If you are a PC gaming and live near or around the Portland, OR area you are familiar with the concept of PDXLAN - one of the most popular (but still cool and underground) LAN events in the country.  The primary event is going on this weekend and I am here to both game and take a look at what the sponsors are showing off. 

pdx01.jpg

MSI has a lot of stuff going on including a look at the latest version of the Afterburner overclocking tool, the 3GB version of the GTX 580 Lightning (that Josh is currently working on a review of) and even a NVIDIA Surround based Dirt 3 sim seat.

pdx02.jpg

Gaming laptops are still taking off here in the US and MSI has a couple on display including a HUGE 18-in mode (on the right) with a keyboard that lights up with various colors of LEDs, configurable.  

pdx03.jpg

The Sapphire guys are here as well and are showing off much of what AMD for gamers including Eyefinity configurations like the very popular 5x1 portrait mode.  This is something that only AMD offers currently and in this demo we were looking at Dragon Age II.  It was definitely grabbing some attention!

pdx04.jpg

Showing that AMD's HD3D technology does indeed have legs Sapphire was showing off the new Samsung SyncMaster SA950 that has a nice external design.  I am going to spend some more time with it today to see how it performs, so check back for more!

pdx05.jpg

If you are here, you can also find me getting butt kicked at various games.  This is the machine I'll be on, a Maingear built GTX 580 SLI right with an overclocked Intel Core i7 Sandy Bridge processor and 30-in display.  I know, it sucks to be me, but someone has to sacrifice and play on it, right?

More from PDXLAN later today!

How much will these Bitcoin mining configurations cost you in power?

Earlier this week we looked at Bitcoin mining performance across a large range of GPUs but we had many requests for estimates on the cost of the power to drive them.  At the time we were much more interested in the performance of these configurations but now that we have that information and we started to look at the potential profitability of doing something like this, look at the actual real-world cost of running a mining machine 24 hours a day, 7 days a week became much more important. 

This led us to today's update where we will talk about the average cost of power, and thus the average cost of running our 16 different configurations, in 50 different locations across the United States.  We got our data from the U.S. Energy Information Administration website where they provide average retail prices on electricity divided up by state and by region.  For use today, we downloaded the latest XLS file (which has slightly more updated information than the website as of this writing) and started going to work with some simple math. 

Here is how your state matches up:

kwh-1.jpg

kwh-2.jpg

The first graph shows the rates in alphabetical order by state, the second graph in order from the most expensive to the least.  First thing we noticed: if you live in Hawaii, I hope you REALLY love the weather.  And maybe it's time to look into that whole solar panel thing, huh?  Because Hawaii was SO FAR out beyond our other data points, we are going to be leaving it out of our calculations and instead are going to ask residents and those curious to just basically double one of our groupings.

Keep reading to get the full rundown on how power costs will affect your mining operations, and why it may not make sense to mine AT ALL with NVIDIA graphics cards!

What is a Bitcoin?

This article looking at Bitcoins and the performance of various GPUs with mining them was really a big team effort at PC Perspective.  Props goes out to Tim Verry for doing the research on the process of mining and helping to explain what Bitcoins are all about.  Ken Addison did a great job doing through an alottment of graphics cards running our GUIMiner and getting the data you will see presented later.  Scott Michaud helped with some graphics and imagery and I'm the monkey that just puts it all together at the end.

** Update 7/13/11 **  We recently wrote another piece on the cost of the power to run our Bitcoin mining operations used in this performance article.  Based on the individual prices of electric in all 50 states of the US, we found that the cost of the power to run some cards exceeded the value of the Bitcoin currency based on today's exchange rates.  I would highly recommend you check out that story as well after giving this performance-based article a thorough reading.  ** End Update **

A new virtual currency called Bitcoin has been receiving a great deal of news fanfare, criticism and user adoption. The so called cryptographic currency uses strong encryption methods to eliminate the need for trust when buying and selling goods over the Internet in addition to a peer-to-peer distributed timestamp server that maintains a public record of every transaction to prevent double spending of the electronic currency. The aspect of Bitcoin that has caused the most criticism and recent large rise in growth lies in is its inherent ability to anonymize the real life identities of users (though the transactions themselves are public) and the ability to make money by supporting the Bitcoin network in verifying pending transactions through a process called “mining” respectively. Privacy, security, cutting out the middle man and making it easy for users to do small casual transactions without fees as well as the ability to be rewarded for helping to secure the network by mining are all selling points (pun intended) of the currency.

