PS3 has 256mb of RAM ????????????
definitely not
PS3 has 256mb of GDDR3 ram at 700 mhz and 256mb of XDR ram at 3.2ghz. In total ps3 has 512mb of ram . RSX has full access to the XDR ram (provided 32mb is kept for OS ).
ps3 has 512kb of L1 cache and 256kb of L2 cache per spe. In total ps3 has 2.3mb of CACHE memory
X360 has just 1mb of shared cache memory.Additional cache ensures frequent direct and indirect mapping
XDR works by a pointer to pointer technology and unlike x360 RSX has two buses one for GDDR3 at 128bit and one for XDR at 64bit.
64bit????
XDR works by a pointer to pointer technology and needs very small buswidth for execution. It transfers data in the form of multiple small packets rather than a whole chunk (as in case of GDDR3). XDR has very low latency and is way more efficient that GDDR3/GDDR4. a 16 bit bus is usually enough for XDR .
Because of the difference in latency and speed of the 2 rams devs sometimes cannot synchronize the rama allocation concurrently . Hopefully this will be fixed in the upcoming SDK revision
Diablo IV Lord of Hatred appears in Indonesia’s rating database for Nintendo Switch, raising questions about a possible new platform release.
Microsoft just shared new details about what's coming for Microsoft Flight Simulator 2024, and even a few tidbits about MSFS 2020.
Capcom tries something new and absolutely crushes it.
Why does anyone approve this garbage :/ We know the ps3 has 256mb of ram who cares already.
that this article is right approve it. Although you may disagree it does have 512 mb of ram
People are still going to come in and spout nonsense regardless of what's pointed out to them.
To socomnock:I thought everyone knew it had 512 ram its a fact how can anyone prove otherwise ive not seen anything about it having less even pc sites that have done spec checks on them know it has 512 god xbots r dumb why on earth are ur parents buying u xboxs when u clearly dont have the brain to switch one on
Nasim, you SUCK!
