nVidia 2015 mobile speculation thread

I don't have my laptop to test and probably won't for awhile...

Every system I've seen that popped (this has apparently been going on since the preview and not just laptops, lots of complaints of desktop corruption too) was running UEFI. BIOS via the CSM should not allow such low level access but I'm not willing to risk my panel to test that theory.

 

I understand but what I don't know is why have I not been infected. I've been using windows 10 since build 10130 and while it had its quirks, it was mainly functioning well and the official build was a breath of fresh air. That just makes me want to download windows 10 again but then if my luck runs out, I'll be screwed

 

I wouldn't risk it. There aren't enough features to justify risking a brick.

 

Yup, you are right but what about DX12 and DX12 only games like ashes of the singularity?

 

Ashes of the Singularity supports DX9-12 so you're covered there.

DX12 will not run all that well on 880Ms or any nVidia GPU right now - its highly optimized for AMD cards with their asynchronous compute capabilities. In DX12 mode, a 290X beats the 980 Ti thanks to that omission.

 

Yup, I read that somewhere: http://www.game-debate.com/news/?ne...o Not Support DirectX 12 Asynchronous Compute

 

Not exactly "optimized" in the sense Nvidia usually uses it. They pay software engineers to be on site to make sure the game fully uses their cards for directx 11. They did not design Maxwell architecture to utilize asynchronous processing in the way amd has pushed for years. Because of this, amd is better, but not "optimized"in the traditional sense. Nvidia just refused to work with the standard creator, Microsoft had to respond quickly to mantle and opencl supporting this in Vulcan. So, they adopted part of how mantle works, which benefits amd because it is made for their architecture.

 

And we, NVIDIA Users, are once again left in the dirt. How charming, brings tears to my eyes (literally :'()

 

Recently, Nvidia has, mostly, been the go to card. But memory standards, etc. Are created at amd. Nvidia makes proprietary to drive up price, disadvantage amd, then, because they have the largest market share, get the designers to adopt their proprietary standards, tech, etc. They've been holding amd down, which is why they say amd is "brute force." It has to do more processing to get the same results as proprietary Nvidia standards. Microsoft has usually helped promote this, but couldn't lose market to openCL. They didn't have time to help out Nvidia.

Edit: Obviously, brute force isn't only what they are doing. They designed an elegant asynchronous processing solution that only now designers and api have adopted, now meaning Nvidia has to design on this line, but they are years behind on practice in development.

 

Quote from the Windows 10 hate thread... very relevant to the discussions here. Things are not OK and they are only going to get worse as we move forward sideways. We need to start focusing on Linux and abandon Micro$lop's trash. They are so focused on having a command and control environment that they are no longer worthy of maintaining relevance among the technically competent and enthusiast groups.

The AMD Fury runs nicer than a stock 980Ti, but all the reviews I have seen show it's really a turd when it comes to overclocking and gets its shiny little heiny torn off and handed back to it once the overclocking starts. I'm not OK with using CPUs or GPUs stock. If that is the only way they work right and they do not respond well to overclocking, then they are garbage as far as my purposes are concerned. I don't want a belly-button computer... might as well go back to console gaming if everyone gets to have the same flavor and a leveled hardware playing field that only varies in performance based on the amount of money spent. Really, at that point, why care if everything is the essentially same with a different wrapper on the outside?

 

Actually, it's not optimization in the regular sense that favours AMD here as much as their GPU's being a lot better at parallelism on a hardware level compared to Nvidia (which didn't push for this almost at all).
Mind you, software optimizations do play a certain part, but likely not enough to make a crucial difference because DX12 is already close to the metal.

 

Also, that's just how one game uses DX12. Others may lean on other features of the API more heavily than asynchronous compute. We won't know until some more games are released.

Pascal & Arctic Islands = full DX12 support. That's all you need to know.

 

Not quite. Head to head dx12 benchmarks of those two are all I need to know. I don't know Nvidia will be fully up on all parts. They are doing their first architecture using asynchronous processing, something amd has done since 2012.

