It has been a while since the Hardware Leaderboard has been updated as it is incredibly depressing to try to price out a new GPU, for obvious reasons.  TechSpot have taken an interesting approach to dealing with the crypto-blues, they have just benchmarked 44 older GPUs on current games to see how well they fare.  The cards range from the GTX 560 and HD7770 through to current model cards which are available to purchase used from sites such as eBay.  Buying a used card brings the price down to somewhat reasonable levels, though you do run the risk of getting a dead or dying card.  With interesting metrics such as price per frame, this is a great resource if you find yourself in desperate need of a GPU in the current market.  Check it out here.

Ripping out cryptocurrency with AMD's 1950X

Tagged: cryptocurrency, amd, Threadripper, 1950x

For the next little while at least, you should be able to pay off the purchase of a Threadripper 1950X by mining with it.  [H]ard|OCP did some testing using Monero and found that Threadripper is quite efficient at mining.  When mining full tilt the system, including a GTX 1080, used only 335W which could keep your energy bill somewhat lower than alternative systems.  Of course, with Bitcoin's value wobbling drunkenly might want to move quickly ... or skip it altogether.

"If you could have your AMD Ryzen Threadripper pay for itself over time, would you? No matter your feelings towards cryptocurrency mining, you can get your Threadripper mining today, and paying for itself. The process could not be much easier either. The big kicker is the actual wattage load on your system is likely much less than you would guess."

AMD Is Very Pleased To Participate in Blockchain Technology

AMD’s CEO Lisa Su was recently appeared on CNBC’s Power Lunch Exclusinve interview segment where she answered questions about bitcoin, blockchain technology, the tax reform bill, and sexual harassment in the workplace.

AMD CNBC.png

Of particular interest to PC Perspective readers, Dr. Lisa Su shared several interesting bits of information on cryptocurrency mining and how it is affecting the company’s graphics cards. Surprisingly, she stated that cryptocurrency miners were a "very small percentage" of sales and specifically that they represented a mid-single digit percentage of buyers (~4 to 6 percent). This number is hard to believe for me as I expected it to be significantly higher with the prices of graphics cards continuing to climb well above MSRP (it wasn’t too bad when writing our gift guide and shortly after but just as I was about to commit I looked and prices had shot back up again coinciding with a resurgence in mining popularity with the price of cryptocurrencies rising and improving ROI).

Further, the AMD president and CEO states that the company is interested in this market, but they are mainly waiting to see how businesses and industries adopt blockchain technologies. AMD is “very pleased to participate in blockchain” and believes it is a “very important foundational product”. Dr. Lisa Su did not seem very big on bitcoin specifically, but did seem interested in the underlying blockchain technologies and future cryptocurrencies.

Beyond bitcoin, altcoins, and the GPU mining craze, AMD believes that gaming is and continues to be a tremendous growth market for the company. AMD has reportedly launched 10 new product families and saw sizeable increases in sales on Amazon and Newegg versus last year with processor sales tripling and double digital percentage increases in graphics sales in 2017. AMD also managed to be in two of the three gaming towers in Best Buy for the holiday buying season.

Speaking for AMD Dr. Su also had a few other interesting bits of information to share. The interview is fairly short and worth watching. Thankfully Kyle over at HardOCP managed to record it and you can watch it here. If you aren't able to stream the video, PCGamer has transcribed most of the major statements.

What are your thoughts on the interview? Will we ever see GPU prices return to normal so I can upgrade, and do you agree with AMD’s assessment that miners are such a small percentage of their sales and not as much of an influencer in pricing as we thought (perhaps it’s a supply problem rather than a demand problem, or the comment was only taking their mining-specific cards into account?)?

Check that task manager every time you need a fresh cup of Java

It's an old story, web browser meets javascript, they head to a mine with your CPU in tow and they all decide they like it so much they pop under again and again without telling anyone.  There are many websites out there that use your CPU for alt-coin mining while you browse their site but a few have gone back to the old trick of the hidden pop under window to ensure you keep mining for them after you think you have closed their site.  The Register links to some more information on this practice, though not any of the guilty parties.  It is not hard to resolve this issue, just make sure you check task manager after closing a browser and terminate any remaining processes; a visual clue it is happening is that the browser still shows as active on your taskbar even though no windows will show when you click.