When dealing with a more traditional and physical local currency, there is a need to for both parties to trust the currency but not much need to trust each other as handing over cash is fairly straightforward. One does not need to trust the other person as much as if it were a check which could bounce. Once it has changed hands, the buyer can not go and spend that money elsewhere as it is physically gone. Transactions over the Internet; however, greatly reduce the convenience of that local currency, and due to the series of tubes’ inability to carry cash through the pipes, services like Paypal as well as credit cards and checks are likely to be used in its place. While these replacements are convenient, they also are much riskier than cash as fraudulent charge-backs and disputes are likely to occur, leaving the seller in a bad position. Due to this risk, sellers have to factor a certain percentage of expected fraud into their prices in addition to collecting as much personally identifiable information as possible. Bitcoin seeks to remedy these risks by bringing the convenience of a local currency to the virtual plane with irreversible transactions, a public record of all transactions, and the ability to trust strong cryptography instead of the need for trusting people.

paymentpal.jpg

There are a number of security measures inherent in the Bitcoin protocol that assist with these security goals. Foremost, bitcoin uses strong public and private key cryptography to secure coins to a user. Money is handled by a bitcoin wallet, which is a program such as the official bitcoin client that creates public/private key pairs that allow you to send and receive money. You are further able to generate new receiving addresses whenever you want within the client. The wallet.dat file is the record of all your key pairs and thus your bitcoins and contains 100 address/key pairs (though you are able to generate new ones beyond that). Then, to send money one only needs to sign the bitcoin with their private key and send it to the recipient’s public key. This creates a chain of transactions that are secured by these public and private key pairs from person to person. Unfortunately this cryptography alone is not able to prevent double spending, meaning that Person A could sign the bitcoin with his private key to Person B, but also could do the same to Person C and so on. This issue is where the peer-to-peer and distributed computing aspect of the bitcoin protocol come into play. By using a peer-to-peer distributed timestamp server, the bitcoin protocol creates a public record of every transaction that prevents double spending of bitcoins. Once the bitcoin has been signed to a public key (receiving address) with the user’s private key, and the network confirms this transaction the bitcoins can no longer be spent by Person A as the network has confirmed that the coin belongs to Person B now, and they are the only ones that can spend it using their private key.

Keep reading our article that details the theories behind Bitcoins as well as the performance of modern GPUs in mining them!  

As expected NVIDIA's next generation GPU release schedule was a bit optimistic

Subject: General Tech | July 8, 2011 - 09:37 AM |
Tagged: nvidia, amd, 28nm, kepler, maxwell

TSMC's 28nm wafer yields are having a negative effect on NVIDIA's scheduled release of their next generation of GPUs, no matter what the PR coming out of NVIDIA might suggest.  That news is coming from graphics card manufacturers who were hoping to release cards but have since seen NVIDIA's scheduled releases delayed by a year.  While it may be true that TSMC is partly to blame for the delay there is also talk about the chips performance being lower than was expected and is needed to challenge AMD.  The news for NVIDIA gets even worse as DigiTimes confirms that AMD is still on schedule with it's 28nm chips.  This may seem like a bit of deja vu, as we saw similar production problems from TSMC's initial 40nm chips; though that effected both major GPU makers more or less equally.

nvidia jensen.jpg

"Despite Nvidia CEO Huang Jen-hsun previously saying that the company is set to announce its new 28nm GPU architecture at the end of 2011 and 22/20nm in 2013, sources from graphics card makers have pointed out that Nvidia has already adjusted its roadmap and delayed 28nm Kepler and 22/20nm Maxwell to 2012 and 2014.

The sources believe that the delay is due to unsatisfactory yield rates of Taiwan Semiconductor Manufacturing Company's (TSMC) 28nm process as well as lower-than-expected performance of Kepler.

TSMC originally expected its 28nm capacity at Fab15 to be available in the fourth quarter of 2011 and was set to start pilot production for its 20nm process technology in the third quarter of 2012.

However, TSMC's other major client Qualcomm, currently, still has not yet adjusted its 28nm process schedule and is set to launch three new products, 8960. 8270 and 8260A using dual-core Krait architecture in the fourth quarter of 2011.

Meanwhile, AMD will follow its original schedule and enter the 28nm era in the first half of 2012. The company's next-generation graphics chips Southern Island as well as Krishna and Wichita processors, which will replace the existing Ontraio and Zacate processors, and will all adopt a 28nm process from TSMC."

Always someone to ruin the parade, NVIDIA's response to AMD's Southern Island news

Subject: General Tech | July 6, 2011 - 09:36 AM |
Tagged: southern islands, parade, nvidia, kepler, fermi, amd

As is common in the industry, when one company releases news their competitors have to do something to distract people.  Since in this case it was AMD's announcement of the Southern Islands release, it is NVIDIA who feels the need to hold a competing spectacle.  In this case it was news that their new Fermi based 28nm Kepler GPU has taped out ... maybe.  In this particular scenario we have an intentional leak from NVIDIA which was light on details and heavy on spin.  SemiAccurate takes a long look at some of NVIDIA's claims, from the doubling of transistors with no cost in TDP to the probable difference between Tesla branded Fermi and GeForce branded Fermi cards to NVIDIA's claims that switching from 40nm to 28nm is hard and that it is all TSMC's fault. 

