So I guess 485X is about 970M performance, 490 - 980M and 490X - 10-15% faster than 980M. If only 490X is priced at 970M level, it's not that bad, but once mobile Pascal is out, these will be utterly destroyed.

This reminds me of Nvidia's GTX 800 series - they rebranded so much that they skipped the series numbering for the desktop versions...

490 and 490X will probably be exclusive to the iMac 5K.

This was pretty much confirmed a few months ago and I think that it was from you (in the mobile Polaris thread). What the table was lacking back then was the M480(X) and M490(X). As far as I can see, it's still lacking them, so - nothing to see here, another useless "news flash" topic.

Man, if AMD is going to combat the GT 1040M (960M performance rumored) with another generation of rebrands, they are freaking hosed.

AMD had 3870, 4850/70 and 5870 back then. That was the only point people gladly bought 5870s, and then again not all of them. There still were the ones buying the burners that 480m and later the 580m were (approaching near 100% failure rate as the history tells).

Actually I'm making things equal, because everyone points finger and says - AMD bad. I doubt that lack of AMDs has anything to do with 7970m. The mother of all failure rates the 8xxx series, happened and OEMs were still using, and continued to do so, nGreedia. Is there a laptop with original (not replaced) 580m (675m)? Since you mention that we live in properly cooled times, what makes the 980m failures then?

The 3850/3870 also those solder issues in desktops and the 4xxx series weren't perfect as well. In the end I saw no Nvidia card dying after the 8xxx series and I had a LOT of cards and I am quite the heavy user. the 78xx and 79xx AMD mobile gpu's have poor flipchip quality though.
Blame the EU for this with the law for banning solder based on lead.Last edited: May 17, 2016transphasic and TomJGX like this. -
What if I call your post bullcrap? Is this the way to make discussion? The PS3's GPU is made by nGreedia. I'm a heavy user as well and I haven't had a single ATi/AMD fail on me. EVER. So my word against yours. But yes, I know where the problem is, I'm just saying that things are equal and I said it a few years ago, but everyone was laughing. Only now people are starting to realize this. Even with fourth and fifth player the problem would still be there. That's why I'm saying people have to know about failure rates of either brand, but people tend to forget to mention that nGreedias fail and only point at AMD. Lastly is there an official units sold vs failure rates (not estimates) from a reliable source? I don't think so, but in a country like mine where it's still cheaper to repair than buying a new thing, there's something close to it, it's called service centers. Still there are people that couldn't be bothered, or don't have the money, so again, there's no reliable source to get info from.
TL;DR My point always was and would always be that things fail and people should know. The reason I point at nGreedia is because everyone else points at AMD!Takaezo likes this. -
Hard to take you seriously, when you use immature terms like nGreedia.

Because? You are calling me, or the terms I'm using, immature and your very next sentence is immature. I would love some argumentation.Last edited: May 18, 2016 -
How about we take this down a notch and focus on the M400 instead.

