I cannot do it captain! I don't have the not enough power!
We have been discussing the ultra-low power state of Haswell processors for a little over a week and how it could be detrimental to certain power supplies. Power supply manufacturers never quite expected that you could have as little as a 0.05 Amp (0.6W) draw on the 12V rail without being off. Since then, companies such as Enermax started to list power supplies which have been tested and are compliant with the new power requirements.

Above is Corsair's slightly incomplete chart as of the time it was copied from their website, 3:30pm on May 10th, 2013; so far it is coming up all good. Their blog should be updated as new products get validated for the new C6 and C7 CPU sleep states.
The best part of this story is just how odd it is given the race to arc-welding (it's not a podcast so you can't Bingo! hahaha!) supplies we have been experiencing over the last several years. Simply put, some companies never thought that component manufacturers such as Intel would race to the bottom of power draws.

Update: Did you miss the live stream? Watch the on-demand replay below and learn all about the Frame Rating system, FCAT, input latency and more!!
I know, based solely on the amount of traffic and forum discussion, that our readers have really adopted and accepted our Frame Rating graphics testing methodology. Based on direct capture of GPU output via an external system and a high end capture card, our new systems have helped users see GPU performance a in more "real-world" light that previous benchmarks would not allow.
I also know that there are lots of questions about the process, the technology and the results we have shown. In order to try and address these questions and to facilitate new ideas from the community, we are hosting a PC Perspective Live Stream on Thursday afternoon.
Joining me will be NVIDIA's Tom Petersen, a favorite of the community, to talk about NVIDIA's stance on FCAT and Frame Rating, as well as just talk about the science of animation and input.
The primary part of this live stream will be about education - not about bashing one particular product line or talking up another. And part of that education is your ability to interact with us live, ask questions and give feedback. During the stream we'll be monitoring the chat room embedded on http://pcper.com/live and I'll be watching my Twitter feed for questions from the audience. The easiest way to get your question addressed though will be to leave a comment or inquiry here in this post below. It doesn't require registration and this will allow us to think about the questions before hand, giving it a better chance of being answered during the stream.
Frame Rating and FCAT Live Stream
11am PT / 2pm ET - May 9th
So, stop by at 2pm ET on Thursday, May 9th to discuss the future of graphics performance and benchmarking!

Tagged: Volcanic Islands, radeon, ps4, amd
So the Southern Islands might not be entirely stable throughout 2013 as we originally reported; seismic activity being analyzed suggests the eruption of a new GPU micro-architecture as early as Q4. These Volcanic Islands, as they have been codenamed, should explode onto the scene opposing NVIDIA's GeForce GTX 700-series products.
It is times like these where GPGPU-based seismic computation becomes useful.
The rumor is based upon a source which leaked a fragment of a slide outlining the processor in block diagram form and specifications of its alleged flagship chip, "Hawaii". Of primary note, Volcanic Islands is rumored to be organized with both Serial Processing Modules (SPMs) and a Parallel Compute Module (PCM).
So apparently a discrete GPU can have serial processing units embedded on it now.
Heterogeneous Systems Architecture (HSA) is a set of initiatives to bridge the gap between massively parallel workloads and branching logic tasks. We usually make reference to this in terms of APUs and bringing parallel-optimized hardware to the CPU. In this case, we are discussing it in terms of bringing serial processing to the discrete GPU. According to the diagram, the chip within would contain 8 processor modules each with two processing cores and an FPU for a total of 16 cores. There does not seem to be any definite identification whether these cores would be based upon their license to produce x86 processors or their other license to produce ARM processors. Unlike an APU, this is heavily skewed towards parallel computation rather than a relatively even balance between CPU, GPU, and chipset features.
Now of course, why would they do that? Graphics processors can do branching logic but it tends to sharply cut performance. With an architecture such as this, a programmer might be able to more efficiently switch between parallel and branching logic tasks without doing an expensive switch across the motherboard and PCIe bus between devices. Josh Walrath suggested a server containing these as essentially add-in card computers. For gamers, this might help out with workloads such as AI which is awkwardly split between branching logic and massively parallel visibility and path-finding tasks. Josh seems skeptical about this until HSA becomes further adopted, however.
Still, there is a reason why they are implementing this now. I wonder, if the SPMs are based upon simple x86 cores, how the PS4 will influence PC gaming. Technically, a Volcanic Island GPU would be an oversized PS4 within an add-in card. This could give AMD an edge, particularly in games ported to the PC from the Playstation.
This chip, Hawaii, is rumored to have the following specifications:
- 4096 stream processors
- 16 serial processor cores on 8 modules
- 4 geometry engines
- 256 TMUs
- 64 ROPs
- 512-bit GDDR5 memory interface, much like the PS4.
20 nm Gate-Last silicon fab process
- Unclear if TSMC or "Common Platform" (IBM/Samsung/GLOBALFOUNDRIES)
Softpedia is also reporting on this leak. Their addition claims that the GPU will be designed on a 20nm Gate-Last fabrication process. While gate-last is considered to be not worth the extra effort in production, Fully Depleted Silicon On Insulator (FD-SOI) is apparently "amazing" on gate-last at 28nm and smaller fabrication. This could mean that AMD is eying that technology and making this design with intent of switching to an FD-SOI process, without a large redesign which an initially easier gate-first production would require.
Well that is a lot to process... so I will leave you with an open question for our viewers: what do you think AMD has planned with this architecture, and what do you like and/or dislike about what your speculation would mean?

