Radeon R9-M295X

Won't do well with Planetary Annihilation then! That is only OpenGL ! Or perhaps I am wrong..

 

so what we all waiting for tonga? R9 M295x? lets hope theres a huge temp drop as it'll be good for my mod.

 

You mean OpenCL not OpenGL. Nvidia has had better OpenGL drivers since like Doom 3 LOL, and it definitely has better Linux drivers.

 

Ah yes my bad

 

You know what could make this card much sweeter:
20nm

Several sites are writing that Tonga is 20nm. While other say it is 28nm. So there are some chances that we could see our first 20nm GPU soon.
Other interesting features it may have is HBM. Basically a ton more memory bandwidth than what current VRAM can offer.

Im really interested to see what AMD can bring to the table with this card.

 

That's just the rumor mill IMO. AMD already announced that they would be sticking with 28nm this year: http://www.techpowerup.com/mobile/200089/no-20-nm-gpus-from-amd-this-year.html

But we'll see.

 

Indeed. I think you are right.

However unlike NVidia AMD haven't released a new card since the 7970M. 8970M and m290x are exactly the same chip. The 780M was an upgrade over the 680M

This makes me a little hopeful that AMD will bring after 2.5 years something tasty to the table. The better the card is the better the Maxwell response from NVidia too. We ALL should be routing for AMD at this point! They are the only ones able to drive prices back down and give us consumers a good deal for our money whether it be NVidia or AMD cards.

 

I think it better be 28nm rather than 20nm.
28nm at 100W >> 20nm at 100W => 28nm has bigger die than 20nm => 28nm will be much easier to cool at the same TDP, meaning better overclocking.
Besides if this is based on GloFo 28nm and already has awesome efficiency, then imagine how much better GloFo 20nm will be next year.

Yes, as has been said, whatever AMD does to up the ante with the next-gen card, ESPECIALLY if it is 20nm, is only going to drive the competition & market that much more. It's a win/win for everyone involved here, and with AMD's lower pricing model in place, it's an even greater win for the AMD customers, too.
If the early word and speculation about the 295x's abilities are true, and an average of 25% in increase in performance over the current Nvidia 880m leader, it would then nullify most of the other advantages that Nvidia still currently has over AMD in gaming- ie, Physx.
It means that for games that are PhysX enabled, you can switch that on in the game with the 295x, and not see the huge FPS drops currently seen with other lesser AMD cards that makes game unplayable in that situation.
This is a great thing to look forward to in the fall, if the speculation about the timing of this card is correct.

 

does no one feel a little strange with this 800mhz base clock? it just seems too low considering r9 m290x is 900mhz and 880m is almost 1ghz; it certainly can go higher to 900mhz with no problem. this better not mean the start of another rebranding cycle of 2.5 years.

8970m is a rebrand of 7970m OC'd, m290x is a rebrand of m290x with a driver update.

if m295x does come out to be 800mhz, then chances are AMD is gonna be all set for another 3 years

for those who think it's gonna lower price by bringing more competition on the mobile platform? very unlikely, amd doesn't need flagship gpus, it needs to fill in the gap for mainstream gpu to bring the price down, top end products don't affect nvidia much at all

 

When using an AMD card Physx runs off your CPU, so I see no benefits to having a more powerful AMD card while playing any Physx game. There won't be any difference when compared to previous AMD cards in this respect.

 

If the M295X is 20nm, and only 25% faster than the GTX 880M, it's an abject failure of a mobile card.

 

It will be 28nm.

 

________________________________________________________

Yes, I am aware of this, however, there is going to be a much lesser hit in gaming with a must faster M295x in trying to use PhysX than with previous AMD models, if the early word of it being 25% faster than the 880m is true.
It's going to process the extra data better and faster than, say, a 7970m would, for example.
The M295x would shuttle off that extra data to the CPU at a faster rate and speed, and would help keep the big drop in FPS to a smaller level than ever before.
With my 7970m, the performance hit was about 60 FPS or so in-game, making it completely unplayable.
There is still going to be a hit to performance with the M295x, but the overall drop in FPS, I believe, will be much lower than before, and thus make it more playable. How much less of a hit isn't going to be known until it comes out in the Fall.

 

I doubt it will change anything, what is CPU limited will stay CPU limited, best thing to do is forget about PhysX completely, its not very useful anyways.

 

^This. I wouldn't anticipate any noticeable difference.

 

The drastic FPS drop was because PhysX was murdering your CPU. Getting a faster AMD card isn't gonna help if you're missing the CUDA cores to do real GPU-powered PhysX.

