General computer talk/advice

Its because they are running into quantum physics issues by going lower than 14nm.

 

7nm is the predicted limit, but yes advancing towards 7 is going to get harder and harder.

 

yeah, i adjusted in the registry to slow the clockspeed bumping, saves battery more (https://nmilosev.svbtle.com/hidden-power-settings-on-your-windows-81-tablet) really? 2 days on your old i7, but reviews on the tablets say the battery life is rubbish and its like only 3.5hrs (see ASUS Transformer 3 Pro). I know Atoms get high battery life, but i didnt realise you could get multiple days of note taking out of it, my Atom Tablet has connected standby issues (bloody windows 10) where there is a chance that it drains fast (CPU doesnt shut down) and so you come back to a dead tablet (or nearly).
Meh, tbh i like the quad core atom thing, and i dont blame them, MTK does this with Cortex A53s in a quad core setup at low clocks and is decent. Core M CPUs are good for premium segment, but we need replacements for the upper end tablet section (like idk £400) which would benefit from a good Atom, one that is high clockspeed when it needs to be and strictly low clocks when it doesnt. (Windows needs to be far more stringent on clockspeed in my opinion, take Microsoft Edge, when i am just scrolling the CPU is at max turbo clock, I can drop this using throttlestop to around 800mhz and it still is fluid 60fps scrolling. But throttlestop doesnt go below that properly (doesnt set voltage right).

 

The reason MediaTek processors are pretty much the cheapest and worst performing mainstream processors on the market is because they have too many cores. Ofc All Winner CPU's are worse but that ain't something to celebrate being better than.

Note that when I say 2 day I am not talking about screen on time. I am just talking about general usage. With the I7 that also means having a really deep sleep state where it pretty much powers off overnight, so you have to wait for it to power back on in the morning but everything resumes correctly.

You can actually get cheaper core M3 tablets such as the Cube I9, however when buying cheap devices like that you never really know how the warranty will pan out.

 

@Michaelflat Atom cpu's are derived quite directly from pentium 3 architecture. Core chips were also derived off this but more heavily modified, where Atom stays true to the pentium III architecture a little better. Pentium 4 was scrapped entirely after 05~06 and only derivitives (sic?) from such were junk Celerons with awful ability. So yeah, atom might be a little slow, but it's surely capable if it has enough clockspeed. Truth be told, 2ghz chips are fine (if they're even that fast!!!) for web browsing, but not for any cpu-intensive software.
Generally you can buy an upgraded battery for your device. Try not to cheap out and go generic, or it may explode or otherwise become a blazing inferno. This way you can have a powerful long-lasting device. Battery use does degrade it's longetivity over the course of a few years.

Try shutting off SMT on your 8-core Ryzen and benching your favorite games. It will cool it off a few C and it will devote more resources to the task at hand. You will have an 8 core 8 thread chip not a 16 thread chip, however, few apps take advantage of more cores than that. Beamng.drive would be a good place to start checking performance. Some games noticed a 20~30% boost when doing this, others noticed performance loss of up to 10% possibly more. YMMV. Do let us know how it goes though!
I'd love to see some Beamng.drive 8-car performance numbers though.

 

I don't have Ryzen, but I do agree, that helps those another thing I have read is having only 4 cores on, but what I have seen as an average figures of doing that is around 10% increase, not sure if disabling SMT will add to that or if disabling SMT will be giving all the boost one can have.

Quite many seems to think that it is Win10 bug, in Win 7 performance seems to be better at least based on benchs I have seen, so it would be easy to agree that there is some issues with modern Windows and that chip, also MS has been said to be working on patch to address the issue.

With new stuff quite often best tactic with limited funds is to sit back and see evolution in progress, eventually most of the new things are going to improve and give more value to spend money, after new things mature a bit.

There was other thread where some performance figures were posted (1800X, 10 * D15 @100fps, 10 * T65 @79fps) https://www.beamng.com/threads/beam...the-game-well-enough.36807/page-3#post-559265 but you should not that tests are done with settings that allow most of vehicles, with my i7-6700 I can do 8 vehicles around 40fps with similar setup https://www.beamng.com/threads/beam...the-game-well-enough.36807/page-3#post-557026 like posted here (R7 1700 11 T75 ~30fps) https://www.beamng.com/threads/beam...the-game-well-enough.36807/page-3#post-557006 which I think shows how there is something in Win10 and SMT that slows things down.

So you can see how nicely BeamNG and Ryzen can work together when shadows are off, even with SMT bug, but big question is how it will deal with lighting quality high and shadows on like in my Off road Roamer tests, which has 12 lights creating shadows with lot of objects in East Coast USA town scene, that makes very hard single core performance test that only Nadeox so far has shown tested with comparable settings. i7-6700 does slow down close to 20fps if dynamic reflections are on, without dynamic reflections around 30ish fps, while i7 4790K 25ish fps and I have no idea if Nadeox had dynamic reflections enabled or not.

That is limit in Torque 3D currently, at least that is what I got from Nadeox's comments, shadows just are so hard on CPU currently, so that is going to be one thing we have not seen from Ryzen yet and so overall performance is bit of mystery.

My estimate is that overclocked to 4Ghz 1800X is quite same as i7-6700 on that extreme shadow test, but this is based solely on Cinebench score, there can be other variables in play which I don't know about yet.

Then overall performance is something different again, it is one thing to have GPU that performs and CPU that performs, sometimes they don't give best performance paired together, sometimes motherboard and chipset affects to that fine balance of best performance from system, so that is another bit of variables that needs lot of testing until one can say what performance might be on one's own use case scenario, sometimes (like currently presumed with Win10) software is variable too, so more data is needed.

 

The R5 1600X is looking pretty neat now that the R5 series is out of embargo and no longer rumours. $250 for a 6 core 12 thread 95w tdp 3.6 Ghz - 4Ghz boost CPU. Unlocked multiplier like all other Ryzens so far.

Launching April 11th

Hopefully per core per megahertz performance would be same as with R7, if that R7 overclocks to 4.5Ghz, then it would be really good for BeamNG, but let's see, same time I hope it to be something of such greatness (there would be no point of getting Intel then as single core performance would be at par and you would get extra cores while still paying less), I'm afraid of something that FX was, future tests will be interesting.

Certainly will make some boost to markets.


I have been waiting quantum computer for a long time, but I'm afraid I run out of years before those come to my price range.

 

The problem with quantum computing is that it will likely be unable to run traditional software (without compatibility layers or emulation) since it is a massive architectural change. They are totally different in how they function and last I heard they weren't faster than a traditional CPU for all workloads, only some.

Its also very possible that quantum processors may end up being co-processors just like graphics cards that sit along side a traditional CPU in order to accelerate certain specialised workloads.

Maybe they will be awesome, but personally I don't buy into the hype of them at this stage.

If it takes Intel several years to design a CPU iteration (since they work on multiple generations at the same time) its going to take a lot longer to design a brand new architecture and that is only after things have been researched adequately which they still haven't.

 

Everything of that is pretty much like from my thoughts, I'm sure that at some date those will be standard or something new which we don't know about, but probably only when worms have eaten my corpse. I can't even remember how long ago I first read very hyped article about quantum computing, but quite while after that it was written it is impossible, only at recent years it has become actually possible I guess, there was news about some breakthrough not very long ago (it can be anything from yesterday to 5 years or 15 years with my memory).

I think it was at PS3 launch time that some article explained how at launch of PS2 games could use only fraction of computing power, but during the years they managed to optimize games so that far more complex games were possible, if we can't get faster single core performance, I guess it is time for software to stop relying so much to it, which of course has already happened quite a lot, but there still are many pieces of code which are not using any kind of threading.

 

thats normal for consoles that they find new ways of utilizing the power like the ps3 where they didnt know how to utulize it the right way at first

 

More true for the PS3 than most consoles due to its cell architecture which still to this day barely anyone actually understands

But since the xbone is basically a Win10 PC they are gonna struggle to find new ways to get extra performance due to it already being a tried and tested platform. Same goes for the PS4 but maybe to a lesser extent because it has less explored OS and rendering system.
I guess the unified platform will allow devs to spend more time testing and optimising rather than porting, but it will likely mean quicker projects rather than spending more time.

