During Justin Rattner's closing keynote at the Intel Developer Forum he discussed the pending changes to the Many Integrated Core Architectures (MIC) that we previously knew as the Terascale projects. While we have heard about the Knights Ferry component for some time, and it was basically used a software development platform for Intel's many-core initiative.
Impressive to see at this stage, the upcoming Knights Corner product will actually be built on the new 22nm tri-gate transistors and with more than 50 cores. They haven't posted more details on what exactly ">50" refers to but it does mean that Intel continues to progress down this path and is going to be pushing the terascale computing projects into the future.
Rattner also indicated that not all of the cores on the many-core projects have to be identical and we will soon see designs that combine more than the x86 processors to make for truly heterogeneous computing platforms.
Research into the program continues including things like stacked and shared memory, new communications protocols like optical interconnects, etc. We are just as eager to see the fruits of this research as we were for its application to gaming and graphics that eventually failed.

Today is day 2 at the Intel Developer Forum and with the first keynote out of the way, we can share a few short details about Ivy Bridge that we didn't know before. First, the transistor count is 1.48 billion - a hefty jump over Sandy Bridge that had less than 1 billion.
There was also mention of a new power management feature that will allow interrupts from other hardware devices to go to other cores than Core0, which it had ALWAYS done in the past. This means that it can route it to a core that is already awake and doing some work and not wake up a sleeping core unless necessary.
We also saw the Ivy Bridge processor running the HAWX 2 benchmark, now with support for DX11.
If you look at the die image at the top of this post, you will also notice that it appears more of the die has been assigned to graphics performance than was allocated to it on Sandy Bridge. Remember that on AMD's Llano about 50% of the die dedicated to stream processors; it would appear that by adding support for DX11, nearly doubling performance and including required support for things like DirectCompute, Intel was forced to follow suit to some degree.
Mooly laughed at press taking pictures of the die as he had purposely modified the image to hide some of the details or distort them to prevent precise measurements. Still, it looks like about 33% of the new Ivy Bridge processor is dedicated to graphics and media. This is good news for consumers, but potentially very bad news for the discrete GPU market in notebooks and low end PCs.
Finally, Mooly Eden ended with a brief look at future Ultrabooks that will be based on the Ivy Bridge processor.
If you thought the current generation of Ultrabooks was sexy (as I do) then you will really like what is coming up next.

Tagged: gamescom, battlefield 3
DICE was at Gamescom in Germany showing off an assortment of new Battlefield 3 details through their booth and a short keynote speech. The vast majority of the keynote consisted of the two speakers playing Battlefield 3 co-op on the console. Aside from the live co-op demo there was a trailer from a more classic Battlefield map inhabited with 64 players and fighter aircraft. Check it out below, preferably in high resolution and fullscreen. You can then check out the unofficial BF3Blog for the complete weapon list with claymores and mortar launchers.
So Call of Duty was leaving a bar and the pub server asked, “Gotta jet?”
It was also recently revealed that Battlefield 3 would be locked to 30 frames per second on the consoles which drew fire from Activision who runs their game at 60 FPS. Their claim was that the added framerate is required to have a more responsive experience. Unfortunately as our previous article reporting on Mozilla’s stance on responsiveness shows: it is not as simple as 33.3ms versus 16.7ms latencies. Even under the assumption that the framerate is at its maximum you cannot tell the exact duration between input and TV draw without the use of a high-speed camera looking at both player-controller and monitor. Many frames could go by without even looking at the input loop and all the other dependent code on parallel out-of-sync threads that finally alter the state of the threads that draws what you should see. Be careful what you read folks; while yes, higher framerate gives the higher potential for lower latency between press and draw it is not necessarily the case. All of that said we will be on the PC which has its own set of methodologies for how to handle multi-process (there are still latencies inherent with any multiprocess game, but with different limits) and thus this is entirely irrelevant to us, but still a good learning experience regardless.

