GDDR5 is not much faster than DDR3... (Xbox one) LINK FIXED - Page 2

This without the console contexts is the biggest laughing stock ever biggrin.gif
It isn't much of a difference because there is a CPU accessing the GDDR5 on the playstation and a GPU accessing the DDR3 in the Xbox.
Clearly GDDR5 in the ps4 is still vastly superior even though the CPU doesn't like it that much.

If I remember correctly, the Xbone runs three operating systems: a stripped down version of windows, xbox os, and a switcher os that runs the other two os's as VMs inside of it.

EDIT: With both Windows and Xbox OS running at the same time, they can be switched between very easily and fluidly. From a development standpoint it's much easier to setup as well, since they already had existing code for both OS's, why not just run them at the same time rather than try to make some weird hybrid of the two.

Also I may be wrong about all of this I don't have time to double check haha

They guy clearly does not no much about console hardware or GDDR5/DDR3 memory. Why he even bothered to create a video based on something he is so clueless about really is a bit silly.

And that lisp... my gosh, it's terribly annoying.

It makes sense. DDR3 is fast. The timings are low in comparison to GDDR5. The big difference is DDR3 has 64-bits per memory channel, and I'm assuming XB1 is dual-channel, giving it 128-bit memory. PS4, meanwhile, is using GDDR5 and presumably is running 256-bit memory (8 times 32 bits per channel), though 192-bit (6 channel) or 384-bit (12 channel) is entirely possible. GDDRx is better at handling graphics since it can cram so much in the data tubes, while DDRx is better with system memory because it doesn't typically need to copy HD textures and can be optimized for speed instead. I guess you can make an analogy using pipes? I'm bad at wording those, so I'll let somebody else do it.

The fact is that supposedly the XBO uses 3GB ram for the 3 systems it has loaded.

I'm not entirely sure on any details, but my best guess is that there's one main kernel (stripped down Windows 8, IIRC) running three programs, which function as virtual machines, at once, and can easily/quickly be Alt+Tabbed. As for why, you have three OSes optimized for various tasks. One for games, one for media, and another for something else. As much as I hate what MS has done, XB1 and Kinect are awesome from a technological standpoint.

EDIT: check two posts above me; that explains it better

GDDR5 is faster when it comes to video cards, DDR3 is slow on video card, but if MS can pull of this 3 OS thing it will make for a very smooth system indeed

Well Basically, this video was ridiculous, basically.

So basically the xbox360 is a glorified DVR/cable box.. And with 3 operating systems running no wonder it's running DDR3, imagine if it was running on GDDR5 the 3 OS thing would be almost impossible! Since the platform is already complicated they may as well run DDR3 and GDDR5 simaltaniasly to win the crown of the most complicated system in history!

Sony learned from the ps3 cell processor.. Complicated is not the way to go
