I was reading the article from Eurogamer on the PS4 games and I have to say that there probably will not be a big difference between the PS4 and the X1.  If you compare the games that were running on PS4 hardware and games running on X1, it would be hard to state any realy performance advantage from the PS4.  In fact a lot of their games suffered issues and dropped frames to 20FPS   I believe in the long run, the seperation between the 2 consoles will always be the developers working on the projects then any actual hardware advantage.

While I will confirm Sony has the better GPU, they messed up again.  GDDR5 RAM is great for graphics, it should make nice pretty pictures – But unfortunately, it comes at a cost - huge latency.

I'm not talking about twice as bad, or even 5 times, but 7-10 times as much latency as DDR3 memory.  It will cripple all the other advantages they put in it – like the wider bus width, speed, etc.  It’s really a shame.  It will effect everything thing that isn’t just a picture (AI, Game play, etc.)

It reminds me of a business person making a decision that doesn’t understand the consequences.  Like the people that messed up the cell, or the person that stopped the first Kinect from having it’s own processor.

The best estimates I have seen is that, because of these blunders, for most games the PS4 will run just a little bit behind the Xbox One.  Hence, what you are finding with the lower rate.

Did they now? The latency is nowhere near where your suggesting at all. Maybe about 20-25% max. You also forget the advantages of the unified GDDR5? Both CPU and GPU can access it at the same time. Once the developers get their heads round this was the machine fly. No need to send information back and forth between memories.Everything the GPU needs from the CPU, it can access. Everything the CPU needs from the GPU, it also can access. There is NO need for it to copy data from the main ram to a different pool of RAM. That along with the huge bandwidth advantage, will put it ahead of the X1.

latency will still play a big role in the CPU getting the information it needs fast enough for it to perform its calculations.  The CPU works on smaller sets of data so it crunches those pretty fast but if its dealing with latency issues with the ram, it will have an effect.  No matter how fast one part is, the complete system will always be hampered by its slowest component.
