Uh huh... I'm still waiting for the explanation as to why the 720 will be more powerful.
Because the devkit is more powerful.
The power 7 is ABSOLUTELY fantastic. It is.
But its been reduced from 8 to 4 cores, and underclocked a GHz to around 3GHz. (power 7 performance is linearly scalable by clock speed, so we are looking at something 3/4 the power of a 4Ghz power 7.) Also very good.
Durango devkits have been confirmed to have a full 8core cpu. They are simply shooting higher. Another 4 cores to make up for isn't something to scoff at.
Wiiu has devkits with 2.5-3 GB ram.
That means wii u will have around 1-2GB RAM in retail. That is fantastic.
Durango has been confirmed to have 6-8 GB ram for its dev system. Which leaves us around 4-6 GB at retail.
The gpu seems fairly comparable.
They are just aiming a little higher.
Though it is worth noting ms plans to put a version of windows 8 on the box, and I wouldn't be surprised to see a core devoted to kinect, and a core dedicated to windows 8 & multitasking, and about 2GB reserved for the os and multitasking media.
They are just aiming at a performance area a little higher.
Of course, thats not saying they ate going to REACH it. No system EVEER reaches its peak performance.
I am reasonably certain the cube is the closest.
Systems constantly bleed performance, keeping them from reaching the 'paper specs'.
Is the processor vin order? yes? real world performance loss.
Is the processor cache enough to generally stave off resorting to main memory? Every time its not, real world performance loss.
How is the branch prediction? How bad is the penalty for a miss? HUGE realworld performance loss possibilities.
I know enough for what the general area they are shooting for seems to be with yhe info available... And its a little higher than the wii u.
I DONT have enough information to know how close the real world sustainable performance is going to be to what they are shooting for.
I do know, that the difference is going to be negligable this time. Its not going to be remotely close to a wii situation.
