I don't see any reason to want one of these at all, especially a 965- not for HPC, not for home computing, and definitely not for business use. With the G7's economies going the direction they are as of late, I don't even see where this will sell well to the narrow niche of spoiled children.
You're not the target market for these chips. Intel doesn't care that you're nonplused and unwilling to spend ~$,1000 on one of these new CPUs. Intel is also well-aware that plenty of people can do everything they need with a Pentium M. For those of us running applications that thread well, though, and need lots of bandwidth, it's going to be a beast. There are things at work that I wouldn't even bother trying to run on my current workstation that Nehalem will eat up. How's that for a reason to want in on one of these? Going from 'not able to do it' to 'able to' is as big a performance boost as you can get.
When the chip market is moving to Atom-sized margins and good enough for web surfing performance, I can't see how a chip that isn't a ten-fold leap in dual-threaded performance is going to be a success. Anything more than two threads at a time seems to be beyond most application developers, even though CS programs been teaching non-blocking, multithreaded I/O, for two decades.Some
of the market is well-served by Atom-powered boxes. And what novel CPU tech has provided a ten-fold performance leap over the last generation?
In the grand scheme of things, 99% of the products launched around shouldn't concern me; I've got an old slow 2Ghz PC that will serve me well for the next time, and I really appreciate the damage everyone of us does to the environment when buying new products one actually don't need. I won't upgrade to Core i7, nor would I buy and LCD TV as long as my old CRT does the job well. For me, the Core i7 is interesting solely as a technological leap, not as something I would potentially buy.
Everything about our lifestyles damages the environment. Your CRT isn't exactly innocent as the driven snow. It may be a sunk environmental cost now (not really, because some day it needs disposal), but it still has a footprint.
Go look at the 'Task Energy' numbers at techreport. The i7-940 beats everything else they tested in joules consumed over the render period. The idle power draws for the 940 are middle of the pack that TR tested, but it's worlds better than my current workstation.
I could also point out that Core i7, like the latest Core series CPUs, are manufactured using a lead-free process.
But you're not the market for this chip, and your needs do not represent the needs of all computer users. Fuck, 99% percent of us aren't the market for this thing. It's aimed at workstations and servers. If it wasn't for my job, I wouldn't care about it either, other than for the 'Ooh...' factor. Nehalem just isn't aimed at the mainstream or low-end/low-power market now. Nehalem-based chips for laptops aren't even due until next year. That doesn't mean the architecture isn't interesting or impressive, though.
