AMD Ryzen 7000 CPUs on Zen 4, including the R7 7700X, R5 7600X, R9 7900X, and Ryzen 9 7950X, have an optional "Eco Mode" feature in BIOS that can be enabled for power savings. There will be a cost to performance, naturally, but the goal is to minimize the negative trade-off and maximize the power savings (and reduction of heat). In this video, we're benchmarking the preset Eco Mode options (65W vs. 105W vs. Stock/170W) on an AMD Ryzen 9 7950X CPU. The tests mostly focus on a focused list of parts -- namely, the new Ryzen parts -- with a few showings vs. Intel's i9-13900K CPU.

@@strehicabih5246 You can find the PBO values for any TDP with a simple interpolation on the values provided by AMD for 65, 105 and 170W. Following this, I set my 7950X to 125W TDP with the PBO settings : PPT=169W, TDC=125A, EDC=187A , this gives acceptable thermals (80°C max with high end air cooling) and performances even closer to the stock ones. Adding a slight undervolt using the Curve Optimizer setting, performances are even better than stock, with a 30% energy saving! If targeting 125W TDP, 105 being 20 less than 125 and 65 less than 170: PPT = 142 + (230-142) * 20/65 = ~169W TDC = 110 + (160-110) * 20/65 = ~125A EDC = 170 + (225-170) * 20/65 = ~187A

If you have 2 CPUs for the same price. One is less performance but more efficient, and one is less efficient but has more performance.

"Efficiency" is almost exclusively an argument that a fanboy uses to defend their favorite brand when it falls short on performance. X is more efficient than Y, so X is a better per watt value. Meanwhile the rest of us are popping the IHS's off our CPUs and using liquid metal to run more power through them.

I understand that GN is usually looking at hardware from a more traditional sense, hence constantly reminding that "300MHz all core". But the reason why many people look at these ECO modes is that the thermals and system noise concerns overcome the significance of the performance. For me, it's not that you "lose 300MHz all core and that's a lot", but rather you "lose 6% of the core clock while reducing 50% power consumption". That's a truly impressive and disproportionate improvement. Personally, I care about these things because I am an ITX gamer nowadays, and there is a limited thermal budget for the system and a limited noise budget for my own sanity. My logic in looking at this is "what's the best performer at certain wattage that my cooling system can handle", and from that point, even a 20-30% weaker than stock 7950X is still within consideration. Although realistically, the best performance-to-cost ratio probably lies somewhere around a TDP limited 7700X or a 13700K for gaming.

@Wrenchingandnursing Жыл бұрын

From a gaming standpoint, what's your reasoning for the 13700k over the 13600k? IMO the performance gain is negligible to the price difference, and the 13600k outperforms everything in the field in a gaming sense except the other 13 series, and they don't lead by an incredible amount either. I almost don't even understand why the 7's exist anymore, with the 13600k being 14 core 20 thread, and having impressive workbench capability anyways. Seems like if you really needed something more from a workbench standpoint, you would just get a 13900k or 7950x as nothing else really justifies the price to performance difference.

@strat0caster124 Жыл бұрын

@@Wrenchingandnursing I just took 13700k as an example of something "not the flagship". I'm not that familiar with the 13th gen lineup, and the i5 may as well be more sensible than the i7 for gaming purposes with a limited power budget. I just vaguely remember that people were picking the 12700k as the sweet spot amongst the 12th gen lineup. I think the mid-range SKUs still have unique spots in this performance vs package power chart. Say we set a 65W power envelope, for the 7600X to the 7950X the average W/core decreases respectively. I think the peak performance per W probably lies somewhere around 6-9W/core like the 105W 7950X, so for a 65W limit the 7700X might make the most practical sense, in that you don't lose 30% of performance like you do for a 65W 7950X, but still has the thermals under control. But that's a very rough guess and might as well be wrong since CPUs work in very complicated ways, and we've seen that the games don't scale very well with these Ryzen core counts, so maybe a 45W envelope 7600X is all you need for the best overall price-gaming performance-noise experience for going AMD. Again I don't know too much about the Intel chips, but they seem to draw not that much power in gaming compared to some other workloads. My guess is that given a certain power limit, the 13700K might still be better than the 13600K, but maybe not by a huge amount, so the 13600K might as well be the most reasonable choice.

if you'd just adjust the PBO curve offset or PPT limits manually rather than using the Eco preset, I'm sure you can get results within 1-2% of the top results while still reducing power and thermals massively. also, remember that it's not always just about the cost of energy. being able to half the output of your 700 Watt "room heater" is a blessing during hot summers.

