Bitcoin mining on a regular GPU is a factor of the past. Place basically: it’s no longer economically viable, given the energy consumption of discrete graphics cards and their relatively high price.
ASICs are a no-brainer when it comes to bitcoin, even so litecoin is a distinct story.
As opposed to its counterpart, litecoin can still be mined making use of off-the-shelf hardware, namely by way of AMD Radeon graphics cards. There are not that several alternatives, either. There are still no ASIC merchandise for Scrypt, litecoin’s algorithm, and this will not adjust for the next couple of months at least.
It is rumoured that litecoin ASIC systems are being developed by Alpha Technologies, but it will be a handful of months before they hit the market.
Additionally, Scrypt is a really different beast, as it needs a lot a lot more memory and distinct ASIC designs. This means that Scrypt ASICs could grow to be drastically far more high-priced than the existing ASIC-primarily based bitcoin mining options.
Are litecoin miners causing a Radeon shortage?
In any case, Radeons are currently the weapon selection for litecoin miners and earlier this week many tech websites reported that litecoin miners are causing a shortage of Radeon graphics cards.
While it is accurate that some cards in some markets are in quick provide, it is very hard to attribute this to litecoin miners with no any concrete information from AMD, its add-in-board (AIB) partners and distributors.
As a result, it is possibly hassle-free to make such claims, as they can not be easily disproven.
Litecoin mining is booming, that is a fact. More than the last month or so, the litecoin hash price has doubled, along with difficulty. It was virtually flat in September and October.
However, the rate currently stands at about 90GH/s, up from about 20GH/s in June.
Men and women are clearly purchasing Radeon cards and utilizing them to mine litecoin, but this isn’t necessarily making a shortage.
According to Jon Peddie Analysis, the discrete graphics card market is about 14.five million units per quarter, and AMD’s share is roughly 35%, so AMD partners sell about 5 million Radeon cards each quarter.
The numbers basically don’t add up, given the hash overall performance of AMD’s mid-variety and higher-end cards. In other words, litecoin miners are not even close to producing much of an influence on AMD’s general shipments.
There could be some isolated instances though, namely in the US, but it need to also be noted that AMD introduced new flagship graphics cards two months ago.
The firm also rebranded earlier generation cards and it is supplying a variety of game bundles to avoid inventory issues and transition to R9- and R7-series items, several of which are merely rebrands of older HD 7000 series cards. There are no Radeon shortages in Europe.
GPUs nonetheless have prospective for litecoin mining
Given that litecoin uses various hashing algorithms than bitcoin, with a lot more access to cache memory and memory in general, existing bitcoin ASICs do not tend to supply very good outcomes with litecoin.
Unlike SHA-256, Scrypt is memory-hungry and this was an intentional work on the component of litecoin developers to stop the use of ASIC and FPGA specialised hardware for litecoin mining.
FPGAs could be used, but at this point it isn’t clear whether the overall performance obtain would justify the added expense, specifically as difficulty and litecoin worth increases.
For the time being, Radeon cards are a reasonably very good choice for hobby litecoin mining. The largest difficulty is energy consumption.
A single Radeon R9 290X, based on AMD’s new Hawaii silicon, can draw up to 250W of power beneath load, but miners claim it is capable of around 860 KH/s to 900KH/s, based on the GPU clock and other variables. It expenses €499 in Europe, or $ 549 in the US.
Older cards, primarily based on the Tahiti core, can deliver even an even greater cost/performance ratio and the very same is accurate of the €399 R9 290.
The most well-known mining Radeons are the HD 7950, HD 7970 and R9 280, all of which are primarily based on the old Tahiti core and they are now regarded as mid-range goods.
FPGAs ought to supply superior performance per watt, but then once more they are not as readily accessible as graphics cards. In reality, litecoin distinct FPGAs and ASICs are nonetheless not available at all.
Furthermore, it is nevertheless unclear how significantly they will price as soon as they do appear, as hardware requirements for litecoin and bitcoin mining differ significantly.
Nonetheless, it is hard to speak about profitability at this point, since litecoin worth is going up, along with hash difficulty. Since the price tag is continually changing, it is up to individual miners to make a decision whether GPU-based platforms are viable in the extended run. At the moment, the answer is yes, but this could adjust in a matter of weeks.
Reusing old hardware is yet another option
A lot of bitcoin miners who employed GPUs are now stuck with old mining rigs, supplied they haven’t currently sold them.
Whilst it is feasible to argue that the spike in the litecoin hash rate was triggered by miners getting Radeons, it is just as possible that some veteran bitcoin miners have just located a new use for their old hardware, which has already paid for itself several times over.
It is highly unlikely that all of the miners sold their rigs and are now getting totally new ones to mine bitcoin.
Oddly enough, some hardware makers are attempting to money in. Final month, ASRock launched two motherboards, developed particularly for mining.
The business’s blurb focused on bitcoin, claiming that the boards could aid users “make a fortune.”
Needless to say, any person mining bitcoin with a regular x86 processor and a couple of Radeons on a inexpensive motherboard would only stand to obtain a whopping electricity bill.
Nevertheless, the motherboards could be intriguing for litecoin miners, as they are comparatively cheap and can take up to six graphics cards, though 5 of them will have to use PCIe 2. x1 slots.
So why are prices of Radeon cards going up specifically?
Litecoin mining is absolutely a issue, but it is also a short-term spike.
To steer clear of inventory issues, AMD and AMD AIBs don’t have a habit of stocking up, hence they are probably unable to cope with the sudden spike in demand.
Graphics cards are shipped in batches on a regular basis, not made overnight.
AMD orders the silicon from TSMC in Taiwan, PCBs and memory chips come from Taiwan, China and Korea, along with coolers, VRMs and other components, so creating positive the supply chain works effectively is a delicate balancing act.
For a lot of individuals willing to try litecoin mining, Radeons are the equivalent of a gold shovel in mid-19th century California.
AMD’s supply chain is not developed to cope with a sudden influx of new customers who do not care about upcoming games, custom cooled cards or other stuff that are important to gamers, AMD’s target audience.
Given that they really feel like they are promoting gold shovels, retailers and resellers are acting accordingly, by engaging in value gouging.