Interesting bit of trivia: AMD doesn't support DX11 Multithreading. Has it hurt them in games? Nope.

 

That could be why their DX11 performance has been less than stellar.

Where?

 

He meant that if optimized, amd may have better bench scores, etc. Doesn't mean not competitive in some way.

 

Yeah, multiple sites (like pcper for example) have commented on the poor CPU efficiency of AMD's current DX11 drivers. So it's really good to see that they have competent DX12 drivers.

Might be wrong, but I see this as a rather calculated move by Nvidia.

There is no comparison with AMD cards for DX11, so they currently have much larger market share. Then by the time DX12 games are the standard, Nvidia will be able to demonstrate tremendous gains in performance with their first architecture that incorporates asynchronous compute (whether it is Pascal or Volta) over Maxwell.

So if you just shelled out hundreds of dollars on 980Ti, GTX 980, or GTX 970, Nvidia will persuade you to buy next generation card, much more easily than AMD will persuade owners of Fury or R9 290X, etc., to upgrade, since the performance improvement won't be as dramatic with AMD cards.

 

You have yet to answer my question and list examples of already released games where AMD performs significantly behind Nvidia due to not supporting the multithreading features in DX11

 

I really really want AMD to make a comeback, hoping for it.

 

AMD performance not living up to its full potential is the point I'm trying to make. Not how their products compare to NVIDIA.

Sent from my XT1562 using Tapatalk

 

It's all relative. Without Nvidia to compare to, how can you say that AMD is not living up to its full potential, or that their driver thread consumes more CPU time?

 

"It’s undoubtedly clear from our data that NVIDIA has vastly superior DX11 drivers when compared to AMD. DX11 is an API that requires a lot of optimization for games and for multi-threading and it would appear that NVIDIA’s engineering team has spent a lot of time and resources making sure there is the fastest and best performing platform."

http://www.pcper.com/reviews/Graphi...ted-Ashes-Singularity-Benchmark/Closing-Thoug

-----------------------------------------------------------------

"Meanwhile this setup also highlights the fact that under DirectX 11, there is a massive difference in performance between AMD and NVIDIA. In both cases we are completely CPU bound, with AMD’s drivers only able to deliver 1/3rd the performance of NVIDIA’s."

http://www.anandtech.com/show/8962/the-directx-12-performance-preview-amd-nvidia-star-swarm/4

-----------------------------------------------------------------

"Thanks to some well-judged price adjustments and the recent arrival of 300 series graphics hardware, the red team has worthy hardware to compete with most of Nvidia's product line, but what's become increasingly apparent over the last nine months is that AMD's DirectX 11 driver is sub-optimal, particularly relevant for those looking to build a budget PC - an area where AMD offers the best theoretical price/performance level in the market."

"However, in CPU-limited scenarios, AMD's hardware is let down heavily by the sub-optimal driver, meaning that in many modern games (but we should stress - notall), Nvidia's less capable parts actually hand in more consistent performance."

"Nvidia's driver is processing the same draw calls much more efficiently than its AMD equivalent, maintaining high frame-rates and leaving more CPU resources open to the actual game logic."

"In the graphics market, AMD has often been criticised for its lacklustre approach to driver support. In truth, both vendors have their issues, but in terms of DX11 driver efficiency, Nvidia is still significantly ahead."

I've never paid much attention to whether AMD GPUs were optimized well compared to NVIDIA. It was so hard to get past the fact that they overclocked poorly, malfunctioned so often, and frequently died prematurely that optimization never really made it to my radar screen. Now that NVIDIA drivers are mostly crap and they throttle because of screwed up firmware (even though they claim this to be a power conserving feature) the playing field is a little bit flatter than it used to be. I'm not sure what is worse now... my LCD screens getting ruined by Windows 10 + NVIDIA drivers, my 780M SLI throttling because of screwed up GeForce drivers, or an AMD GPU not working right and permanently assigning me to a second-fiddle position on performance. I wonder if we will ever actually look back on these as the "good old days" LOL?

