Does anyone seriously use a product featuring rambus designed components?

Wheres the damn EU when you need it, oh wait there too busy picking on companies that actually make something useful.

Exactly, when was the last time they actually "made" something other than nuisance lawsuits that hold technology back?
The last thing I recall is the ill fated PC800 chips that cost an arm and a leg, overheated and you had to use those stupid crimms to terminate the empty channels. Ooh, then there was the XDR super fast ram that never saw the light of day.

You guys realize that the PS3 uses XDR memory, right? You also remember the performance of RDRAM was excellent on the Pentium 4, right? And the price had dropped to parity with DDR by the time it finally stopped being used?

The failings of RDRAM on the PC platform have little, to nothing, to do with the memory itself. People think badly of it because of Intel's handling of it. The i820 was the first chipset for it, and paired single channel RAMBUS with a processor that could not use it (the Pentium III), but suffered all the disadvantages of the higher latency. It was followed by the i840, which was an excellent chipset for a processor that could barely use the now doubled bandwidth of this dual-channel chipset. The i840 lowered latency appreciably though, through interleaving, so showed very strong performance even for a processor that was bandwidth limited. It was also very useful for dual-processing configurations, because the "bursts" from the memory to memory controller were over relatively quickly (since the bandwidth was effective to it, but slow to the processor itself), thus leaving it free to possible service the other processor. The i850 followed it, which has EXCELLENT performance for a processor (Pentium 4) that could actually use it, and easily outperformed DDR platforms released by VIA, SIS, and later even Intel.

So, RDRAM actually was matched to a processor that could not easily use the bandwidth, although it was not totally useless (dual processors could use it a little, and of course AGP shared bandwidth with the processor, so there were a few situations and benchmarks that were helped), it was not far from it. Recall also that DDR on the Pentium III showed essentially no advantages as well, except in the same type of benchmarks, over SDRAM, but clearly was not a bad technology either. The Pentium III was just poorly suite to both. Intel did this, of course, to create an industry for the technology so when the Pentium 4 came out, there would be enough memory. Ironically, it worked in one sense, but by the time Intel had a product that could use the memory to advantage, and had achieved price parity, people hated Rambus so much, and it suffered such a bad reputation, that it was eliminated anyway, despite being ideally suited for the Pentium 4.

Not that this has anything to do with RDRAM, anyway. Rambus claims they they own technologies that are used in mainstream memories, and some courts just happen to agree with them.

yes, the whole issue with rambus has always been their business tact and not their products. their products are actually quite good, they just tend to charge more than most people are willing to pay. since the trend has been to get the most performance from the cheapest available parts, technologies that are far more advanced aren't really being put out since their licenses cost more than consumers would pay for them. so they languish and we get incremental updates to the same old tech. it does the job and sometimes they even put out updates that have reasonable leaps but it seems long gone are the days when the difference between the cheapest and the most expensive parts in a given category actually gave you a performance difference you could notice without having to run benchmarks.

I thought RAMBUS was a law firm since 2000?

I thought RAMBUS was a law firm after year 2000?

sorry for all the double post.. kept saying i can't login and refreshing the page.

Its not your fault they won't let us delete posts, or edit comments in these threads, Cat.

On the patent issue... I don't really understand why companies are allowed to hold on to patents as long as they currently do. Intel's x86 was introduced in what? The 80s? Rambus' memory patents are from like 10 years ago...

Why the hell are these still relevant?! The patent system is a freaking joke.

I guess until you patent something, you won't understand.

There are companies out there that just invent stuff and licence out the know-how in order to make money... that's their revenue source.

Take away that source and you can kiss those companies good-bye.

Well at least Nvidia can get along with making more video cards now. they might even have extra money that they had stashed away for the lawsuit. lol.

Qimonda, the manufacturer for XDR for the PS3, got bought by Micron, one of the companies Rambus has repeatedly attacked. I doubt Micron has much interest investing in RDRAM or XDR. RBMS's growth rate and earnings have been in the negative for the past 3yrs. These guys are nothing more than ambulance chasers of the tech industry.

I think he was referring to the fact that patent holders can refresh their patents in far too many instances than should be allowed. Patents are starting to kill innovation, as opposed to encourage it when applied too broadly... Technology is evolutionary, not revolutionary in most cases.