Today's shocking news; GPU vendors like the current mining trend

Subject: General Tech | October 19, 2017 - 01:26 PM |
Tagged: cryptocurrency, mining, gpu

At least some people are happy about the current GPU market and the effect cryptocurrency mining is having on it.  Indeed from the profit reports DigiTimes mentions, GPU vendors are making better profits from the current craze than the miners are, with all major vendors seeing major boosts to revenues.  This is good news for the average enthusiast as these vendors plan to ramp up their stocks and have greatly increased the amount of product they are ordering from NVIDIA and AMD.  It will take some time to fulfill these orders and you can expect the current memory shortage to have a minor effect on availability and price as well.  If supply can finally start to meet demand, we may soon see prices creep back towards MSRP.

"Gigabyte Technology and Micro-Star International (MSI), TUL, Colorful and Galaxy Microsystems have all been aggressive about the cryptocurrency opportunity since the mining trend emerged, and they have seen dramatic growths in related businesses. Asustek only started to see benefits from the segmnet in the third quarter."

Colorful Reveals Custom Eight Slot Motherboard For Cryptocurrency Miners

Subject: General Tech, Motherboards | September 14, 2017 - 02:13 AM |
Tagged: password cracking, mining, gpgpu, cryptocurrency, colorful, ai

Colorful recently unveiled an interesting bare-bones motherboard focused on cryptocurrency miners and other GPU heavy workloads with its main feature being eight double spaced PCI-E 3.0 x16 slots. The non-standard form factor Colorful C.B250A-BTC PLUS V20 motherboard measures 485mm x 195mm (approx. 19.1 x 7.7 inches) and offers a no-frills setup that is ready for miners to attach to open racks. The motherboard is based on Intel’s LGA 1151 socket and B250 chipset.

The majority of the board is taken up by eight PCI-E 3.0 x16 slots where the top slot is wired directly to the CPU and is electrically x16 while the rest are wired to the B250 chipset and are x1 slots. There are 16(!) PCI-E power connectors (eight 6-pin and eight 8-pin) for providing power to the GPU and two 4-pin ATX power connectors for powering the CPU and single SO-DIMM slot through what looks to be six power phases. Notably, there is no 24-pin power connector on this board to make it easier to use multiple power supplies and share motherboards between power supplies (though it’s not clear how Colorful plans to control turning all these power supplies on/off at the same time). Beyond the PCI-E slots there is not much to this motherboard. Internal I/O includes the 1151 socket for Skylake and Kaby Lake CPUs, a single DDR4 SO-DIMM slot, one SATA port, one M.2 slot, and six fan headers. Around back are two USB ports, one HDMI video output, and a single gigabit ethernet port.

The board is a no-frills design that should be quite appealing for miners but also as an easy way to jump into GPGPU projects (AI research, rendering, machine learning, password cracking, etc.). The 2-slot spacing allows air cooled (hopefully blower style) cards to be installed without needing to find and test quality PCI-E riser cables. There is no word on pricing yet, and while it should be on the cheaper side based on the features and hardware it’s packing as it’s a custom design aimed at mining it may actually come out at a hefty premium for the convenience it offers them. On the bright side, it might have decent resale value to factor into the ROI calculations for the other non-mining applications I mentioned (a mean password cracking rig!). A neat board in any case, and as I mentioned previously it is interesting to see the new designs and configurations the mining craze has enticed manufacturers into exploring.

Asus Launches B250 Expert Mining Motherboard With 19 PCI-E Slots

Subject: Motherboards | August 24, 2017 - 12:30 AM |
Tagged: mining, LGA 1151, Intel, cryptocurrency, b250, asus

Asus recently took the wraps off of a monster ATX form factor motherboard aimed squarely at crypto currency miners. The aptly named Asus B250 Expert Mining motherboard is based on Intel's B250 chipset and features an impressive 19 PCI-E slots! The board is based around Intel's budget chipset and is paired with an LGA 1151 socket for Intel Skylake or Kaby Lake CPUs. There are also two DDR4 memory slots and four SATA 6 Gbps ports.

