The Intel Core i7 2600K is the company’s top tier Sandy Bridge processor; or at least it was until now. CPU World discovered interesting part numbers on the company’s Material Declaration Data Sheet (MDDS) that suggests that there may be a new contender for the top spot. Specifically, the new part numbers are BX80623172700K and BXC80623172700K, which suggests that the new processor will be launched as the Intel Core i7 2700K.
CPU World's discovery of new part numbers.
The site suggests that the new 2700K will be a higher clocked version of the 2600K processor, including a 95 watt TDP, four cores, hyperthreading technology, and 8 MB of cache. Unfortunately, it is not clear just how much higher the 2700K will be clocked at; however, as an unlocked processor with relatively good binning, enthusiasts should be able to get some great overclocks out of them.
Have you upgraded to Sandy Bridge, or are you planning on skipping over it for another upgrade instead? Either way, I think it is a good thing to see Intel updating its current lineup while also pursuing Ivy Bridge and Sandy Bridge-E.

Very few things impress like a collection of 256 processor cores in a box. But that is exactly what we saw on our last visit to the floor at the Intel Developer Forum this year when I stopped by to visit friend-of-the-site Daniel Pohl to discuss updates to the ray tracing research he has been doing for many years now. This is what he showed us:
What you see there is a dual-Xeon server running a set of 8 (!!) Knights Ferry many-core processor discrete cards. Each card holds a chip with 32 Intel Architecture cores running at 1.2 GHz on it and each core can handle 4 threads for a total of 1024 threads in flight at any given time! Keep in mind these are all modified x86 cores with support for 16-bit wide vector processing so they are pumping through a LOT of FLOPS. Pohl did note that only 31-32 of the cores are actually doing ray tracing at any given time though as they reserve a couple for scheduling tasks, operating system interaction, etc.
Each of the the eight cards in the system is using a pair of 6-pin PCIe power connectors and they are jammed in there pretty tight. Pohl noted this was the only case they could find that would fit 8 dual-slot add-in cards into it so I'll take a note of that for when I build my own system around them. Of course there are no display outputs on the Knights Ferry cards as they were never really turned into GPUs in the traditional sense. They are essentially development and research for exascale computing and HPC workloads for servers though the plan is to bring the power to consumers eventually.
To run the demo the Knights Ferry ray tracing server was communicating over a Gigabit Ethernet connection to this workstation that was running game processing, interaction processing and more and passed off data about the movements of the camera and objects in the ray traced world to the server. The eight Knights Ferry cards then render the frame, the Xeon CPUs compress the image (8:1 using a standard Direct 3D format) and send the data across the network. All of this happens in real time with basically no latency issues when compared to direct PC gaming.
While the ray tracing game engine projects might seem a little less exciting since the demise of Larrabee, Pohl and his team have been spending a lot of time on learning how to take advantage of the x86 cores available. The Wolfenstein demo we have seen in past events has been improved to add things like HDR lighting, anti-aliasing and more.
Though these features have obviously been around in rasterization based solutions for quite a long time, the demo was meant to showcase the fact that ray tracing doesn't inherently have difficulty performing those kinds of tasks as long as the processing power is there and alotted to it.
I am glad to see the ray tracing research continuing at Intel as I think that in the long-term future, that is the route that gaming and other graphics-based applications will be rendering. And I am not alone - id Software founder and Doom/Quake creator John Carmack agreed in a recent interview we held with him.

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.

Tagged: mooly eden, Ivy Bridge, idf 2011, idf
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.

Yes, I realize the ASUS UX21 was first shown at Computex in June, but this was my first chance to get my hands on it and I have to say after using it for just a few minutes and comparing it to the aging Lenovo X201 that I am typing this on, I am in love with the form factor.
I don't have anything else to report yet - no performance metrics, no real-world testing, but I couldn't pass posting these few pictures of it. Enjoy!

