AMD et Nvidia innovent, le futur du minage Scrypt passe-t-il par les GPUs?
Guillaume Moulin 10/03/2014
For many years , AMD and Nvidia do battle on the front of PC graphics cards . But for two years , the terms of war have changed. The advent of the first software to undermine the Bitcoin via GPUs then the explosion of mining of currencies Scrypt algorithm caused unexpected Tub, including AMD , favorite minors.
The mining historically AMD

http://www.cryptocoinsnews.com/wp-content/uploads/2014/03/AMD_volcanic_islands.jpgAMD is the undisputed winner when talking about the mining of digital currencies and this is especially true since the advent of Litecoin and its algorithm based on Scrypt clones. The memory architecture of its graphics chips allows a speed of mining , or hahshrate , far higher flea Nvidia equivalent price .
Thus, if two cards medium ranges with a roughly equivalent price is opposed , the results in terms of hashrate on Scrypt currencies are unequivocal: Nvidia GTX 760 can reach a hashrate 140 to 160 per second as Kilohashs ATI offers R270X 420-470 Kilohashs per second three times being at the same time 15 % cheaper on average. The difference is even more enlightening on the top models .
A double-edged success for AMD
But what is a benefit for the miners quickly turned into puzzles for AMD . The company, located behind Nvidia in terms of sales for years, and had directed his plan of attack to regain leadership in the market for video games cards . However, because of the excellent results of its graphics cards for mining , miners around the world flocked to the HD 7000 and R9 models and have led countless shortages , particularly in North America and Australia. Consequence prices have exploded.

AMD cards were sold and up to twice their RRP . Today , the R9 290 Radeon card acclaimed by minors is 350 € in France , is not traded for less than $ 600 in the U.S. or € 436 .
The United States is by far the No. 1 market , both in terms of sales of gaming equipment or blasting in terms of digital currencies, the problem size for AMD , shared the excellent sales of its immediate cards and potentially devastating effects they could cause long-term , many gamers turning to Nvidia GPUs for their purchases . Because if the latest forms of AMD chips are competitive with their competitors Nvidia their recommended prices , this is not the case at all with prices increased by 40% to 100 %
This is one reason why AMD released this week a new model of graphics card : R9 280 , taken from the ancient model HD7950 , a former favorite of minors. Given descriptions published in the last days, we can still wonder about the AMD strategy that seems to have taken effective architecture of 7950 , with the only flaw in terms of mining , higher consumption . Stay tuned.
Reply with Nvidia Maxwell
The coming months should keep us in suspense . Both manufacturers seem about to deliver solutions that could be very interesting for the mining of crypto- currencies.

Nvidia chopping first with the first model of its new architecture Maxwell . The GTX 750 Ti Gefore has surprised the community by offering a performance far removed from those of his predecessors based on the Kepler architecture. It competes head- and AMD solutions in terms of pure hashrate . Thus the Nvidia card allows , according to preliminary tests Tom's Hardware and Forbes, to get about 280 per second Kilohashs version 2 Gb . Its competitor from AMD , the 260X R7 caps , according to Tom's Hardware to 206Khs/sec . The 40% gain in performance of mining is not offset by the higher price of about 20%.
In addition, it does not just return to the level in terms of pure speed. It differs widely in terms of consumption, given that a minor must look closely . So if the 260X requires 130W at full load , the 750 Ti simply ... 60 Watts .
Icing on the cake, the Nvidia solution heated much less (56 ° C according to the Forbes study ) and is very quiet , much more than its competitor .
A comparison of PC Perspective as well summarizes the performance of the newest Nvidia . While 260X capped a hash / watt ratio of 2.22 , the 750 Ti amounts to 4.38 and even 4.9 when overclocked .
Nvidia has made great strides in terms of memory and speed of its application to this kind of exercise . Furthermore the company has managed to do so while reducing the thermal footprint, fuel consumption and noise .
With the arrival in the weeks to come , the middle and high-end cards based on Maxwell architecture, Nvidia promises even more impressive energy performance . The Santa Clara firm therefore seems set to win handily the next round and the cards could steal the limelight from their competitors in terms of mining .
AMD and HBM technology
But within a few months, these efforts may be futile in light of recent statements AMD . The Californian company is thus associated with Hynix, one of the world leaders in the manufacture of semiconductors, to develop 3D memory modules for the next generation of its graphics chipsets series called "Pirate Islands" .
Hynix HBM comparison
Hynix promises to improve memory modules through HBM technology
This innovation is the stack of memory dies on top of each other and to connect with connectors through their silicon. Instead of reducing the space of memory modules on a single plane to allow faster access to information, it enlarges the contrary this space " 3D " which will increase throughput and storage volume, and therefore the bandwidth while significantly reducing energy consumption.
Without going into technical details , more than the promise of this new technology that let dreamer. AMD and Hynix and support the integration of HBM (High Bandwidth Memory) in the next-generation GPUs . This name, HBM , refers to a standard which should be operational in 2015 and compelled the modules at a speed of 128 GB / s where DDR5 currently used on the GPU maxes out at 28 GB / s. The stacking technology already exists , the challenge for both companies is to integrate a graphics chip solution , the latter being composed of more complex diseases .
In the end, Hynix promises improved by 65% while maintaining a significant decrease in consumption up to 40 % performance.
However, no date card availability has not yet been formalized by the two companies.
What face Scrypt for mining in 2014 ?
Finally, a question remains : what have the two historic rivals do ?
AMD understands that high performance mining could cause a potentially devastating perverse in his quest for leadership in the gaming. In contrast, Nvidia must envy the phenomenal sales of its competitor for several months , although its stockouts have also brought players into its fold .
With his future solution based on HBM , some observers think that AMD could share and offer both gaming solutions and ASICs oriented mining solutions. This could be a strategy for the California company , especially for publications it a few weeks ago , the technical specifications of the first projects for ASICs Scrypt currencies , having left the specs generally circumspect minors, if not doubtful . But to date , no report suggests this possibility.
Dedicated ASICs specialized companies , innovations from AMD and Nvidia, likely developments algorithms , the world of mining Scrypt will complicate the As of the year 2014.
While many miners were preparing to disconnect their graphics cards and think of new solutions , it is possible that the mining of currencies Scrypt by means techie goes on for many months.
It now should keep an eye to the outputs of different solutions to come to know what is the most effective way .

As an aside, and following the article before yesterday , it appears that the ultimatum Two-Bit Idiot was only the wind. The blogger has posted a new article in which he claims to have renounced publish his presentation announced today.
I wrote before yesterday :
Reading the words of TBI is difficult to imagine that the accusations could not be based on evidence .
I 'm probably wrong and , as he himself admits , TBI has in fact never intended to publish the elements he claims always hold . He also claims that the charges he brought are "100% true " .
Difficult to give any credence now blindly to these claims.
Mea culpa for this article I wrote thinking , in light of your offensive and resolutely determined by TBI employee , he could not possibly be trying to stir the wind. It was in fact the case .
