When I looked at the announcement of the new MacBook Pro Retina for 2015, I and many others were puzzled at the inclusion of the Radeon R9 M370X inside it. It doesn’t appear on AMD’s website at all and it doesn’t seem to fit in their current lineup either, with the R9 M360 being based on the Venus family (GCN 1.1), but shipping with DDR3 memory. Thanks to some RMP 2015 owners on Reddit, we now know that the GPU could be based on Cape Verde, which last appeared as the Radeon HD7770/R7 250X on the desktop. With GDDR5 memory on board, it outclasses the Kepler-based Geforce GT750M found in the 2014 model of the same notebook by some margin – in some cases, by as much as 80% in synthetic and gaming benchmarks. However, until reviews of the new MacBook Pro are released, there’s still the possibility that this is new silicon, and not three-years old hardware that Apple may have gotten a good deal on.