If, on the other hand, you wish to see an example of a large application compiled for the browser: would Unreal Engine 3 suffice?
Clearly a computer hardware website would take the effort required to run a few benchmarks, and we do not disappoint. Epic Citadel was run in its benchmark mode in Firefox 20.0.1, Firefox 22.0a2, and Google Chrome; true, it was not run for long on Chrome before the tab crashed, but you cannot blame me for trying.
Each benchmark was run at full-screen 1080p "High Performance" settings on a PC with a Core i7 3770, a GeForce GTX 670, and more available RAM than the browser could possibly even allocate. The usual Firefox framerate limit was removed; they were the only tab open on the same fresh profile; the setting layout.frame_rate.precise was tested in both positions because I cannot keep up what the state of requestAnimationFrame callback delay is; and each scenario was performed twice and averaged.
- layout.frame_rate.precise true: 54.7 FPS
- layout.frame_rate.precise false: 53.2 FPS
Firefox 22.0a2 (asm.js)
- layout.frame_rate.precise true: 147.05 FPS
- layout.frame_rate.precise false: 144.8 FPS
Google Chrome 26.0.1410.64
It is also very enticing for Epic as well. A little over a month ago, Mark Rein and Tim Sweeney of Epic were interviewed by Gamasutra about HTML5 support for Unreal Engine. Due in part to the removal of UnrealScript in favor of game code being scripted in C++, Unreal Engine 4 will support HTML5. They are working with Mozilla to make the browser a reasonable competitor to consoles; write once, run on Mac, Windows, Linux, or anywhere compatible browsers can be found. Those familiar with my past editorials know this excites me greatly.
So what do our readers think? Comment away!
Good effort goes a long way
The wait has been long and anxious for Heart of the Swarm, the expansion to 2010's StarCraft 2: Wings of Liberty. Blizzard originally hinted at a very rapid release schedule which did not exactly come to fruition. The nearly three years of development time for Heart of the Swarm is longer than a single studio spends on a full Call of Duty title; although, one could make a very credible argument that a Blizzard expansion requires more effort to create than said complete Call of Duty title.
But as Duke Nukem Forever demonstrated, a long time in development does not guarantee a fully baked product coming out the other end.
Blizzard games have always been highly entertaining albeit without deep artistic substance; their games are not first on the list for a university literature syllabus. But, there is a lot of room in life for engaging entertainment. In terms of the PC, Blizzard has always been one of the leading developers for the platform; they know how to deliver an exceptional PC experience if they choose to.

Tagged: video, pcper, Indiegogo
UPDATE 4/26/13: We are extremely excited to see that we have met our first goal for our Indiegogo project! We are eternally grateful for our fans and readers that are supporting us in this endeavor. We are going to start putting together orders for the set materials and I am very excited about the direction this is pointing us in. There is still room to improve the project though and we have lots of great perks available for those of you that are still looking to contribute to the cause! Oh, and we should have our T-shirt design ready early next week as well. Thank you EVERYONE for reading PC Perspective!!
And for those of you looking for a bit more insight into our total goals, here is another mock up of the set!
Yesterday evening, the team at PC Perspective launched a project that will help us grow and expand our coverage of technology and computer hardware. Using the crowd funding service called Indiegogo.com, we are doing a fund drive to help improve the quality of our video content and enable us to do more, unique styles of content.
If you are anything like us, you love technology. Motherboards, graphics cards, processors, SSDs, monitors, laptops, tablets, cell phones and more. And you also love reading about them, hearing about them and seeing them, dissecting them and finding out what makes them tick.
I am confident that high quality video content is the future of our medium and while we have been able to do quite a lot with the basic technology and setup we have here today, my goal is to be able to bring the readers regular, high quality video content on all aspects of technology. We want to not only have video reviews for products but we want to be able to do near-daily content updates on the news of the day while balancing that with long-form interviews of personalities that make the industry function. We have dabbled in some of these content types and the responses have been great, but we need a higher quality setup to really do it right.
Our goal with this project is to build the funds necessary to turn our office in Florence, KY into a high tech video production outlet that starts with a quality set design and better quality equipment.
Other than supporting one of your favorite online outlets, we have also lined up some sweet perks for contributors to our project. We have ad-free versions of the site, Tshirts and access to the PC Perspective Gold Club that has some pretty ridiculous giveaways! If you support us even further you can get some individual time with our team to tell us why you supported us, answer your questions or even join us for an episode of the PC Perspective Podcast!
Come visit the offices, join the process of creating a new show or make fun of Josh's laugh in person - it's all possible!
So if you have the means and you want to support our cause, if you have enjoyed any of our articles, podcasts or video reviews, consider helping to fund our project!