Well, I think it's time to start fishing of do sth else instead of "hoping for" AMD. Nvidia just dominate the market(btw nice prices for new series...)...
-
I had a HD 3850 die by the way because of the same reason a Nvidia 8800GTX would die. -
Well I had HD 3650 both in my laptop and my PC. Both were alive (the PC is still around, but not used). The Mobility has seen 3 hour sessions (sometimes more) of BioShock @105ºC (because Spain) for an year and was still alive when I sold it. Should've kept it and put it in a frame. It deserved it.
As for the reliability of newer GPUs - that's why I'm vocal about it, there ARE failures. More than anyone is willing to admit. Especially for 980m. For a while now I was wondering if I should make a topic, but I'd guess not many would post... if any. People are sealed shut if their nGreedia fails. And then why AMDs market share is shrinking - lies, lies, lies, either from the EvilCorp (nGreedia, to avoid confusion) itself or the users (because resale value, unwillingness to admit that their mighty glorious has fallen, whatever).
Ironically a friend's 7970m* has failed yesterday, but we'll fix it and the new chip would have lead balls (pun intended).
*Bought from a forum member and I think that it's well over 2 years, probably 3, and more than an year of this time was running @~85ºC. Not sure at what temps was running at the previous owner.Last edited: May 18, 2016TomJGX likes this. -
Goes to show you BGA manufacturing is still heavily flawed. I expect this issues to continue as BGA laptops made in 2014-2015 will start exhibiting this behavior in a year or two.Last edited: May 18, 2016 -
This is about reballing/reflowing GPU's or other chips.
This is from someone actually repairing pcb's for a living. As you can hear in this video it has NOTHING to do with the solder balls on the BGA package itself. It is the solder on the flipchip. Reballing heats up the chip and also the solder inside the flipchip itself thus letting it run again. This created the whole BGA myth. A friend of my working for Nvidia and being an advisor for super PC's would love to explain it to you in full detail.
Its a combination of multiple factors, bad solder, bad chip design, poor thermals.
Now thermals are not the issue anymore since we have much smaller and more efficient chips now. It shouldnt be a problem with for example the 8800GTX as well. But it was due to the change of solder because of EU regulations. They have fixed that by now. Thus leaving 2 other options open. Bad chips design and poor thermals. With the Macbook Retina's both was the case unfortunately. The chips where vulnerable for this.
To back this fact up even more. The past 4 Nvidia generations run reference at 80C under load. The fan profiles are tuned for fan noise and not low temperature. How can it be that these chips still work without dying like it happened with for example the 8800? Because better solder, better chip design etc. These are BGA chips. The AMD's run even hotter. They still run after years of use. What you state is pure ********. It has NOTHING to do with BGA. Educate yourself in this matter. Posts like this keep the myths alive. Only selective products died on a massive scale because of bad solder and bad chip design and it had nothing to do with BGA. Thermals over 90C could kill a chip premature though if the other factors are poor as well.But it happens on the inside way before the heat does its work on the BGA mount itself. -
Now, consider this:
Why is if I heat a 6990M or RSX without liquid flux, I get pretty much weak/no improvement and immediate failure after light usage, but if I use liquid flux and drip it under the BGA package, I get a much longer fix (permanent in most my cases). Nothing to do with BGA right? Sure, ok...whatever you say. Putting pressure on the die to apply pressure on the BGA balls to make proper contact aka penny trick has nothing to do with BGA, right? ok....
The presure needed to fix the solder internally under the die itself would be too much, crack the die.Last edited: May 18, 2016dzedi likes this. -
Oh and the incorrect information about the rMBP? I just didnt name the Nvidia GPU's but that doesnt mean that there werent any AMD laptops with the same issues and that was my point. -
You were faulting AMD in the rMBP for an issue that doesn't even exist (yet...) with their chips. -
If my "beloved" Alienware lasts as long as my previous Vaio's then I have nothing to complain. My old Vaio Z1 from 2011 is still rocking on in someone else's posession and has been overclocked, heavily gamed on etc. It was a Nvidia 330 an even older vaio with a Geforce 8400 is also still working fine and I have tons of other machines that still work. Just as most graphic cards keep working even though they are all BGA. -
It's very unscientific, but putting an old, almost gone, chip with lead balls grants extended use, unlike using lead-free solder where it might not even turn on afterwards. I think that it has a lot to do with flexibility. We are talking about microns here, but they are enough to crack paths/balls/you-name-it. Lead solder is more flexible and allows for reduced stress/bending on the chip. After all there are A TON of things to be taken into account - the chip itself doesn't heat-up equally, because of different placement of components on it (shaders, cache and etc); the board has different flex characteristics, that's why directly soldered chips have better chances to fail especially using lead-free solder; and pretty much everything that heats/expands/bends differently and is around the about to fail chip. Every little difference helps to put more stress on the solder and eventually crack. Again that's very unscientific and is my take on the matter.

@rinneh and I will always have our differences (inherent characteristic of the internet), but let's try and get this topic back on track. Aside from the rebrands, there is no info about the Polaris mobiles yet is there?
Mr Najsman and triturbo like this. -
No new info as far as I know, my opinion about this topic is on the first page and I think that we actually improved it later on
@rinneh - That's why I said that using lead balls further reduces the stress and even almost gone chip can outlive a new machine with bad design, because you are limiting or removing entirely that bending. As @Raidriar mentioned that's the reason why oven backing can only be used that much times, at second or third time there wont be anything to melt and/or to help the process of melting and bonding i.e. flux (yes I'm talking about the flip chip as well, if it goes no amount of lead balls and flux (on the interposer) can get it back, you'll need a new chip). There's also the thing that lead-free soldering happens at higher temps, that puts even more stress to the components and there are a few variations of the lead-free solder depending on the elements used and of course since there are variations, the quality varies as well.
