Good point on the bandwidth issue, I forgot how optimized the PS2 was for fast data transfer, allowing it to be compeitive with not much ram at all.
But it\'s important to note the BR-ROMs will be running faster than 1x. On the official Blu-Ray site they are saying there will be a faster v2.0 spec, and in the future it\'s expected to be 8x or more. Just for the hell of it:
36Mbps (8x) = 36 MBps.
256MB / 36 MBps = 7.11 seconds
Sorry THX, forgot this thread...
hum, the 1x speed of Blu-Ray is 36M
bps ( ==
not Bytes per second). 36Mbps == 4.5MBps (I did the math in my post above), so it would take ~57 seconds for the complete 256MB of RAM to be filled up. Sorry.
You are right though that 2x speed is the minimum we could expect for PS3. Hopefully even 4x. Time needed to fill 256MB of memory would be in that case ~28 seconds (2x) or ~14 seconds (4x).
One other thing to factor in though, is that those are the maximum speeds (36Mbps for 1x) and only possible on the outer layers of the disc (it runs the fastest), meaning that speed will vary and achieve only the maximum when it hits the outer layers. In other words, loading times should be slower again a few seconds.
The situation gets even more depressing when you think of the possibility that PS3 may have more than 256MB of RAM. That\'s quite unlikely though IMO. On the other hand, Xenon (Xbox2) is expected to have at the very least 256MB of RAM. Rumours is 512 or even more. Wonder how they\'ll solve this problem...?
Paul2:
hmmm....just because if a console have 256 MB of main ram doesn\'t mean it have to use up all 256...
Hum, yeah - not necessarely. My point though was trying to illustrate the difference between PS2 reading speeds and PS3\'s. The problems their facing is the same - and at that, PS2 was fairly quick and even then, we have games taking up to half a minute for loading.
