AMD wasn't kidding when they said efficiency was way better, even if they defaulted to high power for the desktop models. What this tells me is that the laptop chips are going to be absolutely killer

@ismaelsoto9507 Жыл бұрын

Yeah, they just pushed their CPUs to the max to make it looks more impressive on marketing just like how Intel pushed the i9 12900K to make it be slightly better than the R9 5950X at the cost of double the power consumption. It's quite cool that we can make then super efficient if we want to.

@AmpEdition If you tweak the chip to run a reasonable temp that doesn't require a high-end liquid cooler then the performance loss puts in barely above last gen(plenty of videos that have undervolted with tests) . Add in the total cost of upgrading to this platform and this is a pointless release. Last gen barely loses performance and costs half as much. If this were Intel, I bet you'd be bashing them all day.

Yo phil, gonna piggyback on your comment. Another large problem that I think wasn't touch upon is that you can't possibly measure temperature at every spot of the die. It's just not viable, you can I guess run extensive tests on the silicon and have multiple temperature sensors per core and send back the hotspot only to avoid damaging the die. Well in the case with my 7200U laptop, it simply died from overheating at 100*C after 3 years of regular mixed use;

I took it further, always with a -90mV UV I locked the power to 95W and I still got an insane 16.9K on R23, at 65W it goes down to 14k and still touches 12k points at 45W.

@@vaggeliskosiatzis5487 I think the 12600k should boost at 150w stock but depending on the motherboard you can get different profiles, in my case if I remove the power limiter it will suck-up 180W and stay there (->18k). Fully stock the 12600k should score around 17k or something more, so in a sense I managed to squeeze another 700-1k points but reducing power consumption. With that said 145W + UV (->18k) still puts the CPU way out of the efficiency curve since with 95W it can perform roughly on par to stock (->17k). About binning I'm not sure if there is any difference between i5 and i7, but mobo and especially operating temps are important, I like a silent PC so even with the 145W profile I was targeting 85-90C which is not great for efficiency... It is probable that with the fans at 60-70% (instead of 20-25%) my temps would have been around 65C giving a bump in efficiency. And the last important variable is the silicon lottery

I would love to know more about 7900x since you’re already using it and know much about CAD and 3D rendering that are heavier than just game editing.

People are saying about 95C being the intended outcome of using Zen 4 chips, but with the current rising energy prices, having your energy consumption drop by about half is pretty significant, even if you have that baller money to get that latest and greatest, which is covered in the video, of course.

I think the temp thing is being blown up, I recently switch from a 1700x to a 5800x and while the temps reported are way higher on the 5800x than the 1700x the temps of the water in the loop actually increase way slower and reach a lower max temp under long heavy workloads

@Mike__B Жыл бұрын

People are saying that because AMD is stating that. It seems to be about 100 watts difference, which could be significant, it depends upon how often you hit max power on your rig, which honestly is not something I ever check for me so I really have no idea. But lets say you do 10 hours a day on average at max power, that's 1kWh difference per day (10hrs x 100watts), here's a situation that's probably well above the average person so now it's just a matter of multiplying by your electricity rate to find out the daily cost and 365 for the yearly cost, for me in California it's nearly 40c/kWh so that translates to just under $150/yeah which would be a pretty good chunk of change however how realistic is 10 hours a day on average? well everyone needs to answer that question for themselves, but if you go to 2hrs/day on average then $30/year (for me) which is less of a bother IMO.

@@JocaGod this is because the CPU doesn't run hot because it's using a lot of power, but actually because the CCD is very small and doesn't have the sufficient surface area to dissipate heat. I know a few people with the 5900X with no power limit and it actually runs cooler than a similar 5800X because each CCD only has 6 cores worth of heat it needs to dissipate. AM5 also has an extremely thick IHS the heat needs to get through, and derbauer's testing shows getting that out of the way gets you a 20 degree drop in temperatures.

Thank you for this quick guide, I dropped my 7900 to 0.985v and the temps dropped drastically. I have a hardware fan speed controller set to just audible, which is about 48% rated speed of the fans in my fractal Torrent, and the idle temps were high given the restriction. Dropped to around mid-40c now. Just updated to a 4070ti super, will look at an undervolt on that, but temps look great out of the box, if I can save power, that's a bonus.

