<< Nope. Rdram has a 16 bit data path. PC-1200 will have 64 bit effective data path under application. I didn't know Dual channel DDR was available right now? >>



yep, my bad, little calc. mistake. :) Dual channel DDR will come. If they can do it with nForce, there's no reason why it couldn't be done for the P4.

What's that PC1200 you're talking about, new Rambus @1200mhz? Could you explain the 64 bit under application... That would mean 9.6GB bandwidth, which would be pretty nice.

Yup. Check this. Quite a ways down the road indeed but none the less, PC-1200 with a 64 bit data path would be a fantastic serial memory product. It would actually be running @ 600mhz double pumped...

Majewski9 I don't appreciate you calling people idiots just because they buy a p4. The p4 is alot faster in multimedia thant the athlon and that is a fact. Quit blowing down other peoples hardware to beef up your own. If your so called great hardware is good then it will speak for itself! Have a nice day!

&quot;The great benefit to RDRAM is the bandwidth. RDRAM currently offers 3.2 GB/s. That's a lot more than DDR SDRAM. One of the reasons it can offer so much more bandwidth is that it's dual channel. This explains why you have to have two RIMS to make it work. The drawback to RDRAM is that it's very expensive compared to SDRAM. You can get about twice as much DDR SDRAM for the same price. At Crucial, a 256 stick of DDR RAM will run you $61.00 compared to $128 for 256 of RDRAM.&quot;

Dual-channel DDR (such as nForce promises) will be a match for RDRAM. On top of that, RDRAM has inherent latency issues (high). The P4 core is designed to &quot;hide&quot; or &quot;mask&quot; these latencies using a long pipeline and various other optimizations. Nonetheless, talking about and comparing only the TYPES of RAM, DDR is a far better choice. Medium bandwidth with low latency -- superior, IMHO, to high bandwidth AND high latency. Of course, if your only object is to impress your buddies with high Sandra RAM benchies, RDRAM just might be for you. :) (It's also important to consider that the vast, vast majority of software depends on lower latencies rather than maximum bandwidth.)

And certainly everyone has something to say about the company (or is the group of lawyers masquerading as a company?) :D

&quot;Pentium 4? Are you an idiot or do you like throwing away money on inferior products? Get an Athlon and wait for Nvidia Nforce! Yeah and has anyone seen the benchmarks for the SIS 735 chipset? That is a much overlooked cipset!&quot;

Why do these threads ALWAYS turn in to a flame throw? I'd like to see a serious discussion about the MEMORY ITSELF, that is, RDRAM versus DDR. Each has advantages and disadvantages in a particular environment. So far all I've seen is flames thrown and some misinformation (like the clown who insinuated that RDRAM would be superior in SMP / Server environment -the high latencies of RDRAM are a bad match for such an environment.)

Let's keep on-topic and discuss the MEMORY, not P4 vs Athlon or what have you.

p4's suck @$$ so get a athlon. If your getting an athlon, you gotta get ddr ram cuz sdram sucks major monkey

<< geez, just select &quot;disabled&quot; in the BIOS, it's not that hard. I don't think many people in here are waiting for nForce because of it's graphics capabilities. >>



Yeah I'll just rip out the video and sound and sell it back.

This is the reason why I tend to stay away from General Hardware nowadays.

eviltoon:

Wait for a couple of months until Northwood hits the market.

Via claims that its DDR-based chipset outperforms Intel+RDRAM combo. I doubt that there is any truth behind this, but if it turns out to be the truth, then you might want to consider loading your new P4 with 1GB of PC2100 DDR SDRAM. :) Unless you really really need the higher bandwidth of RDRAM, that is.

Otherwise, stick with PC800 RDRAM with the P4. I really think you should stay away from Willamette P4, though.

Can you guys with your childlike comments have a serious discussion without the childlike behavior, I think not.
For the flame throwers, grow up or please leave.
