why is antiminer s9 better than video cards?


what is a best?

Because S9 is a computer specifically made for bitcoin mining, it is highly efficient and has an enormous processing capacity (hashing) when compared to graphic cards.

You can still mine bitcoin with graphic cards but you'll need to spend a lot of more money to achive the same results as dedicated hardware.

Both.

S-9 will directly mine btc


Gpu can mine an Alt coin that you can trade for btc.

So if you have a s9. Mining btc directly



And a six card gpu mining eth the cashing to BTC

the gpu rig has been doing better the last month.

Many times the s9 does better

I do both. So it evens'out.

which graphic card is a best for a mining?

because it can mine efficiently bitcoin much better than any gpu, for example

one asic antmienr s9 is running at 14TH, the most powerful gpu only 1gh, you can see here that one single asic is 14,000 times more faster than a gpu, while consuming only 14x of a gpu

1000 times more efficient, for the best gpu right now 1070 nvidia and 470/480 amd are the best choice

AMD RX 470 4GB

?

That's pretty good for altcoin mining, I'd suggest AMD over Nvidia for this anyways since Nvidia cards just seem to have issues with a lot of mining softare

But do keep in mind you have to watch the thermals on the card just as you would for an ASIC miner. I've burnt two cards in the past  ;D

Which cards did you do that to? I haven't seen any modern cards that haven't come with some kind of automatic thermal shutdown.
Even if you're massively overclocked and overvolted a card, under no circumstances should it explode. Did you bring that up with the manufacturer?

thanks

what is it?

its a cheap and making more Than the miner s9

that is an x11 asic can mine dash coin and generate for you 0.015 per day while consuming 335 watt, the cost is the same as one anminer s9 but the revenue is higher

still bears in mind that altcoin are very unstable and while now dash is very high in value, this maybe will not be true in the future, while an s9 revenue is more stable due to bitcoin having a bigger and more solid marketcap

You can sell a GPU later for a reasonable price if mining is no longer profitable. ASIC don't resell well if they don't have ROI. That said if you have access to free power then I would suggest S9. just less hassle.

Summary:

GPU Mining: More options and many sites such as Nicehash where you can mine a coin with your GPUS and get paid in BTC
GPU's hold their value much longer than Asic's -- still have reasonable value 24-36 months later
Life of these miners is subjective because of many hardware factors but these you can repair yourself.

Asic's, Specifically SHA256 (bitcoin) miners are almost worthless after 24-36 months
SHA256 miners will typically pay for themselves in 12-18 months and earn you a little bit of coin over their initial cost.
Life of the miner is dependent on the costs of your power... got super cheap power? you can run it for years and make a profit.
Typically, you can not repair these miners yourself and will have to ship parts to China or order replacement parts from China in the event of a failure.

For me, I've made much more BTC using GPU's than I ever have with any Asic miners I own SHA256 and Scrypt

I never considered that, but it seems like you're right. People are still buying cards like the 7970 for mining (and general desktop use or gaming I suppose) and that's a 5 year old card. The only 5 year old ASIC I can think of is the Block Erupter USB which is practically worthless now, aside from a few collectors holding onto them.

this is a mistkae? 

X11 miner 450M PinIdea Dr2

 Video cards went through a major period of stagnation during a large part of the AltCoin era - the 7970 vs the R9 280x was the same core GPU chip with slightly faster memory and a BIOS update, then the R9 380x repeated the concept vs the R9 280x, for example - the hashrate and efficiency however was almost identical between the "3 generations" because the core GPU was the SAME CHIP.

 This happened because the applicable video cards were all built on the same process node (28nm) that was semiconductor state-of-the-art for several years (Intel's 22nm process turned out to be a VERY MINOR improvement at best over a good 28nm process, which is why almost nobody outside of Intel and RAM makers ever adopted it).

 The only MAJOR change that happened during the 28nm generation was AMD's creation of HBM memory, and the resulting Fury line of cards.


 Bitcoin mining hardware, on the other hand, has had short generations for a long time while they were catching up to the current "state of the semiconductor art" - the Antminer S5 and SP 20/30/31/etc generation was the FIRST Bitcoin miner generation built on the then-current process node, which is why it was the longest-lasting generation up to that point - they had to wait for the 14/16nm process to get mature enough and AVAILABLE enough to start designing miner chips on the new node.