 

highly doubting a 20nm coming this year

 

definitely not for amd

 

AMD has a higher chance to release 20nm GPUs first thanks to moving GPUs to Globalfoundries. Still don't expect neither GloFo nor TSMC to have production ready 20nm GPUs with decent yields until next year.

 

not for nvidia either i think. dont really wanna get anything unless a decent amount of power efficiency and temperature improvement.

 

I would add compatibility to this equation.

 

Games seem to look and play perfectly fine without it. I agree! Besides for those of us with older gen cpu's. The last thing we want to do is shunt unnecessary work to the cpu. It would fast become a bottleneck.

 

Yeah PhysX is a gimmicky glorified garbage and debris engine.

 

But I want to see individual sheets of paper!

I hope they standardize that and use open resources instead or proprietary tech in the future.

 

For this to happen, Mr Sweaty Forehead would have to quit Nvidia.

 

Ever heard of "black don't crack?" Well, it's the same thing with Asians.

 

Well don't we all, but looking at Mantle, G-Sync, TrueAudio, PhysX, and so on, I guess the industry doesn't feel this way.

 

Actually if something has a lot of merit like gsync then there is a free version if that hitting for every card with a compatible display.

 

But FreeSync is limited to GCN 1.1 and later and Nvidia support is unknown, so an even narrower range of supported hardware than G-Sync.

 

well 1st gen i7 to the newer ones does feel a bit slower but as for sandy or ivy, almost no difference to haswell tbh, especially with haswell runs hot can't even clock that high.

 

Indeed. This is why I run mine at sandy bridge and ivy bridge levels


On the go from my iPod touch

 

btw your signature how do you get 920xm to 4.0ghz?

 

Yeah that 920XM must be on fire LOL. The i7-920 already ran pretty hot when pushed up to 4 GHz. Now imagine that in a laptop.

 

Not at all. I run my 920xm with +160mv this by connecting a vid to ground.

At 3.6ghz(27x) across all cores and then 28x3, 29x2 and 30x1 I do not get past 70-74c in any game. This with my cooling not even at its limit. I can run it at 28x4 using handbrake to encode movies in ambient 25c and keep it around 95c.

Very cool all things considered. In fact I intend to bump it up some more due to how stable it is! Don't underestimate good old nehelem!! sandy bridge and ivy bridge performance I now have even though I will have a higher energy bill at least it will help heat the house in the winter.

I just hope that something bad doesn't happen and your laptop causes the whole house to burn down .. That would be a very expensive overclock lol..

 

I'd like to point out the i7 920xm and i7 920 are actually quite different chips. The XM was more related to the 8xx series desktop CPUs.

 

Yeah, 920xm was based on lyndsfield or something right?

Also, I do remember being able to push the 920xm quite a lot on stock. I had mine running at 3.2 - 3.4ghz all 4 cores at 85 or so Temps without doing anything else except raise the multipliers on the GX660R.

But I think even at such OC, I was reaching barely Core i7 2700mq levels of performance.

 

Wow many nay sayers here! The 920xm is a hardy chip it can take the voltage.

Nope it won't burn my house down I cool it properly for the second time lol ...as for performance according to passmark it is the same as the 2920xm at stock when I run 28x across all cores.

Not actually that far behind the 4700mq which is pretty incredible. Anyways I might just push it to 29x across all cores in the future then we would be pretty much neck and neck!

Sandy and Ivy have done wonders in terms of reduced power consumption. However revolutionary performance gains...I think not. Only the 2920xm,2960xm, 3920xm,3940xm and the high end haswell 4800mq and up beat this old chip by far. The others...meh.

 

10-15% per clock advantage going from the xxx to the 2xxx chips along with a large reduction in power consumption.

 

Indeed! .

 

waiting for broadwell and see how well it does against ivy and haswell. and waiting for tonga and maxwell, expose the secrets soon. if GPU chip itself can run cool i can likely stay 4cores no HT at 4.9 and still stay under 85C with both fan maxed out.

 

Does it save power to turn HT off? How do you do it? How much performance difference does it make?


On the go from my iPod touch

 

You should be able to turn off HT in the bios. HT will use less power under load. But of course you will loose any (if any) advantage that HT would have enabled.

 

Sure M18x R2 users WITH unlocked BIOS can turn HT on/off as they please but for the rest of us plebs that BIOS settings is almost always unavailable

 

The heat is not the issue.. Its the amount of voltage your using which can short/reduce lifetime of components...

 

People ran the desktop chips at that for ages.

 

I was under the impression laptop chips have less tolerance for high voltages unless they are XM?

 

That I did not know.

Meh.. Looks how old his chip is .. and still going strong

 

And that 920xm will still be a alive for more time to come
