Or the CPU is just so slow comparatively...
What's indicative is i5 750 and phenom x4 955. At those clocks they have similar single threaded performance, the main difference is i5 has integrated pcie controller and better memory controller. Radeon loses 10 frames there.
Maybe devs have some leftover code from console's heterogeneous memory optimizations for GCN code path :laugh: that would be ironic ... we have x86 everywhere and instead of maintaining only x86+GCN and x86+CUDA codepaths, you still have to maintain all codepaths even xb1 separately to benefit from that weird extra on-chip cache.
