The new consoles certainly are an improvement in many ways, though I am a little sad that the CPU situation was so poor. I guess Intel was too expensive, as a dual-core Intel is faster CPU-wise than this 8-core netbook CPU (disregarding iGPU).
Intel + Discrete AMD/NV GPU would have been a lot better, but also a ton more expensive.
Just sticking with AMD though, something like a ~3Ghz 4 or 6 core Piledriver + Discrete 7870, along with a $10 ARM Quad-Core SOC (for multitasking in idle mode, low-power tasks, etc) and two pools of memory for system and GPU could have been more beefy (and undeniably more expensive).
It's telling that the Jaguar's single-threaded performance was beat by the PS3 CPU (and almost certainly the X360 CPU as well), and has to depend heavily upon multithreaded ability to get things done.
I can guarantee you this : low CPU performance will be something that is noted and complained about by devs for the entire gen, because no matter HOW good you code, low single-threaded performance is a serious pain in the ass if your project is ambitious enough. The X1 and to a greater extent the PS4's GPU sides are actually pretty good, but the CPU side of things is ... rough.
