DDR3 Isn't Worth The Money - Yet 120
An anonymous reader writes "With Intel's motherboard chipsets supporting both DDR2 and DDR3 memory, the question now is whether DDR3 is worth all that extra cash. Trustedreviews has a lengthy article on the topic, and it looks like (for the moment) the answer is no: 'Not to be too gloomy about this, but the bottom line is that it can only be advised to steer clear of DDR3 at present, as in terms of performance, which is what it's all about, it's a waste of money. Even fast DDR2 is, as we have demonstrated clearly, only worthwhile if you are actually overclocking, as it enables you to raise the front-side bus, without your memory causing a bottleneck. DDR3 will of course come into its own as speeds increase still further, enabling even higher front-side bus speeds to be achieved. For now though, DDR2 does its job, just fine.'"

So an older guy came and said he wants them to build him a system. He was pretty explicit that he really doesn't want much more than to read emails and send digital photos to his kids. You'd think entry level system, right? Well, the guy behind the counter talked him into buying a system that was vastly more powerful than my gaming rig. (And bear in mind that at the time I was upgrading so often to stay high end, that the guys at the computer hardware store were greeting me happily on the street. Sad, but true.) They sold him the absolute top end Intel CPU, IIRC some two gigabytes of RAM (which at the time was enterprise server class), the absolute top-end NVidia card (apparently you really really need that for graphical stuff, like, say, digital photos), etc.
So basically don't underestimate what lack of knowledge can do. There are a bunch of people who will be just easy prey to the nice man at the store telling them that DDR3 is 50% better than DDR2, 'cause, see 3 is a whole 50% bigger than 2.
And then there'll be a lot who'll make that inferrence on their own, or based on some ads. DDR3 is obviously newer than DDR2, so, hmm, it must be better, right?
Basically at least those teenagers you mention read benchmarks religiously, with the desperation of someone whose penis size depends (physically) on his 3DMark score and how many MHz he's overclocked. If god forbid his score fall 100 points short of the pack leader, he might as well have "IMPOTENT, PLEASE KILL ME" tattooed on the forehead. At 1000 points less, someone will come at a door with a rusty garden scissors and revoke his right to pee standing. So they'll be informed at least roughly what difference does it make, or at least if the guys with the biggest e-penis are on DDR2 or DDR3.
I worry more about moms and pops who don't know their arse from their elbow when it comes to computers. Now _normally_ those won't go for the highest end machine, but I can see them swindled of an extra 100 bucks just because something's newer and might hopefully make their new computer less quick to go obsolete.

Does it exactly matter if your computer can do 6GB/s, or 12GB/s? 14GB/s? Where does it stop? And even then, that's mostly theorhetical, particularly in the case of DDR2. But a very important distinction is that so many memory accesses are of very small to small size. On basically all of those accesses, the memory request will be served in far less time than the latency will allow the command to return and allow another request.
Way back when, Intel motherboards tried out RDRAM for its 'higher end' boards, and the Nintendo 64 also started using it. Both were fairly large fiascos, in that sense, with more or less all technical reviews noting that the increased latency more than cancelled out the improved bandwidth. Now we're looking at DDR3, with far higher latencies than classic RDRAM for a relatively minor bandwidth improvement that only extremely large memory requests (such as applications that would theorhetically be done in an extremely large-scaled database and scientific research).
It reminds me acutely of the early 'Pentium 4s'. A 600Mhz Pentium 3 could beat up to a 1.7Ghz Pentium 4 in most applications and benchmarks, and the (rare and expensive) 1.4Ghz Pentium 3s were real monsters. But people kept trying to tailor benchmarks to hide that, so people would buy more product.
Overclocking has also generally demonstrated that overclocking regular 'old' DDR1, while a bit pricier (mostly due to the virtual elimination of production nowadays, though), scales better and also has far better numbers than DDR2 and the like. DDR600 equivalent is extraordinarily zippy, and (of course) real-world latency is also absurdly low.
It makes me feel like the 'governing bodies' here have really let people down. Instead of trying to standardize on and promote what's best for general computing, they're trying to push a greater volume of merchandise that has no meaningful improvement, and in fact usually a notable decline, over what we've already had for years. The bottom line for them is money, and that's just wrong to put their own pocketbooks over the long term well-being of computing technology and the needs of the consumer.
