300W suggests they haven't got a hyper efficient new architecture and are just throwing more power at the problem which isn't going to work.

 

[Despoiler]

300W suggests they haven't got a hyper efficient new architecture and are just throwing more power at the problem which isn't going to work.

It doesn't suggest anything. There is no way to know what they've done between the last generation and this new card without the new card being available to analyze.

 

[Rvenger]

It appears they may be shooting to double performance over Maxwell. This may be Bermuda though which should be watercooled. Fiji will probably aim for efficiency.

I can't see this being the 380x. I think WCCFtech has it wrong here.

 

[Noctifer616]

300W suggests they haven't got a hyper efficient new architecture and are just throwing more power at the problem which isn't going to work.

In order to know the performance/watt ratio you need two numbers, power usage and performance. You got one of two and that somehow that tells you how efficient the architecture is?

 

[geoxile]

It's probably the 28nm GPU that taped out way back last year.

 

[Creig]

They do need a major re-design, there performance/watt is just killing them. It forced them out the mobile market years ago (as mobile kepler was still significantly better then anything AMD has), and now it's forcing them out of the desktop market - the one least effected by power requirements.

What exactly is the "power requirement" discrete GPU market? HTPC? That's the only one I can think of and there aren't many of those out there. Most people who are considering purchasing a discrete GPU look chiefly at two things: Price and performance. Power consumption isn't even close. And AMD is the current leader in priceerformance video cards.

They can't get ahead by using a better process node as nvidia will be able to use exactly the same one. The real question is can their hardware team manage it after all the cutbacks? The answer is unlikely - nvidia has more R+D, better focus, and is probably years ahead of AMD in design and is still pushing hard.

The 290/290X still hold up well against the 970/980 despite being an entire year older. Even more so at higher resolutions. AMD convinced VESA of the importance of including Adaptive-Sync in the DisplayPort standard and have unveiled multiple FreeSync capable monitors at CES. AMD's next flagship video card is rumored to have HBM memory which will dramatically increase bandwidth.

So yes, Nvidia is working hard on future designs. But then again, so is AMD.

+1 Same here.

The more power/heat you produce, the more you have to cool. That means bigger, more expensively-built laptops. OEMs prefer smaller, cheaper cooling designs. Efficiency is important.

Also realize that OEMs often will cozy-up to one supplier for a majority of their design wins. That means a company like Dell/Alienware or Asus will use NV or AMD as their 'main' options for their smaller to full desktop-replacement models. On the bigger laptops, a more efficient design also allows for a SLI configuration on really high-end discrete setups.

Efficiency is REALLY important...

 

[Borealis7]

yes it is, but 380X and "laptops" should not be in the same paragraph.
the parts that do eventually go into laptops will be no where near 300W.

you got your power envelope on one hand, and architecture efficiency on the other, you smash them together and hope for the best.
a more efficient arch will allow for better performance within the envelope on the top tier, and a lower power consumption with relatively good performance on the lower tiers.

 

[Mondozei]

I'm laughing at all those who take the 300W very literally. By the way, did you miss the SoC designation? SoCs are more than GPUs.

And then there's the whole engineering thing called 'samples'. Oh man

 

[RussianSensation]

I am sure if AMD goes water-cooling and 300W, they are gunning for a huge performance increase not the laughable 10% NV tried to pass off as 'flagship' with a 980 over 780Ti. If this card can beat GM200 and beat 980 by 35-40%, as long as it runs cool and quiet with hybrid WC, enthusiasts will be interested. Let's not forget that TDP does not necessarily align with average or even maximum real world power usage. As far as laptops are concerned, there is no way either AMD or NV are putting flagship speced 390X/GM200 into those. AMD likely has 2 separate engineering teams designing Bermuda vs. Fuji.

I am perfectly A-OK with a monster performing 300W GPU. What's NOT ok is if 390X is only 20% faster than a 290X but uses 300W.

But gotta give credit to NV as Maxwell is an excellent perf/watt product which makes me think GM200 will also be a fast product.

I've always wanted NV and AMD to make 300W desktop cards as long as the performance is there! Then again it's hard to take any leak seriously from wccftech.

 

[NTMBK]

300W? Please let that be a typo. I thought HBM was meant to drop power consumption, not completely blow it up.

