SSJ_naruto_2003 posted:Anyone have a good basic 12600k overclock guide? Haven't had to overclock in a decade since zen PBO was mostly solid. Is there even a noticeable benefit to overclocking anymore? I was under the impression that basically any cpu made in the last generation or so will throttle themselves up as much as possible until they hit power or thermal constraints. If anything, undervolting is better than overclocking now since you still get a slight performance boost but with reduced thermals.

BlankSystemDaemon posted:If consumer motherboard manufacturers built motherboards like server motherboard manefacturers, air could still flow through; see: every single 2U or 3U where memory, CPU and everything else just has a passive heatsink covered by a plastic baffle, and the fans are placed in front. Ideally most cases would be designed to have the airflow go from low to high but most are still designed to go front to back with component heat rising to be wicked away by the inefficient airflow. That's why I bit on an O11DXL and raised it an additional inch and a half using blocks meant to sound and vibration dampen a washing machine.

But airflow is not inefficient, it only takes a tiny bit of it to overcome natural convection

While true, I have mine up on a cheap end table to specifically prevent this. Then again, I'm the one who's for more horizontal Air 540-style cases.

This is a silly myth, and I'm surprised it still hasn't died. Convection is slow and weak, and even the slowest of fans overpower it trivially. Front to back airflow is no less efficient than bottom to top airflow. There have been experiments done with rotating cases while maintaining the same layout, and there's never any meaningful difference. Modern cases with multiple fans are pressurized systems where natural forces like convection no longer apply. Dr. Video Games 0031 fucked around with this message at 19:53 on Dec 31, 2021 |

I don't know, overclocking a CPU that peaks at 4.9 with a 150w limit out of the box stock for another maybe 300mhz doesn't sound like it's worth any amount of time or effort to me but .

GPU undervolting seems to be the new overclocking really. I've UVd my card for example and see no loss in gaming frames but the card runs cooler and quieter in games. In some cases people have found UVing increases performance with stock coolers too. In my opinion overclocking is a slowly dying trend as even lower end CPUs are so good these days although lower end GPUs are hindered by low VRAM capacity and those that have 10GB+ are pointless since the GPU itself is underpowered to efficiently utilise it and gain any benefits. Case in point the new 2060 release....

undervolting basically is overclocking in disguise anyway, it's just a bit more involved so it should if anything be a more interesting exercise

Tom's apparently bought a grey market 12400 and did an early review. Unsurprisingly it looks to be a gaming value monster assuming a) it drops around $200 as expected, b) b660/h670 boards are affordable and c) you can actually buy it. Still no video cards so I guess it's academic anyways.

How bad of a bottleneck will a 6700k be on a 3060 at 1080p60? Building out a system for my cousin, and would be nice to be able to repurpose this and save him a bunch of money. Forza Horizon 5 seems to be fairly well locked at 60 at auto-detected extreme preset, but that's not exactly the most demanding of tests. Need to find him a case now too...

Stock 6700K is pokey at this point, one running 4.7 GHz is alright at least in per-thread performance. I'd say that's a reasonably balanced budget system but again, there is going to be stuff that it just won't run well due to the core count.

Thanks, seems like this will probably work out fine for now and when it gets to the point where it doesn't any longer we can deal with it then. Good call on the OCing too, I'll get that sorted out.

I really don’t think most games actually stress more than 4 CPU cores at once - the vast majority of the benefit seen from moving up a product stack with higher core counts comes from the additional clock speed and cache on those same parts. A 6700k with a good OC would be very unlikely to be the reason for going under 60 fps at 1080p.

Begall posted:I really don’t think most games actually stress more than 4 CPU cores at once - the vast majority of the benefit seen from moving up a product stack with higher core counts comes from the additional clock speed and cache on those same parts. Modern games tend to be written to take advantage of at least four cores even if they aren't using every single one 100%, and while it's theoretically possible to make do with less than the game is created for by scheduler preemption and other time-sharing techniques, your performance is going to suffer for it. So if a game is written to execute the primary game logic running on one core, graphics on another, physics on a third and miscellaneous on the fourth core - that means there's not an enormous amount of resources left over for the overhead of the OS itself (and even if Windows 10 and beyond has features in DWM which minimize CPU usage for graphical elements when running full-screen or windowed full-screen), there's a bunch of other overhead that's simply unavoidable (think the lower parts of the networking stack even if some of it is offloaded, as well as whatever things you have running in the background, along with filesystem I/O and things of that nature). And if you're the type of person to leave a browser (or multiple, if you're running discord and a browser, because both are functionally browsers) running in the background while gaming, that's gonna get fun real soon. I know PC building and the word future-proofing are basically anathema, but it's hard to imagine a future where there'll be less or the same number of cores we have now, considering the trajectory ever since Dennard scaling failed in 2006.

It's true that a 6700k is getting beat pretty badly by modern CPUs. It's also true that some games have awful performance with <6 and sometimes even <8 cores. And synthetic environments where you're running nothing but one game on a clean install of windows aren't even real use conditions. I'm not saying a 6700k is garbage that you should throw in the trash, but it's definitely an outdated CPU at this point and a significant bottleneck. Is it a horrible misuse of a 3060? Not really, but you are leaving some performance on the table, and CPUs are very cheap compared to GPUs right now. For what he's doing which is a recycled budget build, it's fine. Just fine.

And no efficiency cores, so I'm going to assume that one can stay on Win10 / not have to worry about any scheduler fuckery going on. Will BIOS's let you just kill all E cores if you want 8 cores + don't want to upgrade to Win11/just generally don't want to trust something else on allocating cores efficiently? 12700F might be interesting then, but that's almost the cost of another 12400F to get 4 more P cores.

movax posted:And no efficiency cores, so I'm going to assume that one can stay on Win10 / not have to worry about any scheduler fuckery going on. Yes, you can disable E-cores. Right now this also allows you to enable AVX-512, but there are rumours Intel is going to kill that in the next IME update. If you have E-cores disabled you can also spin the ring up to (at least) 4.7GHz, some boards do this by default but not all. The Intel Labs Twitter showed a hwinfo64 shot of the 12900KS and it had 4.7GHz ring with the E-corres running, which is exciting. Right now E-cores active will cut the ring down to 3.6-4.0, which hurts memory and gaming performance. Also in the screenshot was 5.5 for 1/2 core, 5.2 all core and 4.0 ecore. Crazy chip, might even be a new stepping. I just read that Sapphire Rapids is renabling a form of TSX, can any of the lower level CPU guys in here explain how they've fixed it's Swiss cheese security?

From what I read online it seems most people have no problems getting their ring to 4.3 with e cores enabled at 1.35v atoml2 voltage, which also overvolts the cores. But it seems like more than that, let alone 4.7, is definite lottery stuff? Helped a buddy to set up his 12600k a couple weeks ago, and we got 5.0/4.0 P/E all core and 4.3 on the ring at 1.35v, but it used over 200 watts under cinebench. Dropping back to 4.8/3.8 P/E and 3.8 ring at 1.23v sustained resulted in 130w power draw. I suggested making that his 24/7 setup but he wanted the ~*sick gainz*~from the first overclock lol.

If the main downside of using AVX-512 is losing the efficiency cores, then there's no downside on the much cheaper non-K parts that don't have efficiency cores anyway, right? Seems like the 12400 is the real winner in all of this.

Seems like the 12400 is the real winner in all of this. The downside with those becomes the smaller L3 cache, which reduces gaming performance by a measurable amount. And there's no guarantee they'll ship the 12400 with any form of AVX-512 support if they're talking about patching it out of other CPUs. Intel wants AVX-512 to be an HEPC or server-only thing.