Asus B250 mining motherboard with 19 PCI-E slots.jpg

The B250 Expert Mining motherboard is powered by a single 8-pin CPU power connector driving a 6-phase DIGI+ VRM, three (!) 24-pin ATX12V connectors, and three Molex power connectors. The top 24-pin drives the first seven PCI-E slots (including the single PCI-E x16 slot) while the other two 24-pin connectors are responsible for powering 6 of the remaining PCI-E x1 slots each.

Asus claims that the upcoming motherboard has several mining focused features including a tuned BIOS tweaked to improve mining efficiency, a splash screen at startup that shows the state of each PCI-E slot at-a-glance at each boot (Asus Mining Expert software) as well as voltage stabilization capacitors for each GPU slot.

With this motherboard miners will be able to hook up to 19 graphics cards to each motherboard which reduces the number of complete systems they need to build and maintain improving ROI time, increasing power efficiency, and reducing maintenance costs. At the time of writing there is a bit of hiccup with this plan though as miners will not be able to fully take advantage of all 19 slots for graphics cards. First off, miners will have to use Linux and even then they will be limited to a maximum of eight graphics cards from AMD and eight graphics cards from NVIDIA (if they can even get that working reliably...). Not all hope for an uber mining motherboard is lost though as Anandtech reports that AMD is working on a driver update slated for release later this year that will enable miners to use all 19 slots for their graphics cards.

Asus has not yet released pricing, but I would expect it to come at a hefty premium considering it offers the highest number of PCI-E slots on a standard motherboard so far. Asus has reportedly already begun sampling the B250 Expert Mining board to partners and it should be available at retail soon.

Even if you are not into the crypto currency mining scene, it is intriguing seeing the response to miners from the hardware manufacturers with new focused product lines.

Overview

There has been a lot of news lately about the release of Cryptocurrency-specific graphics cards from both NVIDIA and AMD add-in board partners. While we covered the currently cryptomining phenomenon in an earlier article, today we are taking a look at one of these cards geared towards miners.

IMG_4681.JPG

It's worth noting that I purchased this card myself from Newegg, and neither AMD or Sapphire are involved in this article. I saw this card pop up on Newegg a few days ago, and my curiosity got the best of me.

There has been a lot of speculation, and little official information from vendors about what these mining cards will actually entail.

From the outward appearance, it is virtually impossible to distinguish this "new" RX 470 from the previous Sapphire Nitro+ RX 470, besides the lack of additional display outputs beyond the DVI connection. Even the branding and labels on the card identify it as a Nitro+ RX 470.

In order to test the hashing rates of this GPU, we are using Claymore's Dual Miner Version 9.6 (mining Ethereum only) against a reference design RX 470, also from Sapphire.

IMG_4684.JPG

On the reference RX 470 out of the box, we hit rates of about 21.8 MH/s while mining Ethereum. 

Once we moved to the Sapphire mining card, we move up to at least 24 MH/s from the start.

Gamers Nexus Talks Mining with AIB and PSU Vendors

Tagged: supply shortage, shortage, ethereum, cryptocurrency

The cryptocurrency craze is kind-of like the old gold rush. Tokens are just out there waiting to be discovered, and value is applied when people trade it in exchange for goods and services. In this case, these tokens are discovered by doing math, and faster computers acquire more, and the algorithm is quite parallel. Some of the non-Bitcoin currencies are gaining traction, and becoming economically viable to mind with off-the-shelf parts, so gaming parts are being sold out... and not to gamers.

What do the video card add-in board (AIB) partners (as in the companies that take GPUs from NVIDIA and AMD and attach them to things that will actually plug into a motherboard) think of this? Gamers Nexus reached out to a bunch of them and, off the record, got a bunch of responses. The fifteen-minute video is quite interesting, and covers a lot of issues like brand loyalty, the second-hand market flooding, and RMA abuse. It even talks about the abnormal stress the GPU mining could have on power supplies. Most of the responses make sense, but it’s interesting to hear it coming from people in the industry, even if “who specifically said what” has been anonymized.

Of course, this is for the best, because you'll get more candid responses that way.