 

[RussianSensation]

AT pointed out that 290X had an unofficial 300W. That makes it plausible for 390X to have an unofficial 300W TDP as well. The linked in profile also indicates the class type that 390X would be -- high end. It might not mean that it will actually use 300W in games.
http://www.anandtech.com/show/7457/the-radeon-r9-290x-review

IF by some chance AMD did decide to go 28mm 550mm2 300W + Hybrid WC for the desktop, they probably weighed in the pros and cons of releasing such a power hungry card after the poor PR associated with 7970/290X. Perhaps, if true, this does signify that they are taking a huge risk and going for the single GPU performance crown, something they haven't done since X1950XTX.

This.

Probably see 60-80% of this for really intensive games, and closer to 100% of TDP for more compute-type applications.

This means the card would probably have to have 2x8pin PCIe connections, if the user was to overclock at all. Otherwise bus (75w) + 6pin (75w) + 8pin (150w) would be JUST enough.

2x8pin (300w) + bus (75w) would give ~20% more power for overclocking.

that said, that's a lot of power for a single-GPU card! But also a lot of brute force

 

[DiogoDX]

So one resume talks 300W HBM and other metion 380X. This still could be 2 different GPUs (390X and 380X)?

 

[Rvenger]

I guess AMD could be naming Bermuda the 380x and Fiji might end up being the 380 or 370x? They may have another card up their sleeves to counter Big Maxwell so they are releasing the 380x as Bermuda with maybe some locked shaders.

I'd have to say that AMD has done an exceptional job keeping the leaks under control. Normally at this his time we know exactly what it will be and about how much it will cost.

Maybe the new 370, 380x all designate the power usage as well as the SKU?

:biggrin:

I'd be happy if they at least publically state the TDP.


EDIT: You know what. I have been thinking of this and this is just speculation at this point. The reason AMD is possibly going with a 300w TDP is because they want to market the card as a 4k gaming single GPU. They are probably trying to squeeze every last drop of performance within the 300w TDP.

Anybody can be the leader in price\perf, it comes down to how desperate they are for sales! NV can cut prices too, however they dont need to in order to keep up sales.
Doesnt seem so grand for the manufacturer when you look at the measure in that light!

I am not Nvidia. Nor am I AMD. I am an end consumer. Therefore I am most concerned with getting the best value for my money.

Everyone has their own definition of value and it's not just FPS/$ for a lot of folks.

I can't see this being the 380x. I think WCCFtech has it wrong here.

Don't you think that a 390x at 300W is a lot?
I can see a LOT of people disqualifying the card, irregardless of performance, due to the powerdraw.

It'd require many people to upgrade their PSUs (outside of the heavy enthusiast forum users) in order to run such a card.

It'd be quite interesting to see what would happen if AMD went all in on performance on the desktop 390x while had Fiji aiming at efficiency for a 380x.

I'd be happy if they at least publically state the TDP.

Would people purchase it though? I mean rather, would Nvidia owners here currently seriously consider a 300W single GPU capable of 4k gaming that's a MASSIVE increase over their GTX 970/980? Whether or not we even have 4K monitors is irrelevant even, with VSR/DSR.

Could this be enough for AMD to gain the efficiency, and GPU crown in one fell swoop? Or will it massively backfire on them with high end users refusing to use a massive power draw card like that, and the efficiency card suffering due to poor marketing (lets be real it's a possibility) and suffering because the high end card has a massive power draw, so by association the mid range card has poor efficiency as well?

 

[Erenhardt]

Many more will do it because of the price. If its 300 Watt beast that is faster than 780 SLI, it will be pricey.

It'd require many people to upgrade their PSUs (outside of the heavy enthusiast forum users) in order to run such a card.

That is the point. No one will have to upgrade psu since only enthusiast go for top of the line product aimed at enthusiasts.
Regardless, 600W PSU is not an enthusiast thing.

You see. It's not how it works.
You can have a card that takes 400Watt and still it could be the most efficient card out there.
Huge power consumption doesn't mean inefficiency.

If 390X uses power efficient HBM, which in turn makes it run lean, will this be directly transfered to 380X which will probably sport old GDDR5 (possibly refreshed hawaii?). Because I expect the influence going from bad product to good product when it comes to amd products - there is heavy contra-marketing going on to enshoure that.
