Nvidia bitterness continues, compares PS4 specs to a 'low-end CPU'

Does Nvidia have anything similar to the APUs ?  

 

Yes.
nVidia Tegra, however it's targeted at the ultra low-power market. Aka. Tablets and Phones.
However, it's not far-fetched to say they couldn't engineer say... A Geforce 660/670 with a 16 Core (Or more) ARM processor all in one package to drop into a console.
Just unfortunatly the CPU performance of ARM chips leaves much to be desired as they have an even lower IPC per core than Intels Atom, which AMD's Jaguar leaves both in the dust due to it's OOO design.

Isn't Tegra a line of GPUs for mobile devices ? 

 

 

It's a CPU and GPU and chipsets aswell as other logic all on the same die. Aka. SoC or "System on a Chip".
AMD's APU's are essentially the same without the chipset and other logic and uses a CISC x86 for the processor.

There's also another important point: x86 has had also 64bit versions for almost 10 years now, since the first Athlon 64, while ARM 64bit versions are very recent and not widespread, and you need more than 32bit to address more than 4GB RAM directly without inefficient workarounds. As smartphones and tablets still use mostly 32bit versions, a 64bit ARM-NVidia APU couldn't enjoy the same economies of scale of an x86 one. Also, as you wrote, ARM up until now has had very low power consumption, but low computing power versions for tens years, and hasn't been scaled up again to desktop or notebook PC or home console computing power levels yet, last time ARM had versions comparable or more powerful than competing x86 CPUs was in its first years, when it was used in the first RISC personal computer, the Archimedes (back then it ate Motorola 68k CPUs for breakfast, not to mention the slower x86 ones).
