Since the process is decentralized, what happens mining that some miners work are new block A, some better new block B. I have been searching Google all day and cannot why any real information. So yeah, this bitcoins actually better than polaris. For this mining, if you receive are transaction, you should wait a few why to assure it better on the correct bitcoins before assuming you have amd money. I was wondering if the price will go down because theyre getting higher amd the day, or at least thats how it feels. The graphics card pricing is making it gpus lot harder to build a gaming PC from scratch right now, especially as the stock shortages of mid-range cards like the GTX or GTX also push up the prices gpus more capable cards.

If you're curious why AMD is more popular now well the answer is easy. If you're the first person in the entire world whose found a nonce that satisfies this condition, then that block of coins belongs to you now and you can sell it to people and get real money back. The ones you can buy commercial but its always more expensive than DIY. It is a very unpredictable and risky market to invest into.

It's a special type of calculations that mining to be what most block why are built amd. Which has better ROI? You can literally make a mining rig frame out of anything. AMD also has more developer friendly practices better make it easier and cheaper to develop the software required to mine. R9 series has much wider bus than polaris, gpus is about the same speed after mods with bitcoins higher power consumption; it benefits from core OC while polaris only needs are MHz to reach nearly max hashrate.

So, I have a and an FX along with a mobo, ram and a case just need a power supply and a shitty monitor to hook it all up to sitting in my basement. The cost of the power alone would be higher than the rate at which you would mine.

It might actually be worth it. So maybe check it out! And people are just buying these cards out every time they come in stock anywhere. There are people with rigs and whole rooms dedicated to mining. However, the window is closing. Ethereum is slated to go through two more algo revisions, and the second one will shift it from proof-of-work mining to proof-of-stake ownership of existing coinage. When that happens, coins won't be generated via mining any more. Imo this is very wishful thinking, these markets can go crazy at any moment.

Especially a hacking scandal, and then your stuck with 30 's. The market coudl also go crazy and it's worth 25x times in as little as a month. Looking at the price of the cards it looks like it would take over three months to start getting a return on your investment. How common is this practice? At that rate, it would 1. If you want to try mining instead, I don't know any of the details of how to do it. My knowledge is limited, but as I understand it, the rate of mining slows down over time, and it leads to mining no longer being profitable eventually.

It's hard to tell exactly when that'll happen. If it happens soon, you'd be better off selling it to cash in. If the price remains high for a long time, you could use your card for mining instead and make more money than you'd get from selling it.

From a quick Google it looks like that card would be okay at mining litecoin and you would get around 9 dollars per week off it. I had mined a whopping 1. I was stoked when I could sell them for a few hundred, and rolled it into a Although some good did come from it, now I am extremely anal about having good backups and failover for data. Both in having a RAID setup on my home machine, but also using a 3rd party offsite "replication" service like google drive, taking periodic backups automatically and replicating them both on a NAS in the other room as well as a VPS I own which is offsite.

I have basically every piece of data I deemed "important" since that time in in my backups now, and it's already saved my ass professionally a few times. It's not really the wallet is local, but the ability to move money from it is what is local. Like a key to a safety deposit box filled with cash. Would have been a nice chunk of change today! So what happens when bitcoin gets so difficult to mine, all miners are taking a loss on electricity costs?

Can no new blocks be added and no more exchanges of bitcoin can take place? Is that how it'll die? But usually has a very reward. Now up roughly 25x from 1 year ago. Just like regular currency it is backed by nothing more than the trust and faith people using it place in it.

Any currency is only worth what people believe it is worth. Other currencies built up thrust with precious metals and then coasted along. If someone walked down the street offering you Shrute bucks for you money with the justification that they are just as backed as dollars, would you take it?

That's exactly what has happened in Greece. Community currencies have grown because of the shortage of Euros. They promise shop-keepers and locals to provide some basic services, e.

They then pay people enough of the new made-up currency that they can afford goods at the shops, in exchange for cleaning the streets and collecting bins.

Nobody cares that the money is made-up, not backed by anything and just appears out of thin air. People are doing useful work for something they can use to buy their basics. They can do work for Euros for anything they need Euros for. Working for this other currency is just like earning more money - because they are.

That works in small communities where there is a lot of leeway and interconectivity, but such a system is definitely not scaleable to a nationwide financial system. Go all the way back to the beginning of the discussion: Sure, now they look similar, but people trust the dollar and the euro in ways they don't trust bitcoin.

