k-uno posted:A quantum computer is capable of solving certain classes of problems vastly more quickly than any possible classical computer, precisely because of the superposition principle. The speedup from a quantum algorithm ranges from polynomial (searching a non-ordered list of N elements for a specific value takes ~N queries on a classical computer, versus ~N^(1/2) on a quantum computer) to sub exponential (factoring large numbers is polynomial on a quantum computer, sub exponential with the best known classical algorithm). The hand-wavy reason for this is that the superposition principle allows you to do calculations with an insane degree of parallelism. Imagine that you have one bit, and you want to operate with some function on both 0 and 1. In a classical computer, this means you have to run the function twice, but in a quantum computer, you can set a qubit (quantum bit) to be both 0 and 1 at the same time, and operate on both values in a single function call. For one bit, this is a factor of two increase, but for, say, 32 qubits, you can arrange a superposition of all 2^32 ~ 4 billion possible configurations simultaneously, and operate on all of them in one step. Now, the catch is that the result you get when you measure the state at the end of the algorithm is random, but if you choose your algorithm cleverly, the "wrong" configurations can interfere destructively making the random result heavily biased toward the problem solution. So, magic. Got it.

Lowen SoDium posted:The console CPUs currently are not being utilized as well as they could be. AMD's Jaguar is pretty low performance, so developers have little choice but to multi-thread as much of their workload as they can to get as much performance out of the consoles as they can. I think we can expect to see some of this work show up on PC ports eventually. The choice in CPU seems like an odd one. Say you were building a PC. Is there any particular task you'd choose that particular CPU for?

I could give a gently caress less about the ones with motors that raise and lower the surface on cue, but the ones that can house two different systems side by side would be nice. I would love to do my next build as a desk case but yeah there don't seem to be any under a thousand freaking dollars

The rumors point to the answer being almost definitely a no. Allegedly, there's very little OC room. But the issues might be thermal rather than chip limits so maybe watercoolers will take off here.

DrDork posted:I'd be easily persuaded that it was based on some fairly reasonable 3rd party cooler, but it doesn't say. Either way, AIO's cooling big chips better than air is pretty normal, so I'm really not seeing anything new or unexpected here: big-rear end 10C chip under reasonable loads hits in the 70-80's under reasonable cooling techniques. Nothing new there. Now, if the 10 core chips could hit those clocks, I'd probably buy one. But given the TIM issue I suspect that many cores running that strong will fry, if those clocks are even possible. And I'm not really willing to delid a $1000+ processor.

B-Mac posted:I won't lie that 6c/12t CPU will be real tempting if 1. Coffee lake will support the z170 and 2. MSI updates my bios to support it. Particularly if it manages the Kaby Lake ~5ghz clocks with some reliability. I'm skeptical of its thermal limits, though. It's 50% more work being done in the same area. Kaby Lake is already hot, and you know full-well Intel is going to keep using that freaking cheap paste.

eames posted:If Intel cares about X299 they should work on a 6/8/10 perhaps even 12 core Coffee Lake X lineup with the "old" ringbus. Shouldn't the IPC be about the same as Skylake/Kabylake? If you're able to keep thermals under control and clock the SL-X chips up to the ~4.5-5.7ghz range, they should do about as well as their 4-core mainstream counterparts in single-thread while obviously having the extra cores for multithreading like a champ. ...so if you're willing to delid a $1000 chip and put it on water you've got a solid operation.

Scarecow posted:Its going to be gimped as gently caress due to intel not soldering their loving ihs on If this thing is basically just six kaby lake cores in the same package, we're talking 50% more heat output. Going to be trouble. Delidding will continue to be popular! I have the tool for 1155/1151 so I expect it will work for these chips. If Intel has given us a 6-core chip that can clock to 5ghz with Skylake's IPC (as opposed to Skylake-X's regression) then I am all over that poo poo. edit: especially if I can still use my z170 motherboard.

Koramei posted:There aren't any crazy deals for Black Friday right? I hadn't planned on it, but I ended up buying half a computer, so I figure I might as well get the other half too, but I'd like to look into it a bit more rather than scrambling to get everything ready on the final day of the sales. The really crazy deals are usually older equipment they want to dump. Can't hurt to check Newegg, but if you're looking for current gen stuff don't expect anything earth shattering. New stuff is substantially faster, yes.

gradenko_2000 posted:In pretty much all overclocking videos I've seen that work with liquid nitrogen, people seem to build like a receptacle on top of the CPU, and then they have a cooler or a tumbler full of nitrogen, and then just pour the stuff straight onto the CPU. Obviously the stuff evaporates, so you have to keep pouring more and more in over time, and it's a temporary thing. If it's a closed system, ultimately all the heat needs to go to atmosphere somehow. Atmospheric temperature is way, way too hot for nitrogen to stay in liquid form, so you can't just use a radiator cooled by airflow. (thermodynamics, and whatnot) So you need a cooling system capable of producing temperatures low enough to condense nitrogen. So... you need to have the machinery that produced the liquid nitrogen in the first place, basically.