If you weren't at Quakecon 2011 last weekend and didn't get a chance to watch our live stream of the event, you can still catch it right here. What did we do at 3rd Annual PC Perspective Hardware Workshop? We gave out a TON of hardware and prizes thanks to our many sponsors (listing here) and also showed off some great case mods, some new technology including a 5 display capable Galaxy graphics card and of course, a demo from NVIDIA's own Tom Petersen.
Again, a HUGE thanks goes out to our sponsors for helping out with the event, providing interesting things to show off and prizes for all the gamers. We had a blast as did the 1100+ attendees and 2000+ viewers live online that day!! A big thanks specifically goes out to Corsair, NVIDIA and OCZ for exceptional help getting it all together!
Here is to next year...or who knows...maybe even sooner...? ;)

Tagged: rage, quakecon, id
The most important difference about Quakecon this year is that they can finally, for the first time in years, promote an upcoming in-house title. RAGE was definitely all the rage this year as John Carmack spent the majority of his keynote discussing the technical decisions made during the game for the 360, for the PS3, and for the PC. The biggest take-away that a lead game programmer could learn from the keynote is that you should never tell the artist team when approached about design specifications, “Make beautiful stuff and we’ll figure out how to make it work.” However, for the rest of us not on iD’s programming department, we get to see what a comment like that looks like in the new RAGE trailer.
Reminded of USENET a decade ago, “Syntax Error: Asking for the best computer, money is no object.”
Something has us believing that this will be a very profitable year for Bethesda’s parent company, Zenimax. With two large games, RAGE and Elder Scrolls V, coming out this autumn from Zenimax we hopefully should see them able to reinvest and grow over the coming years. As for the game itself, I get three distinct vibes from the most recent cinematic trailer: The first is Doom 3 which is most felt in the intro as the player is loaded into the pod-like device; the second is Fallout 3 from characters interact; the third vibe I cannot pin against any given game and mostly consists of the vehicular aspect of the trailer. What does it remind our readers of? (Registration not required for commenting.)

If you are hoping for fine cognac or fast storage you may be disappointed to find out that the Hennessey VelociRaptor 600 SC is a modified 2011 Ford F-150 Raptor SVT, but if you are into high performance automotives then you've another reason to come to QuakeCon. There will be 100 tickets available for the draw, which you will have to win during QuakeCon, perhaps even through the CaseMod contest that PC Perspective is judging again this year!
July 27, 2011 (Rockville, MD) – Ventrilo, the premier group voice communication program used in tournaments and multiplayer games, will once again participate in QuakeCon 2011, with the sponsorship its 4th annual “Ultimate Power Up” Sweepstakes at QuakeCon. In addition, the Company will also sponsor their newly added “Ventrilo RAGE Quick Drive” contest.
This year, one lucky attendee will drive away from QuakeCon 2011 in a brand-new 2011 Molten Orange Ford F-150 Raptor SVT, complete with the Hennessey VelociRaptor 600 SC upgrade package. Attendees will also have the chance to win their share of $10,000 cash as they compete in the “Ventrilo RAGE Quick Drive” contests held throughout the event. The 2011 Ford F-150 Raptor SVT Hennessey VelociRaptor 600 SC, valued at approximately $69,719, will be on display in the main exhibition area throughout the event.
“Once again we’d like to say a special thank you to Brian Knapp and everyone at Ventrilo for giving QuakeCon attendees the chance to drive home on Sunday with panache,” said Todd Hollenshead, president of id Software. “This brand new, 600 HP Super Cab Ford F-150 is not only 4WD, but is also supercharged for the best performance on roads or off—and in bandit infested Wastelands.”
“It is an honor to be a major sponsor of QuakeCon once again. We could not ask for a better opportunity to give back to the community that spawned the creation of Ventrilo.”said Brian Knapp, president of Flagship Industries. “The Ford F-150 Raptor SVT was specifically designed to run in the Baja 1000 desert race but can be used for every day street driving. Those wasteland bandits will never catch you when you have 600 horsepower at your disposal.”
The “Ultimate Power Up” winner will be randomly selected after the final “Ventrilo RAGE Quick Drive” contest at 9:30pm CST on Saturday, August 6th as part of the tournament finals event on the QuakeCon Dell Main Stage. A total of 100 coveted tickets for the Ford F-150 Raptor SVT Hennessey VelociRaptor 600 SC will be awarded to attendees throughout each day of the show in QuakeCon contests, random drawings, and other events.

