Yeah, I have zero interest in it, and don't understand why anyone is interested in it.

I could maybe understand if it was more realistic, but it still looks like crap compared to reality, and that's going to be the case for a long time yet, as far as I can tell.

Even if it were realistic, I still have no interest in false reality.

And there's no way I am walking around my house with a thing on my head so I can watch CNN or porn or pretend I'm in the Civil War.

We already have people who can't pay attention to reality just from looking at their cell phones. They walk into things, crash their car, walk into you, etc.
They can't get along without their cell phones. If you take them away, they are like drug addicts without their fix.

I can't imagine what we'll get when people have the habit of wearing VR gear and being in a false reality for hours a day.

Well, to each his own.

wait until VR units become standard in self-driving cars--no longer will humans ever have to be concerned that they will encounter another human in public again. It's already difficult for too many people today.

Exactly. Now the spin begins. When everyone thought Polaris was going to equal or beat nVidia's new gen of gpus, performance/watt suddenly became the holy grail. Now we are back to the perennial AMD mantra "nobody cares about power consumption" from a lot of posters, although I will give credit to some AMD loyalists for calling them out on the lack of efficiency. And as usual, it doesnt help that both AMD and a lot of forum posters hyped endlessly about how efficient polaris would be. Unfortunately it wasnt *this* polaris.

Dont get me wrong, I think the 480 is a good value, and its relatively high power consumption would not automatically disqualify it for purchase to me, but it *is* a consideration, especially since I do in fact have a couple of computers with 400ish watt PSUs. If the 470 is in fact much more efficient than the 480, I might seriously consider that.

Raja said on Pcper that their focus was on the Polaris 11, the architecture was designed around it not Polaris 10. This is why your seeing the Rx 480 struggle in terms of power draw and frequency range.
RTG was built to make AMD focus on discreet graphics again, something that AMD didn't think well be profitable. Also he said Polaris is the first step to get back into the market and they know that that the competition is ahead atm. You should all go watch the interview it gives idea of what to expect from AMD in the future.

Polaris was touted to be extremely efficient at Computex. AMD bragged about it and under delivered once again. It barely matches Maxwell's efficiency when it comes 2 years later and benefits from a full node shrink.

That's a strangely declarative statement considering the piles of new info pointing towards wonky boards and drivers in the review sample, at least.

Other cards seem to be doing exactly what they were touted to do.

It's one thing to look at some poor initial results and criticize them justly--but ignoring all of the conflicting data and updated drivers and retail boards that may not be part of this sample is rather disingenuous.

Well even if that is the case why the hell did they send them out? If they can't even cherry pick cards for review samples the general public is screwed. Unless some of these are cherry picked and it's gonna get worse.

zinfamous makes a good point in that AMD drivers have historically caused underperformance upon a card's release. I'm willing to bet that, despite the RX480 only trading blows with a 970 today, it'll look better in a few years once AMD has had time to build proper drivers.

Not that this is really a plus.

If their focus was on Polaris 11, why were they talking about a 2.8X increase in efficiency when announcing the RX480 at Computex? Now we are lead to believe the 2.8X efficiency increase is for the RX470 or RX460. Where are those cards?

They had a few key events to convey the direction they want to take with their new products at Computex, and the PC gaming show at E3. Who is gonna sit down to watch some obscure interview about their future "true" plans?

AMD needs to fire their entire PR team, assuming they even have one.

someone earlier made a decent argument that from a business standpoint, it was a pretty smart move and I agree, because:

--If you can safely overvolt the bad chips and hit close to your relative performance target it is hardly going to matter to the market that is targeted for this card
--they've sold out inventory that was released at an estimated 20x rate than what is currently available for 1080--in about 2 days.
--It seems that AIB cards will be appearing within 1 or 2 weeks time with much better cooling, better drivers by then, and almost certainly better performance/power efficiency.
--the market that was holding out for those AIB cards is likely the market that actually cares about these details.
--It's also still very possible that the best chips were binned for Apple/Sony/Microsoft, probably even full chips that AMD hasn't even announced under Polaris yet? Dunno, that's purely speculation based on past history.

