Where did I say it removes the CPU limitation entirely? You said that mobile GPUs are bottlenecked by mobile CPUs, so I pointed out that Apple is raising both at the same time so we will see double the performance of the A5 in regard to graphics.

Imo its completely pointless even trying to argue anything properly without even a single benchmark on a relevant OS.

We don't even know the clocks.
They've been pretty accurate in the past.

They said it's a dual-core Cortex A15.

A5X is a dual-core Cortex A9 at 1GHz, with the PowerVR SGX543MP4. The A6 is a dual-core Cortex A15 with what seems to be the PowerVR SGX543MP4 -- but no confirmation on the GPU yet but it seems likely as Apple has said it's twice as powerful as the A5's graphics.

The SGX543MP4's clocks in the Vita may be slower than in the iPhone though.
Qualcomm's Krait was first with ARM Cortex-A15 based SoC. They design their own chips using ARM IP though so it's not technically called a Cortex-A15.

The quad-core won't benefit any apps which aren't able to, by design, utilise more than one or two cores. The majority of apps will be like that, only intensive apps and games will really be able to support a quad-core. That's very simple to understand. Of course the other cores will be used to multi-task, but that still doesn't matter if you're never using up more than two whole cores in the first place.
No compelling reason to buy it over other offerings? It's got a better processor, better graphics, it's thinner and lighter... what's not better about that?

Yeah and what you've been saying is WRONG. Simple as that. Even if an App is only coded to use two threads the OVERALL DEVICE will be better off having 4 cores because of how the scheduler works as Domino said. the other cores... STILL get used. Just because an app is only coded to use two threads that doesn't mean the other cores are unused and wasted. It means the kernel can run other processes on the remaining cores. Quad cores are BETTER in today's devices!

What part of that makes sense to you? If an app has only two threads then the other two threads available will be used for other tasks and thus ALL threads are being used No matter whether the app is single threaded or multithreaded all threads of the device are being used and scheduled by the kernel's scheduler.

Sure enough if you're talking about purely apps then more fool you because the overall bigger picture is more important.

It can be as fast as it wants, it's still running the flop that is iOS6

So, the GPU is probably the same, but the CPU is upgraded for the A6 vs the A5X then? If I remember right, when the A5X was announced, its GPU was stated as being twice as powerful as the GPU in the A5.
