So the rumours have been out for a week or so but AMD is not feeding it. I think they still have something in the tank before the 7nm next year, so a Polaris 30 wouldn’t be bad.

RX 670 out this month and RX 680 the next... Or who knows?!

Don’t expect a big performance boost, will be using the GGDR5 with some additional CUs.

On Ethash,
< 40MH/s for the RX 680
< 35MH/s for the RX 670
That too if it can be harnessed by the modders.

Again, might just be the romour mill.

Wow, it could be out this weekend! (of course, it's still a rumor though)

AMD Radeon RX 670 rumoured for launch this weekend

https://hexus.net/tech/news/graphics/122966-amd-radeon-rx-670-rumoured-launch-weekend/

I'm expecting at least 45 MH/s on Ethash with RX 680 (as I've a feeling that AMD just might have optimized these for mining).

Amd fighting back the Nvidia ! Concurrence is good for us !

Others says that they will lock it for bios editing.
45MH/s never...

If they lock it for Bios editing they will lose a lot of customers, the miners. And since the miners are the majority of customers of AMD, they were never good enough to fight Nvidia in gaming , it can be a suicide move for them so I don't think they will lock the Bios editing feature found in the Polaris 20 cards.

This is good also for the competition as if these cards appear to be good for gaming too, Nvidia will be forced to lower their price for some of their cards. I don't expect these cards to be able to fight the RTX series because of GDDR5 limitation.

It is tempting to go over to the green-green side  :-\

There will be ways to go around a BIOS lock. People will consider hacking through locks if the risk of voiding your warranty/RMA (some have already enforced it) is nothing compared to the benefits you will reap. But like hell that’s gonna happen. If it’s locked, it stays locked, for majority at least.

I agree. It may be some time until a tool's developed to easily mod the cards to make them bios moddable, but it'll likely happen eventually even if the BIOs is locked. It'll be interesting to see the methods employed to lock the BIOS if AMD chooses to go through with locking the cards.

It'll also be interesting to see what the pricing for last-generation 500- and 400- series cards goes down to after the launch of the 600 cards. The last gen cards are already extremely cheap, with prices falling below $90 in some places, which aren't too bad of a choice if you have cheap enough electrical rates.

I have read they should release at or around 15th October.

wait not too long to see this card is hash faster like rumored or not

How can you expect that? they never said anything about changing the memory to gddr6 so forget that number. Maximum it will get is 38 and that with huge memory overclock and modified timings.

price is more important for these cards, it it is say $250 and bettee than a 1070 power use and hash rsat it would be the go too card

Why would you expect that? GDDR5 is good up to 9000-9500MHz and the change to GDDR6 would require a brand new memory controller and a large rewrite of the chip. Ethash is NOT core starved on the current cards - it's running as well as possible with the 256-bit bus without getting limited by the core. This is literally the limit of GDDR5.
The only thing we can safely expect is either a lower voltage for the same frequency, or a higher frequency for a given voltage. Which turns into better hash/watt ratio - small gains on memory-based algorithms like CryptoNight variants and Ethash, larger gains on core-based like X16R, lyra2z/lyra2v2, equihash.

I don't know how much I would trust these specs. We all know it was going to be 12nm, however looking at https://videocardz.com/ there are no leaks of any kind related to anything to the newer AMD GPUs.

I am sure if they were going to hit the stores soon they would of been leaked somewhere by now.

Either way, I don't see much demand for these GPUs. The ETH price is still low and in about a month there is going to be an issuance reduction. Many people already find it unprofitable, with the 33% loss of ETH block reward, many miners will be out of the game.

The demand is for gamers, miners seem to forget most gpus are bought for AI farms and gamers, mining is in normal years a tiny percentage of sales.  you can see from the  2080s and its tensor core they give a flying f about miners

amd need to focus at gamer after ETH reward change to 2  i think old  amd card is sell in used a lot.

ETH is not the only way to go for AMD, you know. The Polaris 20 is arguably most efficient on the Ethash algo like the Polaris 10 it succeeded. The Polaris 30 hopefully can be a tick, although that’s a bit of a stretch knowing that AMD has its eyes on the prize - 7nm.
Still if this current timeline and rumours substantiate, there might be space for a tock, around the time of the Vega 20. Improbable? Very likely so.

Gamers right now have a huge supply of any GPUs they can get.

If you guys looked at the eBay prices for the RX 470/570, they are selling for less than $100 prior to shipping.

Same with the Nvidia 1060/1070/1080/1080Ti huge discounts from MSRP.

I guess the gamers are finally happy after 1.5 years of not being able to buy a GPU at MSRP.

Doubt we'll see more than mid-30s on Eth, and as everybody has pointed out, that'll be irrelevant soon with reducing block reward (at least for huge swathes of the world due to power costs).

Gamers already have a huge range of last-gen cards at rock bottom prices, or better firepower in Vegas/1080tis, so not sure who these are aimed at TBH. If they're cheap enough maybe...

really?? waiting this cards for mining with ETH at lowest prices with a 11% drop today.??? are you fucking kidding???

You deserve to lose it all, omg.

