SAPPHIRE Solutions will Support C32/Cuckatoo 32

[Sapphire_Ed]

After being the first to market with the SAPPHIRE RX 570 16GB HDMI Blockchain Graphics Card specially designed for the GRIN Community. SAPPHIRE is first again with the only Grin solution that will support Cuckatoo 32 protocol as a result of the recent update to the ePIC Boost Miner software and in preparation for Grin migrating to C32 in January 2020.

Updated ePIC Boost software drivers are now available to download here: https://gpuminer.sapphiretech.com/software/

Unnecessary hype, you trolls at sapphire should focus on increasing the rma to at least 6 years, nobody will buy gpus for mining anymore, return of investment right now is over 4400 days, that is almost 13 years.

Would be nice to see cards that are not fpga but built specifically for mining but has titan rtx or higher performance.

16 gb high memory bandwidth is good.
570 chipset is so outdated and slow on clocks.

[badbart]

Isn't ansd ASIC coming?  What are they thinking?

[Sapphire_Ed]

So a few replies...

Metroid: for GRIN COIN, the use of GPUs is the only source of mining right now and our 570 16GB card is the lowest cost card that can efficiently mine C31 for GRIN. So there are still some buying GPUs for mining.

Lunobird, I will pass your request along. The 570 is an older chip but a tried and true efficient miner.

Badbart, ASICs are still a ways out and even then might not be as cost effective, especially with the planned branch coming up that changes the mining to C32.

Thank you for the reply, please do keep in mind my suggestion, increasing the warrant would help in this market on selected gpus, aside from that, I know you guys can't do much other than what you are already doing, sincerely and to point it out, is a great initiative, Sapphire is not an Nvidia partner and as such the next amd's best thing is Navi and I think a plan on how to tackle the mining business with it is in progress. I do hope you guys as 1st amd partner can find ways to compete x nvidia cause the way things are, nvidia is winning and this market is only at the beginning as I sure think you at sapphire are well aware of it.

Radeon VII has 16GB of RAM, that should be the 1st choice for developing a GRIN mining soft

The reason we developed the 570 card was because it offers a more affordable solution for people to use. With a lower cost, lower power draw and that fact that the 470/570 has been overall one of the most efficient mining chips out this is a great product for those looking for a more cost effective solution.

[Iamtutut]

No, the price makes it totally uninteresting compared to the VII.

Once grin gets to ASICs, VII will still have well enough computing power for other cryptos (on cryptonight 1 variant 8 it's amost 3 times the 570 HR), 570 will get smashed by Navi.

That's not accurate.  My VII does 4.59 at 160 watts on Grin29.  Sounds to me to be more efficient.

[Grim]

hey sapphire-team, please tell amd to implement/port a rocm driver for windows ...

without ROCm driver support amd is becoming a no go for blockchain-tech fans using windows ...

blockchain-tech is ALL ABOUT decentralization therefore it MUST support as many systems as possible, otherwise this tech is useless if it remains a niche only.

and windows support is gladly or sadly very important for decentralization (as is of course linux and also apple os)

the 570 is probably still more affordable =P

I think your post is the not accurate one. He said it was ONE of the most efficient chips, not THE most efficient. He was speaking from an affordability standpoint.

Buying a Radeon VII for mining is incredibly stupid for a number of reasons...the primary one being the cost. Buying one at all really isnt a great idea since NVIDIA cards are better in almost all gaming aspects as well.


P.S. My 2 year old ALREADY paid for GTX 1070s run about 4.1-4.2gps @ 150w without being $700 in the hole per card.....

[lunobird]

0.47 GPS in Cuckatoo 31 @ 200 watts for rx570 16gb blockchain edition.  Price $400

1080 ti gets a tad over 1.0 gps at 150 watts.  Price $500-600 used

Sorry I'm not convinced yet on why the rx570 would be a better buy. 1080 ti and 2080 rtx smokes this in every way even if you had two of these rtx570 16gb cards.

[Sapphire_Ed]

Thanks everyone for the feedback. The 200 or so watts I mentioned is a single card total system load, not the card load, as some seem to have assumed.

[fanatic26_]

its still a 5 series card, they sure as heck dont draw 200w just because of a few extra memory chips

I am curious why grin31 is being targeted when that is the ASIC friendly version of the algo, Grin29 is meant for GPUs

Why put out a product targeting an algo its not meant for? I am a bit confused by that.

From the mimblewimble github:

Grin POW Basics

Grin accepts 2 Proofs-of-Work. Both are variants of a concept called 'Cuckoo Cycle'.

    CuckARoo (or ASIC Resistant) is intended to be mined by GPUs. It can be mined using a 6GB+ GPU.
    CuckAToo (or ASIC Targeted) is intended to be mined by ASICs in the future. It can also be mined using 11GB+ GPUs.



While yes with 11gb GPUs its possible, but that still not what it was designed for.


Edit: And how will you support C32? That requires a minimum of 22gb of VRAM for its graphing from what I understand.

Fwiw Metroid, this time you might be the troll.

Grin has been designed to support GPU with a phase-in of ASIC over the span of 2 years. I have several GPU's switched over to mining Grin and also one of the Sapphire cards.

ROI is 40 weeks or so as I running in in C31 which is the ASIC friendly algorithm. It's very ironic that a GPU is making money using the Grin ASIC branch.

Here's a breakdown of the algorithms and phased rewards. Yes it's in geek talk but these who understand will figure out how to make money.

Don't confuse age with ability. I have an old mustang what will destroy my 911 on the track (with some supercharger and suspension enhancements).

Grin mining for Cuckatoo31 or c31 on GPU's favors large frame buffers. It's been designed to run in 12 or 14 gb memory which is why the sapphire board trying to target. Otherwise you have deploy a memory paging or solver overflow routine which decreases fidelity (real life performance).

From what I've seen in the labs, the sapphire board outperforms the 1080ti mining C31 undermining pool conditions even though 1080ti reports 10% better performance.

Takes a long time to understand Grin as by design, it tries to address many of the deficiencies of today's cryptocurrencies.

To answer your question of why mine c31 on a gpu, it's very simple ... ARBITRAGE!  You point your GPU resources where it has the  highest leverage or the highest potential returns ... which is exactly what GPU miners do jumping from algo to algo or coin to coin.

c31 has 2 operating modes, mean (big memory for GPU) and lean (smaller memory for ASIC's). The return on c31 (basic-friendly algo) is much higher than on c29 (asic resistant algo) because of the network hash rate. I remember it was 15x more hashing power on c29 than on c31 meaning there is less competition on c31 and therefore higher rewards.

What is particularly interesting is that the returns on c31 increase about 1% a week and the returns on c29 fall 1% a week. My conclusion after doing the math is that c29 will be unprofitable soon whereas c31 becomes more profitable.

The other point to note is that all the grin return calculators seem to be incorrect as they do not model the return dynamics over time and are simply ports of existing calculations using todays static return.

Metroid, my apologies for the slight jab in my previous post.

I think it's great that Sapphire took the plunge to release a unique product for Grin while others are running away from GPU's.

Nvidia seems to be getting all the attention nowadays and it may get worse in ETH if and when they change to Progpow. I certainly hope that Navi puts AMD and Sapphire back in the race.
