If I remember the PSP's MIPS ran 1-333Mhz or something like that,where initially it was limited to 222Mhz by the SDK (to preserve battery) but later 333Mhz was allowed as well.
What are the raw performance specs of PSVita?

Not much of a redesign would be needed to allow going to 444MHz instead. A couple node shrinks would definitely get them there, and they'd surely want that anyway.

Sony won't up clocks only for new models. All PSP's can run at 333MHz.
I think 444 mode (if it is indeed the upper clock) in Vita is available without Wi-Fi working (some games disable it for extra performance).

Is there a chance that during web browsing the Vita allows a single core to clock towards 888MHz, for example?
I just find it very weird that Javascript is running unbelievably fast on a 444MHz Cortex A9.

CPU-wise 4x444MHz Cortex-A9 (3x that are really useful for games) is way behind all three of those. The only place where it really picks up at all is in integer SIMD vs Wii U and even in tasks where that makes a huge difference it's still probably not enough to overcome the massive clock delta.
I still find the CPU revelation shocking but with everything said it's even harder to believe that the people who found it got it wrong.
GPU-wise it's also quite a bit behind any of those three, although maybe not as far behind. It's hard to say exactly.
so vita is a slow, battery consuming, no game, game device 
btw im still on old firmware because i keep WAITING for proper "no fuzz" homebrew. But it never came. the closest one is Rejuevenate.
Luckily, Sony still allow their Activation Server to be reached so all my PS Plus game when expire, still can re-activate with WiFi, despite using very old FW

Outside of the "no game" part that's pretty much like 3DS, only that has significantly worse CPU and GPU power while not having significantly better battery life (at least if we're talking about the original one).
3DS hardware is totally sux. It even dont have proper standby low power mode so it drains battery very quick comared to vita in standby

It needs one. Drains battery in 2 days without game running. PSP could survive a month.Doesn't need one. Specs are already low enough.

For real? My wife DS lite lasts forever I'm a bit surprised

For comparison, Samsung released 2 SoCs in 2011 with an actual product (PSV released at Dec 2011 in Japan), Exynos 4210 and 4212. Both are dual core A9 with Mali 400MP4, CPU/GPU clock for 4210 is 1.2-1.4GHz/266MHz and 4212 is 1.5GHz/400MHz. RAM is 6.4GB/s. How is that compare to PSV SoC?

I believe performance wise, even with the lower clock, PSV was still one of the fastest mobile SoC that came out at that time frame. They probably could came out with a faster SoC, but the power consumption wouldn't be pretty. Probably the decision to go with 4 cores was more about saving power, thus 4 lower clocked cores.
