I skimmed over all the replies, so if this has been brought up or debunked, forgive me and correct me. This isn't an ego trip.
First off, how many people here have ever run server hardware or at least dual socket mobos? (I think they are one in the same though till the 4x4 is released.)
As you can see by my tag, I'm running a dual socket system, and might I add, slow by most standards. Although it appears slow, I get a very good computing experience, including gaming (thanks to a good vid card). Multitasking is not an issue.
Now to my point. Each CPU will have its own memory controller for ram. Won't this basically double the throughput of data since there's 2 independent controllers for ram?
Even if C2Q is "faster", it couldn't handle the output vs 4x4 w/ 2 memory controllers (assuming the same amount and type of ram for a fair comparison). I guess its not a straight forward comparison of speed.
One other issue I'd like to bring up is cooling. I asked a question a while back (though no one remembers since it comes up now and again) if CPU makers will start producing 1st party liquid cooling set ups for CPUs. They've started doing this with video cards (at least in terms of buying the card out right), so why not CPUs?
At 125 watts of heat per CPU, thats a lot of heat put into the case. Even though I plan on doing liquid cooling, I wouldn't want to air cool these since you'd need pretty good air flow although I can see how it easily can be done. It'll just end up being a little loud which I don't want.
Right now, I have 2 prebuild liquid cooling systems (1 per cpu) to cool them down. Its probably overkill, but I think that if you're cooling 2 cpus and 1 or 2 GPUs, you'll need a decent size tank so that you will have cooling fluid avalible at all times. Otherwise, I wouldn't see too much trouble in building a cooling system, although for many of you, cooling 2 cpus will be a new adventure.
I guess we'll see if the 4x4s are worth it in about 2 weeks. 😀
