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. The one with the most performance is going to outsell the one that's most efficient every time. "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.

Think of it like this - people used to overclock back in the days to get massive gains in performance but now, company's have pushed the cpu to limit, there is nothing left to over clock BUT you can undervolt your CPU massively to gain efficiency instead of power. This way, people who care about efficiency win, and people who care about mad performance also win

@strat0caster124 Год назад

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 Год назад

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.

@guy_autordie Год назад

not itx gamer, and I will take a 7700X @65/105W all day.

@Wrenchingandnursing Год назад

@@guy_autordie I think that's a great option as well. If you are doing it for the noise and thermals that's great. With the price difference over a 13600k if it was done from a more energy saving standpoint you'd have to leave it on nearly 24/7 for a year or use it for a couple to negate the $100 difference.

@strat0caster124 Год назад

@@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.

@klobiforpresident2254 Год назад

@gamergod9182 Год назад

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 Год назад

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.

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.

Keep in mind the 65 watt mode is probably for mini atx systems where you can pair it with a small rtx a4000 or a4500 or similiar card so it would also make for a tiny workstation that could be tucked away in the corner of your mancave. You could use a itty bitty air cooler or 120 mil radiator and take up a fraction of the space a tower would and still run cool and quiet by adjusting the fan and power consumption of the small workstation cards.. I'd love to see some tiny workstation builds with this cpu

Yeah it's what we were all expecting to find, ya? The 7950X is waaay outside it's efficiency curve at stock settings. I imagine if you could hard limit the PPT to 170w, that'd be where the efficiency curve peaks and you get the best performance for the wattage. Good testing guys! Love this! :D

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!

@plaiseek1503 Год назад

If you want 125W TDP, which is 20 higher than 105, the diff between 105 and 170 being 65: PPT = 142 + (230-142) * 20/65 = ~169W TDC = 110 + (160-110) * 20/65 = ~125A EDC = 170 + (225-170) * 20/65 = ~187A

A small amount of under-volting is what you want. You can get the thermals and power draw down significantly, and the "overall" performance up (due to absent thermal throttling). It needs a PBO2 'tune'. Ideal power is close to stock, but just a bit down.

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.

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.

@Gamerss Nexus, please retest by 65 watt in ECO mode but under volt. This can sometimes take advantage of the 5NM technology and result in massive gains in games. This will not work well in all core but can sometimes boost a couple cores extremely high and hold the boost. Thanks
