8GB of GDDR5 running at 176GB/s

Of that the speculation is that 1 CPU core (in conjunction in a seperate ARM CPU reserved only for the OS) and between 512MB to 1GB of RAM is OS reserved, with the rest available for games.

So the GPU is a 50% upgrade. The PS4 offers between 2-2.5GB more RAM. That RAM also runs significantly faster than the XB1's and with no need to manage data flow through the ESRAM.

The core silicon alone for these two devices are VERY different. Early rumors that were tied to these same numbers months ago make a Radeon 7700 to Radeon 7800 series. That now seems to be a bit generous to the Xbox One, but not entirely inaccurate. The PS4 has the biggest hardware gap we've seen since the original Xbox was released nearly two years after the Playstation 2. Their similarity as x86 CPUs with AMD designed GPUs only makes this gap more important because fine tuning to the more powerful hardware is substantially easier for developers.
Great Scott!