They hit price exactly as advertised with performance at that upper-mid to lower high range target as expected, with power efficiency well below that upper level and still a bit better than it's price point.

It really is still a win.

Where I think the real criticism and concern belongs is what this means for their process going forward--does it actually mean anything for future Polaris chips, Vega, Zen? is this 14nm FinFet "garbage" when it comes to power, is it a GloFo issue? There's a lot of ideas about this floating about and considering that some cards seem to be performing on all levels as they are expected to, while others certainly are not--it's just too early to say what the problem is.

This thing has only been out in retail for a day and over the previous couple of weeks in reviewer hands, I believe there were already 2 or 3 driver updates, and it was still known that they all had issues? Plus, when most of these cards sent to reviewers have a physical capacity of either 4 or 8gb and a BIOS feature to choose between the two, and a retail inventory that is limited only to 4 or 8gb on each card only, with no such BIOS feature, it further complicates what is going on.

I'm guessing we'll know a lot more after the weekend once all of the user stuff starts exploding.

Since we are already in the DX-12 era, with all major AAA games coming the next 6-8 months being DX-12 titles like Dues-Ex, Civilization VI, BattleField 1, WatchDogs 2 etc etc, why dont we ALL demand from Reviews to see how that perf/watt will be in those and the rest of the DX-12 games ?

One review measured the power consumption in Ashes Of The Singularity and it was 110W, how about Reviews measure the perf/watt in newer DX-12 titles like Warhammer and Hitman ?? Why nobody even benchmarked the one free DX-12 game available today ?? Forza Motorsport 6: Apex.

What new info are you referring to? I am not caught on the latest rumors, but the majority of reviews (including, TPU, PCper) mentioned that Polaris10's efficiency barely matches Maxwell's. The only other controversy I am aware of is about the power draw over the PCIE slot, but I doubt that would play a role in the card's efficiency.

Because it isn't "fair?"

:sneaky:

Honestly, though it makes sense I don't know we aren't seeing more of it. The games are there and while limited and the API is still a bit unknown (I'm assuming--is it?), it makes no sense for most of these sights to ignore the actual environment that these cards will be expected to perform in for the next 2+ years. And, this new architecture for the next ~5+ years.

I mean, there are conspiracy theories that one can discuss about this, or you can just look at 2 companies with 2 different strategies:

--One designs for the long haul and offers far longer support and optimization for their mainstream products for several years.
--The other designs for frequent turnover and a very short lifespan for their product. it doesn't matter if performance falls off a cliff and is soon bested by products less than half their cost 1 year later, because the new beast is now out in the market destroying everything else, and demanding a price premium that people seem willing to pay.

That's not a criticism. It's just an observation. I think DX12 isn't seen as completely relevant right now because it won't be all that relevant for another 6 months or so...at which point the market Godzilla will have dumped their current brand new toys for the next brand new toy.

I'd rather see benchmarks on a platform agnostic API like Vulkan. But that's why I prefer TPU's format of aggregating an average of games. Their methodology doesn't favor either team.

there has been a smattering of info, I believe, from AMD but mostly from other review sights about the the new Wattman/Crimson package not being well optimized. Some posted reviews also show wildly different power draws that are inconsistent with the gloomy ones.

Basically: there are a number of reviews that show poor efficiency just as there are a number of reviews that show things are quite fine. Either decide which ones to pick as "the truth," or accept that something else is going on. Just too many variables out there to make a conclusive statement about this being a real issue or not. Also consider that the majority of reviewers received different boards than what are available to retail.

And then there is this bizarre review:
https://techaltar.com/amd-rx-480-gpu-review/4/

take that with a grain of salt--seems like no one has heard of this place--but those power draws actually show better than expected and benchmarks that make this look like the greatest card ever.

....yeah. Who knows. lol.

check out the main review thread. It is wildly inconsistent in terms of performance. That tells me there is something of a chip/board lottery going on with at least what was available for reviewers (One would think that AMD would not send such boards out to reviewers knowing this was going on, so that is probably true to some degree for retail cards as well. Or it's just drivers and some combination of the both)

You do know that out of 16 games in the TPU reviews the last months, 10 games are NVIDIA GameWorks and only a single one is AMD Gaming Evolved (HITMAN) and that one is benchmarked in DX-11.

