AMD Polaris architecture – GCN 4.0

[humbug]

Who here bought that overclockers dream nonsense?

 

[SiDeards73]

Sid it's the provocative wording you use. It makes you look like an adolescent fanboi trying to start something.

dunno how else to express it Bug, AMD got smashed to bits by Nvidia, its been an ongoing assualt for a good while now, and AMD are just losing more and more market share, often to really schoolboy type errors

I was looking forward to it, although i did not believe it.

I agree with what you saying and a lot of it is down to AMD but at the same time the last thing I would want is for them to behave like Nvidia, no?

 

[Gregster]

I did. After eagerly watching the E3 PR piece and eagerly jumping on a Fury X at launch, I don't mind admitting that I was rather deflated with how it clocked and overall speeds. For the money I was expecting much better.

Joe Macri lied through his teeth in his claims of "Overclockers Dream"!!!

So now it is time to move on to Polaris, so far we know there have been two cards shown to the press and the power numbers for the smaller card, certainly look quite impressive, the before early September (back to school period), might be a little worrying, but of course that doesn't mean September, just sometime before that.

 

[humbug]

Isn't the back to school peddling for laptop's? They do tend to take much longer to arrive as the laptop needs to be designed and built around them, which means they are probably already sending them to manufactures.
What we are interested in here, descrete, is simpler are should be earlier.

AMD got smashed since Nvidia destroyed massively in laptops and OEM desktops since they took their eye of the ball and try to aim for the high end gaming and commercial markets. All that marketshare they gained with OEMs was wiped out. That's why the first part they previewed was the small part.

I think both nvidia and AMD were caught out by the lack of (a usable) 20nm process, and they went about the interim/stopgap cards in very different ways.

AMD banked everything on HBM, which came out late and v1 arguably has a latency issue that hurts them at 1080p (along with the limited architecture which is just Tonga on steroids.).

nvidia went and stripped out all the compute stuff they could get away with and made effectively the first pure gaming cards in several generations, and it worked extremely well.

I think you could argue that the Fury X is a better long term card than the 980Ti, as resolutions increase, DX12/Vulkan become the norm and VR comes along it should start to draw level and even overtake it quite nicely. However that doesn't matter at the high end, very few people buy a high end card and then keep it for 2+ years.

If HBM had been ready 6 months earlier then AMD would've been ahead of nvidia and forced them to release the 980Ti even earlier, which lets face it they forced them to release earlier than they would've liked (they could've milked the Titan X a good few months longer than they managed).

But Polaris, now AMD are showing working hardware and nvidia aren't even showing bare chips on a demo board, everything public right now points towards AMD having a healthy lead in getting some new cards out, but who knows what level they will be marketed at.

On the bold part, maxwell was out before the first news on 20nm scrapped came, so NV worked on them years before, not to counter the 20nm disaster.
While AMD had plans for the 20nm, and they were caught pants down, so they made what they can in the short time a new rev of the old cards.

The bloke who said "overclockers dream" was a high-ranking officer in the company who probably doesn't even own a desktop let alone a gaming rig. This is why you should stick to the script because trolls have managed to turn an ad-lib into a massive failing, just like HDMI 2.0. When in fact they hardly matter.

 

[CAT-THE-FIFTH]

Historically Nvidia has been better at getting the most out of older nodes and ATI/AMD have tended to jump quicker to a new node. This is why I think Nvidia was better prepared for the 20NM disaster.

If you look at Maxwell,they simplified the product stack and made almost all the cards cheaper to make than the equivalent Kepler ones.

 

[Orangey]

Maybe it takes more resources to do a purely architectural uplift to a new gen rather than relying on shrinks.

It isn't an overclockers dream and we get told time and again how nothing counts for factual till it comes from the horses mouth - IE someone from AMD or Nvidia and it wasn't. I paid well over £550 for a card that struggled with an extra 50Hz and whilst I really liked the AIO, sadly the statement made to everyone was a bare faced lie.

Edit:

The card is now gone, so I am passed caring but at the time I wasn't happy at all.

 

[thebennyboy]

Still quite happy with my 290X at the moment.

I probably won't bother upgrading until any of the games i play actually make it struggle, right now there is no such game.

Lot of things to consider.
normally what games and engines and then whats needed for compute and what the bottlenecks are. the GCN have lasted well and aged well over time.

