GDDR is optimized for graphics performance, so the only engineering consideration is if that is more important in the tradeoff than latency. The Xbox360 used a similar GDDR3 unified RAM architecture which apparently did have some latency issues for the CPU, but wasn't really a handicap in context compared to the PS3, as the Rambus RAM the PS3 used for the CPU also had its own latency issue compared to regular DDR, although less pronounced.
System design is one of balance and compromise. Leaning towards graphics performance over CPU bottlenecks is a valid design decision as really, we're talking games consoles and not servers here. Nonetheless, it's not a done deal that GDDR5 is a silver-bullet for performance in the PS4.