Yes, I am still gaming away and getting destroyed in some StarCraft II but at least we are having fun. In between ass-whoopings I have been wandering around the BYOC looking for some interesting case mods. Here are a few I found interesting.
These aren't really mods but I like the idea of bringing a BYOC stand that puts the case and computing components over the display in use, saving space on the table and moving the heat closer to the ceiling.
Here is another example of the design but with a brightly lit overclocked and water cooled SLI configuration.
Probably my favorite for the event has been this Lego case that took about 2 years to create according to the owner. The crane on the left is fully workable and controllable via some software running on the system. My favorite part though: the HDD LED is routed to look like a Lego guy's welding light on the front!!
This Gigabyte branded case mod uses the company's new G1 Killer branded motherboards and focuses heavily on the green motif. The skull shape reservoir really completes the ensemble.
Finally, here is a random shot of some people lining up to play a game of "LAN Pong" involving tossing tennis balls into a bucket. The prizes were impressive though: a pair of NVIDIA Tegra 2 powered tablets.

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.
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.
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.
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!
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!
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?

There seems to always be a trade show going on at some corner of the ellipsoid world particularly at this time of the year. Down in Singapore the CommunicAsia 2011 exhibition is on until the 24th and news is starting to trickle out about advancements in communication technology. If you were holding your breath until Android reached version 3.2 on devices you can almost finally exhale, if you are still conscious because you can at best hold your breath for like 8 minutes and Android products are not that quick to ship. Yet.
Seventh floor… going up… ... WHAMMY BAR!!!
Huawei announced on the 21st that they are releasing a 7-inch tablet based on Android’s 3.2 release. The tablet will feature a dual-core 1.2 GHz processor from Qualcomm but no mention of how much system RAM it will contain as it still allegedly depends on partners. The capacitive touchscreen will be IPS-based at a 217 PPI pixel density. After a little trigonometry: a 7-inch screen will have a resolution somewhere between 1280x720 and 1366x768 if its pixel density is 217 pixels per inch. The unit itself is capable of outputting 1080p to an external display through HDMI. There are currently no details towards a price, but Huawei stated that there are no plans for a Wifi-only version. The unit is expected to ship in the third quarter of this year.

Tagged: opencl, amd, AFDS
If you are a developer of applications which requires more performance than a CPU alone can provide then you are probably having a gleeful week. Today Microsoft announced their competitor to OpenCL and we have a large write-up about that aspect of their keynote address. If you are currently an OpenCL developer you are not left out, however, as AMD has announced new tools designed to make your life easier too.
General Purpose GPU utilities: Because BINK won't satisfy this crowd.
(Logo trademark Apple Inc.)
AMD’s spectrum of enhanced tools includes:
- gDEBuger: An OpenCL and OpenGL debugger, profiler, and memory analyzer released as a plugin for Visual Studio.
- Parallel Path Analyzer (PPA): A tool designed to profile data transfers and kernel execution across your system.
- Global Memory for Accelerators (GMAC) API: Lets developers use multiple devices without needing to manage multiple data buffers in both the CPU and the GPU.
- Task Manager API: A framework to manage scheduling kernels across devices.
These tools and utilities should make the development of software easier and allow more developers to take the risk on the new technology. The GPU has already proven itself worthy of more and more important tasks and it is only a matter of time before it is finally ubiquitous enough that it is a default component as important as the CPU itself. As an ironic aside, that should spur the adoption of PC Gaming given how many people would have sufficient hardware.

Tagged: programming, microsoft, fusion, c++, amp, AFDS
During this morning's keynote at the AMD Fusion Developer Summit, Microsoft's Herb Sutter went on stage to discuss the problems and solutions involved around programming and developing for multi-processing systems and heterogeneous computing systems in particular. While the problems are definitely something we have discussed before at PC Perspective, the new solution that was showcased was significant.
C++ AMP (accelerated massive parallelism) was announced as a new extension to Visual Studio and the C++ programming language to help developers take advantage of the highly parallel and heterogeneous computing environments of today and the future. The new programming model uses C++ syntax and will be available in the next version of Visual Studio with "bits of it coming later this year." Sorry, no hard release date was given when probed.
Perhaps just as significant is the fact that Microsoft announced the C++ AMP standard would be an open specification and they are going to allow other compilers to integrated support for it. Unlike C# then, C++ AMP has a chance to be a new dominant standard in the programming world as the need for parallel computing expands. While OpenCL was the only option for developers that promised to allow easy utilization of ALL computing power in a computing device, C++ AMP gives users another option with the full weight of Microsoft behind it.
To demonstrate the capability of C++ AMP Microsoft showed a rigid body simulation program that ran on multiple computers and devices from a single executable file and was able to scale in performance from 3 GLOPS on the x86 cores of Llano to 650 GFLOPS on the combined APU power and to 830 GFLOPS with a pair of discrete Radeon HD 5800 GPUs. The same executable file was run on an AMD E-series APU powered tablet and ran at 16 GFLOPS with 16,000 particles. This is the promise of heterogeneous programming languages and is the gateway necessary for consumers and business to truly take advantage of the processors that AMD (and other companies) are building today.
If you want programs other than video transcoding apps to really push the promise of heterogeneous computing, then the announcement of C++ AMP is very, very big news.

