Nah, it's not a gpu, it's the drivers that are bottleneck, to be more specific it's a few features that dolphin needs to be implemented to the drivers. EXT_buffer_storage (that one became GLES feature recently) is one of them and base_vertex. That has been reported to ARM and they know there's a request so it's totally up to them. I'm planning to moan on their developer forums at some point and push them to implement this extentions in r6p0 ( which willbe released in about 12 months), don't think it'll help but I just feel like I need to do it 
The most exciting thing it's the Vulkan, so bad documentation is not yet available publicly. I feel jealous for the Kronos partners as they have it since the GDC or even earlier
