AMD will use 28nm for their GPUs in 2015

Yikes. It means that M295X is the best AMD most likely will have in 2015 since they have no new architecture. Additionally, since Fiji (390X) is the only one thats new, they can`t have done much progress with the architecture either, because if they did, they could easily have built new 380X and 370X and not just rebrand existing Tonga/Hawaii cards.

This is not good!

 

Hmmm... Tonga again for mobile, eh? This doesn't really leave any opportunity for improvement over the M295X unless they pull some kind of miracle and base it on a 20nm process.

I think we can safely assume that Hawaii and Fiji are too power hungry for mobile use.

Really don't know what they have planned for M390X...

The 300W for 380x/390x seems to be too high for notebooks.
But AMD has a tendency to report maximum TDP for their components... so how much a chip would use up to maximum if properly stressed.

This might indicate however that if the GPU which used 300W has HBM is probably same architecturally-wise anyway to previously released GPU's, but that the only thing which changed is basically the implementation of HBM for high resolution gaming as well as more shaders.

Having said that, given that the shader count is quite high for HBM card, which would likely contribute to the large power draw, might indicate that the architecture itself is the same like in 290X/295X.

If this is the case however... then I don't think we will necessarily see any mobile solutions based on HBM from AMD anytime soon (at least, it doesn't necessarily seem like they would be released this year).

 

I agree, it looks increasingly likely that HBM will be next year's hot thing in the laptop domain, once 14nm and the new architectures arrive from both teams.

Like with almost everything these days, desktops probably get it way before us :/

Agreed... however, AMD might just end up rebranding the R9 M295x later in the year to have HBM.
Given how HBM would reduce power requirements as well as overall space on the card (memory-wise) by about half of what they are now... the gpu in question could end up with a lower power draw.

How low, I don't know.
It might go down to 100W or more... or it could go down by a negligible amount ... which would of course mean a same R9 M295X GPU as it exists now in limited quantities (and is reaching high temperatures and throttles due to inefficient cooling and power supply) only with a lower power draw and better performance in gaming (I don't know whether it would be high enough to reach 970M and 980M though).

But this would depend on how much of a power draw difference is there between GDDR5 and HBM TDP wise.
HBM takes up about 50% less energy compared to GDDR5... how much of a benefit in terms of power reduction would this translate to a gpu with GDDR5 which uses 125W in total?

 

They can forget about mobile alltogether if they plan on using M295X for the entire 2015. Thats like throwing out meat for the wolves.
Nvidia got M295X beat by roughly 50% with GTX 980M and the GTX 970M that have a tiny 75W TDP is roughly 20% faster than that 125W M295X.

AMD can`t even win with a price war this time either, because you can get a GTX 970M for $450. Dell charge the same for machines with 970M and M295X.

AMD need a new architecture. Nothing more that needs to be said. Its the only way to be able to compete in notebooks. Desktops? Have a inefficient architecture? Just produce a bigger chip with more transistors and bigger power consumption and you let the performance charts do the talking. Although Maxwell got it beat by efficiency, they will still be able to sell GPUs due to performance if the price is right

 

Where are you getting those results? I can't see such difference in the Alienware 15's benchmarks - THE ONLY system that has them both and TESTED! Both are choked mainly by the power supply! We know how far the 980m can get, but we don't know the exact level of the M295X. Till then it's better to use results from the same system!

Otherwise I agree, I can't see a new chip coming to mobile this year. Although I hope they'll pull a miracle and make a custom one, like they did with FirePro M6100.

New rumour is exactly the opposite of the previous one. All GPUs in the 300 series will be brand spanking new. Naturally, that would benefit the mobile side too.

Which really only serves to show how little anyone outside of AMD actually know about these things.

They are concerned with price only.

Hehe... I was just about to post this exact link on the 300 series.

Its good to know the new gpu's won't be rebrands... but it would be better if they were released earlier.

 

I find this much less believable than the previous rumor, plus 3DCenter is a more reputable site than WCCFTech

 

Excellent news if true... Go AMD

 

I wish I had a way to celebrate. For me, the fact that they're all new makes up for their being postponed.

 

Nice find! Awesome if true.

 

Here it is, undoubtly a coming mobile GPU that unlike M295X, OEMs will use.

R9 270: 1400 shaders, 256 bit. 120W.

7870 (M290X): 1280 shaders, 256bit, 190W

I think the mobile card based on this new efficient architecture will be a mid end R9 M380. The R9 M390X will have much more cores

This will be interesting.. let's see how it goes!

 

Not sure where to drop this rumor so I´ll post it here:

http://www.tweaktown.com/news/44684/amd-radeon-r9-390x-rumored-very-short-supply-launch/index.html

 

Why 4GB? Plenty of games nowadays can run out of VRAM with that. Or maybe we have to wait for 8GB premium versions again?

 

Sounds a bit sketchy, especially most rumors and leaks we have right now point towards the 390X outperforming the Titan X. Also, a dual-GPU card launch with the single-GPU flagship? Unlikely.

 

And the old thread was just closed. Apparently most had given up on AMD. Time to open a new thread and not close it this time

 

Even if every AMD mobile this year turns out to be rebrands we still need a place to discuss it imo.

 

Discussion is fine but rumor threads that go too far off topic should be expected to be closed. This is nothing new, we have had many speculation threads be locked because they get out of hand when people got bored and started to attack each other or run them so far off topic that cleaning up the mess would be more difficult than closing it.

Also this is not about mobile and really belongs in the desktop section of the forum. I will leave it alone for now because it will get more views here but if it becomes another off topic thread, especially if the bickering starts again, infractions will go out and we may decide to lock the thread again.

 

Fair enough. I still think that particular info is mobile-related. If the coming desktop flagship will be in extermely short supply until 2016, presumably so will the mobile version.

 

My point is that it doesn't talk about the mobile chips at all but yes, if there is a desktop delay there will be a mobile delay as well unless AMD plans to launch their mobile part first which makes no sense.

 

This rumor is outdated. It's already known that AMD delayed Fiji so it could incorporate HBM 2 (up to 8GB VRAM).

 

Recent rumors point to M385 being based on Tonga so there is still the possibility to see M390 series based on a new GPU.

 

hahaha thanks for the laugh.
AMD should hire you for strategic decisions. Why launch 390X with HBM1 now when they can just wait to 2016 and use HBM2? Its not like they need money now right ...
