| JEMC said: From Anandtech's analysis, page 3, third paragraph (link found on the OP): A look at Wired’s excellent high-res teardown photo of the motherboard reveals Micron DDR3-2133 DRAM on board (16 x 16-bit DDR3 devices to be exact). A little math gives us 68.3GB/s of bandwidth to system memory. The kind of RAM and its speed are known things, but it's true that how many of this RAM is reserved for the OS(es) is still unknown. |
Plus, like this generation anyway, as the years roll pass Sony, Microsoft and Nintendo will make some tweaks and optimisations and reduce the amount of ram the Operating Systems use anyway, so initially it's a rather non-issue untill later on in the consoles life anyway.
Also, that memory bandwidth was rounded up. It's actually 68.256Gb/s rather than 68.3. :P
The math is: DDR clock rate * Bits transferred per clock / 8
I.E. 2133 * 256 / 8.