Operators are standing by...
Of course Apple is not a primary manufacturer of LCD panels; like everyone else, they buy their panels from someone like LG. Due to how much Apple loves IPS technology, which I cannot blame them for, they in fact do purchase their displays from LG.
If you have an itchy soldering iron, so can you.
According to EmertHacks, the LG part number for retina iPad screens is LP097QX1-SPA1. The blog post states that he could find the panel for as cheap as $55, but my own digging game up with costs between $60 and $200 plus shipping. These panels are mostly destined to iPad repair shops, but you can give it a better home.
With under $20 of other parts, this panel could be attached to a DisplayPort connection. All said and done, you could have a 2048x1536 9.7" display with an 800:1 static contrast ratio for about $70.

The latest rumors, based on registry digging and off-the-record testimony, claims that Windows 8.1 will including the option of booting directly into the desktop. A bold claim such as this requires some due diligence. Comically, the attempts to confirm this rumor has unearthed another: the start button, but not necessarily the start menu, could return. On the record, Microsoft also wants to be more open to customer feedback. Despite these recent insights into the future of Windows, all's quiet with the worst aspect of modernization.
Mary Jo Foley, contributor to ZDNet and very reliable bullcrap filter for Microsoft rumors, learned from a reliable source that the Start Button might have a place in the modern Windows. Quite the catch while fishing to validate a different rumor; she was originally investigating whether Microsoft would consider allowing users to boot direct to desktop via recently unearthed registry keys. Allegedly both are being planned for at least some SKUs of Windows 8.1, namely the Professional and Enterprise editions.
But, as usual for Microsoft, the source emphasized, "Until it ships, anything can change." No-one was clear about the Start Button from a functional standpoint: would it be bound to display the Start Screen? Would it be something more?
Personally, I liked the modern Windows interface. Sure, it is messed up on the modern-side when it comes to multiple monitor support, but that can easily be fixed. As you will note, I am still actively boycotting everything beyond Windows 7 and this news will not change my mind. We are bickering over interface elements when the real concern is the deprecation of user control. Outside of the desktop: the only applications you can use are from the Windows Store or Windows Update; the only websites you can browse are ones which Internet Explorer can render; and the only administrator is Microsoft.
Imagine if Microsoft is told by a government that its citizens are not allowed encryption applications.
The Windows Store is clearly modeled by, and about as messed up as, the Xbox Marketplace. Even if your application gets certified, would Microsoft eventually determine that certification fees should be the burden of the developer? That is how it is on the Xbox with each patch demanding a price tag of about $40,000 after the first-one-free promotion. That would be pretty hard to swallow for an open-source application or a cute game that a teenage woman makes for her significant other as a Valentine's gift.
Microsoft's current Chief Financial Officer, Peter Klein, stated in his third quarter earnings release that Windows Blue, "Further advances the vision of Windows 8 as well as responds to customer feedback." Despite how abrupt this change would seem, the recent twitchy nature should not come as a surprise; Microsoft has had a tendency to completely change course on products for quite some time now. Mary Jo mentioned how Microsoft changed course on UAC but even that is a bad example; a better one is how Microsoft changed from its initial assertions that Windows 8 Developer Preview would not be shaped by customer feedback.
A lot has changed between Developer Preview and RTM.
Then again, we can hope that Microsoft associates this pain with love for the desktop. I would be comfortable with the modern Windows if we were given a guarantee that desktop x86 applications would forever be supported. I might even reconsider using and developing applications if they allow loading uncertified metro-style applications and commit to never removing that functionality.
I can get used to a new method of accessing my applications. I can never get used to a middle-man who only says "no". If Microsoft is all ears, I hope we make this point loud and clear.

