RX480 power useage vs nvidia...

Very ironic ... Undervolting the card increase performance...reduce heat and noise...I am not sure why AMD haven't done this in the first place...I don't see any disatvantage here actually...The efficiency overall made a decrease of 10-30watts ... It will be on par with 1060...

AMD Radeon RX 480 Undervolting Performance

By reading the above it seems that the card was rushed out and wasn't tested properly...
 
The more I read I honestly think it is the boot voltage test that is causing a higher base voltage then is needed.

Ya lots on reddit reporting same. I prefer this easy fix to any hard coding in a driver update. This issue was basically fixed already.

AMD probably just wanted to make sure all the cards can work out of the box. By lowering voltage you might find some cards have stability issues but so far it would seem to a be a rare occurrence.

Tuesday's fix will be for those who dont intent to use wattman. I hope if possible that they add options in wattman to manage GDDR5 power use separately vs gpu.
 
Overclocking almost always results in higher power usage what are you on about?

Do you mean the specs of the slot and or power cables? OC'ing always increases power usage.

I mean the power rating of a given connector regardless if it is the PCIe slot, 6-pin connector, 8-pin connector.

It is insane to do because you strive for a stable overclock (at least a logical person would).
Higher power usage is not the issue as that's what overclocking normally does. The power budget dictated by the slots, plugs etc is where you should stop at. If you exceed it you risk damaging your system components. More important you risk unstable power for an overclock. Why in the hell would anyone in their right mind introduce additional instability to an overclocking situation? There is no excuse.

I currently have a x79 system and my plan was to go with something like three 480 cards if DX12 took off 6-months from now. For now I'll keep the three Nvidia cards, along with my 12Gb SAS HBA. I probably should get a single GTX 1080 at this point. I'll evaluate everything six months from now. I am very disappointed in AMD.

I've read so many stupid comments on reddit etc it blows my mind. Many people still think you can pull 300 watt through the slot alone or say it's OK because the Asus 960 Strix has the same issue.
 
Yeah, the increase in performance mostly a reflection of the crappy reference cooler again? It ends up being heat limited, so lowering the voltage and heat produced makes the card run faster. With a decent heatsink on there this wouldn't have happened.

Maybe AMD purposely goes with a barely adequate heatsink to cut costs and makes it so their AIBs can easily top it? All the more reason not to buy one as a consumer though.
 
the cooler is fine for what is advertised on the box.

not sure what this issue is honestly.

Ya Tom's was speculating. Badly.

I hope he puts out some corrective info quick.
 
Dont know about you but I found Tom to be Nvidia biased for a while
and this is another great example...

The GTX 960 has huge power issues and no one cares...
 
New driver will fix this:

http://wccftech.com/amd-rx-480-power-update/

We promised an update today (July 5, 2016) following concerns around the Radeon™ RX 480 drawing excess current from the PCIe bus. Although we are confident that the levels of reported power draws by the Radeon RX 480 do not pose a risk of damage to motherboards or other PC components based on expected usage, we are serious about addressing this topic and allaying outstanding concerns. Towards that end, we assembled a worldwide team this past weekend to investigate and develop a driver update to improve the power draw. We’re pleased to report that this driver—Radeon Software 16.7.1—is now undergoing final testing and will be released to the public in the next 48 hours.

In this driver we’ve implemented a change to address power distribution on the Radeon RX 480 – this change will lower current drawn from the PCIe bus.
Separately, we’ve also included an option to reduce total power with minimal performance impact. Users will find this as the “compatibility” UI toggle in the Global Settings menu of Radeon Settings. This toggle is “off” by default.

Finally, we’ve implemented a collection of performance improvements for the Polaris architecture that yield performance uplifts in popular game titles of up to 3%. These optimizations are designed to improve the performance of the Radeon RX 480, and should substantially offset the performance impact for users who choose to activate the “compatibility” toggle.

AMD is committed to delivering high quality and high performance products, and we’ll continue to provide users with more control over their product’s performance and efficiency. We appreciate all the feedback so far, and we’ll continue to bring further performance and performance/W optimizations to the Radeon RX 480.
 
Tom's seems pretty fair when it comes to reviews, at least in the last few years. Although they suck the big one when doing APU reviews always using just DDR3 1600MHZ ram for the benchmarking tests. :):bleh:
 
I'm pretty sure Tom moved on from his hardware site like a decade ago. :bleh:

We still call it "Tom" just as we still call Anandtech "Anand".

Most of us are old enough to remember when they were all still at the sites which bear their names anyways. Except maybe for Kyle Bennett because that guy will never leave HardOCP ever.
