It looks like NVIDIA is planning on pushing the value/performance ratio envelope even further with the next generation of their Shield portable gaming product. The Shield 2 will reportedly contain a 2.5GHz quad-core Tegra K1 SoC, and will include an insane 4GB of RAM!
Here's a quote with more of the details,
The device has a purported resolution of 1440x810, which probably means 1440x900 (WXGAII) sans the 90px allotted to the Android software navigation buttons. The resolution amounts to a 16:10 wide-screen display of unknown size. We reckon NVIDIA won't go past 6 inches if it wants to keep a sensible handheld profile, but who knows.
Previously, we've seen the K1 SoC obtain a godlike 43,851 result in the AnTuTu benchmark, blowing the Snapdragon 801 CPU out of the water and probably capable enough to beat the Snapdragon 805 when Qualcomm unleashes it. Alas, making such a powerful CPU manageable in terms of energy consumption and heat dissipation is a task that NVIDIA is yet to prove it can handle outside of its test facilities.
It's amazing how fast mobile devices are evolving. It seems like it won't be too long before they catch up with consoles like the Xbox One and PS4.