CUDA_roadmap.jpg

"When SemiAccurate announced that AMD (NYSE:AMD) was aiming for September with Southern Islands (SI), you could almost set your watch to the Nvidia (NASDAQ:NVDA) response. If you are new to the PR game, you will probably scratch your head wondering what we mean by Nvidia response, officially there is silence, but there definitely was a response."

Badaboom, the once NVIDIA only transcoding accelerator, now works with Sandy Bridge

Subject: General Tech | June 28, 2011 - 08:34 AM |
Tagged: transcoding, quick sync video, nvidia, Intel, badaboom

When we first met Elemental Technologies Badaboom video transcoding accelerator it would only work with NVIDIA CPUs.  Ryan tested version 1.1 of the program, taking various movies and recorded TV and transcoding it into formats able to play on Blackberrys, iPhones, YouTube and a wide variety of other formats. 

slides01.jpg

The testing showed nice improvements when utilizing an NVIDA GPU and the ability to use multiple GPUs, each able to do their own transcoding simultaneously would help anyone who needed a couple of Blu-ray movies transferred to their mobile device in a hurry.  The quality of the transcoding was of high quality and Ryan did not see any of the issues that were present when using AMD's Avivo, as there is little point in quickly transcoding video if it ends up painful to watch.

We hadn't heard much else about Badaboom until today, when it was announce that version 2.0 will support Intel's new Quick Sync Video as well as NVIDIA's cards.  We don't have any benchmarks to show you how effective Sandy Bridge parts will be at accelerating transcoding but you can see the long list of pre-processing filters and learn a bit about Intel's media SDK on this page at Intel.

badaboom.gif

"Intel Quick Sync Video, built right into 2nd generation Intel Core processors, is breakthrough hardware acceleration that lets the user complete in minutes what used to take hours. Create DVDs or Blu-ray discs, cover video files for your media plater, and convert video for upload to your favorite social networking sites - all in a flash.

Badaboom uses Intel Quick Sync Video technology to transcode video files in just minutes. Why do videos need to be transcoded? In order for a video to play back on a device such as a smartphone or a tablet, it needs to be formatted to correct specifications. With so many different devices out there, odds are low a video from a camcorder will automatically play on all of them. That's where Badaboom comes in: it transcodes video files to play on hundreds of the most popular devices available today-and it does so quickly and easily."

NVIDIA Releases GeForce GTX 580M and 570M, Brings Optimus to Hardcore Gaming Laptops

Subject: Mobile | June 28, 2011 - 05:47 AM |
Tagged: nvidia mobile, nvidia, mobile graphics, gtx 580m, gtx 560m

The green team today announced the GTX 580M and GTX 570M, the newest high-end GPUs for gaming laptops. These parts succeed the GTX 485M and GTX 470M, respectively. According to NVIDIA, the GTX 580M will be the quickest mobile graphics solution on the market, while the GTX 570M will be 20% faster than the 470M it replaces.

table.png

Gaming performance samples show a substantial improvement over the previous generation. According to the press material, a single GTX 580M is capable of outputting over 30 frames per second at 1920x1080 at high detail in various games including Crysis 2, DIRT3, and Civilization V. These high marks are only further improved when the two GPUs are placed into SLI. In Crysis 2, for example, this configuration achieves over 70 FPS with detail set to Extreme Quality.

physx.jpg

Both the GTX 580M and 570M will support all of the company’s typical hardware features including PhysX, Nvidia 3D Vision, 3DTV Play, SLI, CUDA and OpenCL. In addition to this, these new mobile solutions will offer support of Optimus.

This is the first time that Optimus support has been offered in high-end mobile GPUs, and it could provide the green team with a significant advantage. In past reviews of Optimus enabled laptops, such as the ASUS N53, we’ve found that the feature made it possible to offer battery life on par with laptops that don’t have a discrete GPU. Optimus in the 580M and 570M will likely replicate this, making it possible for gamers to enjoy extreme gaming performance while plugged in and reasonable battery life while on the go.

verde.jpg

NVIDIA also continues to push its NVIDIA Verde driver program. For those who missed the initial announcement, Verde can be summed up as a monthly driver release program. The goal is to consistently improve performance and stability, giving owners of Nvidia GPUs a better long-term experience. Driver updates have proven to increase performance in the past, sometimes significantly, so these monthly updates are welcome.

The initial wave of 580M mobile graphics will be found in three laptops: the Alienware M18x, the Clevo P170HM3, and the Clevo P270WM. It’s reasonable to expect that both Clevo models will be picked up by various companies, such as Origin and Maingear, and released with some modifications under those brands. MSI will be the only company launching a 570M equipped laptop, in this case the MSI GT780R. Pricing has yet to be announced.

lineup.jpg

With the release of these new parts, NVIDIA has converted nearly all of its current components to the 5xx series brand. Only the “mainstream” GeForce 315M and 410M remain outside the fold.

UPDATE: Need some more proof of the power of the GTX 580M?  Here it is seen running the brand-new DX11 variant of Crysis 2:
