gradenko_2000 posted:having lots of cores is nice because you can watch all the lines in top realtalk though, I bought a 3950x a couple years ago and it's loving amazing. i don't load it as much anymore these days and will probably upgrade to 5800x3d when 7800x3d kills its price, but it's still really really nice to be able to just ssh home and run something at 4.4ghz and 32 threads for work when I want to and wait a couple hours less because all the cheap 16core epycs at work top out at 2.4ghz

Klyith posted:It's stupid good for engineering simulation stuff. The reporting from back when those came out was that all the high-performance computing providers who sell time for that type of thing were all upgrading to v-cache epycs as fast as they could, because the speedup was big enough to pay for the hardware in relatively short order. one of my hpc friends already has genoa-x on backorder, says one of his biggest customers are some biology companies that are using machine simulation to simulate their poo poo and predict ~80% speed increase from it lol

yeah, wat hobbes said i play DSP a lot and stellaris with friends sometimes and i'm on a 3950x right now but i'm seriously considering sidegrading to 5800x3d because a) i no longer regularly require that much cpu power and b) stellaris performance difference between 5800x and 5800x3d is over 110% lmfao

Klyith posted:tl;dr if buying the x3d is stretching your budget, it's probably not worth it yeah, the only thing i'd add here is, if you're primarily a simulator/mapgames player, check some benches for x3d and decide if you want to skip a gpu upgrade and spend that money on an x3d instead because it's a minor boost in some but a complete goddamn gamechanger in others lmao

VostokProgram posted:Would going from a 5600X to a 5800X3D be a worthwhile upgrade? I play a lot of paradox games and Factorio and similar stuff i saw some german dude benchmark his lategame stellaris saves (just let the game run with zero input for 360 days several times on each cpu) when he upgraded from 5800x to 5800x3d and he saw a 117% game speed increase at fastest setting lmao stellaris is somewhat of an outlier because it's a 4x and a paradox game so late game gets really stupid, but even in "normal" games like factorio people see a 50% increase

ConanTheLibrarian posted:The 7800X3D is probably the most sensible option for gaming, but I'm genuinely interested to see if there's enough smarts in the drivers or OS to schedule games that benefit from either the extra cache or higher frequencies to the appropriate CCD on a 7950X3D. That way you get the best of both worlds. you can do this very easily. i don't remember what the command is on windows but you can launch apps locked to certain cores easily, there's even an option to disable hyperthreading specifically for an app and poo poo like that there's no way microsoft is going to maintain a list of games that run better on big cache or raw freq for you though, so you'll have to janitor your cores yourself

like i posted half a page ago, the "fix" is very simple but there's no way microsoft is going to maintain a list of apps that work well on certain kinds of cores, so unless you want to janitor that poo poo just get a 7800x3d best case scenario is probably some script or app on github that does it for you e: that factorio graph is insane tho lmfao

a lot (maybe most, even?) motherboards these days that lack a pc speaker instead beep through your on-board garbage ac97 chip, which is very funny because people definitely remember to plug their speakers in when building a pc, and also many new monitors totally don't ship with builtin speakers you're supposed to use through dp/hdmi it's all very stupid because one of those tiny pc speakers adds probably $.03 to the BOM? e: and the mobo mfgs will probably take the reasonable way out of this mess and start shipping bluetooth with their motherboards so you can hear the beeps on your anroid phone

i leave my pc on 24/7 because it's 2023 and idle chips sip barely any power, the difference between a full blown desktop at idle with the monitor off and a NAS is maybe a dozen watts plus, the fans all turn off, what with all the giant heatsinks designed to dissipate a gorillion watts, so unless it's doing something heavy or gaming, it's silent, too instead, my pc is the only "real" computer that's in the apartment and i skip all the NAS/htpc/whatever else other people run in addition to their pc, and run that poo poo on the pc instead. it's got more than enough power for the desktop experience to not get bogged down by whatever else is happening on the network, what with the 16 cores BlankSystemDaemon posted:A modern computer great post

honestly, with a desktop pc raw cpu freq can actually manifest in a visible change in games, with smoother framerates and whatnot, and those hardly load more than a couple threads so as long as you can keep that from throttling you're fine for most other workloads i don't really care if i'm hitting 4.8 or 4.4 ghz allcore. it's a 10% difference and i don't care if i'm waiting 30 or 33 minutes for <task> to finish. obviously for poo poo that takes days to finish 10% is again a big difference but then you're probably in threadripper or even server rack territory and those are completely different beasts anyway

sometimes i wonder if i should sell my 3950x and go for a cheaper and much faster in games 5800x3d now that i don't use all that cpu power regularly, but a couple times a year something really dumb happens that makes me glad i still have all the goddamn threads usually it's work related poo poo, but i'm playing stationeers with friends since a patch landed last week, and it's really nice to be able to run both the dedicated server and the game on my computer and still have the game perform normally i was worried because internet is littered with people complaining how vpses aren't beefy enough so as soon as you turn on ventilation in a big base everyone starts desyncing unless you go for a monstrously expensive one with many cores/ram, and how it's impossible to run the dedicated server and the game on the same machine and have a playable framerate, but i'm here just cruising along at 60-80% cpu usage and 90fps lmao thanks amd

it's not even limited to electron anymore, but it was lovely web apps that normalized that bullshit, and it's electron that moved it to the desktop app experience, and microsoft is now bravely following suit with actual native apps performing like absolute poo poo, seemingly without a loving care in the world that computers 3 billion times faster than those that existed in the 90s are slower for the end user it's even more jarring on macos or linuxes where immediacy is still present to some degree and then you install a discord/slack/etc and suddenly everything feels like you're computing through molasses but sure, electron apps are just fine because you have too much ram now i guess

you still have access too all the threads, though? you just can't run the cache sensitive threads on the low-cache cores, and since that post was talking about games, there's no game that needs both the cache and 16 threads to run well so far i mean poo poo, i'm still on a 3950x which has l3 cache only shared by 2 cores and it runs 8 thread games fine because even with going through the interconnect the cache is still tons faster than accessing ram

is it still better in gaming if you tell games that profit from the extra cache to only launch on x3d cores and games that profit from raw clock speed to run on faster non-x3d cores? actually interested if anyone did that kind of benchmark, though obviously budget wise it's probably never worth it
