Nick Esasky posted:so, question about how this AMD Starfield promo works: I just got a shiny new PC built for me with a 7700 CPU + a 6750 XT GPU in it, so i'm theoretically eligible to get both the Standard + Premium edition . I have two coupon codes on my recipe, but i have no idea WTH either of them correspond to. If i toss them at AMD's coupon site, will it just check my PC and give me the Premium since i have the video card installed?

Hi everyone, I'm living in an apartment with terrible power, and I'd like to reduce my wattage during heavy gaming. I've heard about a voltatge "offset" and I went poking around, but I don't know where these setting might be or what they're called. I've got an MSI B550 tomahawk with a 5800X3D. I'm not looking to push the envelope, but would like to know what a safe-and-sane reduction might be... and where I might find it. Thanks!

AARP LARPer posted:Hi everyone, In the overclocking section, set CPU Core Voltage to Offset Mode. Then set offset mode mark to - (so negative offset) and your offset to a number. Sane numbers are 0.15 (any CPU should be stable with this) to 0.30 (you need to be somewhat lucky). However, this will not really change power use. The CPU will use about the same power, and the lower voltage may allow it to hit higher clockspeed. If you actually want to reduce power you should use PBO Eco Mode. This is the best way to limit power while still getting pretty good performance. That's in Overclocking -> Advanced CPU Configuration -> AMD Overclocking -> Precision Boost Overdrive. You should have 3 choices for Eco Mode in that selection menu, 95W 65W and 45W. The 45W will have some real performance impact, but you should try both 95 and 65 in a couple games and see how they go. Depending on which games you like and what your GPU is, you might not notice the difference. Also generally a GPU is consuming way more power than the CPU in an average gaming PC.

So I see that AMD hasn't released a newer version of their 3D V-Cache scheduler thingy. Do they think it works awesomely now, or are they just waiting on Microsoft for a generic implementation, similar to the power stuff back with Zen/Zen+?

I'm assuming there is no better version planned. This is just how the 7950X3D will be, and if you want something better then you will need to wait for the Zen 5 version. They're trying to bolt a heterogeneous design onto an architecture that was not designed for it, and the hardware scheduler just doesn't have the features to make it work well. That's why AMD is relying on software to detect games and use the brute-force process affinity approach. If they want to do something smarter, they'll need something like the Thread Director intel developed for their big little chips.

AMD is supposedly going to have big/little chips pretty soon, rumored to be next year on mobile with Strix Point (a mix of 4 Zen5 and 8 Zen5c cores). Hope they are already working on some sort of solution that doesn't rely on the OS scheduler.

It’s still the OS scheduler, thread director is “hints” on what to run. The kernel’s role is still to execute threads on specific cores.

Right, Intel still relies heavily on kernel-level scheduling, but I doubt it would perform anywhere near as well without the thread director. AMD lacks anything like that, and it's not something they can just patch in either.

Yeah, ASRock's new bios allows for really high memory speeds, but it may not help performance much in most things because the uclock goes into 2:1 mode with the memclock. As seen in that screenshot, 4000 memclock with 2000 uclock, while on a DDR5-6000 EXPO kit, you'll get 3000 memclock and uclock.

AMD have repeatedly stated that DDR5 at 6000MT/s is the sweetspot for Ryzen 7000-series CPUs, and everything we've seen so far seems to bear this out. If we can get 4x 48GB UDIMM DIMM-wide-ECC DDR5 at 6000MT/s at some point between now and when the Zen 5 X3D chips have come out and dropped in price, I'll be ecstatic.

I've got an ASUS board that, at launch, wasn't able to consistently POST above 4800, even with kits that were rated by both ASUS and AMD as being valid at 6000. I'm hoping that nine months and several BIOS updates later it'll be able to do so as advertised. Dozens of claims on reddit of this have been posted and it's just beyond hosed. ASUS really hosed the dog on this board, but hopefully after almost a year of incremental improvements maybe it'll do what they said it would when it came on the market.

An AMD employee spoke about it here. The main change is the new "DDR5 Nitro Mode" (very AMD name), which is the frequency-at-all-costs 2:1 mode. I fiddled around with it on my X670E Hero, and it's not just a binary setting, there is a whole page of settings that you can tweak. The descriptions mention latency costs for Nitro mode settings even beyond the cost of dropping the UCLK, so it remains to see how viable it is for gaming. Plus the training times as soon as you enable nitro mode are absurd, like 5 minutes to train 7200 on my board. The other part that the employee mentions is tweaks to enable 6400 in 1:1 on more CPUs, and sure enough, I can now run 6400C28 1:1 with my 2x32GB M-Die kit. Was impossible to stabilise above 6200 on 1.0.0.7A Patch A.

