 Won't match up on a day-by-day basis with cryptobullions as the data isn't pulled at the same time, but long-term it matches up well enough, and it's good enough for "calculation" with.

 Most non-ETH altcoins are a lot less sensitive to memory latency issues than ETH and it's offshoots.

 GTX 1080 and 1080 Ti both work quite well and efficiently on ZEC, among other options.


 I doubt we are going to see much if any more hashrate out of the mining-specific cards vs their consumer varients - but dropping all the video circuitry and disabling the "video output" parts of the GPU die should result in substantial power savings, I could see 20-30% less power used at the same clocks as a result (which would be somewhat better than TheStilt managed on his "no undervolt" version of his R9 290 BIOS, but he didn't disable ALL the video capabilities and the video output stuff was still on the board).

 Pricing numbers seem to still be up in the air and conflicting - but IN THEORY these boards should be lower priced, though being smaller production numbers might limit the savings some.

 I did see mention somewhere that EVGA might be one of the "partners" after all - which gives me some hope for us "small fry" having access at a fairly reasonable price, given their direct sale policies.

 I suspect it's not too bad, given how old the GPU in the R9 39x cards are (same GPU as the R9 29x cards after all).

 For perspective, I think I was pulling 45-50 Mh/s ballpark on my "testing" GTX 1070 rig per card though.

 I strongly suspect that the R9 290(x)/390(x) are best off mining ETH or it's spinoffs at this time.

 Somewhere on the Nicehash website they list the urls and ports and such for their various pools.

 You can't mine ZEC specifically, though, you mine the algo and then their pool bounces your miners around where needed.

 I have run my A2 Scrypt farm that way at times in the past.


 I just did an interesting number estimate - ETH added about 30,000 GH/s of network hashrate over the last 3 months - that's a bit over 10 MILLION RX 480/580 cards (it's actually going to be more cards than that since there are a lot of RX 470/570 cards in there that don't do 30 Mh/s and not all that many 480/580 that do, though there probably are a few folks doing silly things like using a 1080 or 1080ti that can do a bit over, and likely a few of the Fury-based duo boards that do quite a bit over).

 3.3+ MILLION cards sold to miners each of the last 3 months just for ETH, as a probably conservative estimate.
 No WONDER the 570/580 are in short supply.

 As long as ETH profitability stays anywhere near it's current ballpark, AMD is going to be selling every card they can make at a significant markup to MSRP....


 For perspective, ZEC total network hashrate can be generated by something like *1* million GTX 1070, as I recall - and I suspect all non-ETH GPU-mineable cards combined might only need 2-3 million GPUs to cover their current network hashrate.

 Probably very similar to existing GTX 1060 6GB cards, but probably a little lower power usage.

 Given the card doesn't appear to actually be in production yet though (soon it appears), NOBODY KNOWS for sure quite yet.

 $224 seems a bit high though - you should try to talk them down to $200 at most especially given the quantity minimum.

(edit) well, now that 1060 consumer card pricing is going through the roof, perhaps you SHOULD grab them at $224.

$226 is a bit high, but the card SHOULD save 20-30% on power usage at the same clocks vs a consumer version.
It should also run COOLER - which implies it will likely last longer than a consumer card in mining usage.

 If they got it under $200 it would get significant attention from the mining community.


 That 1080 based card though is rumored to be aimed at the $350 range - given it would ALSO see significant power usage reduction and cooler running, THAT is going to get some interest *if* the price is close.



 I suspect they're going to be available to small folks, if only through certain "large" dealers buying them in bulk for resale.
 I could easily see ZoomHash selling them, for one example (and using a bunch more in their own farm(s) in WA).

 Lower cost and higher efficiency.

 I expect a "mining" GTX 1060 varient to use 20-30% less power than a non-mining varient at the same clocks, due to no video circuitry + disabling all of the non-mining-related parts of the GPU itself in the BIOS.

 Same reason a R9 290 with a BIOS from TheStilt runs a LOT cooler and lower power usage even if you DON'T use one of the undervolt varients, only more so.

 It also is apparently going to carry a MSRP about $50 lower, probably due largely to the removal of a lot of circuitry - but the postings from retailers I've seen claiming to have the card have all listed it as a somewhat inflated price.
 They need to get it under $200 to make it interesting.

 It should also run cooler at the same clocks.


 I suspect they will also change the BIOS to tighten up the memory timings somewhat (something else those TheStilt BIOS did) to increase hashrage, but the folks claiming 60 Mh/s out of the rumored 1080 varient are full of .... something. That GDDR 5x latency is STILL going to kill hashrate, they'll be lucky to get to 45 and I'd expect 35-40 at best.


 

 R9 280x with a good overclock (but not BIOS modded) can hit  somewhere close to 300 sol/s as I recall. Definitely over 250.

 I've had my pair doing other stuff for a while though, after the machine they were on decided to crash Win7 and corrupt the installation I decided it was time to move it to LINUX.

Scrypt is the realm of ASIC and has been for years - you need to reconfigure your miner software to use skein or groetsl (if either of those work on AMD hardware, you might need a different miner version).

 There is NO BLOODY WAY you were getting an actual 3+ Gh/s scrypt mining rate from any GPU, I'd estimate a R9 390X actual Scypt hashrate would be closer to 1 Mh/s (perhaps a little over).

"We don’t know yet how many CUDA cores are enabled, but since P104-100 is said to be paired with GDDR5X memory it may as well be GTX 1080. These cards are said to be more efficient than normal GeForce cards in cryptocurrency mining (~30 to ~10% depending on SKU)" - which extra efficiency is easy to account for, they probably disabled a lot or all of the video-specific circuitry via the BIOS or possibly on-chip (an OLD trick, refer to the modded R9 290 BIOS series TheStilt put out for mining back in Litecoin GPU days).

