As the Intel Developer Forum commences we finally learn a little bit about what Intel is attempting to do with the acquisition of McAfee among other tidbits. Malware is one of the banes of computing existence. Information is valuable, security is hard, and most people do not know either. Antimalware software remains a line of defense between you and infections in the event that your first three lines of defense (patching known security vulnerabilities in software; limiting inbound connections and permissions; and common sense) fail to help. While no antimalware software is anywhere near perfect Intel believes that getting protection a little deeper in the hardware will do a little more to prevent previously unknown exploits.
Great Norton’s Ghost!
According to McAfee’s website, DeepSAFE is a platform for security software to see more of what is going on in the hardware around the Operating System itself. They are being very cagey about what technology is being utilized both on their site as well as their FAQ (pdf) which causes two problems: firstly, we do not know exactly what processors support or will support DeepSAFE; secondly, we do not know exactly what is being done. While this is more details than we knew previously there are still more than enough holes to fill before we know what this technology truly is capable of.

While on stage during today's opening keynote at the Intel Developer Forum, Intel CEO Paul Otellini showed of a prototype processor running completely on a very small solar cell.

Running Windows 7 and a small animated GIF of a cat wearing headphones, the unannounced CPU was being powered only by a small solar panel with a UV light pointed at it. Though Intel didn't give us specific voltages or power consumption numbers they did say that it was running at "close to the threshold of the transistors". Assuming we are talking about the same or similar 22nm tri-gate transistors used in Haswell, we found this:
My mostly uneducated guess then was that they were able to run Windows 7 and this animation on a processor running somewhere around 0.1-0.2v; an impressive feat that would mean wonders for standby time and the all-day computing models. This is exactly what Intel's engineers have been targeting with their transistor and CPU designs in the last couple of years as it will allow Haswell to scale from desktop performance levels all the way to the smart phone markets on a single architecture.
Keep in mind only the CPU was being powered by the solar cell; the rest of the components including the hard drive, motherboard, etc were being powered by a standard power unit.
You can see the solar panel and UV light on the right hand side of this photo. Interestingly, when the presenter moved his hand between the light source and the panel, the system locked up, proving that it was indeed being powered by it.

The first keynote of the Intel Developer Forum is complete and it started with Paul Otellini discussing the high level direction for Intel in the future. One of the more interesting points made was not about Ivy Bridge, which we will all see very soon, but about Haswell, Intel's next microarchitecture meant to replace the Sandy Bridge designs sometime in late 2012 or early 2013. Expected to focus on having 8 processing cores, much improved graphics and the new AVX2 extenstion set, Haswell will also be built on the 3D tri-gate transistors announced over the summer.
Otellini describes Haswell's performance in two important metrics. First, it will use 30% less power than Sandy Bridge at the same performance levels. This is a significant step and could be the result of higher IPC as well as better efficiency thanks to the 22nm process technology.
Where Haswell really excels is apparently in the standby metric: as a platform it could use as much as 20x less power than current hardware. Obviously Intel's engineers have put a focus on power consumption more than performance and the results are beginning to show. The goals are simple but seemingly impossible to realize: REAL all-day power and more than 10 days of stand by time.

It is once again time for our annual pilgrimage to the land of the Golden Gate to spend a few days with our friends at Intel and the Intel Developer Forum. IDF is one of the most informative events that I attend and I am always impressed by the openness and detail with which Intel showcases its upcoming products and future roadmap. This year looks to be no different.
What do we have on the agenda? First and foremost, we expect to hear all about Ivy Bridge and the architecture changes it brings to the Sandy Bridge CPUs currently in the market. Will we see increased x86 performance or maybe increases in the likelihood of us recommending the integrated graphics? More information is set to be revealed on the 22nm tri-gate transistor as well as the X79 chipset and the Sandy Bridge-E enthusiast platform. SSDs and Ultrabooks are also set on the docket. It's going to be busy.
But what would a week in downtown San Francisco be without visits from other companies as well? We are set to meet with Lucid, MSI, ASUS, Gigabyte, Corsair, HP and of course, AMD. I expect we will have just as much to say about what each of these companies has on display as we do Intel's event.
I am planning on live blogging many of the sessions I will be attending so stay tuned to PC Perspective all week for the latest!!
Get notified when we go live!