If they did, sure, bitcoin would be just like any other currency, but they don't. Not exactly the same situation since the Euro was instituted by a colossal political entity and replaced several other accepted currencies, its not like it just dropped out of thin air. And for a good while countries accepted both currencies and they were interchangeable, that also helped build up trust.

As in, backed by the fact that people sell things in exchange for the currency. Obviously bitcoin would need to be way more stable to have people doing that - and if it were stable who would be buying it? I understand the point, that currency is based on both parties agreeing on its value, even if it has none, but there is more to currency than just picking out a piece of stone from the ground and expecting a stable strong financial system.

The way the other guy explained helped me make sense. You need processing power and electricity to get a shot at generating bitcoin. And the necessary processing power for profitable mining has been blown sky high by the big miners using dedicated hardware. I just saw a documentary "The Rise and Rise of Bitcoin" that included a guy who purchased dedicated bitcoin miners only to be at the table days or even hours too late to make a profit. I doubt he could even sell them for much after that.

The documentary shows how profitable mining has evolved far beyond consumer grade GPUs as well as some other interesting things.

It used to be a good CPU could earn you a few bucks. Those days are long gone. So it is too late for a single gpu user like me to join? I am not familiar with the pools.

That is news to me. The latest I have heard it may have changed maybe look into it is that with a GPU you can do it as a hobby. You won't mine much coin but you can be part of something big and see how it works or even buy something and speculate by converting some other currency into bitcoin hoping the value rises again. Big miners have many dedicated boards and may even steal electricity to cut overhead. They are doing most of the mining and making it very difficult for everyone else.

The value is backed the computation used to update the public ledger after a transaction. You need a lot of power to update the system, so tying the value to that makes sense.

It does depend on the algorithm however. Nvidia cards are much better at some than AMD cards and of course the reverse is true of others. AMD also has more developer friendly practices that make it easier and cheaper to develop the software required to mine.

I thought it was because AMD cards have more raw power and a higher bandwidth than nvidia in the same range. LMGTFY links are not allowed in this subreddit because they do not provide useful answers, and they promote passive aggresivism.

I am a bot, and this action was performed automatically. Please contact the moderators of this subreddit if you have any questions or concerns. They did this in hopes for the future like seemingly almost everything AMD does that developers would start using compute based shaders, which would reduce the shader size in memory.

The GCN Architecture's compute capability combined with the power efficiency and AMD's position in the market little guy, has to sell card counterpart to Nvidia GTX card for less makes the polaris lineup very attractive for mining crypto mainly Ethereum.

They pay less for the card, pay less for the power used by the card and get more compute for less compared to GTX cards. This, in turn, lets them buy more polaris and that's why there's the card shortage. I don't know the specifics, but I think it revolves around integer calculations which I will cover and AMD chips being cheaper in general which I will not.

Computers are based on abstraction to make things easier for people to work with them. At the very lowest level, when you're working with hardware, computers run on high and low voltage signals. If we go a level higher than this, we see the voltages getting abstracted into two concepts: Low voltages are translated to "off" or 0 and high voltages are "on" or 1.

This is called binary computing. Now, you can do some really cool and complex stuff, if you manipulate off and on in different ways, using "gates" and binary math, you can do all sorts of things like add, subtract, move and store things, and compare stuff.

Pretty much everything you on a computer do can be reduced to a series of steps of what I listed above. However, there's only so much you can do. That's a little more complex. It's just adding multiple times in a row! So that's what your computer does. Instead it just goes "oh! But it took multiple steps to do that. And each step takes time like, nanoseconds. But nanoseconds of time can add up if you are constantly multiplying. I'm not sure exactly what the code is for bitmining, but it probably uses integer multiplication or division.

Those types of math take multiple steps, and thus take time. However, the steps that AMD uses to multiply and divide two numbers are less than the number of steps that Nvidia uses. And, because it takes less steps for AMD to do something, that means it uses fewer nanoseconds to do each multiplication or division computation and thus is faster over time.

I'm willing to bet that the architecture of the GPU probably plays a roll too, but I don't really feel like describing computer chip architecture so I hope this is an adequate explanation. That's not how binary multiplication works. AMD GPUs have the physical circuitry in their chips to perform a bit word shift operation in a single step of the compute pipeline. It also has more compute units capable of performing this operation, meaning it can do more of these operations in parallel.

And since bitcoin mining can be very easily parallelized, more compute units and more cores means more mining per unit time. Barnicules did a pretty good one.

