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.. -_-

Techpowerup lost a lot of my respect when doing their Crossfire testing they used Hitman in DX11, and Rise of the Tomb Raider in DX12.

ROTTR has excellent DX11 CFX support, and none in DX12, so they completely skewed their results by doing that. Not to mention that DX12 is slower for all regardless in ROTTR.

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

This isn't a new development.

AMD has been overvolting every single product line for the past few years be it CPUs or GPUs or whatever, on SOI and bulk processes, different architectures. It's across the line on every product they make.


You'd think all the fancy power management slides on Polaris and other products would amount to get this problem solved, yet we get results like computerbase's. They'll have to eventually get this solved because the average user isn't going to be installing afterburner or using wattman to dial voltage down and stress test to find the perfect spot, reap the savings and get the product as it more or less should be from the start.


Either the rumor of power management not enabled on RX480 is true when we get RX470 and see the 2.8x efficency number shown on the slides (RX480 isn't hitting that number), or the power management features are enabled and this is the best it can do to get voltage down to the sweet spot.

Perhaps this might be interesting. As you see, a 65 delta in measured power. I guess techalter would be around the Hardocp reading.

From 53W [Hardocp] less than a GTX970 system to 12W more [guru3d]. A 65W measurement spread for a 150W card is HUGE and can't be explained away with traditional reasons.

hardwarecanucks get 24W less
techreport gets 2W more
anandtech gets 12 less
Hardocp gets 53W less
computerbase.de gets 26W less

all of the above use total system power

techpowerup gets 7W more
Toms gets 7W less
guru3d gets 12W more

these do card power

I haven't had time to thoroughly review any one review, I've just seen the bench numbers.

Why are the results all over the place for this card?

As always, looks like you have to avoid AMD launches and wait for things to settle down.

It's because a lot of sites test against custom 970s, which aren't all the same. Overclock3D for example test it against a Zotac 970 Amp Extreme, which is faster than a stock 980 and uses a lot more power.

so reference amd gpus go up against custom nv AIBs in reviews, while reference and custom AIB gpus goes up against reference amd gpus?

that is some stacked odds.

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 ofthe 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.

Or retail boards could be even worse. AMD has apparently been stockpiling retail boards for some time. If they are markedly better or more consistent, why not get them into the hands of reviewers?

AMD RX 480 (1350mhz) vs GTX 970 (1500mhz) Review | Benchmark Showdown

RX 480 OC wins in 8 out of 13 games; and completely smokes the GTX970 OC in all DX12 games in the review. GTX970 is basically DOA now since it has less VRAM, non-existent DX12 support/performance and has only 3.5GB of VRAM. Long-term performance-focused driver support for RX 480 vs. GTX970 should also be a no contest.

Joker noted that the card could NOT maintain 1266mhz boost out of the box in games at stock Power Limit settings. This is very disappointing since it means RX 480 reference is a repeat of R9 290 reference but for a different reason = reduced GPU clocks due to the power cap (instead of temperature thermal throttling). It's pretty shocking how AMD aimed to have an HD7850/7870 Pitcairn linearge successor but the reference card draws close to 170W. They better shift Vega to TSMC.

The best advice is the same as has been for many generations: just skip the horrid reference blower GTX1070/1080/RX 480 cards in favour of AIB versions, unless you will be manually undervolting and/or putting waterblocks/AIO on them.

The AIB RX 480 should fix almost all of the key issues related to the RX 480 reference card, aside from the mediocre perf/watt. We could potentially see a 8-10% increase in performance from AIB cards knowing that a reference RX 480 actually GPU clock throttles. This is actually a big deal since that could be enough to get an AIB RX 480 close to GTX980.

Sweclockers Summary Charts




It's shocking what a pile of garbage the GTX780Ti has become against Hawaii (83% vs. 100% R9 390X at 1440p).

Sweclockers 1315mhz overclocking vs. stock results 100% prove that a reference RX 480 never maintains 1266mhz boost clocks in games.

We have a 1315mhz/supposed 1266mhz Boost => 3.9% GPU clock speed increase but the performance increase is nowhere close to that.

12% faster with OC


10% faster


10% faster


12% faster


10% faster


12.5% faster


100% confirmed by Sweclockers = out of the box, the RX 480 reference cannot maintain the 1266mhz GPU boost without a Power Limit adjustment (and most likely a more aggressive fan profile).



This is R9 290 Reference Repeat 2.0. How could you not learn from that launch? Now even if AIB cards are 8-10% faster, the launch reviews are the first impression.

