it's got a 4 core ARM CPU and the GPU design they are using (same as the iPhone) has 4 "cores or at least that is what the designers call them. http://www.techradar.com/news/gaming/consoles/inside-the-sony-ngp-the-cpu-and-gpu-in-detail-924306

So is it like 25% faster than an iPhone 4 or is it magnitudes more powerful?

Single GPU in NGP is slightly faster than the one in iphone.

BUT NGP has 4 of them.

No not even close

 

For starters the both use completely different CPU/GPU architectures: The iPhone 4 uses a SGX535 with a Cortex A8 CPU, The NGP uses a Quad Cortex A9 and SGX543MP4

A single SGX543 is more than 4x more powerful than the SGX535. Its a quantum leap ahead of it, Hecks why go that far? the SGX540 (inside the Galaxy s) destroys the SGX535 in performance clocks per clocks

Its pretty much given the SGX543MP4 on the NGP would be clocked at the very least at 200Mhz, at 400Mhz more likely considering the Astonishing demos shown running on it which look on par with PS3 of course on a smaller res. 400MHz is not far fetched at all

A single SGX543 core would be anywhere from 4 to 8 times more powerful than SGX535

Let alone the actual quad core version used on the NGP, which is anywhere from 16x to 32x times more powerful than the SGX535

A Cortex A9 is a MAJOR improvement over the Cortex A8 in performance/efficiency it also featires more L2/L1 instruction caches which a help a huge dea. Add that advanatge by 4 and you you fot a huge gap between the two

Hardware wise the difference is huge, it is a magnitude more powerful/capable also the fact that it uses low level APIs it furthers that huge differenc eeven moe. Here's what Carmack had to say on Twitter about Sony's new gizmo: "Low level APIs will allow the Sony NGP to perform about a generation beyond smart phones with comparable specs.

So even know that the Specs are a manginude more powerful they havce the advantage of an low level API over smartphones, and even when the smartphones startc caching up on hadware 2 to 3 years from know NGP will still be a generation beyond on it games again thnaks to the low level API

actually imagination technologies  only claim a 40% increase in performance per core in shader heavy applications, and as those claims come from the manufacturer I wouldn't be surprised to see less than that in most cases. Thats not to mention how well the architecture actually scales with multiple cores, I have seen the manufacturer claim almost 1-1 but the NGP is the only device announced to use a quad core so far. How much and how fast the RAM the NGP has is the biggest ? over the NGPs performance ATM.

I have seen no evidence to suggest that the NGP has anything more than a 200mhz GPU TBH though it's possible they will go with a 400mhz chip I think that battery life and heat concerns make that unlikely.

You are correct about the APIs though. 

The real issue though is that the NGP at it's current size puts it more in competition with the iPad than the iPhone IMO...
