AMD Wraith - AMD's new box cooler to be shipped with Zen - Temperature tests

[ShintaiDK]

AMD's design philosophy is going to be to focus on the right engine for the right workload. So thats why they want to keep the Zen CPU FP at 128 bit. If somebody wants good FP performance AMD will have Zen APUs which crush Intel CPUs/SoCs for FP workloads.

As far as most productivity software and games are concerned integer performance is what matters and thats what sells CPUs in consumer market.

We heard that story before...multiple times.

We'd say that it fits in the $20 to $30 category, which represents some nice savings for anyone who's buying a new processor and doesn't already own a suitable CPU cooler.

Not bad at all, for those getting cpus bundled with this cooler, there's no need to buy aftermarket as you can overclock now with a stock cooler and sleep peacefully

Assuming that macho cooler isn't a piece of junk, it's arguably better than a $50 after market cooler.

That's even more impressive than I thought.

The Macho is a pretty good cooler. Like all towers, it requires some auxiliary case airflow to work since it isn't a top-down like a stock HSF. I would definitely put the Macho Rev. B above the 212 Evo

 

[mysticjbyrd]

Agreed. If the Wraith cooler can function as a stand-in for popular $30-and-less aftermarket HSFs then that reduces the cost-of-entry for AMD chips by a similar amount, especially for the budget overclocker.

If AMD sets up AM4 CPUs to be easy bclk overclockers, then major bonus.

What if AMD uses this cooler to sell Zen oc'd, sort of like the 9590k, but not as extreme. If I were them, I would do that.

Somewhat meaningless results if they don't disable APM. AMD CPUs power throttle under certain workloads, P95 being one of them. It shows that the Wraith and Macho are both capable of dealing with the maximum heat output of the configured TDP ceiling, but not necessarily that the coolers are equal beyond that.

(Wraith still seems to be a nice cooler and a nice value add for certain market segments.)

It's a possibility. We don't know what Zen's voltage scaling characteristics will be like. The cited 8c/16t configuration will probably pull some serious power as you increase voltage. That's just the way it is with moar coars.

Of "coars", power consumption will increase a lot - procentually. But one question remains: from which base power demands will it start?

Remember uncore power usage. It doesn't scale linear with core amount.

Unknown! Possibly 3-3.33 GHz base clock? I don't know what voltage will be required to maintain that clockspeed, which is where it would settle in during heavy loads (stress testing, where the HSF will get its real workout). That will depend a good deal on leakage and other factors.

Question: Does Scott Wasson still have an ownership stake the Tech Report?

Got to have that bling yo



7870ks and the UEFIs that support them are notorious for grotesque overvolting. The UEFIs have gotten a little better, but if the 7890k ever launches, it may have a stock vcore of 1.5v for its base clock, or something ridiculous like that.

As a 7870K owner, this is the reason. 1.425v out of the box as AMD must have laid off their binning crew or something. You can drop this down to 1.25v at stock speeds without issues (at least my sample).

 

[Madpacket]

The actual heat-sink is almost the same dimensions as the D3, only the FAN is larger.

The heatsink is clearly larger (percentage discussed in the video) to dissipate heat in addition to the better fan. That being said I don't think it would interfere with tall DIMMs as it appears to be designed very carefully to fit socket types that adhere to the standards.

 

[Madpacket]

Well colour me impressed. Now the whole argument from the Intel camp re FX series "well you need to buy an aftermarket cooler anyway so value = blah" will hopefully be put to rest.

Achieving 4.4-4.7Ghz is about what you can expect out of the newer binned FX chips with decent voltage so having a boxed heatsink capable of dealing with this heat (and blow top down which will help with surrounding VRM's etc) is pretty great.

Intel should follow suit with their K series processors.

You assume there is no issues. Under voltting is the same issue as overclocking. You have no way to guarantee a perfect outcome as the manufactor can.

 

[Madpacket]

Actually AMD should really sell this heatsink by itself for $20 USD and make it compatible with Intel processors and of course keep the glowing red AMD logo on it. I'm sure this cooler would be plenty for a 4790 or 6700K and still allow for decent overclocking. If they make it affordable enough you would have a bunch of Intel chip owners buying them up and providing free advertising for AMD

Like the TS15A cooler?

I'm assuming yes but I bet many other 7850/7870K owners would assume the the same (these chips are simply overvolted).

 

[DrMrLordX]

You can't make a statement like that taken in context, though. If you look a the p-states set for the 7870k and (presumably) the 7670k and then compare to the p-states for the older stepping chips (KV-A1) which had worse voltage/clockspeed scaling than GV-A1, you'll see that the board UEFIs are feeding more voltage to the newer, better GV-A1 chips at X clockspeed than the older board UEFIs fed to older KV-A1 chips at the same clockspeed.

Furthermore, the newer UEFI revs have (in some cases) jacked up the default voltage for older 7850k chips, which makes no sense.

Interesting cooler, too bad the price and availability seem limited. Also I don't see any mention of the TS15A mounting on AMD chips? Maybe I'm failing in my Googles.

I just bought two TS15As from Newegg.com. They are not hard to find and I paid $26/per so not exactly expensive either.
