mdxi posted:All six of my compute nodes (three 3900Xs; three 3950Xs) are now built on the Gigabyte B550M DSH3. It's cheap, and no-frills, but buildzoid called it out in his B550 preview vid for having an exceptionally good power delivery subsystem for its price. If that works for you, well, I guess, but the LTT VRM-rankings forums thread suggests quite a bit more, especially for the 3950.

Generally speaking, VRMs matter far less than forum people on the internet think, especially for stock operation. There are absolutely some total duds out there and if you are trying to squeeze the last 5mhz out of a part or doing LN2, oh yeah, VRM absolutely matters. But the marketing trying to sell $600 boards and epeen forum warriors have somehow convinced a whole lot of people that they need 12 phase VRMs with 90A SPS just to turn a 105w TDP part on without exploding, and its just not true.

We're still expecting Zen 3 TRs to be TRX40, right? No way they launch a new chipset just for that. Wonder if we will see new boards though -- still mildly irritated that I have to burn PCIe slots for 10Gb (Copper or fiber) on the PRIME TRX-40. If those crazy fuckers at ASRock put out a mATX board though with a fuckload of PCIe lanes broken out...

I installed a CPU cooler for the first time today! I'd been kind of scared of thermal paste and such it but it wasn't that bad. My 3300X now has an Arctic eEsports Duo on it a friend passed on when he upgraded to AIO which is a pretty significant overkill for the four core chip but I see surprisingly impressive performance improvements in CPU bound tasks.Cygni posted:Generally speaking, VRMs matter far less than forum people on the internet think, especially for stock operation. There are absolutely some total duds out there and if you are trying to squeeze the last 5mhz out of a part or doing LN2, oh yeah, VRM absolutely matters. Okay, maybe you'll be able to help me with a question I had on this topic? My motherboard (Asus B450 Prime M-A) is considered very poor - I bought it because a CPU/mobo/ram combo was the only way to get a 3300x and the price was right, and at the time I had no intention of overclocking at all. In particular apparently the VRMs lack heatsinks? Now that I've lucked into a better thermal solution I did some googling and found some people saying "the B450 is specced for much higher core count and TDP parts, overclocking a quad core on there should be fine" and some people saying that's untrue. I'm curious - would I be able to if I wanted to?

Until maybe you get to the top of the stack, no board is going to be unfit for operating within spec. The margins on these things are so small you don't want returns and there's not room in the market for the cheap crap at the bottom that floods every other thing-market. I can't imagine a board I wouldn't run a 3300 in, just don't have your case full of dead air. E: I should read the whole paragraph. Could you OC? Maybe. Odds are the worst case is the board doesn't live as long as it could. Id take a good considered look to see if that was the weak point before trying though. EE: I am by no means well versed in this, but internet people have a strong tendency to blow things wrt computer hardware / everything out of proportion.

It is a low tier VRM for sure, but thats not necessarily a bad thing. Having an overkill VRM doesn't really get you anything other than spending extra money that would be better spent on your GPU in games. Those value B450 boards were really designed for 65w parts with minimal airflow (including something like a 6 core Zen3 5600X, which the BIOS now supports). 95-105w parts like a 5800X or above will want some sort of cooling on the VRM to stay at load for any significant period of time without throttling, and that is exacerbated by the lack of heatsinks, but the situation at stock settings in a regular case with a couple of case fans is less dire than some think. I would probably target a 6 core 5600X as an upgrade, cause it will get you nearly all of the daily driver/gaming performance, and be completely within the boards capabilities without batting an eye. You can absolutely OC a 3300X on it, as well. It is not going to get to those crazy power numbers before hitting its frequency limit anyway.

Yeah, my upgrade path was going to be a 3600, 3600X or 5600X - ideally I'd wait until post pandemic and see stuff going secondhand so that's not for a long time yet. And even at stock speeds the 3300X isn't struggling with my 3070 at 1440p at all, I'm mostly just curious about the functionality given it's part of the package with AMD. I haven't had the option to even try it with my old Intel build - it's kind of novel. Thanks a ton for the responses!

Haven't had my morning coffee yet, but drat INTEL, YOU NASTY. Did I fever dream it, or didn't intel drop like ~20 CVE at the end of February already? If a cloud provider like, I dunno, AWS were to see a major security breach through any number of Intel security calamities, I wonder how much legal exposure they would have at this point. How could a vendor reasonably argue that shared tenancy on Intel processors is a secure situation for their customers after endless bullshit like this being found?

Yeah from what I gather that instruction only works when the chip is in "Red Unlocked" state, which is the Intel-internal god mode for debugging the processor If an attacker can coax your CPU into that mode it sounds like you're pretty owned even before they start tinkering with those newly discovered instructions repiv fucked around with this message at 17:10 on Mar 20, 2021 |

Really interesting chart that popped up in a GN vid (original source here): All of AMD's non-GoFlo business is not much more than Intel's spillover, and was less as recently as 2019. Nvidia was a bigger customer until this year too.

Upgraded from a 6700k Skylake i7 to a 5800x and wow this is so much better. Even when not getting big fps boosts in games I'm not getting drops and stutters anymore which is in some ways better than more fps.

Frametimes are absolutely way better than general FPS; games just feel awful to play without us being able to tell exactly why most of the time.

K8.0 posted:As GN Steve puts it, FPS is just an abstraction for the underlying metric of frame times. it's the same number expressed in two different ways, so it's not an abstraction of anything if you have a large variance in framerate, that is literally the same thing as a large variance in frametimes and equally bad don't make the mistake of taking techtubers as being too authoritative, they can get stuck into their own weird headspaces just like any random person, and steve's "frametimes are totally different from framerates!" is one of them. Or rather, he redefines it in his personal usage to mean something other than the strict technical meaning. when he says "frametimes" he usually uses it to mean "0.1% lows" or "framepacing", somewhat ambiguously.

There's a difference in how they're usually presented, FPS counters usually do a rolling average that obscures small variances but frametime numbers are usually graphed without any filtering There's no reason you couldn't show non-averaged FPS but people aren't used to it
