PC gaming is alive and well and hardware vendors are working to create unique features in their product lines to entice this niche audience. Gigabyte has always had a soft spot for gamers who want the best components for their LAN rigs so they can own their friends in any game genre they choose to play. Gigabyte has broadened their product line to include performance gaming mice, keyboards, and PC cases. They also have a line of "G1-Killer" motherboards that Gigabyte claims is designed with 3D gaming in mind. One of their latest boards in the G1-Killer series is the G1.Sniper M3, and just happen to have a sample that we are reviewing today.

The G1.Sniper M3 was designed into a micro ATX form factor that sports Intel's latest Z77 Express chipset and supports the third generation of Intel's LGA 1155 "Ivy Bridge" processors. It is challenging to pack enough performance features and overclocking options onto a micro ATX footprint, but Gigabyte's G1.Sniper M3 has broken the code in this department. This $180 board includes a digital power phase design with auto voltage compensation, dual UEFI BIOS, and an onboard Creative Sound Core3D quad-core audio processor for rich, high-definition audio.

More Ivy Bridge on Linux experiments

Tagged: Intel, opengl, opencl, linux, Ivy Bridge

Intel really seems to have taken the general criticism about the lack of Linux support during the initial release of Sandy Bridge to heart and made sure not to repeat the mistake with Ivy Bridge.  Phoronix have spent the last two months exhaustively testing the performance of the i7-3770K and today offer some general observations about the chip and Intel's support of open source.  Much of it is good news, like the performance of the OpenGL driver as well as its support for OpenGL 4.0 but some is not so good such as the fact that AMD's OpenCL for the CPU works better than Intel's implementation with neither running on the GPU yet.  Check out the other findings in the article.

"It has been 66 days since Intel formally introduced their Ivy Bridge processors as the 2012 successor to Sandy Bridge. My views on Intel Ivy Bridge (specifically the Core i7 3770K model) back on launch-day were very positive in terms of the Linux compatibility, CPU performance, and the HD 4000 graphics capabilities. Since then I've conducted dozens of additional tests looking at the Core i7 Ivy Bridge on Linux in different areas from comparative benchmarks to Microsoft Windows, trying to run BSD operating systems on the latest hardware, looking at the virtualization performance, compiler tuning, etc. Here is a recap of this additional Ivy Bridge testing that has happened over the past two months of near constant benchmarking."

Good work if you can get in, Intel starts researching wetware-hardware interaction

Subject: General Tech | June 27, 2012 - 04:35 PM |
Tagged: Intel Science Technology Center, social, research, Intel

Intel has earmarked $15 million to be spent over the next 5 years researching how people interact with their machines.  They will be focusing on the social aspect as opposed to hardware and software; trying to discover how people interact with their machines, from cell phones to servers as well as investigating how people would like to interact with their machines.  The Register believes that this is an attempt to work on the next generation of patents and to avoid the fate of Xerox's PARC.  While they invented many of the communications technologies which we take for granted today they never managed to capitalize on them successfully enough to survive in the market.  Since Intel has the money to invest in research and a demonstrated ability to capitalize on their intellectual property this expenditure makes sense and should help Intel remain at the top of the technological heap for quite a while.  In the mean time, it sounds like a great project to be working on.

"The new Intel Science Technology Center is a $15m program funding five years of research into social and anthropological research into how people use technology. Rather than focus on how hardware and software are used, the new center will be looking at how human wetware interacts with the resulting data."

A slightly lower cost Ivy Bridge

Just a couple of short months ago, Intel released the desktop versions of its latest CPU architecture codenamed Ivy Bridge – and officially named the Intel 3rd Generation Core Processor. Ivy Bridge has a much cleaner sound to it if you ask me.  

At launch, we tested and reviewed the highest-end offering, the Core i7-3770K, a quad-core HyperThreaded part that runs as fast as 3.9 GHz with Turbo Boost. It included the highest end processor graphics Intel has developed – the HD 4000. Currently selling for only $350, the i7-3770K is a fantastic processor, but isn't the bargain that many DIY PC builders are looking for. The new Core i5-3470 from Intel – the processor we are reviewing today – might be just that.

