Ryzen has been more power friendly than Intel Core for a while now. I don't think consumers care much about eco friendliness, though, which is a shame. I suppose it could always be sold as "doesn't heat up the room as much", but anyone with a dedicated GPU will have a computational space heater sitting next to them regardless these days.
- secondcoming 3y agoI think that yes they're more power friendly when doing work, but consume more power at idle than Intel CPUs. At least that used be the case, don't know if that's still the case. As for eco-friendliness... it's something I now consider when buying electronics but more from an electricity bill point of view.
- Dalewyn 3y agoIntel is very likely still the IdleM@ster[1][2]. Also, most CPUs spend most of their time idling or very low load, not belching hellfire upon the scorched earth. Efficiency at idle/low power is far more significant than efficiency at flame belching if power consumption over time is concerned.

- mihalycsaba 3y agoHow big is the difference on a regular setup? And is it a same kind of cpu, with integrated graphics? One of the example you linked says 7 watt, which is impressive, but I think you could achieve similar optimizations on an amd system. Let's say I install windows or some linux desktop and don't do any optimizations, how big is the difference?

- Retric 3y agoIdle power consumption is all over the place with AMD taking the lowest and highest spots on this chart: https://www.reddit.com/r/Amd/comments/10evt0z/ryzen_vs_intels_idle_power_consumption_whole/ https://www.reddit.com/r/Amd/comments/10evt0z/ryzen_vs_intel... Who wins depends on both the system and how it’s used.
- magicalhippo 3y agoI recall this blog post[1], discussed here[2] at the time, discussing how a SATA chip driver prevented the CPU from going to sleep state C6, instead keeping it at C3, leading to higher power consumption. Switching the SATA card to one with a different chip fixed that. There were other surprising factors which affected power draw. My takeaway was that as in real life, sleeping can be hard.

- Dalewyn 3y agoIn fact, you linked the exact thing I linked. :P
- magicalhippo 3y agoOh lol. Opened the links in new tab but didn't read before commenting, classic n00b fail. The "visited" look didn't phase me since I had, as mentioned, read it here before.
- wtallis 3y agoMost of AMD's desktop processors for the past several generations have had poor idle power because they're built using multiple chiplets with a cheap, power-hungry interconnect. The 8000G series (and earlier -G parts) are monolithic laptop processors re-packaged for the desktop socket, so they are unaffected by the main cause of poor idle power in AMD's main desktop processor product line.
- nl 3y ago> I don't think consumers care much about eco friendliness, though, which is a shame. Many do care about noise though!
- iamthepieman 3y agoFor mobile processors, it's one of the first things I look at though. And like you and others said I don't just look at the TDP but also rely on the big testing sites for load heat tests. Or, at least, I did until the m series processors came out and you could get a passively cooled laptop for a decent price.
- distances 3y agoMaybe not everyone but I definitely care. Lower consumption means smaller PSU and cooling requirements and less issues during heatwaves (no AC). Futhermore, my computer corner with a fair bit of electronics is served by only one electricity socket with a bunch of extensions cords that I really would rather not overload.
- Semaphor 3y agoYeah, my gaming (obviously I'm not playing AAA action games) PC runs on a 350W PSU and is rarely audible.
- smallstepforman 3y agoI do care about fan noise, my current system was specifically built for it (ryzen 3700x, rx5600 gpu)
- tiahura 3y agoWhy don’t more people put their pc in another room or floor? Even Amazon $20 HDMI cables are pretty resilient at 50’. Stuck my gaming PC in the basement decades ago and haven’t worried about cooling or noise since.
- twisteriffic 3y agoMost people don't have another room or floor to put it in?
- FirmwareBurner 3y agoWhy don't people just buy bigger houses with more rooms, d'uh? /s
- jijijijij 3y agoIn Europe electricity is expensive, though. If you pay 50c€ per kWh, energy efficiency does matter. Less heat also allows for a more compact or mobile design. Smaller builds are gaining popularity.

- DanielHB 3y agoTrue, I actually have been underclocking my RTX 3800 to keep heat and costs down.
- FirmwareBurner 3y ago>Smaller builds are gaining popularity. Gaining popularity in the ever shrinking market of PCs is nothing to brag about. I'd wager it's still not that popular as you make it be. Everyone just buys laptops nowadays and whoever they do buy PCs they get the full sized towers with discrete GPUs for gaming, not small form factors with APUs. That's more of a niche of a niche. That's why AMD hasn't focused too much on APUs for desktop PCs. It's not a big market. Their biggest sellers are APUs for notebooks and consoles, CPUs for datacenters and desktops, discrete GPUs for ... everything.
- Scrutiny6707 3y agoIt's been an "ever shrinking market" since the 2000s, if you believe the news. A thing to consider is, for the consumer market, machines have gotten good enough that most don't need a new machine for 5+ years, in terms of performance. Especially for casual household tasks.
- jijijijij 3y agoNo, you are right. I think this APU is basically a spin-off mobile processor. The technology comparison would be translatable, though, as with laptops battery life and weight matters. However, here we talk about the desktop market, don't we? And not every desktop PC has to be a gaming capable machine. Power-savings will probably be even more relevant for organizations running hundreds of office machines and terminals.