Cygni posted:Underneath the marketing speak in that interview, they still have some of the exact same problems for mobile/desktop as Alder/Rocket (and Lakefield before it) had. Regardless of ISAs or theoretical max IPC of the cores themselves, they will have fast power hungry cores with lots of cache, moderate efficiently clocked cores with less cache, and slow SMT threads on the big cores... all of which have dynamic performance based on power and heat targets, and will be working with OSes that are making decisions of what to put where based on high level and slow to implement assumptions. It might be simpler for AMD to address than on ARM or Intel, but they still have to address the issue to maximize the design. Relying on the OS scheduler making adjustments in the 10-100s of millisecond range without knowledge of the underlying architecture efficiency tables isn't gonna be ideal. I didn't see that as marketing speak, but rather intentional ambiguity because he wants to basically walk back some of what Papermaster said, without outright just saying that or making it look like what Papermaster said has been wrong. My personal interpretation of that interview is that he indicated that AMD still has relatively little interest in going to LITTLE.big/etc., and instead would rather optimize the cores for their specific uses, i.e. Zen 4c/5c could be ideal for power-efficient laptops, servers, etc., while standard Zen 4/5 could go into gaming laptops, desktops, etc., where power efficiency is less of a concern. So it isn't the Alder/Rocket Lake problem at all. And to me it makes sense, because unless you're applying it to a closed hardware system like a mobile device or Apple's closed ecosystem where you can really optimize for heterogeneous cores, then you'll end up like the Alder Lake/etc. circumstances. Intel could have just thrown more efficiency cores in lieu of performance cores and called it a day, and Alder Lake would probably have been even better? Edit: Ironically if the performance ends up being accurate to what we saw, then Zen 4c could be AMD's "Pentium M-> Core" moment of sorts.

What is an OK temp for a 5600X3D if I run something like Prime95 for 5-10 minutes? Just want to see if the cooler I have is sufficient, or if I need a better one. I would be using the temps reported in HWMonitor to verify.

For the more memory focused tests or something like cinebench what temperature are you seeing and what frequency? 4.35GHz all core stable should be possible but would by no means be necessary to get good gaming performance because that’ll be mainly be heavily loading just a couple cores. hobbesmaster fucked around with this message at 18:09 on Jul 21, 2023 |

My 5800X3D sees 4.42 all core stable at ~70C under "real" all-core workloads and still hits 90C with prime95 small FFT. That test is just brutal on these things.

people generally need to suck it up and dwi, 7000 series is getting cheap enough it's pretty much just better now. Getting 7600X or whatever is really fine too. Especially now that 4x32GB+ appears to be getting stable at reasonable clocks on gear 2. that's fine, especially with the 7800X3D. with some of those skus being APU cutdowns probably, people should carefully consider the implications of the particular SKU they're buying in terms of pcie lanes (some may be x8) and cache configurations, reduced cache on APUs will hurt games somewhat. I, again, think 7600X bundle (often less than 7600) and 7800X3D are the ones that make sense for most people. 7800X3D is a value winner that helps drop your VRM power while boosting performance, get that Asrock Lite whatever. I used to still think AM4 would be better for UDIMM server builds because of 4x32 easy compatibility and I think AM5 is probably good enough to not matter now, (for gamers) especially with the ram bundle deals. otoh, zen5 is going to be a big deal when it comes out in probably end of next year or w/e. legit big improvement, zen4 was conservative to port onto DDR5 and zen5 is the big rewrite. it should be fairly significantly better, although I think they're taking the same big/little dive a little bit and gaming enthusiasts still want 8C X3D all-p-core type skus.

The 7800X3D is not really a good value when the 7700X is almost as good in most games and better in non-gaming tasks while costing $100 less. If you're blessed with a Micro Center, you can get a 7700X, a decent motherboard, and 32GB of RAM for the same price as the 7800X3D on its own. That's an impossible to beat value, to be honest. The 7800X3D basically only makes sense for top-of-the-line builds or people obsessed with sims. The 7500F is not an APU, and it doesn't have any less cache per core than the rest of the Zen 4 non-3D lineup. It's a 7600X with no iGPU, 1GHz lower base clock, and 300 MHz lower boost clock. Base clock is largely irrelevant these days, so it will only be marginally slower than the 7600X in practice. It could be a solid mainstream choice if the pricing is good, though right now it'll only be $20 less than the 7600X, making it a bit more questionable.

I don't think the CPU prices themselves have ever been the problem with AM5 adoption. DDR5 is in a much better spot than it was around the 7000 series launch but motherboards still look about the same. 235-250 eur for a barebones PCIE 4.0 itx board feels rough.

You can't divorce the CPU prices from the motherboard prices. Since AM5 is a new platform, when you're buying one, you're buying the other. A discount on CPUs is as good as a discount on motherboards, and these lower CPU prices makes the AM5 platform much more affordable. But also, there have been some modest discounts on motherboards too, as well as some fairly good bundle prices on Newegg (and some killer bundle prices at Micro Center—see above). For shoppers on a budget, there are even some acceptable B650 motherboards in the $110 - $150 range now too.

Up here in the great white north, a 7700X is $370 CAD and a 7800X3D is $590 CAD. It is over two hundred dollars cheaper to buy the 7700X and maybe lose an error bar's worth of frametimes.