NVIDIA Partners Launching Mining Focused P106-100 and P104-100 Graphics Cards

Subject: Graphics Cards | June 26, 2017 - 11:29 PM |

In addion to the AMD-based mining graphics cards based on the RX 470 Polaris silicon that have appeared online, NVIDIA and its partners are launching cryptocurrency mining cards based on GP106 and GP104 GPUs. Devoid of any GeForce or GTX branding, these cost controlled cards focused on mining lack the usual array of display outputs and have much shorter warranties (rumors point at a 3 month warranty restriction imposed by NVIDIA). So far Asus, Colorful, EVGA, Inno3D, MSI, and Zotac "P106-100" cards based on GP106 (GTX 1060 equivalent) silicon have been spotted online with Manli and Palit reportedly also working on cards. Many of these manufacturers are also also planning "P104-100" cards based on GP104 or the GTX 1070 though much less information is available at the moment. Pricing is still up in the air but pre-orders are starting to pop up overseas so release dates and prices will hopefully become official soon.

ASUS GP106-100 MINER.jpg

These mining oriented cards appear to be equipped with heatsinks similar to their gaming oriented siblings, but have fans rated for 24/7 operation. Further, while the cards can be overclocked they are clocked out of the box at reference clock speeds and allegedly have bolstered power delivery hardware to keep the cards mining smoothly under 24/7 operation. The majority of cards from NVIDIA partners lack any display outputs (the Colorful card has a single DVI out) which helps a bit with ventilation by leaving both slots vented. These cards are intended to be run in headless system or with systems that also have graphics integrated into the CPU (miners not wanting to waste a PCI-E slot!).

  Base Clock Boost Clock Memory (Type) Pricing
ASUS MINING-P106-6G 1506 MHz 1708 MHz 6 GB (GDDR5) @ 8 GHz $226
Colorful P106-100 WK1/WK2 1506 MHz 1708 MHz 6GB (GDDR5) @ 8 GHz ?
EVGA GTX1060 6G P106 1506 MHz 1708 MHz 6GB (GDDR5) @ 8 GHz $284?
Inno3D P106-100 Compact 1506 Mhz 1708 MHz 6GB (GDDR5) @ 8 GHz ?
Inno3D P106-100 Twin 1506 MHz 1708 MHz 6GB (GDDR5) @ 8 GHz ?
MSI P106-100 MINER 1506 MHz 1708 MHz 6GB (GDDR5) @ 8 GHz $224
MSI P104-100 MINER TDB TBD 6GB (GDDR5X) @ ? ?
ZOTAC P106-100 1506 MHz 1708 MHz 6GB (GDDR5) @ 8 GHz ?

Looking at the Nicehash Profitability Calculator, the GTX 1060 and GTX 1070 are rated at 20.13 MH/s and 28.69 MH/s at DaggerHashimoto (Etherium) mining respectively with many users able to get a good bit higher hash rates with a bit of overclocking (and in the case of AMD undervolting to optimize power efficiency). NVIDIA cards tend to be good for other algorithms as well such as ZCash and Libry and Equihash (at least those were the majority of coins my 750 Ti mined likely due to it not having the memory to attempt ETH mining heh). The calculator estimates these GPUs at 0.00098942 BTC per day and 0.00145567 BTC per day respectivey. If difficulty and exchange rate were to remains constant that amounts to an income of $1197.95 per year for a GP106 and $1791.73 per year for a GP104 GPU and ROI in under 3 months. Of course cryptocurrency to USD exchange rates will not remain constant, there are transactions and mining fees, and mining difficulty will rise as more hardware is added to the network as miners so these estimated numbers will be lower in reality. Also, these numbers are before electricity, maintainence time, and failed hardware costs, but currently mining alt coins is still very much profitable using graphics cards.

AMD and NVIDIA (and their AIB partners) are hoping to get in on this action with cards binned and tuned for mining and at their rumored prices placing them cheaper than their gaming focused RX and GTX variants miners are sure to scoop these cards up in huge batches (some of the above cards are only availabe in large orders). Hopefully this will alleviate the strain on the gaming graphics card market and bring prices back down closer to their original MSRPs for gamers!