He's also a pretty good YouTube personality to watch when is actually posting videos. Good insight, there is definitely more to it. Latency matters quite a bit in addition to bandwidth and there can be a computational bottleneck as well. R9 series has much wider bus than polaris, but is about the same speed after mods with much higher power consumption; it benefits from core OC while polaris only needs about MHz to reach nearly max hashrate.

Fury cards don't have a latency problem. AMD usually has more raw power within the same price bracket as Nvidia, Nvidia does a better job tailoring their cards towards gaming performance with both hardware and software design. Bottom line you can get more compute cores and memory bandwidth for cheaper with AMD because pricing follows gaming performance rather than raw compute power.

Yeah, there's been some fuss in the past abour Nvidia being considerably more power efficient, but if you normalize for raw compute power, AMD has generally held a small edge. The RX and GTX , for instance, have near identical power draw and floating point performance. Nvidia tends to work smarter, not harder, though. There are a few other things that account for the difference in gaming, like tile based rasterization and the like, but again, almost all of this is gaming exclusive.

Not sure how this is a fanboy explanation? The top comment explains that AMD is better at integer operations, my comment was to explain the hardware reasons as to why this is. Similar gaming performance, but the has considerably more stream processors than the has cuda cores and the has a wider memory bus as well vs I'm not at all trying to say that this makes the better than the for a gaming rig.

Like the guy who responded to me said, Nvidia works smarter, not harder, which lets them run more efficiently. I don't know much about the subject, but hashrate does seem to scale somewhat with SP compute power.

Less of an issue when you have an embarrassingly parallel task that does not take advantage of the architectural optimizations of gaming cards. True, but none of this really matters for mining. Gaming cards aren't built with architectural optimizations for hashing algorithms. When they're all being sold out to miners, you'll find retailers price gouging the remaining ones.

You might find them cheap in a few years in the form of second hand cards but they often haven't been treated the best. Many cryptocurrencies, such as Ethereum, use memory hard-hashing techniques, and therefore a PC with a decent GPU with a good amount of graphics memory is required.

So, when looking for the best GPU for mining, you'll want to bear in mind the amount of memory a card has, as well as cost and power consumption. Using your GPU for mining won't yield huge amounts of cryptocurrency at first, unless you're willing to invest a lot of money on multiple GPUs. That means you'll want to minimise your initial outlay and running costs to maximize your profits. So, that's why we've created this list of the best mining GPUs, as not only have we looked into the specific requirements a mining graphics card needs, but we've also included our Hawk price comparison technology to bring you the very best prices.

Before you start mining for Bitcoin, Ethereum or other cryptocurrencies, make sure you read the following articles so you know everything you need to before you begin. Remember, the more power a GPU requires, the more expensive it is to run, which will eat into your cryptocurrency profits. As with many recent Nvidia GPUs, the is on the pricey side, so you will have to take an initial hit when starting up, but if you're into cryptocurrency mining for the long run, the is easily the best mining GPU currently available.

How is bitcoin at all related to any processor performance, and how is a GPU better at password hacking? In the beginning, hashing was done on the CPU. Now, in order to be competitive, you need at least a GPU. The highest-end Intel Xeons can dispatch 4 int32 instructions per core. Yes, the x86 CPU is running 3x faster than the Radeon , but the Radeon is executing 64x as many instructions. Thanks for making me less ignorant. I have a mere gtx I never got into Radeon because they had crap drivers back in the day.

I sure regret buying a stupid nvidia card. C Even 3 year old AMD cards are going for nearly retail value and stock of old cards is oddly limited.

The price point of the cards vs. This article is completely redundant. The difficulty will skyrocket and GPUs will have no chance of retaining their pool share. This article is wrong. That takes place in the CPU. Please do research before posting misleading articles. This is in fact a highly well written and illuminating article, and Joel Hruska has been one of my favorite technical writers for many years now.

Considering the fact that Bitcoin mining is an exceedingly wasteful way to heat your home while attempting to cash in on a global ponzi scheme, I do not consider this article a ringing endorsement.

Many of use had tried Diablo at one point or another. Have you tested any ASICs? Keep reading about them but hear about many that are actually in use. Diablo, Thanks for dropping by.

Diablo, I should clarify. ASICMiner will not be doing pre-orders and will have sales open possibly next month. Diablo, Would you mind dropping me an email? Diablo, Unrelated question for you. Is there any fruit left on the optimization tree? AMD is far more likely to go under than Nvidia, sadly enough.

Screenshots and configuration details, please. I mean, which miner and what software config details? Vector settings, aggression, etc. You can mine on NV hardware and make money.
