Ryzen 8700G delivers comparable cpu performance to Core i5-14600K while using only one-third of the TDP

65 vs 181 watt

now that is impressive!

Be very careful about comparing TDPs, especially across manufacturers. It doesn't really say anything about real power consumption. The TDP difference is so big it probably represents some real difference in power consumption, but actual measurements are necessary to say anything concrete.

While you can't compare TDPs directly. Basically all tests of Ryzen processors with 3d cache use about half as much power or less than their Intel counterparts. So this wouldn't surprise me.

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.

In 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.

>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.

Re:Ryzen 8000G review: An integrated GPU that can beat a gra... by jijijijij on Tuesday January 30, 2024 @11:32AM (#39192103)
No, 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.

>And not every desktop PC has to be a gaming capable machine.

Yes, but desktop PCs not for gaming aren't really selling volumes nowadays, they're a tiny niche being eaten by notebooks and NUCs (also a niche) which Intel has been dominating as they had CPUs with iGPUs (basically APUs without the marketing) since ... forever.

>Power-savings will probably be even more relevant for organizations running hundreds of office machines and terminals.

When was the last time you saw organizations buy PCs for their workforce? In volume I mean, not just one PC for Bob who needed a CAD workstation, because then Bob most likely isn't getting an APU for CAD but some workstation with discrete CPU and some Quadro GPU.

Organizations mostly transitioned their office machines to notebooks a long time ago, even moreso after WFH became more popular so there was less need of PCs tied to a fixed location. PCs not for gaming or heavy compute workstations aren't big sellers anymore.

On what does it run on?

Yeah, I'm sure governments do buy some amount of desktop PCs because they don't intend for their workforce to work from anywhere else other than a specific office, but you also can't tell me with a straight face that selling PCs to the DMV, FBI and other bureaucrats represents a big lucrative market that was waiting for the APU revolution.

PCs are a low selling niche now. APUs won't move the needle on that, that's why AMD ignored it for so long. End of story.

It'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.

Maybe 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.

For 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.

I 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.

Intel 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.

I 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.

How 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?

Most 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.

TDP is arbitrary, they actually calculate it with arbitrary constants that change per chip. So it is meaningless at this point.

Also, chiplet based Ryzens are notorious for higher idle power consumption than Intel's monolithic dies, which is where CPUs spend most of their time in consumer applications (web browsing, netflix, shitposting on reddit, etc) instead of running at full load all the time.

Synthetic tests that stress everything at full bore, are not realistic representations for your average consumer PC application scenario. Even video games don't cause as much power draw as synthetic benchmarks can which are more akin to power viruses.

In real life daily driving, Ryzen might still be more efficient than Intels but with a much smaller margin than such tests might lead you to believe.

Is that idle? Not sure I could get this box at any lower use than this, even though I understand this is different from having all cores pegged at 100%.

We're talking idling from the perspective of an actual user at home, so there will obviously be a web browser and some background tasks running.

Idling without anything running, even an OS, is interesting for metrics, but not something realistic for any user.

I agree that we should be comparing real scenarios, but I also notice that my desktop Linux systems tend to idle at <=1% CPU use if I don't have a browser open, so there's probably some genuine room to consider what counts as idle even with an OS running.

Reporting the clock frequency of a core requires running a bit of code on it which necessarily means the core is in an active state while you take the reading, so you will always read something like "2.5 GHz" even if the core does not execute anywhere near 2.5 billion cycles while you do that. Some tools can report metrics like "average effective clock" which count time spent in inactive power states as zero clock.

Along with comparing what the others have said about comparing TDPs between vendors (or even different product lines sometimes) TDP is about multi-core draw so you'd need to also normalize the multithread performance differences between the two, not look at the single thread performance being near equal (that'll be significantly less than 65 Watts for each).

I think the 8700G is probably more efficient but it won't be anything like 65 vs 181 watt would leave one to believe.

Re:Ryzen 8000G review: An integrated GPU that can beat a gra... by zamadatix on Tuesday January 30, 2024 @02:44PM (#39194710)
Assumming:

- PL1/PL2 from Intel can be compared to TDP from AMD

- CPU Mark scores alone are the best indicator of what full utilization looks like vs another test

You'd be accurate. You can't really assume either of these things though. The better comparison to TDP from AMD is probably closer to "base power" of 125W than PL1/PL2 of 181 on the Intel side. Other benchmarks, like encoding using all cores efficiently with matrix extensions, are in the 25%-30% difference. Combine these two facts and it's probably closer to 1.5x efficient (instead of the 2.5x the raw numbers above suggest, 3x the relative improvement), but you'd have to actually measure active power doing the same amount of total work to know for sure. Even ignoring one of the facts the encoding benchmark differences are enough to guarantee it'd actually be less than twice as efficient, not at least twice as efficient.

The higher power consumption on the Intel side is mostly a reflection of the futility of feeding it more power. A better way to compare these would have been to dial back the power levels on the Intel CPU until it was only just as fast as the AMD part, and compare that power level.
Re:Ryzen 8000G review: An integrated GPU that can beat a gra... by ac29 on Tuesday January 30, 2024 @11:58AM (#39192483)
A better comparison of efficiency is task energy, which the article did cover.

In a video encoding task, the 8700G used 30% less energy than the 14600K, but it actually used more energy than a 13400.
