AMD Radeon RX 480 May Not be That Great for Mining

Good find but poorly written article and provides nothing more than what has been speculated on the boards. No one knows for sure what the performance will be for ethereum mining. He literally took what has been said already, compiled into a blog and posted it. And he ended with the DAO issue and POS in a year.........

That is some deep journalism lol

i'm also more interested in the 470, there are great possibility with that gpu, it may consume only 25w in some case, if limited correctly, which is far beyond amazing

I saw it. Thr R9 470 might only consume 25W ? If so, I order twelve the day of the release. Do you imagine how wonderful it would be ?!

The 380x did 25mhs until the latest dag, now it's doing ~21mh so with the 14nm chips in the 480 should offer a jump in performance and efficiency, especially for claymore's dualminer.

whaaaat?!
do you got some real ethereum miner pics?
PS 380x of mine pushes 21.45mh/s @1500MHz gddr5 (elpida)

sapphire nitro oc r9 380x
now i can do 23.5mh/s @900/1625 (elpida-mod bios)

i cant see it using that little wattage even with bios mods, remember the 370 class cards are not voltage unlocked because they are budget cards , even some 380 cards are not voltage unlocked too although amd has already stated the 480 cards will be
voltage unlocked which should bring them to 100 watt or so.

I suspect without a voltage mod the 470 cards will do around 75watts from the wall maybe they can be tweaked to 50 with a bios mod.  25 watt is a fantasy, since the PIC power connector usually draws 25-75 watts itself on most cards.

We will see though.

The 380 will never slow down for the DAG change, those only affected the Pitcairn and Tahiti based cards, not Tonga.

I mean, I managed to do some bios optimizations with elpida gddr timings (hex workshop) and stock 21.5mh/s has been reverted to 23.5mh/s

The R9 470 only 25W? In my PC only my CPU (stock) consumes 50W. lol

25w may be far-stretched, but it's so out of reality to think that they might consume around 25-50w with the right voltage

[asdalani]

I will buy the 470 if the 256 bit memory bus is the bottle neck for the Ethereum mining. It seems it is still profitble to mine Eth.

[greaterninja]

Wow I tell everyone the CEO of AMD says the 470 will be 2.5x more efficient than the 370 and now everyone starts saying 25 watts?  LOL

But yes...AMD does sometimes fudge numbers.  Sometimes quite a bit more, sometimes less.


If the r7 370 is rated to use 150 watts, then then   470 should be rated ~60 watts according to the CEO's 2.5 efficiency claim.
However, my MSI 370 gamer OC cards use 125-130 watts on a gold power supply.
145 w overclocked.

I would say the 470 will most likely use  50 to 75 watts.

[Amph]

the nano can do 80w on ethereum with the right vmod, the same will be for the 470, with the right mod a lower wattage than 50 is more than possible, maybe not as a low as 25, but 30-40w is utterly possible

[Psynthax]

what kind of vmod? software mod via bios or hardware by soldering potentiometer ?

[greaterninja]

Either can most likely be used.

[Amph]

bios vmod, check the thread about the nano mod, it can really lower the wattege to a great extent, if a nano which is 28nm can be lowered to 80 watt which is like more thna 50% from the original tdp

i can't see why you can not do the same with a 470....

I agree with you. The 25 W is a big stretch. If I have the 470, I will run it at 75W to get the best peformance/watt ratio for the whole system.

[ethereumhunter]

Yeah let us wait and see until the product ready on markets and there are people who use the cards, we are talking without any proof.

[martorix]

Not sure if this is legit ~24Mh/s

[Psynthax]

not bad for 480.. now we need to find out how it behaves in other algos..

That result is as expected. that is due to the 256 bit memory bus. I think my R9 390 and Nano still have some lives.