On the positive side, it means stay as FAR away as possible from the reference card and wait for the AIB Sapphire Nitro, MSI Gaming, Asus Strix.

Perfect is a goal you strive for. It is not something you typically achieve. Holding off for a perfect launch is a great way to never actually launch. There will be hiccups, always. To suggest that "AMD should have went for a perfect launch" as if that's a tangible goal for any organization, as if that's something you can just do, is incredibly naive.

Well then how about almost perfect. Its very important for them to strive for at least almost and NOT launch with a freaking bandwidth limitation bug. That would be a pretty big, GLARING, thing to correct before sending samples out for review.

I have to say though, power consumprion and possible bandwidth glitch aside, 480 has great performance for its price. Gouging aside as well. Not AMDs fault.

All power managements are not enabled on the 480X according to Hardware.fr.

That said AMD s way of doing things guarantee that there should be less than 2% variation in perfs from a card to another since all cards works at the same frequency +-10MHz.

if 480 AIB can equal or beat 980 performance, it will become a 240$ mid range card, no longer a mainstream part. it will become king under 300$

This is what I'm looking for basically. Good stuff now I hope some of the third parties will pull through with decent coolers and a nice overclock. Not like I enjoy overclocking too much yet if the custom models come with some sort of boost it will be nice. Now I just hope they release soon and that I'll be able to grab one.

I think you're reacting as many in assigning a cause without any clear investigative thinking.

The tested results show a 65W spread of power on a 150W card against a 970 powered otherwise identical system. Do we get this spread normally with a new card release? I don't think OC 970 models are the reason here. The new power saving tech in Polaris are 3 different systems [adaptive clocking, AVFS and BTC] and they have to interact and complement each other in complex ways. I can easily see this as one of the reasons for the spread.

Although I only have 3 samples from sites that do card power measurements, they appear to be higher than the sites that measure the total system power. Could this indicate that BTC [Boot time power supply calibration] is getting screwed on boot in these cases and making wrong adjustments?

I don't know, but everyone is choosing their favourite explanation and saying that's what happening.

Empirical evidence trumps theory every time. Something new and strange is happening with Polaris. Solvable with bios, driver????

The Hardware Unboxed reviews have tons of data, he did crossfire as well:

vs 390:



vs 970



vs 380 / 960 (old ~$200 cards)



Price/perf:


http://www.hardwareunboxed.com/amd-radeon-rx-480-benchmark-review-23-games-tested-three-resolutions/


Crossfire scaling:


Surprised at the low ROTTR scaling, 390 was almost 100% scaling, might need a driver update for that.

2x 480 vs 1070:


2x 480 vs 1080:

The proper comparison will also be the cheaper RX 480 4GB card. Sooner or later AIBs will have rebates. By October 2016 (roughly 2 years after 980 launched), we should have ~980 level of performance for $200-220. Just goes to show what a waste of $ most high-end cards are. That's why the idea of buying a $550-700 card to future proof for 4-5 years is illogical in this new era of bifurcated GPU generations.

Are you living under a rock? This behavior was discussed several times already. Computerbase.de tested 20+ games for 20 minutes and found that for all games frequency throttling sets in due exceeding power target (not temperature target). Then the increased the power target and achieved 1266MHz for all games. (see first table on page 5 of their review).
On top of this, they ran all their benchmarks with and without increased power target.

-The 970 SSC was running stock clocks (1340MHz, not the 1500MHz you put up).
-The RX480 edges out the 970 SSC only when it is overclocked to 1350MHz.
-With the RX480 at stock speeds, the 970 SSC wins in all games, but that is expected given its reference vs aftermarket.

The RX480 doesn't really smoke the 970. It barely edges it. His results falls in line with most reviews out there: both cards perform similarly.

I am not sure why you call the 970 DOA when it's been available on shelves for the past 2 years and is about to go EOL soon. You are comparing the 970 to a brand new architecture that came out 2 years later and benefits from a full node shrink. And yet, it barely edges its predecessor in performance and efficiency. The only thing it has going is its price/performance, and that is because that's the only thing AMD can do when they cant compete elsewhere. Doesn't look promising if this trend continues for Vega.

Vulkan may be more GCN favorable than DX-12.



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.
Of course GimpWurse is fair and neutral... get in with the program, or no more cookies.

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.

Are there any more reviews that check undervolting? I'd like to see power consumption in more GPU intensive games.

apologies if ive missed it - but from a forward thinking perspective, how many games being tested have leveraged Dx12/ Vulkan?

in all this noise, im wondering if the true strength of the cards hasnt actually been touched yet?