Only one review that contradicts dozens of other ones that are far more reputable? That's one anomaly I would attribute to testing methodology or credentials.

I hope it will clear out, but if it's another screw up from AMD, then you can just say that AMD never fails to disappoint with their botched launches.

that's the one one review that I linked because it was most recent on my mind.

There are others, but you need to go through the reviews. I ain't gonna do it and relink them here. There is an entire thread for it

There is some consistency in the power issue being an issue, but the degree of the issue is actually rather inconsistent. You're probably also dealing with different methods of measurement here, I dunno.

The takeaway is that it is both known that reviewers largely received physically different boards than those available for retail, drivers are new with a new uarchitecture and a new software suite. Too much inconsistency to confirm the degree of the problem, whether or not it actually is a problem, and how it can be fixed, if it can.

Even Kyle at [H], who apparently gets a chub for hating on AMD, reports sources that claim there is a board lottery going on. Some are great, some not-so-great. Regardless, it remains true that there isn't anything on the market that can beat 480 for $200 in any measurable variable, power efficiency or otherwise, and there won't be for some time. 1060 isn't going to be released less @ than $250, I imagine.

Also: it's been 2 days ffs.

Still hard to fathom, all this talk by AMD about their new power features and Wattman... and this happens:

https://www.computerbase.de/2016-06...el_potenzial_fuer_undervoltage_bei_der_rx_480

Just a simple under-volt in Wattman, they dropped power usage by 33W AND performance increased by 4.7%!

Instead of a 150W card that's behind a 390X, you now have a ~120W RX 480 that has 390X performance.

This is quite telling, because it's clear AMD's new power features are just not working as intended. It is not extracting peak optimal performance out of the chip at all.

This reminds me of the 7950 and 280 boost edition, where they just jacked up vcore to 1.25 default (earlier 7950 had 1 to 1.125 vcore) causing them to use a lot more power for nothing.

Yet another fail.

Vulkan favoring GCN is irrelevant. It is really easy to favor one brand over the other just by the selection of games to test.

AotS may favor AMD card, but is it a good game to bench to remain impartial? If you are picking it to counter balance games that favor NVIDIA, then you are just trying to skew the results towards AMD.

I am okay with the games TPU picks because they tend to represent popular games that can push graphics and that most people will buy or hear about. You can nitpick all you want about most of them being Gameworks titles, but what would be the point of including a title like AotS when only a handful of people bought it only for benchmark purposes? (last I checked, there were 149 players online, and the sp campaign is rather lacking). I rather have a selection of AAA titles that I will play regardless of which brand they favor.

Then blame AMD for not sponsoring more AAA titles.

But yes, they benching Hitman in DX11 is fail when DX12 runs faster for AMD GPUs. I see a lot of sites run RotTR DX12 when it runs slower for everyone.. -_-

I mean AMD likes to overvolt their chips and this is a chronic problem on them at this point, just look at Phenom IIs or FXes that could do stock clocks at -0.2 to -0.3v less depending on the particular model..

Now that's more like what's you'd expect from a 14nm class product. Why can't they get these kind of things right on launch? RX480's image could've been so much better at 120w for this segment vs the competition. You'd think they'd have gotten the factory overvolting "problem" under control after all these years and all those power management slides... What the hell.

I understand jacking up voltage across the board gets you better yields on otherwise mediocre silicon, but is it actually the reason they do this all the time or just piss poor binning to save money and guarantee functional dies?

It is well explained in the computerbase.de article. At standard voltage the GPU throttles in every game due to it hitting the power target.
Now you can do 2 things to ensure it is hitting 1266MHz in every game:
1) increase the power target (thats what they did when running benchmarks)
2) decrease voltage, such that the GPU stays below default power target for 1266MHz.

In any case, they just made the GPU stay at default boost clock of 1266MHz. Besides this behavior is very well known from R9 Nanos. You can make a FuryX out of your Nano by just increasing the power target and slightly increase boost clock.

Probably just lack of manpower/talent to design a better power management feature that does this automatically. Think NV's boost tech. Per voltage per clock dynamic.

Of course. Binning is out of question if you are offering a commodity product.
