feedmegin posted:Again, cores aren't magic. Look up Amdahl's Law. You can't 'optimize towards massive amounts of cores' if the task you are attempting to complete is fundamentally sequential. Isn't Amdahl's Law overshadowed by Gustafson's Law? Which basically states that, given a non-fixed size of data to be processed, Amdahl's law is irrelevant? Admittedly, I dont know enough about this (because math) other than what I've read on wikis and some light research. But it felt worth mentioning

NihilismNow posted:5 year old i5 2400's can deal with this fine. If anything with the move to more VDI/SBC based platforms i see corporations taking computing resources away from end users. The worker who used to have a quad core desktop with 8GB RAM now gets a VM with 2 vCPU's and maybe 5 GB RAM. Only people who can justify it get to keep their physical machines. is there a "bring an old quadcore from home" option?

I'd think the i7 6700 would get you better performance stock than a ~15% faster overclocked 6600k. And you wouldn't have to mess around with overclocking/higher temperatures. If the cost is the same why not i7?Otakufag posted:1- For those of you who have upgraded from a 2500k to a new skylake: can you feel noticeable differences when playing recent games or doing other windows stuff?

Eletriarnation posted:I would say that a typical overclock is more like 30% over the stock base clock than 15%, (3.5 >>> ~4.4-4.6GHz) and in the absolute best case when you can load all 8 threads HT will be a 30% or so (sanity checked myself here) benefit. When you can't load more than 4 threads it gets you nothing. I don't think the non-K 6700 is a good deal for anything ever unless it's a system that can't OC. I was thinking that since the i7 6700 has a 4ghz boost clock, then the 6600k would only get 4.6 easily so that's 15% more clocks. The i7 seems more future proof but, people gonna do what people gonna do

EdEddnEddy posted:Hearing "Auto Voltage" is giving me plenty of OC related triggering. (Auto sometimes can run it just fine at "stock voltage" levels, some boards however can spike things to 1.5v+ though, also watch out for High LoadLine Calibration settings!). I guess that is to blame for the "ease of OCing" the new K series, but it sounds like few of you have really dialed into the deep parts of the bios settings that board makers like ASUS put in to really get the chips dialed in at a higher speed. Yeah I have no idea where the auto voltage fad came from, but back when I was first learning about OCing it was a no-no. It's just one extra setting to change with one rule, don't go over 1.x voltage. From my experience, auto voltage sets the voltage way higher than it needs to be

BIG HEADLINE posted:Keeping the CPU at max speed all of the time hastens electromigration, which is a fancy way of saying that you're making current/electrons flow too quickly through the transistors, and eventually something has to give. I don't think there is any solid evidence to support this. As long as your CPU isn't heavily - to - the - max OC'd 24/7 then it will be fine. Yeah your power bills will be higher if it stays at 4ghz all the time but it's not going to kill the chip early.

Maybe Intel just put a halt on increased performance chips so the rest of computing could catch up. Software/multi-thread improvements, ssds, higher bandwidth ram all offer better performance gains to the 5 year old 2500k than a processor with twice the IPC.

Pryor on Fire posted:It's amusing how quickly the conversation has changed in the past few months. It's been what, seven? years of a steady drumbeat of "physics is hard! we hit fundamental limits! can't do any better you're just not smart enough to understand!" while Intel is just lazily minting money. Seven years of pointing out that the "physics" argument is utter horseshit and getting dogpiled/downvoted/whatever for it, or for daring to criticize Intel. They have a million PhDs, you think you know more about chip design than them? How dare you. maybe take a break from the interwebz for a while. i think you might be conversating with yourself

I feel like we're getting into the extreme worst-case scenario for someone who needs to back up their data. I mean, if you're lugging around a library of congress-sized library, then yes maybe you should take a little time to make backups. Otherwise the cloud is a reasonable alternative to backups. what the hell were we talking about again?

Intel seems to have rushed this launch. The only motherboards available are the Z series which are not necessary for an 8400 chip. Next year there should be the B/H model boards that will be more suited to the 8400 processors, at a lower price.

Doesn't it hurt Kaby lake sales too, though? Oh well, I guess Intel can take a sales hit as long as it affects AMD too. Boo

Has there been an IPC comparison with the last few generations yet? IIRC Skylake/Kaby lake had almost 0 IPC gain at all. I think they have to move to 10nm for actual gains, but I've been wrong before

So, the thing about water cooling is: it's great at absorbing heat and can absorb a lot of it. But when it gets to a certain point, the radiator won't be able to dissipate it fast enough, which will lead to normalizing temperatures that are somewhat similar to air cooling. My advice is to not stress test your half-decade old CPU for long a duration

Paul MaudDib posted:Icelake is a gamble. Die shrinks often hurt the overclock you get (see: Ivy Bridge, Broadwell). Intel has obviously been strugglebussing with this node, do you trust that just because Intel says the node is 10nm+ that they actually hit the same clocks as 14nm++? Those who have moved on to 10nm (pretty much just Apple via TSMC) are having decent IPC gains, 20-30%. You're making a lot of negative assumptions about Ice Lake based on little evidence. The real question is, how does AMD respond to Coffee Lake? and will it put pressure on Intel to release Ice Lake early like they did with Coffee Lake?

Agreed posted:Got my 4770k to 4.4GHz at 1.28V right now, input voltage of 1.9V, and it seems quite stable. Using an Asus Z87 Sabertooth board, it has been straightforward enough to overclock. If you set the voltage to 1.9 and are only seeing 1.28 I would be worried that the reading isn’t accurate. Do you know about LLC and how it works?

Paul MaudDib posted:it is completely bonkers how everyone has gone all-in on 3D stacking without any idea how to cool it, everyone’s just sure it’s the next big thing. The solution could be as simple as "dont run this at 5ghz". IPC should go up since everything is on the same substrate, so the question is will it go up enough to make 2ghz chips match performance of their high clocked counterparts

Indiana_Krom posted:Bringing DRAM closer to the die is for bringing data closer to the CPU so it can wait less and work more, which means it will also consume more power. Stacking everything together will definitely make cooling and power consumption worse in pretty much every way, because it sticks more power consuming and thermal dissipating components in less space than ever before and helps them all work harder besides. I hope you don't think that they plan to make these chips 95w TDP. 7nm doesn't scale well with high power usage. They will try to target the optimal spot of the efficiency-curve. More likely we'll get similar performance of today's chips but at 15w or 7w so it can be passively cooled and tossed in a tablet or surface pro

PCjr sidecar posted:Yeah that’s what I’m referring to. 30% higher base clock for 40% higher TDP relative to 200w part. 7nm may or may not scale well but its not going to stop vendors from putting as much in as possible. Original comment was referring to 3D stacked dies using 7nm. There would be no way to cool a 280w part (well, eight 35w parts) in a situation like that. So I was simply stating that Intel would probably try to hit peak efficiency curve rather than max out the clock speeds. But yeah look at the efficiency on those 8-core chiplets on EPYC. From 65-95w tdp @ 3.6-w/4.4ghz boost to what, 25w at 2-w/3.3ghz turbo?
