PART 1: Future Of Mobile Computing / Gaming
With the introduction of the iPhone 6s and rumored (but more than surely to be released) Samsung Galaxy S7; we are starting to get a glimpse of "Next-Gen" mobile computing. The Apple A9 SoC (System On Chip) and the Samsung Exynos M1 (or Exynos 8890) are both truly remarkable in terms of their performance.
To really intensify the "game" for Sony, Nvidia is also in the market of portable gaming. The Nvidia Shield Portable (the first of the Shield products) is a fully featured mobile gaming controller with an HD screen (1280x720 Resolution, NOT FHD = 1920x1080) and running Android 4.2.1 Jelly Bean stock (upgradable to Android 5.1 Lollipop). The Nvidia Shield Portable's Tegra 4 SoC, Though dated, is much faster than the Ps Vita Arm Cortex A9 SoC (which is also dated). Chipset manufacture: ARM, has released faster and more energy efficient SoC over the years than the Cortex A9.
The upcoming ARM Cortex A72 is said to rival the Intel Core M series (used the in the new MacBook and other ultraportable laptops). Nvidia recently released the Tegra X1. The Tegra K1 (successor to the Tegra 4, and the Tegra X1 predecessor) already matches last gen consoles according to Nvidia statistics. The Tegra X1 mobile SoC can deliver 1.0 TFlops of compute in 16-bit workloads (FP16) and around 500 GFlops for 32-bit workloads (FP32). This is quiet a feat considering that these mobile devices run on your average phone battery !

PART 2: Proper Optimization And It's Results
Many state that the Ps Vita is essentially a portable PlayStation 3. Benchmarks wise, it's pretty off. Both the Ps Vita ARM Cortex A9 (CPU) and and SGX 543MP4+ (GPU) are significantly slower than the PlayStation 3 CELL Processor (CPU) and RSX Synthesizer (GPU)
However, Benchmarks don't always translate into accurate real world performance. Though the Ps Vita hardware is significantly slower than the PlayStation 3 hardware, it does pull through when the games are properly optimized. When developers invest more time and money into making games for the Ps Vita, the games demonstrate what the Ps Vita is capable of. Killzone Mercenary and Uncharted Golden Abyss are excellent examples of hard work and dedication. However, games like Borderlands 2 and recently released Resident Evil: Revelations 2 are examples of degraded ports from it's console counterparts.

Though Uncharted Golden Abyss shows downgrades in its graphics department from it's PlayStation 3 counterpart, it still retains the overall excellent experience in terms of it's game play and functionality and is easily considered a "must have" in your Ps Vita library.

Similar case to Uncharted Golden Abyss. Graphics did take a hit, but overall gameplay and experience remains true in this mobile version. If your a fan of first person sci-fi shooters, it's another must have in the collection.
IMPROPER OPTIMIZATION = Borderlands 2 Ps Vita
Sorry No Comparison :(
Absolutely horrific. Refrain from buying this game at all costs. Texture are from the Playstation 2 days, frame rate is like a slideshow.
Follow the source to an extensive visual review.
Resident Evil: Revelation 2 Ps Vita
Sorry No Comparion :(
Mediocre port. Not much to say other than "It Works". Expect frame rates drops and significant visual downgrade.

Clearly the Ps Vita four year old hardware still manages to pull ahead of most mobile games. However, this is mostly due to the fact that the developers invest time and money into developing Ps Vita games and not because it has superior hardware.