 

I remember when the ps4 was brand new one of the developers said that the ps4 is already at the limit and 1080p 60fps is imbossible to get with it

 

Thanks for this, this is helpful and informative. As knowledgeable as I try to be in hardware, I did not know they were coming out so soon!
This will be the mainstream/gamer chip series to get. It's looking good to me.
I sure as heck won't be paying for another E-Z-BAKE intel quad core with HT for 300~400$.
I have a 4790k and the 7xxx series 3 generations later is the first one to finally 'surpass*' it.
*it's up to 20% faster give or take, on encoding due to faster ram speed, and newer instructions, where-in most games it's roughly the same...
So yeah, I'd like to snag a 6-core cpu. As long as I can get it on par per-core with my 4.0ghz 4.4 turbo cpu, it'll be a no-brainer to get a 50% upgrade. Can't afford to lose IPC or FPU performance though. If these overclock to the same speed as this, it'll be a clear win.
FYI this rotten hot-box 4790k is fast but it's surely belching out more heat than it or I know what to do with, even at 4.4ghz.
If you don't have the thermal paste just perfect, it's E-Z-BAKE for you!
Who wants some thermal-throttling cookies!?

Paid too much for this, but it's worth it

 

so i have an old compaq presario a916nr, i put a random old hard drive in it and installed linux mint, however the cpu fan seems to have gotten ruined at some point, as it tries to turn on at startup of the pc, but it fails, now once it finishes that initial post, i can blow into it and it'll force start it, but then once the tempurature is at a low enough point the motherboard shuts the fan back off, which is of course a problem as it can't turn it back on, and it ends up overheating and shutting down if i don't force it back on soon enough, i figured i'd just use fan control and have linux keep it on forever, however pwmcontrol sys there's no pwm capable sensor modules installed, and fancontrol just complains that it can't load a valid configuration file, so i was wondering if there's anything i can do to fix that, or if i need to replace the cpu fan or what's going on? (reason for linux instead of windows is the hard drive is dying, and it's far gone enough that windows is unable to install, it gets stuck at expanding files at around 56%, or it'll error out with 0x80070057)

 

Perhaps cleaning the fan might help in order to lower its resistance. Failing that if you feel like bodging it disconnect the fan and attach it to somewhere that will provide it with constant power when turned on, perhaps you have a spare storage power connector etc.

 

At old days, we removed the back side sticker of the fan and dropped bit of oil to fan's bearing, sometimes disassembling fan blade part from the unit as there was a clip under that sticker to hold it together. Oil gave little bit more life out from the fan. These days fans are so many and low cost that I haven't bothered, but with laptop fan that might help to get it going again.

One surprise I got with laptop fans was that exactly same sized unit was used in 2009 HP than with 2004 HP, but in 2009 HP it was yearly replacement, putting years old unit from 2004 HP to 2009 HP made it last seemingly forever. Different part number as there was very slight difference in fan/heatsink unit, different price too. So, if you can't find new fan for the laptop, there is possibility that some newer model fan might fit.

Can't even remember how fan was fixed to rest of the cooler in laptops, but replacing just fan to cooler unit might be possible too, that is just something I don't think I ever did, finding just a fan might be easier than out of production cooler.

 

I read /var/log/authlog (logs were rotated yesterday) on my NetBSD server, and I found about fifty (failed) unauthorized SSH login attempts from Eastern Europe and China. What gives?

 

There is bit higher percentage of people who can't find jobs after education or/and generally respecting others stuff is not considered as an value?

Alternatively, during communism, everything was thought to be free for grabs and during generations it has become new normal?

It could of course be that their security is enough weak that hackers from some other places get control of their stuff easier, so some kid in western world uses them to hide their traces.

Organized crime is also possibility.

I like to have several firewalls these days, just to imagine that only few years ago, you could have computer connected to internet without any kind of antivirus or firewall and there was no real danger of viruses or any other issues, everybody did it, only about 19 years ago or so. Around 2001 things started getting to worsen and fast, general public had got to net in masses and all kind of criminal activity increased rapidly. 1998 internet was completely different, you could get by without any kind of protection.
These days, it is not really safe to rely only one firewall, scripts have to be kept off when doing research and so on, there is more scams and click fishing than actual content or so it feels at times when trying to find something.

Missing old days when you could set up anonymous ftp and only those you gave ip would try to login.