 

Pretty long-winded way of repeating what I said

 

Unlikely there are any new cards this year. Technically possible, but very unlikely. But this is good because Pascal may come early!

http://forum.notebookreview.com/threads/brace-yourself-new-maxwell-cards-incoming.757332/

Check the dates on those posts. In July, we had confirmed the entire Maxwell lineup before it even launched*, and we haven't even seen a new hardware ID for the 990M, nor have there been any other sources which do not lead back to the main post of this thread. Part of me was hoping there would be.

This, combined with the fact that new Clevo's and other laptops are launching with the 970M and 980M, sway me to believe nothing new is coming.

*The same for Kepler as well.

 

Pascal uses hbm2. NO ONE WILL HAVE A CARD WITH THIS UNTIL NEXT SUMMER!!! Theoretically June is possible, but Q3 is more likely.

Edit: so, to explain, Nvidia taped out in June, as did AMD. This means the first ES this month for both companies. Nvidia is signed up on the list for production at tsmc. AMD was not seen on that list. Doesn't mean they won't use tsmc or weren't, just what the reporter saw. This also started rumours of amd using glofo or Samsung process at glofo. Not confirmed. From tape out to market, it takes 9-12 months. As finfet is trickier, may take time getting yields right. But this puts out to market late Q2. Nvidia isn't magic, it doesn't violate the rules to get to market.They made 9 months with Maxwell. But that was on a developed, fully mature process. Here is injecting hbm2 and finfet at a new node. All I'm saying is don't expect miracles!!!

 

My non-throttling 800M (thanks to svl7) isn't looking so bad now.

 

Your hard mods didn't hurt

But the 780M SLI issue appears to be an Alienware issue unless I've missed P570WM owners complaining about it. Stick your 880M in his Alienware and see if it throttles.

 

Trade that 880M to someone with a 780M who doesn't know about its issues and thinks it's better 'cause 8 > 7. Win!

 

This could be one of the 990m laptop models


Boring boring Chelsea

 

OMG have Asus lost it? Wtf is that external graphics dock? Looks huge!

 

Dude, that's a water cooling radiator...


Boring boring Chelsea

 

It looks like the asus grew a tumor.

im all for bringing back laptop docks but come on.

Looks like a GM204, any mention of form factor?

17 inch with 4K IPS display. pricing is not official yet, but they mention thats its gonna be around 4K

edit: oh, u meant GPU form factor, duh nope, no mention of that. im presuming soldered though, seeing as they coupled it with a BGA cpu...

 

geeze, first laptops with mechanical keyboards now this. whats next? when will the madness stop!

though its nice to see exparamentation again.

First real GTX 990M leak. Excellent find.

So that would kinda explain those earlier variable TDP rumours: lower values are with air cooling, highest values are only possible with overclocking and external water cooler (that article mentions 80% higher performance when docked).

 

I love it, looks like something Morena Baccarin from V would use, more alien than Alienware.

 

Yes, sir. Sometimes I forget that I did those. They aren't obvious unless viewed from the bottom.

I will stick the 880M in my M18x R2 for testing this weekend. The machine arrives on Friday. The 3940XM came yesterday.

I can totally imagine the hardcore desktop folks like "these desktop replacement laptops are getting out of control".

 

My god, this laptop has to have one of the nicest butt.......mhhhhh I mean rear I've ever seen in my life. @Mr. Fox , your new laptop, imagine the overclocking capabilities on this water-cooled 990m beast. I wouldn't be surprised if it's actually more than 6K USD though considering one 990m is roughly speculated to be around the 1600USD price range then add 1-1.5K for the water-cooled Kim Kardashian butt...........mhhhhhhh I mean rear of the laptop.

 

And changed gender too, so now you are a 70 year old grandma

 

I wonder if I will be able to replace my 680M SLI in the M18x R2 with 990M SLI? Any thoughts on that?

Sent from my SPH-L720 using Tapatalk

 

I think the leading consensus is that the 990m is going to be solderd only.

Sent from my SGH-M919V using Tapatalk

 

Yeah, looks like this GX700 version is soldered. Shame.

Also, seems to be a special card for certain manufacturers only.