Tagged: vliw, trinity, llano, fusion, evergreen, cayman, amd, AFDS
Well that was an interesting twist... During a talk on the next generation of GPU technology at the AMD Fusion Developer Summit, one of the engineers was asked about Trinity, the next APU to be released in 2012 (and shown running today for the very first time). It was offered that Trinity in fact used a VLIW4 architecture rather than the VLIW5 design found in the just released Llano A-series APU.
A shader unit from the VLIW4-based Cayman architecture
That means that Trinity APUs will ship with Cayman-based GPU technology (6900 series) rather than the Evergreen (5000 series). While that doesn't tell us much in terms of performance simply because we have so many variables including shader counts and clocks, it does put to rest the rumor that Trinity was going to keep basically the same class of GPU technology that Llano had.
Trinity notebook shown for the first time today at AFDS. Inside is an APU with Cayman-class graphics.
AMD is definitely pushing the capabilities of APUs forward and if they can stay on schedule with Trinity, Intel might find the GPU portion of its Ivy Bridge architecture well behind again.

Before the AMD Fusion Developer Summit started this week in Bellevue, WA the most controversial speaker on the agenda was Jem Davies, the VP of Technology at ARM. Why would AMD and ARM get together on a stage with dozens of media and hundreds of developers in attendance? There is no partnership between them in terms of hardware or software but would there be some kind of major announcement made about the two company's future together?
In that regard, the keynote was a bit of a letdown and if you thought there was going to be a merger between them or a new AMD APU being announced with an ARM processor in it, you left a bit disappointed. Instead we got a bit of background on ARM how the race of processing architectures has slowly dwindled to just x86 and ARM as well as a few jibes at the competition NOT named AMD.
As is usually the case, Davies described the state of processor technology with an emphasis on power efficiency and the importance of designing with that future in mind. One of the interesting points was shown in regard to the "bitter reality" of core-type performance and the projected DECREASE we will see from 2012 onward due to leakage concerns as we progress to 10nm and even 7nm technologies.
The idea of dark silicon "refers to the huge swaths of silicon transistors on future chips that will be underused because there is not enough power to utilize all the transistors at the same time" according to this article over at physorg.com. As the process technology gets smaller then the areas of dark silicon increase until the area of the die that can be utilized at any one time might hit as low as 10% in 2020. Because of this, the need to design chips with many task-specific heterogeneous portions is crucial and both AMD and ARM on that track.
Those companies not on that path today, NVIDIA specifically and Intel as well, were addressed on the below slide when discussing GPU computing. Davies pointed out that if a company has a financial interest in the immediate success of only CPU or GPU then benchmarks will be built and shown in a way to make it appear that THAT portion is the most important. We have seen this from both NVIDIA and Intel in the past couple of years while AMD has consistently stated they are going to be using the best processor for the job.
Amdahl's Law is used in parallel computing to predict the theoretical maximum speed up using multiple processors. Davies reiterated what we have been told for some time that if only 50% of your application can actually BE parallelized, then no matter how many processing cores you throw at it, it will only ever be 50% faster. The heterogeneous computing products of today and the future can address both the parallel computing and serial computing tasks with improvements in performance and efficiency and should result in better computing in the long run.
So while we didn't get the major announcement from ARM and AMD that we might have been expecting, the fact that ARM would come up and share a stage with AMD reiterates the message of the Fusion Developer Summit quite clearly: a combined and balanced approach to processing might not be the sexiest but it is very much the correct one for consumers.