So, news which might excite our readers: we are going to try reviewing video games.
Of course, the first thing which needs to be addressed when reviewing games is our grading system. Games, in particular, are a very artful medium and as such it does not entirely make sense to quantize its qualities.
The simple answer is, we will not.
Step back and consider how we review hardware: we run some benchmarks, we discuss the features in often numbing detail, and we assign an award-badge to the product according to our opinion. A hardware could receive no merit; it could receive a bronze, silver, or gold medal; finally, the truly extraordinary products will receive an Editor's Choice Award. If you think about it, these can transfer quite easily to video game reviews.
Our expectation is to apply two ratings to every review: a badge and a number.
A badge is very good at qualifying our assessment of a product whereas numerical scores are very good at quantifying a derivable value. We, collectively as PC gamers, have certain expectations for games and they usually demand more than the impressions of a typical console gamer. Simultaneously, we tend to be an afterthought for a lot of titles; yes, I am being generous even with that statement. Many games are outright broken, crippled by DRM, or otherwise demonstrate in very obvious terms that our money is somehow inferior. On the other hand, there are games which go above and beyond reasonable expectations held by PC gamers, and even some unreasonable ones, and are rarely hailed for it.
We are not able to judge the artistic qualities of a game using a numerical score, but we can judge its technical merits using a numerical rubric.
And so exists our planned review metric. The main point is that there will not be any definite rank-order to each game, at least from an artistic standpoint. A game is allowed to really well on one category and really terribly on another. If you are concerned with the game itself, keep more of an eye toward which award we gave it. If you are concerned about how well the game exists as a PC title, take a look at the numerical score.
There are of course caveats to this method. A viewer who looks solely at the numerical score will not know much, if anything, about the game itself. The numerical score is just a gauge for the level of effort put into the PC version.
Then again, would you expect any less from a website called "PC Perspective" which reviews products with a blend of explanation of its qualitative features mixed in with strict quantitative benchmarking?
Lastly, this is not about whether a game is "better" on a PC or on a console. Developers are free to focus on whatever platform they desire. A game designed around a console and ported to the PC will still get a great score if the finished result exhibits a "great" level of care. Likewise, even if your game is PC-exclusive, do not expect us to give it a great score if it cannot alt-tab worth a damn and is wrapped in DRM which roots our system using kernel-mode drivers.
It is not particularly hard to make a great PC experience, all it takes is effort. Fortunately, that is a property that we can assign an honest grade to.
We would really like to hear your feedback on this. Drop a line in the comments below!
Taking a Fresh Look at GLOBALFOUNDRIES
It has been a while since we last talked about GLOBALFOUNDRIES, and it is high time to do so. So why the long wait between updates? Well, I think the long and short of it is a lack of execution from their stated roadmaps from around 2009 on. When GF first came on the scene they had a very aggressive roadmap about where their process technology will be and how it will be implemented. I believe that GF first mentioned a working 28 nm process in a early 2011 timeframe. There was a lot of excitement in some corners as people expected next generation GPUs to be available around then using that process node.
Fab 1 is the facility where all 32 nm SOI and most 28 nm HKMG are produced.
Obviously GF did not get that particular process up and running as expected. In fact, they had some real issues getting 32 nm SOI running in a timely manner. Llano was the first product GF produced on that particular node, as well as plenty of test wafers of Bulldozer parts. Both were delayed from when they were initially expected to hit, and both had fabrication issues. Time and money can fix most things when it comes to process technology, and eventually GF was able to solve what issues they had on their end. 32 nm SOI/HKMG is producing like gangbusters. AMD has improved their designs on their end to make things a bit easier as well at GF.
While shoring up the 32 nm process was of extreme importance to GF, it seemingly took resources away from further developing 28 nm and below processes. While work was still being done on these products, the roadmap was far too aggressive for what they were able to accomplish. The hits just kept coming though. AMD cut back on 32nm orders, which had a financial impact on both companies. It was cheaper for AMD to renegotiate the contract and take a penalty rather than order chips that it simply could not sell. GF then had lots of line space open on 32 nm SOI (Dresden) that could not be filled. AMD then voided another contract in which they suffered a larger penalty by opting to potentially utilize a second source for 28 nm HKMG production of their CPUs and APUs. AMD obviously was very uncomfortable about where GF was with their 28 nm process.
During all of this time GF was working to get their Luther Forest FAB 8 up and running. Building a new FAB is no small task. This is a multi-billion dollar endeavor and any new FAB design will have complications. Happily for GF, the development of this FAB has gone along seemingly according to plan. The FAB has achieved every major milestone in construction and deployment. Still, the risks involved with a FAB that could reach around $8 billion+ are immense.
2012 was not exactly the year that GF expected, or hoped for. It was tough on them and their partners. They also had more expenses such as acquiring Chartered back in 2009 and then acquiring the rather significant stake that AMD had in the company in the first place. During this time ATIC has been pumping money into GF to keep it afloat as well as its aspirations at being a major player in the fabrication industry.