It seems low end Polaris might be a <70w and that means no external connector needed. The redesign adds more for tesselation and whatever bottlenecks they adressing. we have HDR thats new and also VR and both requires different things.

For me Polaris seems to be a real step up and the die shrink is perfect timing.

 

[Davedree]

Fiji was probably designed for 20nm, the 20nm that didn't happen in the end so it had to be shoehorned into 28nm which it was never designed for.
They probably started work on Polaris as soon as they knew 20nm was not going to happen.

This time it looks like they might come good given they have a working Chip already thats 3 times the performance per watt of maxwell.

Humbug I respect your enthusiasm or your loyalty to Amd and sometimes you do bring great viewpoints. . I remember in the speculation ''390 before it was renamed fury thread'' you telling me I was way out in stating that a die shrink is needed far more for Amd than Nvidia if they simply scale up tonga , unless AMD can either rework gcn or create a new architecture.

You said they didn't need the die shrink they could get by rescaling like they did with Hawaii over Tahiti. It's quite funny that you now have changed your tune on this .

Don't remember that but fair coup to you, and sporting a GTX 970 some AMD loyalist I am

 

[tommybhoy]

I really really want AMD to pull it off, but if you get let down enough by something sooner or later you lose respect and trust.

This!

4870>5870>6970 CF>7970/50 CFX>7950 CF>290X they even gave us Mantle-'different gravy' and couldn't be happier, then went 290X CF and got 'mental gravy'-what's not to like?


Ramgate-AMD got 'X' of Nv's cash, free sales, how did AMD impress them?

The diver they installed, got uninstalled when they got fed up waiting for a new one and ran back to Nv.-Nv deliver!

FreeSync-FreeSync Monitors delivered, setup, 'why no FreeSync?' 'oh, panel makers released too early', yet they already knew the time frame involved exactly when their valuable high end customers that they can't use it.

AMD must have had many driver builds, perhaps a bugged intro driver was better than nothing?

FS mgpu-Don't get me started

More valued customers lost to Nv.-Nv deliver!

GW's- Masterstroke Nv pulled a blinder!

Most of the above=game over for this valuable AMD customer, sick to the back teeth of the let downs mainly because of mgpu GW's.

Amd release performance, the least said the better on GW's mgpu, FC4 iirc, ~4 months later mgpu arrived just in time for when I finished it using custom profiles with disabled settings

IMO-Yes the black box is at fault here, but when your running on AMD, they should have thrown bodies to get fixes out quicker-the buck stopped there!

So, sold up, and stop gap 970 bought in wait for Fiji, and lets see what Nv can do.

970 great card but so was the 290X.

Drivers-same/

GFE v Raptr-least said the better.

GW's, well it works on Maxwell, least said the better on Kepler

Fiji-no wonder greg punted it!

No chance I was going back to AMD on Fiji.

GW's titles-I've lost count, GE-Don't remember the one before SWBF, so what's the point?

Remember huddy talking why not use both api's?

Well, hate to break it to you AMD but Nv just slapped you again for the second time) and done it without so much as a peep like they did when he previously talked about 'freeworks'.

As I already ran FreeSync(which AMD deserve a lot of credit for matching Nv's vrr-as in the vrr, they perform exactly the same), and it was G-Sync here I come as you simply can't go back once experienced=lock in.

Did I say lock in?:

Spoiler

Needed a new tablet and couldn't say no for 140 notes could I?

AMD got smashed to bits by Nvidia, its been an ongoing assualt for a good while now, and AMD are just losing more and more market share, often to really schoolboy type errors

Nv's delivery/marketing/features/GW's(and AMD's all round incompetence) is destroying AMD to the point that Nv's main competitor is themselves, which is really sad to see, they need to get it together fast.

Sorry to any of the AMD users, while I've been blunt, it is what it is.

I'm not excusing the comment, but blown out of proportion, I mean Nv endorsed their high /ultra end mgpu dream overclocking laptops with a driver that disabled overclocking, that didn't even bat an eyelid did it?

Not quite right here.

My Fury X can manage a bigger overclock than my Kingpin GTX 980 Ti's.

The real problem for the Fury X is not the overclocking headroom but it's base performance compared to the GTX 980 Ti before overclocking is introduced.

The Fury X is actually one of the better overclocking cards you can get for example mine can go from 1050mhz stock to 1190mhz OC an increase of 140mhz or 13.3%.
