all this next gen talk...got me hot and excited about new consoles dev....then i realized we just had a new console launched..PSVita! Yet little do we know about the hardware inside it...no? What are the raw gpixel and gb/s can it run itself at..? We dont even know how fast the gpu nor the cpu nor the memory is clocked at...? Is this Sony's way of Apple-ing their hardware in mystery talk...or just that mobile chip providers are just that anal about disclosing their SoC specs?
What are the raw performance specs of PSVita?

I don't think this information has been released to the public. Sony seem to be more tight lipped about Vita than PSP.
The raw GPU stats are the same as the iPad 3, only on a smaller screen and with a few changes to the spec. The CPU is probably in the realm of the Tegra 3 in performance. What's not apparent are the clocks, though with the battery life being quite poor compared to a phone or tablet you have to wonder where it is all going.
Don't forget that the Vita has 128MB VRAM, that is probably faster, though I don't know if we know what the bus layout is
I don't fully understand your comment about the battery life. Have you tried any intense 3D gaming on a phone or tablet yet? That's pretty harsh on the battery too. My phone lasts 30 minutes if that. And tablets have a massive battery compared to the Vita.
Are they really? My guess is the GPU is probably severely underclocked: most titles struggle to maintain even 30fps at the PSV resolution, also, I can't think of a game that can compare to infinity blade 2; and that game is running near 60 fps at more than 6 times the resolution of the PSV screen.
So yeah, I don't believe a word of the "PSV had the same GPU but with dedicated RAM!"-claims, with regards to performance. Maybe the same GPU, at 66 or 100Mhz
6x the resolution? PSV is 960x544. 4x the resolution is 1080p. If you think Infinity Blade II is rendering at iPad 3's native resolution, you are sorely mistaken.

I think I read somewhere that Infinity Blade 2 runs @ 1600*1200 on the ipad3 (so ~2.5x the original ipad).
It's still a gigantic resolution for that form-factor though and there should be minimal aliasing, if any.
Not that I'd want a game like Infinity Blade in the Vita.. I expect something more substantial than a "hack&slash on rails" from a dedicated gaming console, otherwise I'll just play it in my smartphone.
I'd be all over the PS Vita if they had a smaller, "PSP-Go like" version with SD Card slot (and if it eventually gets cracked and turned into a fulll-fledged Android tablet, that's perfect).
I've grown fond of Sony's handhelds as of late.
They're one of the few companies that are trying to be successful by doing their own thing and not just copying apple, they're honoring their promises regarding ROM updates and they've been releasing some quite nice products.

The screenshot I could find was certainly upscaled along those lines. IB2 itself doesn't look amazing to me based on the gameplay clip I found. There are no shadows and it's a simple on-rails trek through the environment, so it can be carefully managed. I don't think there's any legitimate comparison of relative performance going by that and Vita games. that said, 60 fps on a UE3 engine is better than I expect based off UE3 on PS360. Looks like Epic have really optimised the engine to corner the professional middleware for iPad early on.
The only thing really missing from Vita specs are the clocks. It's basically the same internals as iPad 3 with added VRAM, which should be offering considerable improvement. Maybe someone with better knowledge of both libraries can find a UE3 comparable game on both for comparison?
Sorry, I didn't know about Infinity Blade's internal 1600*1200.
I thought 6 times because 960 fits 2 times in 2048 and 540 fits 3 times in 15xx so.
But still, 3 times the resolution is still a feat, even without shadows.
My guess is that the GPU is at half the ipad3 speed, and that the Vita OS takes up the rest.

I think the GPU in iPad3 is at 250, and 200 in Vita. The Bus is more interesting and less known. On my iPad3 IB2 isn't a consistent 60fps at all though. Camera pans are extremely slow, even when you have somewhat of control over them when you are standing in a specific location. One enemy at a time, nothing dynamic, etc. There is some shadowing, and there are god-rays ... It is definitely a nice showcase of graphics engine features in EU3 on iOS, but comparisons to anything on Vita are a bit of a stretch for determining performance.
IB2 certainly isn't a shining example of a deep and complicated game. Static backgrounds, very limited viewing area, no shadows. Some nice hi-res textures and very shallow game play. Even Resistance on the Vita, whilst being a little bland at the beginning, is more impressive. Besides my iPad3 struggles far more than my iPad2 because of the increased resolution.

I was just a little surprised at how short the battery life is on the Vita. My Transformer Pad 300 seems to quite easily pull 4 hours + playing ShadowGun THD (that's a nice looking game - better than NOVA 3).

Shadowgun looks better than NOVA3?
Unless there's a huge difference between the Tegra 2 and Tegra 3 versions, I'd find that very hard to believe..

I think the GPU is 200Mhz like iPhones because of smaller batter compared to iPad GPU
clock of 250Mhz. If they bump it to 250Mhz with the 28nm version we could see more Native games
Too bad nobody is putting UE3 to good use on Vita http://www.youtube.com/watch?v=WyNSJHafxrA

Don't forget ipad 3 has quad channel memory..
I doubt the 4 cores will be clocked above 1gHz, and I also doubt they will as heavily optimized like exynos or even krait running on separate voltage rails..
Ipad3 also only has 2 cores...so I'm guessing vita is a more balanced system with a lower resolution screen to dial up the effects.

Shadowgun THD looks substantially better than NOVA3, better water, lighting, particles, and even cloth simulation (check out the flags)
I was quite pumped for NOVA3 but visually it is a bit of a let down.

What's the difference between thd version?
The THD version supports Tegra 3, so you get a whole raft of extra effects. There is a new Zombie killer game coming out and there is a comparison video between what they call standard Android and THD. There's quite a difference.
