thanks for the info, first time I have read this info

as for fkloster *inserthandgivingfinger*

lol this is freaking GREAT! I have, for years, been assailed by so many people on these forums spewing forth crap about rambus that didn't know the facts. Thank you Ice9 for you insight and for setting the record straight! Zippy where are you?

I had to make a choice Czar....:

1) Quit my job and comb the books to remove the 'burden of proof' from my heavily laden shoulders.... or

2) Get back to work, make money, and hope and pray that someone else 'spanks' all the non-believers @ anands!

RAMBUS DID THE WORK....NOW DDR WILL PAY ....poor poor JEDEC, what will they do now that DDR has been caught w/hand in the cookie jar?

Well, keep in mind that there's VERY few people who actually investigate the facts.

All i've really done is give this forum another whipping boy

looks pretty sweet to me! Lite on is much cheaper than the Plex....Plex is prolly going to last a bit longer

But then, if he gets the Lite-On for half the price of the Plextor, and the LiteOn breaks in a year or two, he can just get a newer model for the same price.
So, assuming the Plextor lasts twice as long and costs twice as much, you could always argue that the LiteOn gives a free upgrade halfway through it's life for the same price as the Plextor without an upgrade

Very true... Sunner

Thanks for the facts Ice9 a very interesting read. If I stopped buying products from companies that are perceived as being unethical then I'd have to throw my pc away. I believe that Microsoft's new licensing strategy is unethical but it won't stop me from using Win XP. Not until I learn Linux anyway. Anyway thanks for the facts, you'd make a good lawyer.

Whatever happened to fkloster?

He was the biggest RDRAM loyalist that I can think of on these forums. He came to these forums when RDRAM first came about and left just as RDRAM is leaving. Perhaps he moved to DDR and is afraid to return. I dunno. It's sad.

Does it really matter?

OK, I'm coming in late, so forgive me if I missed something.
After reading a good article on RDRAM (I think it was over the The Tech Report, but I can't find it now), I really felt that RAMBUS needs to really shape up or ship out. They had Intel backing and encouraging them for years, and they basically sat on their butts until Intel almost gave up on them, and then relased some great technology that they said would make everything else obselete. Well, anybody that knows Intel knows they don't release products without testing them to death, so their business practices did not gell at all. RAMBUS had a great thing, and they pretty much ruined it for themselves. Did you know that Intel didn't even have time to appove PC1066 RDRAM for the i850E? Yeah, so if you have an i850E with PC1066 RDRAM, you are on shaky ground, well, at least Intel thinks you are.

I don't think the general public ever like RAMBUS that much (it was overpriced for so long, and when it was released for the P3, it was total overkill in the bandwith department). So when Intel finally released DDR with the P4, it did really well, which I think caught Intel buy surprise. Intel was, in my opinion, very slow to adopt DDR. Look how long it took them to come out with Dual-Channel DDR which perfectly matches the bandwidth of the P4?! I remeber when the i845E was the hottest thing out, and was wondering why AMD had a dual channel DDR board out and Intel didn't. (and we all know how much AMD chips benefit from Dual-Channel DDR, note sarcasm.)

Anyway, Intel has finally given up on RDRAM, and so we are seeing better things come with DDR.

I personally don't see the benefit going with RDRAM. The boards that support it are pretty old, and don't have the latest features like Serial ATA, Gigabit LAN, 8x AGP, and support for hyperthreading (although you may be able to correct that last one with a BIOS update). Also, if you overclock, DDR will get you a good bit farther. Also, most i850 boards don't have the AGP/PCI lock that Intel DDR boards are so famous for. And you can get the new "C" chips with the 800 MHz FSB and DDR 400, which would surely be faster than a 3.06 with RDRAM.

RD Ram is dead and no longer supported by Intel, DDR2 will be the new equivilent to it speed wise, DDR is the currently used type of memory. Buying RD ram unless u REALLY need the small edge, is not viable because it will be gone soon, due to expense and lack of support.

No, hes still around. About time something beat 3 year old DC RDRam technology. Whats sad was how long it took DDR to beat RDRam in the first place.

DDR2. How ironic of you to say that. As I recalled, the GeForce FX5800 uses DDR2 @ 1Ghz, and Nvidia dumped it in favor of DDR for their GeForce FX5900.

RDRAM transfers 16 bits per clock cycle.

But you forgot to mention about the DUAL 16-bit RDRAM chanels being used by the 850E chipset.....

RDRAM is being hampered by the chipsets supporting it. If there is an RDRAM chipset that supports the faster 800mhz FSB P4 'C' processors ( and paired with an RDRAM memory frequency that matches it), I have no doubt that RDRAM would still be faster. It took a dual memory bus and a 200mhz (800 effective) FSB for DDR to surpass RDRAM (and not by a lot at that). Somebody made a good point here before that the P4 technology is a perfect match for RDRAM technology in that both are serial in nature. RDRAM is superior technology but what would kill it is the politics of the free-market.

Not sure if Anandtech has a 3.06 shootout between dual channel DDR vs. RDRAM, but TomsHardware does.

TomsHardware on Granite Bay vs. RDRAM 1066 using a 3.06HT:

Quake: RDRAM wins.
3dmark/Comanche/Unreal Tournament: RDRAM wins
MP3 Audio Encoding: RDRAM wins
Flask encoding: Single channel DDR wins (?!?)
Mpeg2 encoding: RDRAM wins
Sandra: cpu bench, multimedia, dual DDR wins
Sandra: Memory bench: surprise! RDRAM wins.
PCMark: RDRAM wins. By a pretty good margin.
Office/Internet: RDRAM wins, or TIES *OVERCLOCKED* DDR, Dual channel DDR trails significantly.
WinACE archiving: RDRAM spanks DDR.
Lightwave: RDRAM
Cinema 4d: Dual DDR
3dsMax: RDRAM
SpecViewperf: RDRAM

THG Conclusion: Considering the fact that Intel wants to position the E7205 chipset (Dual DDR266 SDRAM) as successor to the i850E (dual PC1066 RDRAM), the limited performance is disappointing, especially with regard to memory.

DDR's had so much time to catch up.... and it still hasn't. Maybe video cards should start using this stuff instead of the DDR they've *been* using

Not that it matters. Rambus already has far faster technologies available that blow even their own RDRAM out of the water. Time will tell if Intel ever plans on using them. If not, SIS 658/659 is on the burner for this summer.

That Toms article is using the GB boards at 2xPC2100, which we knew was a temporary solution from day one. Compare it to the 865 and 875--the real ones. RDRAM will still win in some cases, but...

rdram is definitely not as expensive as the anti-rambus people here like claim it is. The argument is about as valid as saying Intel is much more expensive than AMD, when in truth, the differentiation is around $15 per 256 mb. Heck samsung is selling 256 mb pc800 rdram for around $45 (but of course you have to buy two of them).

Right...I want some real memory. even 512MB is marginal now.
So 1GB.
2x512MB PC1066 RDRAM: cheapest on pricewatch is $216x2. So $432 for *the cheapest*
2x512MB PC3200 Kingston HyperX...good stuff: $109x2. $218 for some of the best.

I'm not saying it should be this way, but it is. Why RDRAM was damned, I don't know, but it was and is. I'm known to have trouble seeing things in the ways of stupid people. The companies should have given in to Rambus, agreed on ack royalties and future royalties, and gone on.