There are some people who believe to in crypto so much that they are willing to mine at a loss too just to have enough crypto when the increase in the price will happen. I was one of these persons but I am not anymore as I have turned off my Rx 580 rigs which I manage for my friends and they agreed to do so. They will wait if any increase in price will happen in December and if not, they are willing to sell their rigs locally for 1500 EUR, which they have already got offers for them at this price.

I am only keeping turned on a rig with low power consumption cards like Nvidia Gtx 1050ti but that is just for hobby now as you don't make any money with them either.

OCTOMINER here. We work tightly together with a big AMD factory in China and we have received info that the RX 680 will only perform around 10-15% better than the RX580. Maximum 20% but currently it looks more like 10-15% increase in hashrate and efficiency. Also, around 10% retail price drop incoming for the RX 580 at the end of this month. We will post more here when I get more info and a sample in hand.  ;)

We will try to be one of the first to also offer OEM RX 680 GPUs bulk to our bigger customers with already modded BIOS loaded onto them.
Currently we buy RX 580's BULK directly from the factory with already modded BIOSes, the GPUs perform better than Sapphire Nitro RX580 out of the box. Our OEM RX 580 8G GPUs get 30.5MH/S at 128-130W power draw, we noticed our RX 580's are around 5-10W more efficient than BIOS modded MSI ARMOR RX580 8G. (this is real life power draw, the AMD GPU power measurements from software are not accurate).   ;D

From the reports so far, the 6xx series will be no more powerful than the 5 series cards, so dont expect any big hashrate increases. id say 10-15% gains are optimistic.

Yes, agreed. 15% should be on the high end, looks like 10% is more realistic. That's why also the RX580 will get a 10% price drop at the end of this month.

Is the RX 570/580 even in production anymore? I think the production ended months ago because the prices never really went down from over MSRP.

I think some stores have been increasing their prices to reduce their sales but increase their revenue and they were just hoarding them for the last few months, basically betting on another crypto rush and where they can get away with selling them for +50% MSRP.

I'm pretty sure the cards are now out of production or towards the end of the production process now with prices going as low as they are now secondhand and even new, and there doesn't seem to be another crypto mining rush on the horizon with the way crypto markets and the mining atmosphere is currently; I can't see AMD continuing to manufacture them anymore. Seems most stores are now lowering prices as demand lowers and revenue is going downwards too. The next price cuts likely won't be too big, but it's an interesting time for gamers and miners alike. GPUs haven't been at such a good price-to-performance ratio in quite some time.

RX580 and RX570 is still being mass produced at the moment,  I have seen it myself last week in the factory, there was a production run of 11K RX580 for Powercolor. Of course the quantities are less than some months ago due to the current market slump and decrease in mining profits.  RX680 core mass production has already started by AMD but the GPU factories in China have not yet started GPU mass production with them yet, they are making engineering and test runs. Mass production will start soon though.

Big mining operations still put in 10k+ GPU orders for RX580's. We know this because we sell them the GPUs with our OCTOMINER mining rigs and work directly together with a reputable AMD GPU factory in Shenzhen, China.   ;)

Now the wind’s blowing towards an RX 590.  ;D

RX 600 will be at 7nm

RX 590 will be at 12nm same hashrate less power.

Transition from 14 nm to 12 nm will not give a significant increase in performance and energy efficiency. Based on this, RX 590 doesn’t make much sense for mining. RX 600 should have a significant gain in hashrate, and saves energy, so they will be a good acquisition at a reasonable price.

The difference with RX590 will be like between RX400 and RX500 moreless.
So RX600 maybe next spring?

It seems likely that the RX 590 will feature the same GDDR5 memory as the 580 and the same memory speed as the 580 according to this Digital Trends (https://www.digitaltrends.com/computing/amd-rx-590-beat-1060-gb-3dmark/) article, with just a bump in core memory speed, so the card should have just a very minor bump in mining speed or basically the same hashrate as the 580 on memory intensive algorithms as some have said here. Can’t wait to see how the 600 series does in mining.

30.5Mh / s at 130w? This is to slow and consume to much. Every of my RX570 does 31 - 32 MH @ 0.85 voltage. This consumes less then 130w. I will measure one rig in the next days.

I think yours are moded individually. Theirs are mass produced, so not tuned to the best.

Hey. Thanks for the input but get an exact wall power reading and report here. Software power readings can't be trusted. RX570 @ 0.85 voltage, could actually mean that it pulls around 140-150W from the wall. Also, running it at 31-32 will not be good for long term usage, if you want to get a solid 2 years+ from your GPU. 30.5-31MH/S is the sweet spot that most big scale miners run their RX580s at.

have any news?

i saw only downgrade rx580 version.

Not yet, but I will be posting some news next week.
I just had a meeting in one of the AMD factories that we work with(finishing a 3000 GPU order for a client for OCTOMINER rigs) in Shenzhen and I can share some news next week about upcoming GPUs.  ;

https://octominer.com/wp-content/uploads/2018/10/OCTOMINER-AMD-GPUs.jpeg

i've got the same hashrate on vegas, but 670/680 should be cheaper

thanks for telling news.

This might only happenned if they will use as stock 2250MHz clock memory or GDDR6...