 I still think the P106-100 is badly aimed, but I do want to see that P104-100 have at least SOME availability to us "small fry".
 Too bad EVGA doesn't seem to be one of the involved "partners" (yet?)....

 That design makes no sense for a pure mining card.
  Looks more like a photoshopped effort - or perhaps a "pre-order" placeholder.

 A "mining" card, like the NVidia GP106-100, should have NO video connectors at all and the whole backplate should be set up to maximise airflow.
 On the other hand, AMD has this bad habit of needing a "dongle" for pure compute usage on non-workstation cards - but an HDMI port for that would make more sense as it's a lot smaller.


 There's been quite a bit of confirmation that the GP106-100 will happen - but it's up in the air as to if it's going to be available to "small folks" or only going to get sold to "major farms".
 I believe the consensus "official release" date for that one is June 19.

ZEC is reliant on a lot more than just the memory bandwidth, otherwise the GTX 1070 would NOT be quite a bit faster than the RX 480/580 8GB cards (that have the SAME bus width and memory speed).

ETH on the other hand is VERY reliant on memory bandwidth AND low memory latency, which is why the old R9 290 is still one of the best ETH miner cards in existence despite having rather low clocks on memory and core (but has a very WIDE memory interface) - and it's also why the HBM based cards don't do anywhere near as well as their memory bandwidth says they should, HBM has high latency compared to GDDR.

 I dunno where "stream processors" is from - even AMD doesn't use the Stream interface any more since they got in behind and started pushing OpenCL.
 Perhaps that was supposed to be "cores" or "shaders"?


 Process is not directly a factor, though it's a major INdirect factor that affects power efficiency and clock rates and how many cores you can fit on a chip without overheating.
 Pixel pipelines do not matter at all.
 Memory capacity does not matter at all (except for ETH and spinoffs that use a DAG file, as the entire DAG file has to fit into the ram on the GPU so you need "just enough" more doesn't help).

 I'm not going by "what I read on the internet" for pricing. I'm going by pricing QUOTED on cards that are "in stock" by major sellers like Newegg, Frys, Tiger Direct, Amazon - WHEN you can find any available at all.

 Yes, if you can find RX 470/480/570/580 cards at close to MSRP they'll hit ROI quick - but I think you underestimate Nvidia as well on ROI, do NOT assume "ETH" or even "ZEC" as the most profitable Nvidia options.

 Tradeoff on your 570s is the power useage - for someone with high power costs, the DOUBLE or more power used will eat a chunk of the extra gross income - and if you factor on a SYSTEM level, you're going to need 4 times as many systems which makes the cost comparison quite a bit closer (the 570s will still win on a $/sol basis but by quite a bit LESS than 2:1, while the power comparison gets worse).

 If you run the skein or groetsl coins, for most of the last month profitability has been 30-50% higher than ZEC has been for higher-end NVidia cards - and all of a sudden they're pulling in VERY close to the same gross income as your 4 x 570s are.

 Nicehash uses Claymore for ZEC, EBWF is faster than Claymore on recent versions - I grant it's not by a ton, but it does seem to be a 5-10% difference on the GTX 1070 and 1080 cards I've done my testing on at the same settings.

 I'm not going to go into *what* I'm running my NVidia farm on - but I will state that I made a LOT more on what I'm doing than I would have by running the farm on ZEC - ballpark estimate 50-70% range.
 However, that's in a situation that has a VERY small "total network hashrate" that HAS gone up noticeably over the last 2 months, so I'm not sure if the profitability will remain elevated over all other options for another month.
 I'll just say that the folks justifiably bragging about their skein-based coin profits last month didn't do quite as well as I did - even though they DID do quite a bit better than ZEC would have done them.

 Might have been true a month ago, but try finding ANY RX 470/480/570/580 for less than $500 or so TODAY.

 If you can find them at all.

 Per all the reports I've seen, the odds are looking good that the current "shortage" and resulting gouge pricing may last MONTHS on AMD RX 570/580 cards (and the 470/480 is out of production of course).

 To be fair though, $200 a month ago was kinda HIGH for a 300 sol/s RX 470 4GB - I paid more like $350 for my PAIR a few months back, though they were on sale at the time.

 750 sol/s seems low for a 1080 ti from the figures I've seen reported, unless you're running it at VERY high efficiency settings - at which point it's probably using 50-70% of the watts/sol of that RX 470.


 Can't just compare $/sol, watts/sol adds up over time too, especially if you run a rig more than a few months and DOUBLE especially if you don't have SUPER CHEAP POWER cost.

 HD 5750 is terrascale, not GCN - Claymore is written for GCN cards, though it *sometimes* works on some older pre-GCN cards there is no guarentee.

 However, I suspect part of your issue is you need more system RAM.

BURST and MAID both expect you to dedicate HD space to them - so they'd be competing, not "compatable".

 Same on STORJ - you can't use the same drive space for all three, though I suppose you could "split" a drive and run all 3 on separate parts of it.

 That won't be on anything close to stock settings.
 Stock would be more like 400-420 ballpark depending on your specific card (some have a FACTORY overclock).

I forget how I managed it, but I got a web-based wallet of some sort working, using a "local server".
 Might have been part of that "all in one" package and I do remember I had to go straight into the .bat file stuff to get it to work at all.

 IMO any program that depends on IE being on a system is STUPID and should be ignored.

More like NVidia wants to cash in on the cryptomining frenzy - but they don't seem to understand where they need to target.

 Interesting factoid, NVidia website seems to be down right now.....

 I have a few of the GTX 1070 gigabyte "ITX" cards - work reliably, don't clock as high as full-sized cards, but very helpful on heat management in 3-card non-riser rigs, and have had ZERO issues with them on a reliability basis.