This is actually absolutely real useful information, thanks! Not everyone lives in Sweden or Canada to enjoy the heat output of a 230W CPU consumed - and would gladly give up 5% performance / 100W of the consumption to have reasonable heat output of 130W consumed as this can also be cooled easily with all decent air-coolers. Also the reason why I undervolt GPUs, when your computer takes 600 W from the wall you already need an 1000w consuming AC to counter that and it's stupid; for 350W not so much. Besides it's nice to have lower temps, longer fan lifespan, lower noise, and avoiding liquid hazards, I mean, liquid cooling. I am aware not all CPUs are equal so then BIOSes cannot be set for Undervolting settings that would work stable on all CPUs, but this is like the default BIOS profile is for Overvolting. Haven't seen anyone test Eco Mode yet though, but I'm positive it does not compare to manual overclocking and undervolting that I usually do on CPUs and GPUs.

I think a better way is to use curve optimizer with negative all cores 15 (or more/per core if you want) + setting target PBO temp to 80 or 70 celsius. That way it stays low in idle and boosts high in single core but stays cooler in all cores workloads :)

@K41Z3RR Жыл бұрын

Like that, yes. I limited the temperature to 80 and set the negative curve to 20. That's 5.0 ghz tdp 150w with the Arctic LF ii 280 running at 80% power (180ppt, 140tdc, 200edc). While through the BIOS - Ryzen Master cannot start with the computer, it's annoying. A little disappointed - expected more frequency like 5.2 or smtn. I'm new to this, maybe something else will be improved later. upd: 20 is unstable, 10-15 is ok)) I don't know how some people put 30, they must be very lucky with their rocks.

It's such an issue how they handle temp now just because it ruins the entire fan curve paradigm we've been using forever. Unironically Ryzen needs the Turbo button back. Either to switch your PBO profile on the fly or swap between your nice friendly 1700 RPM fan curves to you ear-shattering 3200RPM fan curves.

@@thumbwarriordx I literally have a couple of fan control profiles in Gigbyte Control Center)) One for everyday work, when the fans run at 70-75% in case of limited CPU heating to 85 degrees, and the other - "no one is at home", when the fans run at 100 %. The two profiles provide different performance, although the difference is small. It's funny. And yes, it's pretty weird. But I can't say that it gives me any problems.

If anyone is struggeling with this, the best result I got with combining negative offset (in case of my 5800X -0.875V), with Curve Optimizer. I figured which offset was the first without frequency stretching and then generated a Curve via RyzenMaster, which was totally unstable, and THEN running CORE CYCLER for a couple time and adjust the Curve accordingly until it's fully stable. You can save time by starting with smaller intervals like 3 minutes per core and stability test for longer later. This got me lower thermals and more performance in single core as well as multicore, perfectly stable thanks to CoreCycler and is to my knowledge the best method right now for Ryzen 5000 and 7000 series. Took me 1 day this way, which is ok imo.

The Ryzen 9 7950X3D cache is rumoured to not be release until CES 2023 (Jan 5th-8th 2023). Having seen the HUGE boost in performance that the 3D cache gave to the 5800X3D, to the point where that last generation chip holds its own against the just released 7950X and the not yet released intel 13th gen flag ship, there is no way I would get a CPU before the 3D cache version, so I am praying the Ryzen 9 7950X3D is released sooner, just after intel 13th gen, so they crush it, and I don't have to wait even more months before building a brand new from scratch rig. Fingers crossed AMD have the sense to release the Ryzen 9 7950X3D straight after intel 13th gen so that AMD can corner the market before the Christmas purchasing rush!

DeBauer cooled it down 20 deg C by removing the IHS and cooling direct to the chip/chiplets. My guess is that you shaving 40 degrees already based on power consumption, removing the IHS would only shave another 10-12 degress. However, that would open up some interesting possibilities to bump your core reduction up to 4.9 or 5 while still maybe cooling it down to 50c. You should talk to him and maybe do a tuning collab.