 The current generation of ASIC-based mining gear for Bitcoin (and now for LiteCoin/Scrypt coins as well) should have a 3-5 year run at the top, as the S9/T9/Bitfury/Avalon/etc. chips are at the "state of the art" - this doesn't mean there can't be SMALL improvements in the near future as TSMC and GlobalFounderies "tweek" their 14/16nm processes for small improvements, but it DOES mean the days of large rapid mining gear generations are OVER for SHA256 and Scrypt (X11 still has some room to go there, as I'm pretty sure the Baikal is on a 28nm process node while the other 2 X11 ASIC-based miner groups were on older nodes yet).

now i want bay amd RX 780 and i can make every mounth 45$
what are you thinking about this card?

There is no such thing as an AMD RX 780.

Perhaps you are thinking of the NVidia GTX 780, which is a 2 generation old high-end NVidia card that *might* be viable for mining some coins but I don't know enough about to say if it's profitable to do so.

 Perhaps you're thinking of the RX 480 (current, can easily make $75+ gross income (before electric cost) at current ETH or ZEC conditions and possibly more with some BIOS mods and tweeking)?

 There is also supposed to be a minor upgrade called the RX 580 showing up next month, should sell for a small premium over the current RX480 initially but only offers ballpark 5% better performance via usage of a slightly enhanced version of the same process the RX 480 uses.

 I don't have any RX 480 myself, but they're widely used in mining rigs for ETH ZEC XMR and offshoots of those coins like ETC - they MIGHT be the most commonly used GPU in cryptocoin mining at this time.

 I have had a couple of the "little brother" RX 470s mining away for a few months now, mostly have been on ZEC with some time on ETH depending on relative profitability.

I don't think you're going to have much luck mining with Nvidia cards.

I believe AMD cards have some bit rotating instructions which don't exist on Nvidia cards (have to be implemented as multiple instructions, maybe 3 or 4) which slows a lot of crypto applications down on Nvidia cards.
Additionally AMD cards seem to have a lower additional cost which makes it easier to buy a bunch of them.

How hot were you letting them get?

i have a one question

for example i bay amd RX 470-480 graphic card

now price is a 200$


i needed 5 Month for The amount of extract

Is it worth buying?

and how thinking can risk?

Antminer ASICs - no, they do one thing only.

GPUs - definitely, they are PC hardware.

Although Antminers are Asics- Application Specific Integrated Circuit boards and they do mine only one kind of algorithm since S9 does the king Bitcoin it will behave well until S15 comes out which I believe will do soon or maybe is already out as I have seen pre orders on Ebay.

Gpu rigs though have more elasticity they can mine different algorithms and at certain times maybe better than Asics so it all depends on your point of view which suits you better. Both makes you crypto being the same end result.

S15/T15 was released a week or two back on the Bitmain website.
Like the S9, they can ONLY work on the SHA256 algorithm, so much less flexable than a GPU-based rig but HUGELY more capable on SHA256.

Note that miner import fees still exist for miners if you're importing miners from Bitmain (or any company shipping from China) to the United States, and that fee is currently set at 25% plus 2.6% which comes to a total of 27.6% for those trying to get miners in the US. This is something you need to add into any potential calculations of break-even time if you live in the US, and it's making mining via ASICs a bit less attractive here.

There's a discussion about this in the BTC Mining section (click to go the thread) (https://bitcointalk.org/index.php?topic=5028276.0) if you're looking for more info for this. Shouldn't be an issue for people living elsewhere, but I know there are some people out there that are unaware that there are tariffs affecting ASICs from China as well.

In theory, the "trade war" truce should drop this back down to the previous 2.6%, but it's still up-in-the-air on when and somewhat iffy on if it will actually happen.

At this point though, given Jihan Wu's antics and the resulting COLLAPSE of Bitcoin (and almost all Altcoin) pricing and mining profitability, I wouldn't buy a Bitmain product if it was FREE and shipping was FREE.
LET HIM ROT.