I am not going to spend time discussing the upgrades and benefits that the new Ivy Bridge processors offer over their predecessors, or the competition, from an architectural stand point. If you want some background on Ivy Bridge and why it does what it does, you'll want to read the first few pages of our original Core i7-3770K / Ivy Bridge review from April

The Core i5-3470 Processor

Interestingly, in the initial information from Intel about the Ivy Bridge processor lineup, the Core i5-3470 wasn't even on the list. There was a 3450 and 3550, but nothing in between. The Core i5-3470 currently sells for about $200 and compares with some other Ivy Bridge processors with the following specifications:

Intel Introduces Xeon Phi: Larrabee Unleashed

Subject: Processors | June 19, 2012 - 11:46 AM |
Tagged: Xeon Phi, xeon e5, nvidia, larrabee, knights corner, Intel, HPC, gpgpu, amd

Intel does not respond well when asked about Larabee.  Though Intel has received a lot of bad press from the gaming community about what they were trying to do, that does not necessarily mean that Intel was wrong about how they set up the architecture.  The problem with Larrabee was that it was being considered as a consumer level product with an eye for breaking into the HPC/GPGPU market.  For the consumer level, Larrabee would have been a disaster.  Intel simply would not have been able to compete with AMD and NVIDIA for gamers’ hearts.
 
The problem with Larrabee and the consumer space was a matter of focus, process decisions, and die size.  Larrabee is unique in that it is almost fully programmable and features really only one fixed function unit.  In this case, that fixed function unit was all about texturing.    Everything else relied upon the large array of x86 processors and their attached vector units.  This turns out to be very inefficient when it comes to rendering games, which is the majority of work for the consumer market in graphics cards.  While no outlet was able to get a hold of a Larrabee sample and run benchmarks on it, the general feeling was that Intel would easily be a generation behind in performance.  When considering how large the die size would have to be to even get to that point, it was simply not economical for Intel to produce these cards.
 
phi_01.jpg
 
Xeon Phi is essentially an advanced part based on the original Larrabee architecture.
 
This is not to say that Larrabee does not have a place in the industry.  The actual design lends itself very nicely towards HPC applications.  With each chip hosting many x86 processors with powerful vector units attached, these products can provide tremendous performance in HPC applications which can leverage these particular units.  Because Intel utilized x86 processors instead of the more homogenous designs that AMD and NVIDIA use (lots of stream units doing vector and scalar, but no x86 units or a more traditional networking fabric to connect them).  This does give Intel a leg up on the competition when it comes to programming.  While GPGPU applications are working with products like OpenCL, C++ AMP, and NVIDIA’s CUDA, Intel is able to rely on many current programming languages which can utilize x86.  With the addition of wide vector units on each x86 core, it is relatively simple to make adjustments to utilize these new features as compared to porting something over to OpenCL.
 
So this leads us to the Intel Xeon Phi.  This is the first commercially available product based on an updated version of the Larrabee technology.  The exact code name is Knights Corner.  This is a new MIC (many integrated cores) product based on Intel’s latest 22 nm Tri-Gate process technology.  The details are scarce on how many cores this product actually contains, but it looks to be more than 50 of a very basic “Pentium” style core;  essentially low die space, in-order, and all connected by a robust networking fabric that allows fast data transfer between the memory interface, PCI-E interface, and the cores.
 
intelphi.jpg
 
Each Xeon Phi promises more than 1 TFLOP of performance (as measured by Linpack).  When combined with the new Xeon E5 series of processors, these products can provide a huge amount of computing power.  Furthermore, with the addition of the Cray interconnect technology that Intel acquired this year, clusters of these systems could provide for some of the fastest supercomputers on the market.  While it will take until the end of this year at least to integrate these products into a massive cluster, it will happen and Intel expects these products to be at the forefront of driving performance from the Petascale to the Exascale.
 
phi_02.jpg
 
These are the building blocks that Intel hopes to utilize to corner the HPC market.  Providing powerful CPUs and dozens if not hundreds of MIC units per cluster, the potential computer power should bring us to the Exascale that much sooner.
 
