Any power efficiency test for RyZen

[xkm1948]

Kinda interested in the power efficiency of ZEN. I wonder how good it is underload when compared to 5960X or 6900K.

My 1700X chip pulls 100W @ stock.

If the 95W chip only pulls 100 under load, how good is the 1700 65W chip going to be?
I'm considering changing my i5 3570K for one, to be used 24/7 for crunching.

THere are also dozens of reviews that go over this...

Guru3d got about a 90W-ish delta between idle and and load, so if you add another 10W for base idle load, seems like it's really pulling around 95~100W max.

Glad you asked

So, Ryzen is nicely positioned in the middle. Not to bad I'd say considering the amount of cores they all have...

Look again, it beats the 8/10 core Intel hands down, the 1700/x also beat the quad core Intel in every load test & sit just behind at idle. Looking at these numbers, it does look like an efficient little monster. Of course your mileage may very depending on the components used but atm the 1700 is the efficiency king, courtesy legitreviews.

But I'm the only one who measures power for CPU only; nearly everyone else does full system, which doesn't tell you how much the CPU is actually pulling.

 

[GoldenX]

I was just going to post that. Can't wait for 4 cores 65w APUs with Polaris IGPs.

If power efficiency is good looks like I may build my next lab server with RyZen, which will happen in about 2 months.

I assume RyZen can only accommodate 64GB RAM for now, right? @cadaveca

I see the value in such a measurement, for some, but for most (readers here...) system power is enough as most only want system draw. I mean it's all being powered from one psu. Tdp is plenty to give one an idea (stock).. which all reviews do all day what most people want.

The difference is hardly worth considering...to me.

Or you could wait for the Enterprise chip "Naples" to drop and build a monster system.

IMO lack of sufficient power (wattage) is why all Ryzen chips suck at OCing and boosting. I mean look at even their 1500X quad. Instead of being clocked higher than their 8 cores, it's only 3.5-3.7.

I was very skeptical when they mentioned laptop level wattages. It was a bad move IMO. Intel is going to exploit that with their next line of chips, like they have all bad decisions by AMD.

Don't get me wrong, I really wanted AMD to succeed for healthy competition sake if nothing else, but this is really a false victory for them. Soon people will see it for what it is, smoke and mirrors.

Intel doesn't want or can't have AMD prices, that's enought for any country (like mine) where performance is secondary to price.
I see more FX4000/6000 than i3s or i5s here, for example. Not to mention AM1s.

I would say that the process is problematic here and needs more maturing to reach higher clocks. The yields might be good, but the clocks are not there yet. Also, the unusual clock distribution can be explained by binning -> 1800X are the chips with best clocks, the rest gets put in lower tiers or gets cut down. Currently even quad cores are cut down from the eight core chips, but I'm really not sure what is difference in regards to chips designed as native quad core.

That is mostly true in their extreme line of chips, which are used as much if not more in the business sector. You can't really say that of their quads, because they perform WAY better than AMDs chips.

This is just for our lab PC. If my institution has plan to upgrade cluster in the future I would suggest Naples then.

Most likely they are going to say no. Since the computing cluster my University currently have is Haswell-EP. They may upgrade to Broadwell-EP in the future much easier.

Far from it, their cost structure, operating expenses & FAB's are expensive, more so than AMD. Not to forget that the quads do have IGP, the upcoming mainstream hexacore will also have an IGP, so they really can't sell cheap quads/hex without gutting much of the HEDT lineup. Then again HEDT was an artificial segmentation, so maybe Intel needs to get down back to planet earth if they don't want AMD to dominate the desktop/notebook segment in the future, remember the Vega based APU could be so much better than their counterparts.

Nice thread... need this bc I need power efff. as I got wonky power here even on a sunny day my power goes out for a few mins and I might happen to be in the middle of upgrading beta hardware's firmware... and that is suuuuper stressful to return/replace it.. I have to have UPS units on all my systems as well as my network infrastructure....I want good runtime . I also run servers and VMs and such... so I need max runtime but high performance as I can get per watt... this is why I've leaned Intel lately, I hope AMD will prove themselves with this...

You working a review here for TPU?

I do board reviews, so yes, but maybe this is not exactly the type of review you were hoping for. W1zzard is working on the CPU review, which is probably what you are looking for. That's why I have CPU-only power draw numbers; I am looking at board VRM efficiency as well. Testing like this is the only way I see to provide an accurate picture in board differences in this area.

 

[OneCool]

Well giving the issues with AMDs new baby. Motherboard and memory is going to be a huge part of just how well W1z review of AMDs new architecture will go. I'm sure you guys are communicating a lot to give us a real sense of what's going on here.

If you're implying the Ryzen quad will easily compete with Intel's current offerings, I thought so at first too, until I saw the overall poor OCing and boosting of the so far released Ryzen chips. Plus the 1500X quad will only be clocked at 3.5-3.7, and it's way lower wattage then what they've released so far.

Now granted, I'm sure the 1500X will be significantly cheaper, but it will likely have to be for performance reasons. I really don't think Intel need to panic over anything Ryzen.

As for Intel insisting on putting IGP on chips that are largely sold for gaming, that's just a poor marketing choice IMO. I would say AMD makes far worse decisions though. IGP makes sense on mediocre level CPUs that are targeted for low budget OEM PCs, but it has no place in high end chips used for gaming.

No, I'm saying AMD has an edge because they aren't selling quads/dual cores with an IGP. In that sense Intel shot themselves in the foot through artificial market segmentation, it's also hard to justify a new socket/motherboard every two years. Basically with Ryzen, looking at most of the benches & having some clue about Vega (IGP) performance in APU mode, being priced at the lower end of expectations, I fully expect AMD to smash Intel product offerings across the board in terms of VFM. I'd be surprised if AMD doesn't take away a big chunk of Intel's market share, on desktops & possibly even more with notebooks.
