New L3 SRAM???
Hey... I ordered a Ti 1ghz superdrive yesterday...
I am upgrading from a ti800 model... I want to know if this L3 memory is the same as the 800 model? As I recall, the L3 on the 800's was DDR SDRAM... the new ones say DDR SRAM....
What difference does this make??? I want to know what kinda performance change we will see???

According to powerlogix, there is practically no difference between DDR L3 SRAM and normal L3 SRAM, the important is it's size. So you wan't see any difference of performance, the DDR thing was just a marketing trick (and a loss of money).
not the DDR part... or at least I think thats what he means...
<strong>It was always DDR-SRAM. I'm not really sure why they ever claimed otherwise. The difference though is latency and cost.</strong><hr></blockquote>
Interestingly enough the german specification datasheet of the former G4 TiBooks (4/2002) correctly states DDR-SRAM, while the english version states DDR-SDRAM. Must be a typo-error.
If you are interested by the difference between DDR and SDR SRAM see this link : <a href="http://www.powerlogix.com/press/releases/2002/020826.html" target="_blank">http://www.powerlogix.com/press/releases/2002/020826.html</a>
The conclusion show that there is nearly no difference between the two types of memory : what is more important is the size of the L3 cache.
<strong>L3 cache is always static ram, wich means far better latency.

Then again, giving people the impression that DDR L3 brings absolutely no speed gain incidentally happens to be in PowerLogix' best interest, as they only offer SDR L3, so I wouldn't really expect this to be the most unbiased source around.

Perhaps but it's the only one.