@vgamesx1 Жыл бұрын

Probably, similar thing for older 3000 and 5000 series, where manually adjusting the limits can get you pretty close to stock performance while also getting most of the savings of eco-mode. Also don't forget about noise, not everyone has the nicest cooler and although they're much better these days the stock coolers are a bit noisy when they ramp up more than about 30-40%, so being able to maintain that more often is also a big benefit.

If you have a 7950X, you could try to enter the following manually into PBO: 186W, 125A, 197A -> This is exactly in-between AM5 105W cTDP and AM5 170W cTDP mode according to the table at 5:55. I bet you only see slightly lower performance in benchmarks only but won't be noticing ANY difference between Stock and this setting. Also, it will probably still lower temperatures down by 20 Kelvin, which might even result in higher clocks (and thus even higher performance) depending how constrained your cooling solution is!

Just upgraded to 7700X yesterday and met with absolutely fans blasting with first benchmark because of 90+ temps. But I knew that before buying. After enabling ECO mode, which for 7700X would be 65W as it is 105W TDP stock. Huge difference in temps(Barely hear fans as temps stay around 60) and decent power consumption. And while it is not same CPU, I dont expect huge drop in performance with 7700X either.....eco mode is the way to go. I somewhat understand the need to extract everything out of the CPU while sacrificing power and thermals...because performance sells. At the same time, they almost lost my sale if it wasn't for the eco mode, I just wish they mentioned it more. Although it was kinda simple option in the bios if you search it and I believe Ryzen master has it also. I didn't actually know that. After reading couple articles I though you had to input numbers in the BIOS/PBO and thats what I first did. Didn't actually work for some reason, but then I found simple eco mode setting in bios and that worked well.

Ecomode could be well worth it in select circumstances, as power cost approach the cost of the cpu itself. With 170W saved in 65W ECO, with 24/7 operation and power costs at 0,4€ (not unseen in Europe right now) the CPU would gulp 595€ in just a year. At the end a 100% utilization is unlikely though and opportunity costs can be significant. 105W ECO could be a good tradeoff for highly efficient computing and lower running costs.

Most games barely touch the CPU anyway, so it won't matter if they're not getting full juice.

@Defective Degenerate where did you see performance lost for 105w

@alistairblaire6001 Жыл бұрын

Would be great to have a physical button on a PC case that instantly would switch between stock and 105W Eco. Maybe label it “Turbo”…

Boomer spotted! Meanwhile I grew up thinking it made things faster, like turbo buttons on game controllers.

What a novel idea! Just for shit and giggles when it's on make it use the eco mode, too.

I wrote an AutoHotkey script to switch Windows performance profiles for essentially this effect!

Having the option is great instead of locking it down to 105 only and keeping the default at ultra-max is fine for the most part. Love the sleep deprived still going hard effort, thanks Steve!

16:50 That usecase is well into Threadripper territory anyway, very excited for Zen 4 Threadripper and whatever Intels next HEDT platform is BTW

I actually really think eco mode has a place in the laptop market. Imagine being able to plug in your laptop and get the full 170-watt performance, but when on battery it consumes 65 watts. Accompany this with the ability to swap between integrated graphics and a dedicated GPU. You could have a laptop that can GAME hard when plugged in but have a really good battery life.

Don't laptops already do that?

@ShawFujikawa Жыл бұрын

Laptops have done this since forever, albeit not as much for battery life and thermals as much as laptop batteries aren’t powerful enough to drive desktop CPUs running at full tilt.

@mrm7058 Жыл бұрын

65W is quite a lot for battery. 15W to 25W would be better in this case.

No proper laptop has the cooling for a 170W CPU.

170w on laptop? LOL

I've been waiting for Gamer's Nexus to cover this. I'm one of those people who want to game without consuming an expensive amount of power. For those reasons, I don't usually buy Intel or Nvidia if AMD is being much more power efficient with their products.
