[Rambus] XDR™2 vs. GDDR5 - The Future Of Memory - Page 6

post #51 of 63
I'm not sure if XDR2 will be used in practical applications. Some games utilize the bandwidth available on graphics cards today.

The only real advantage I saw with XDR2 is how much more narrow the interface can be. Sure, less power at the same bandwidth, double the bandwidth at the same power, yada yada yada. If XDR2 doubles the bandwidth of GDDR5 on a 256-bit interface, it will have some applications in future graphics cards. At what cost to the consumer? I haven't a clue. I think it might behoove Intel to tinker with the technology since they're newcomers to the discrete graphics card market. If they can make an affordable solution at a competitive cost, ATI and nVidia might make the jump as well.

Of course, this is all speculation. There's no telling where things are headed. But if XDR2 isn't affordable enough, we'll only see it used in systems like the PS3. Which oddly enough doesn't use XDR for graphics, only for system memory.

*sigh* Larrabee is designed on parallel processing. Therefore on board bandwidth between Larrabee and Memory will be a limiting factor.

Can't wait to see this commercialized...

Oh brother, here we go again with Rambus inventing some fantastic memory that will never be accepted. Then they'll sue some other companies for patent infringement so they can stay in business. I don't know if you guys have looked at this lately, but 1GB of RDRAM 400MHz(!) still costs around $100!! That's for a computer that came out in 2002...

The point is, they have some great memory;always have, just can't seem to be farsighted enough to realize that volume=more money. You can't sell volume on more expensive components. It's like Nvidia expecting to outsell ATI with the GTX280. Not gonna happen.

I always seem to link ATI and Rambus and AMD (and companies like this) together. They're SO close to being successful...if they would just do this one thing they could own the market....then they don't. Rambus is a little different though, they think that they should force everyone to pay what they say because they control the patent. Hasn't really worked too well for them.

I don't see XDR2 being successful, mainly for the reason that Rambus is suing (or has sued) Nvidia for patent infringement already. I doubt that Nvidia is going to be thrilled dealing with Rambus (or would even be able to work out a deal where they could make money using XDR2).

please notice that xdr2 ends at 2015 gddr5 ends at 2009 doesn't show a stat for gddr 6 or 7 or whatever is going to be the next standard

Because its RAMBUS, overhyping and then failing to deliver is in their company DNA. Don't worry, they'll survive through lawsuits for a few more years yet.

Speaking of which, they currently have an ongoing lawsuit against Nvida in which they will probably make some kind of income in the form of settlement. Then again, perhaps they might try to work in a deal in which Rambus would drop the lawsuit in exchange for Nvidia using some of this XDR2...

What does this matter? XDR already outperforms GDDR5 so why would anyone be led to believe GDDR7 would beat XDR2?

Yeah, that'll be the day, I think RAMBUS would be quite satisfied to burn bridges with every company in the industry so long as it means they stay in business whilst not needing to produce any products.

Touting XDR2's performance in graphical applications whilst simultaneously taking the world's largest graphics company to court speaks volumes.
