Speaking of NAND, Xbox One supposedly has 8gb of NAND ram on top of the 8gb of DDR3.
Anyone know why even with this big honking extra amount of ram (I think it was meant for OS), the OS still runs like shit half the time?
Wait 8GB of NAND or 8Gb of NAND? I kinda got a pet peeve when people use gb or Gb for GB 'cuz the first two are for Gigabit while the latter's for Gigabyte
But I dunno what XBO's specs are RAM-wise outside of the DDR3 and ESRAM. But for why the UI can be kinda bad, well they've got a hypervisor (Hyper-V) with two separate partitions for games and apps.
So it's kinda like the OS has three layers :S
Is this the new 8GB of GDDR5 versus DDR3? I understand that power disparities at launch may very well be corrected or reversed in the subsequent revisions, but it seems odd that Microsoft would repeat the same mistake of the X1 vs PS4 at launch.
Nah, nowhere on the same level. Some people don't seem to understand how NAND actually works, or the fact that even 8 GB/s of speed and bandwidth for a nonvolatile memory is nothing compared to even the memory bandwidth for main "L4/L5" DDR3/GDDR5 memories of XBO and PS4, let alone the memory bandwidths for the GDDR6 XSX and PS5 will be using.
No matter what, NAND still operates as NAND, so it is limited by the inherent limitations of the technology. One system having an SSD speed of 6 GB/s vs. the other's 3 GB/s doesn't suddenly make up for the system with 3 GB/s having higher GPU compute, more RAM and/or more main memory bandwidth (as a hypothetical example). The purposes of those things and the SSD, even as a memory-mapped virtual cache, are very different and not directly comparable.
So anyone trying to sell this to you as the new DDR3/GDDR5 situation is grossly exaggerating and/or don't know how this stuff actually works xD.
EDIT: I'm NOT saying you wouldn't notice the difference with games that optimized for the extra throughput on the faster solution. However, some are thinking it's analogous to CDs vs. cartridges or something like that, or mechanical HDDs vs. SSDs. The differences in practice would be nowhere in that same ballpark, and there are other factors in system design which can impact the effectiveness of the SSD cache feature.
