To know what the GPU is drawing, we really need three numbers. That one both with and without GPU folding plus the power draw with the GPU removed.

To get the latter value, you'd need to remove the GPU, reconfigure to use your IGPU, then switch back. If you do that, any GPU WU you have downloaded will be discarded. :(

Idle power usage of RX 480 was measured e.g. by "Tom's Hardware" and is around 16 watts.
When we add this to folding watts difference 115 watts this is 131 watts total.

The card pulls 75 watts from power supply plug so this leaves 131w-75w = 56w to pull from pcie slot.
Looks like for folding the gpu is below the 75 watts pcie slot spec.

I have removed the card at the moment. GPU-Z stated 107W from readings sensors, folding stock. GPU-Z reading on GPU load was 100%. But at early stage this will be inaccurate. Anyhow my wattmeter is always tuned and tell the truth.

115W reading was done when the slot folding RX480 paused and unpaused after. 530W total folding 980 ti (5930k OC 4,5Ghz on water) and RX480 in same rigg, 405W when folding was paused on RX 480. Then I will guess 115W (even when GPU-Z stated 107W).

Is there any more updates to how the 480 is performing now it's been out a few days. The custom coolers from board patters should be out soon also rumors of a nvidia 1060 are circulating on the web

What do you want to know?

This pic shows 310k PPD - http://i.imgur.com/iaSlN9Q.jpg

I was about 300k - 350k PPD on my system when folding on stock.

With more cooling and some undervolting and overclocking you could get GPU to 1300Mhz and VRAM to 2100 without using more watts. This is an increase of 10% performance. This is what board partners will do soon. So the average PPD would increase from 325k to 350k.

But better wait for new driver anouncement which fix potential pcie slot over watts.

PPD results

Postby GentleGiant » Tue Jul 05, 2016 4:47 am

I just got an RX 480, and on Windows 10, with Radeon Crimson driver 16.6.2(?)(whatever the initial release driver was) I see 270-300K points per day. This is on projects 9643 and 11402.

It runs continuously at the 1266Mhz boost clock, and a temperature of 78-81C.

Interesting power result if it's drawing only 110w~ and is preforming the same as a 980 which I am presuming draws more power any one know the power draw for a 980 for f@h

Yeah, about the same as a stock 980 which in my experience are around 160-170 W when folding.

Definitely better PPD / Watt but given the 980 is previous gen on 28 nm, I would hope so! The interesting comparison will be with a new smaller die pascal chip...

Rumor has it and from suspected leaks the 1060 will be somewhere between the 970 and 980 in performance estimated tdp of 120w which will be quite interesting as we could see sub 100w for around 250-300k ppd but im not expecting the 1060 to be same price as the 480 I'll guess there will be a £50~ increase for the basic 3g nvidia 1060 over the 480 then again nvidia could shock us all for once and release a semi affordable card considing the 1070 and 1080 prices

If definitely won't be right at release. The 1080/1070s are well above MSRP still. Unless they have a lot of cut down die to use in the 1060 would it hit its expected price targets quickly.

Some more competition would be nice from AMD.

You are wrong, it is more like 970. One 970 ends up about 310K PPD.

This thread is about AMD products, so keep it to that topic please. Feel free to start a new topic if you want to do comparisons between AMD and NV. Thanks.

OK will do since some pics of a sapphire nitro have been seen and the change to 8pin and 175w tdp looking forward to what the card is really capable of since initial rumors of this card being able to hit 1.5-1.6ghz would see a fair increase in f@h performance and to see what the power draw is with the changes

The new AMD driver 16.7.1 is now available which fixes too much power draw over mainboard pcie slot.
