Titolo: Intel Knew DDR2 was Poor Design

http://www.cooltechzone.com/index.php?option=content&task=view&id=1197
We all know how DDR2 is struggling to keep up with DDR, which in turn makes 
Intel struggle against AMD who has better performing microprocessors for the 
gaming and enthusiast crowd. Although Intel has managed to be "successful" 
with its latest generation of hardware in the OEM segment, thanks to Dell, 
majority of the enthusiasts tend to stay far away from Intel’s latest platform 
due to an unfortunate performance hit with newer standards and technologies.
After we recently published our AMD May Skip DDR2 Altogether report, a source 
pointed out a detail to us. According to the insider, Intel was aware of the 
poor design of DDR2, but continue to move forward due to its possible struggle 
to keep up with AMD. Since Intel never had a hard-hitting reply to AMD’s 
Athlon 64 microprocessors, Intel went ahead and introduced a new platform that 
would future-proof many systems with DDR2 and PCIe technologies. This could 
very well be a vision on Intel’s part, but thus far, DDR2 has not exactly 
matured in terms of performance and price parity, though it’s rapidly 
approaching that stage.
The source said Intel might follow on AMD’s footsteps if the world’s second 
largest chipmaker skipped DDR2 and went straight to either DDR3 or XDR. Intel 
has already started sampling both XDR and DDR3 for initial testing. The world’s 
largest chipmaker even has boards that support the aforementioned standards. 
Samsung is also ramping their production on XDR, so the chances of DDR2 having 
a short lifespan are highly possible.
According to the insider, Intel always planned DDR2 to quickly fade away from 
the market, so the company won’t be in a shock if they have to move to DDR3 or 
XDR in the near future. In fact, that was Intel’s plan all along, since DDR2 
was a poor architecture to begin with.
All in all, you can expect high latencies on DDR3 with huge bandwidth. Since 
DDR3 or XDR are talks of the future, our source was unable to comment on the 
new pricing models. Get ready, as the market is about to get complicated even 
more.
Povera Intel, oggi non gliene va bene una LOL !!!!

heh, vedi il performance in vita reale del DDR (ultimo risultato nelle
mie tabelle (colonna gialla) sul mio sito sotto comp/bench´ -updated
..
	col DDR3 la cosa potrebbe anche peggiorare! :-)))

Si ma le DDR3 dovrebbero compensare con la banda enorme.... Non c'è niente da 
fare, le XDR sarebbero proprio l'ideale....

Si ma le DDR3 dovrebbero compensare con la banda enorme.... 
se il memory controller non puo in vita reale sfruttare il bandwith
come tante volte succede, perche cambiare (noi non produttori) le
cose? Solo pomperanno i MHz di memoria per compensare il performance
piu bassa per clock (cose viste parecchie volte gia); simile e sucesso
passando da sdram a DDR ... ed da DDR a DDR2 ...
	solo per vendere roba "nuova" a noi ...

In realtà la DDR2 non sono male nella versione a 666 Mhz, la vera frequenza
standard di queste memorie. Per motivi commerciali si è spinto
inizialmemente sulle 533 Mhz, inferiori alle DDR 400 Mhz standard per via
delle latenze elevatissime, pari all'incirca alle DDR 266 Mhz. E' vero
ovviamente che in futuro si dovrà cambiare standard, come è logico data
l'evoluzione dei processi produttivi. Prima però si dovrebbe passare alle
DDR2 a 666 Mhz, già disponibili sul mercato.