Time will of course tell if Intel will be successful with Xeon Phi and Knights Corner.  The idea behind this product seems sound, and the addition of powerful vector units being attached to simple x86 cores should make the software migration to massively parallel computing just a wee bit easier than what we are seeing now with GPU based products from AMD and NVIDIA.  The areas that those other manufacturers have advantages over Intel are that of many years of work with educational institutions (research), software developers (gaming, GPGPU, and HPC), and industry standards groups (Khronos).  Xeon Phi has a ways to go before being fully embraced by these other organizations, and its future is certainly not set in stone.  We have yet to see 3rd party groups get a hold of these products and put them to the test.  While Intel CPUs are certainly class leading, we still do not know of the full potential of these MIC products as compared to what is currently available in the market.
 

The one positive thing for Intel’s competitors is that it seems their enthusiasm for massively parallel computing is justified.  Intel just entered that ring with a unique architecture that will certainly help push high performance computing more towards true heterogeneous computing.

AFDS 2012: AMD Wireless Display to compete against Intel WiDi with open standards

Subject: General Tech, Processors, Displays | June 10, 2012 - 06:45 PM |
Tagged: widi, Intel, awd, amd wireless display, amd, AFDS

While perusing through the listings and descriptions of sessions and presentations for the upcoming AMD Fusion Developer Summit, I came across an interesting one that surprised me.  Tomorrow, June 11th, at 5:15pm PST, you can stop by the Grand Hyatt in Bellevue to learn about the upcoming AMD Wireless Display technology.

AWD (AMD Wireless Display) is a multiple-platform application family to enable wireless display technologies much in the same way that Intel has been pushing with WiDi.  While Intel's take on it requires very specific Intel wireless controllers and is only recently, with the release of Ivy Bridge, getting the full-steam push from Intel, AMD's take on it is quite different.

widi02.jpg

Intel introduced WiDi in 2010

According to the brief on this AFDS session, AMD wants to create an API and SDKs for application developers to integrate AWD into software and to leverage the WiFi Alliance for an open-standards compliant front-end.  Using AMD APUs, the goal is provide lower latency for encoded video and audio while still using the required MPEG2TS wrapper.  We are also likely to learn that AMD hopes to make AWD open to a wider array of wireless devices.

AMD often takes this "open" approach to new technologies with mixed results - CUDA has been in place for many years while the adoption of OpenCL is only starting to take hold and 3D Vision still is the standard for 3D gaming on the PC.  

After having quite a few chances to use Intel's Wireless Display (WiDi) technology myself I can definitely say that the wireless approach is the one I am most excited with and that has the most potential to revolutionize the way we work with displays and computing devices.  I am eager to see what partners AMD has been working with and what demonstrations they will have for AWD next week.

Comprehensive Ivy Bridge testing on Ubuntu 12.04 LTS

Subject: Processors | June 8, 2012 - 03:51 PM |
Tagged: ubuntu, linux, Intel, Ivy Bridge, compiler, virtualization

Phoronix have been very busy lately, getting their heads around the functionality of Ivy Bridge on Linux and as these processor are much more compatible than their predecessors it has resulted in a lot of testing.  The majority of the testing focused on the performance of GCC, LLVM/Clang, DragonEgg, PathScale EKOPath, and Open64 on an i7-3770K using a wide variety of programs and benchmarks.  Their initial findings favoured GCC over all other compilers as in general it took top spot, with LLVM having issues with some of their tests.  They then started to play around with the instruction sets the processor was allowed to use, by disabling some of the new features they could emulate how the Ivy Bridge processor would perform if it was from a previous generation of chips, good to judge the improvement of raw processing power.  They finished up by testing its virtualization performance, with BareMetal, the Kernel-based Virtual Machine virtualization and Oracle VM VirtualBox.  You can see how they compared right here.

phoronix_ivy.png

"From an Intel Core i7 3770K "Ivy Bridge" system here is an 11-way compiler comparison to look at the performance of these popular code compilers on the latest-generation Intel hardware. Among the compilers being compared on Intel's Ivy Bridge platform are multiple releases of GCC, LLVM/Clang, DragonEgg, PathScale EKOPath, and Open64."
