMD’s Polaris is using even smaller fabrication node than Pascal (14nm vs 16nm). In other words, those unified cores (CUDAs/Stream Processors) will be much more efficient than its predecessors.
