Radeon R9-M295X

New rumors are that the entire 300 series will be based on new GPUs, so maybe new mobile GPUs incoming in summer.

 

Yep, correct. Word is that they originally planned to only push out one new GPU, 390X, but investors took out their pitchforks and demanded a new direction because of the falling sales. So AMD board made a decision to ditch previous plans and release several new cards.

Not an easy choice because they wanted to remove current inventory (290X rebranded as 380X for example), but finally we might see something new from AMD in mobile too

 

Brilliant! I hope they all have HBM RAM, 4096 bit memory bus is simply insane. I don't care how many transistors the Titan X has!

 

Mammoth amounts of memory bandwidth is nice and all, but you really need a core that's powerful enough to take advantage of it in the first place. Increasing memory bandwidth alone is not going to automatically increase performance by a considerable amount. I hope AMD can deliver a nice and power efficient core to complement the HBM memory

 

I think that as far as we know, only the 380X and 390X will have HBM... main differences between the two though will be in core count.
Apart from that... other GPU's in the 300 series will likely have new architectures... but we currently have no indication about them using HBM (let's hope they do).

 

A hybrid would be interesting, 2GB of HBM plus 2GB 128bit GDDR5. The current HBM is limited to 1GB per stack and such a large memory bus on a mid sized core would be extremely die intensive.

 

I think it isn't very die intensive at all, someone posted numbers in a comment section where he listed the 384 bit Tahiti, 512 bit Hawaii and 4096 bit HBM Fiji (approximate) memory controller sizes and Hawaii was slightly smaller than Tahiti and with HBM Fiji was much smaller.

 

how much of an impact will HBM have on 4k gaming?

 

A lot but as cakefish pointed out, you would be bottlenecked by the core, which wouldn't be able to utilise all that lovely memory bandwidth.

 

Crossfire systems will scale REALLY well and fly though.

 

If anybody remembers me saying this, well, I'm psychic.

But hey, a "free" laptop costs you nothing. You gain more despite what brand it's from.

 

Have you heard about rumored power consumption of new 370/370X? Nice drop from Pitcairn rated 180...

This should be little stronger than M290X and should be somewhere between pathetic 965M and 970m I suppose.

 

I'm quite sure the 370X will troll both the 970M and 980M.. Especially if it's using a new GCN... let's wait and see though!

 

Really? I have no faith in AMD at this point, especially in the laptop sector. I'd welcome the competition but forgive me for being pessimistic about AMD's capabilities. Although I'd be lying if I didn't say that I hope it's true so it forces nVidia to stop with their anti-consumer practices and maybe even forces them to launch their full GM204 card sooner!

 

Why shouldnt AMD be able to make an efficient architecture like Nvidia?
The reason I have been bashing AMD since the first M295X leaks came out was because I knew it would have a high TDP against Maxwell. But we are talking about a company thats been fighting against Nvidia for many many years. Im sure they are capable too. Eventually. And now its bloody time they come up with something worthy

Congrats/sorry about the moderator status btw

 

They don't have the cash that nVidia does for one. Their market share is plummeting and they've lost the trust of consumers and OEMs alike, isn't that what spurred them to release a new architecture anyway - upset shareholders?

 

True but the more reasons to torture their engineers to come up with a great product.
If they lose GPU race, they might as well just give up. Its the only department thats been keeping them from falling to 10 cents per share

For GPUs they have indeed lost some OEM backing, but Clevo/MSI/Dell are still loyal to them. Asus is the odd one here, only using Nvidia products. With an efficient architecture Im sure we will see AMD cards in many notebooks again. OEMs avoided M295X because of its poor thermal/power I think. Cant blame them really

 

I'm not disagreeing with you at all, I'm just thinking if they had such an architecture ready to go, why didn't they release it earlier? I'm just afraid we are going to have a rushed to market incomplete product. AMD has done it before. For the sake of competition, I hope AMD proves me wrong before nVidia and Intel destroy them.

Edit: just saw your post edit - thanks for the congrats and yeah the M295X is my reference point as well. I don't see why they bothered if they had an ace in the hole ready. It made them look really bad after the long rumor mill...

 

Funnily enough, the last truly upgradeable (as in both CPU and GPU) ASUS ROG notebook was the last one with an AMD GPU, the G73JH

 

Isn't the overheating with said AMD GPU part of the reason that ASUS said no more though?

 

The overheating was due to the poor stock thermal paste and useless factory application.. With proper IC Diamond paste, I had 0 overheating problems and never needed to repaste for the 3.5 years I owned the notebook for.. If anything, only Asus is to blame!

 

Unlike Thermi, the 5870M wasn't a hot GPU. It was the poor factory paste jobs. People were literally seeing 25C drops after repasting. I was one of the lucky ones, my G73JH never overheated out of the box. Who knows if the large number of service requests was the reason ASUS switched to Nvidia GPUs after that, but the G73JH had a bunch of other issues that had nothing to do with GPU overheating. The main one was probably the defective factory vBIOS that shipped with many units, which would cause GSOD in games with newer Catayst drivers and required a vBIOS update to fix. It had a really rocky launch.

What's funny though is that after switching to Nvidia, ASUS raised prices dramatically and at the same time, stopped using flagship GPUs for 3 whole generations. They were all mid-range cards. G73JW/SW had 460M, G74 had 560M, and G75 had 660M/670M/670MX. Needless to say, this pissed off a whole bunch of ASUS fans. By the time ASUS returned to offering flagship GPUs with 780M in the G750JH, it had stopped using socketed CPUs.

 

25C?! Jeez! How is it even possible to screw up a paste job that bad?!

 

Outsourced, below minimum wage labor in third-world country sweatshops

 

Pure words of wisdom there. I agree with you completely.
