Not bad I can imagine that they can keep up with the Ice Lake, and the Vega units should also be slower
The VEGA GPU should be 30% faster than the strongest Ice Lake unit:
The old iris units were sometimes faster than the current Vega, don't think they are faster
The AMD cpu's plus GPU shave off the Intel derivatives, the shaders are less but still faster than the predecessor and when were the iris faster? So far I've only seen the opposite
