AMD RX 480 Fails PCI-E Specification


Hmmm... Who to believe. PCPer and Toms who have done testing with specialised equipment. Or a Youtube shill who constantly makes pro AMD videos...

Anyway, an update from PCPer:

UPDATE (7/1/16): I have added a third page to this story that looks at the power consumption and power draw of the ASUS GeForce GTX 960 Strix card. This card was pointed out by many readers on our site and on reddit as having the same problem as the Radeon RX 480. As it turns out...not so much. Check it out!

@ AdoredTV

If your reading this, thanks 'yet again' for bringing some intelligence into the debate :)

PCPer have already torpedoed his uninformed claims. In addition a MB vendor they reached out to stated that the continuous high power draw over the PEG slot would cause failures in some boards.

I asked around our friends in the motherboard business for some feedback on this issue - is it something that users should be concerned about or are modern day motherboards built to handle this type of variance? One vendor told me directly that while spikes as high as 95 watts of power draw through the PCIE connection are tolerated without issue, sustained power draw at that kind of level would likely cause damage. The pins and connectors are the most likely failure points - he didn’t seem concerned about the traces on the board as they had enough copper in the power plane to withstand the current.

Let me know if Youtube shill does his own testing, or just desperately flails around trying to discredit others informed working.

PCPer have their view he has his, the people who tested the board and approved it for public use also have theirs.

To me AdoredTV talk a lot more sense that PCPer and Toms Hardware.

Thats ignoring Toms Hardware result on the 950 Strix are completely different to PCPer's.

I would be shocked otherwise. :)

Can you link us up to where he does his own testing to counter the PCPer and Toms results, I'd very much like to see them.

Errmmm did you watch the video???

I don't get the hate for this vid

He only uses information that is out out there, makes no assumptions outside of this is a storm in a tea cup that should blow over and uses good sources for his conclusions... Mostly Tom's.

Exactly as I see it

Until people start coming forward with genuine power/MB/PSU issues relating to the 480, then it a storm in a tea cup.

Unfortunately it seems he doesn't completely understand what he is seeing. He should have read the PCPer article a little more carefully:

One interesting note on our data compared to what Tom’s Hardware presents – we are using a second order low pass filter to smooth out the data to make it more readable and more indicative of how power draw is handled by the components on the PCB. Tom’s story reported “maximum” power draw at 300 watts for the RX 480 and while that is technically accurate, those figures represent instantaneous power draw. That is interesting data in some circumstances, and may actually indicate other potential issues with excessively noisy power circuitry, but to us, it makes more sense to sample data at a high rate (10 kHz) but to filter it and present it more readable way that better meshes with the continuous power delivery capabilities of the system.

Some gamers have expressed concern over that “maximum” power draw of 300 watts on the RX 480 that Tom’s Hardware reported. While that power measurement is technically accurate, it doesn’t represent the continuous power draw of the hardware. Instead, that measure is a result of a high frequency data acquisition system that may take a reading at the exact moment that a power phase on the card switches. Any DC switching power supply that is riding close to a certain power level is going to exceed that on the leading edges of phase switches for some minute amount of time. This is another reason why our low pass filter on power data can help represent real-world power consumption accurately. That doesn’t mean the spikes they measure are not a potential cause for concern, that’s just not what we are focused on with our testing.

It's a shame that AMD appear to have cut too many corners to hit a particular price point. The 480 should have been exactly what they needed right now, with Nvidia off chasing crazily priced cards right now, people are looking for something a little more affordable. This issue (real or not) is only going to harm the cards reputation.

They need to get AIB cards with 2x6 or 8pin connectors out as soon as possible. As well as (if they can) a software or BIOS fix that tells the card to use the 6pin if it needs to draw more power than the spec states. If they can get that done quick this should hopefully all blow over. (until the next time fanboys need forum ammunition :) )

RX 480 owners reported in AMD forum that the card damaged, killed or fried PCI Express slot.

Oh well guess we will see lots of damaged motherboards after reports filled on AMD forum.

God AMD fanbois are really sad. See how they treat him when he posts pictures of his case? Not everyone can have a super fancy case, and maybe, just maybe, there's something wrong with the RX480. It could be something else causing the issue, however they'll never even entertain the fact that it could be an AMD card causing the problem. Pathetic.
 
I was about to post the Pcper link but I realised it's already been shared.
It seems clear to me that this is definitely an issue that needs addressing, because the kind of people who are going to go for the 480 are going to be those who Don't have £100+ motherboards and 80+ gold PSUs, they're likely to be people with budget parts and this could very well prove to be something that screws them over down the line.
I also read that AMD forum post, genuinely disheartened that everyone is just trying to downplay it and make the OP look stupid. How can you take the mick out of someone's case when they're buying a budget gaming card?
 
If you want to see the potential problems a 480 can cause watch the latest video by science studio. He was building a cheap AMD build around a 480 and when he tested his computer would turn off at the same point during testing games. He swapped the PSU nd the VGA to identity the problem which was identified as the 480 with the motherboard he ws using.
