Not necessarily. They may just be (a lot) easier to spot.

They've already solved the memory bandwidth issue with the eDRAM in the Iris Pro Haswell parts.

It's a CPU core they're announcing, not an SoC.

And the PowerVR folks just bought their own CPU (MIPS).

So far, the PS Vita TV has only been announced for a Japanese release. If it were to be released with a DS4, it would have to be delayed for 3 months. Even then, the touchpad on the DS4 isn't a replacement for the touchscreen on the Vita for all games that make use of it, nor does it have an equivalent to the back touchpad or the cameras, so plenty of Vita games still wouldn't work on it.

It comes with a DS3 because it will be released before the PS4. Once the PS4 is out, a firmware update will be released to make it compatible with a DS4.

They don't have dedicated VRAM like a graphics card in a PC, they just allocate some portion of the main RAM as VRAM.

The license change happened more than a year before Sam Lantinga was hired by Valve.

As far as I know, the only difference between the PPE and a Xenon core is that the later has a modified VMX (AltiVec) unit. They upgraded the vector register count to 128 per thread compared to 32 per thread on the PPE and they replaced a few vector instructions with others that are more useful in gaming.

If you want more you should watch the video.

You'd think so, but, as the original Xbox has shown, that's not really the case.

The biggest difference between PC and consoles has always been that consoles have a fixed hardware configuration. That's still the case regardless of what CPU architecture they use.

The PS4 doesn't use OpenGL, so it's a moot point.

It uses an ARM SoC with a Vivante GPU.

ARM7TDMI is ARMv4.