Tagged: x79, sandy bridge-e, msi, idf 2011, idf
Many of Intel's partners are on hand at IDF to showcase upcoming products and I was able to stop by the MSI booth yesterday to get a peek into the future of the X79 chipset. This chipset will launch with the upcoming Sandy Bridge-E processors (for enthusiast) sometime later this year and introduce a new processor socket (Socket 2011) as well as some new features like dozens of PCI Express connections and quad-channel memory.
The flagship board on display was the X79A-GD65 (8D) that is one of the few X79 boards I have seen sporting 8 DIMM slots (hence the name) and capacities as high as 64GB! Most of the MSI features we have come to love on current motherboards are going to be on this line as well including Military Class components, OC Genie II and the much updated and improved ClickBIOS II.
The board is completely 3-Way SLI ready (and CrossFire as well) and sports three total PCI Express 3.0 slots at x16 bandwidth but also adds in three more PCIe 2.0 slots for good measure.
There are 4x USB 3.0 ports, 12x USB 2.0 ports, 4x SATA 6G ports and 4x SATA 3G ports. Needless to say the X79 platforms are going to be an enthusiast's dream.
MSI is also likely to include a new breakout box with X79 motherboards that will reside in a 5.25-in bay slot on your case (and honestly I need more things to use up there these days) and give you a couple of USB ports, an OC Genie button that will double as a BIOS reset button when held down, and even integrated WiFi and Bluetooth. The above photo is just a mock up but the plans are in place to deliver them with these new boards.
Finally, MSI did have the much improved and updated ClickBIOS II UEFI on display and without a doubt it kicks the first version's ass. We are working on a review that includes this new implementation so expect more on that soon.

Tagged: TSMC, idf 2011, idf, GLOBALFOUNDRIES
While learning about the intricacies of the Intel tri-gate 22nm process technology at the Intel Developer Forum, Senior Intel Fellow Mark Bohr surprised me a bit by discussing the competition in the foundry market. Bohr mentioned the performance advantages and competitive edge that the new 22nm technology offers but also decided to mention that other companies like TSMC, GlobalFoundries, Samsung and IBM are behind, and falling further behind as we speak.
When Intel introduced strained silicon in 2003, it took competition until 2007 to implement it. For High-K Metal Gate technology that Intel brought into market in 2007 it wasn't until 2011 that AMD introduced in its product line. Finally, with tri-gate coming in 2011, GlobalFoundries is talking about getting it implemented in the 2015 time frame.
Obviously those are some long delays but more important to note is that the gap between Intel and the field's implementations has been getting longer. Three years for strained silicon, three and a half for high K and up to four years for tri-gate. Of course, we could all be surprised to see tri-gate come from a competitor earlier, but if this schedule stays true, it could mean an increasing advantage for Intel's products over AMD's and eventually into ARM's.
This also discounts the occasional advantage that AMD had over Intel in the past like being the first to integrate copper interconnects (on the first Athlon) and the first to develop a Silicon-on-Insulator product (starting with the 130nm process); though Intel never actually adopted SOI.

Tagged: overclocking, amd fx, bulldozer
Although the record was set a few weeks ago, we didn't have a chance to see it until today. A group of overclockers pushed a new AMD FX 8150 Bulldozer chip up to 8.429GHz which breaks the old record for highest CPU frequency set with a Celeron 352. You need liquid helium to manage this so do not expect to see that kind of result with air cooling. If you check out [H]ard|OCP 's video coverage you will see the performance of water, phase change and LN2 with the FX8150, though you probably know about it already since you have watched Ryan's coverage.
"If you are wondering how well the new AMD FX CPU will overclock, you are not alone. AMD let us have some behind-the-scenes access a couple of weeks ago and is now allowing us to show off the results. We shot a lot of video and show you AMD FX overclocking on water, phase change, and liquid nitrogen."

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.
Paul on the left, Windows 7 in the center, prototype ultra-low power CPU on the right
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.

There is a sub-culture in the computing world that is more or less analogous to the world of NHRA drag racing: liquid nitrogen overclocking. And if you are really serious, liquid helium. During a press event in Austin, TX in August to discuss the upcoming Bulldozer processor, a team of overclockers pushed the new architecture to frequencies well beyond safety and well beyond where they should be. Without giving away the whole story yet, AMD was able to set a new frequency world record...
Sami Mäkinen and his team hit 8.429GHz on liquid nitrogen and liquid helium with a near-production FX processor sample. This bests the reigning record of 8.308 GHz that was hit on a Celeron processor with LN2.
On August 31, an AMD FX processor achieved a frequency of 8.429GHz, a stunning result for a modern, multi-core processor. The record was achieved with several days of preparation and an amazing and inspired run in front of world renowned technology press in Austin, Texas. This frequency bests the prior record of 8.309GHz, and completely blows away any modern desktop processor. Based on our overclocking tests, the AMD FX CPU is a clock eating monster, temporarily able to withstand extreme conditions to achieve amazing speed. Even with more conservative methods, the AMD FX processors, with multiplier unlocked throughout the range, appear to scale with cold. We achieved clock frequencies well above 5GHz using only air or sub-$100 water cooling solutions.
I was in attendance for the event and have to say that group put on a spectacular show and anytime you can play with liquid helium running at near absolute zero temperature, it's worth paying attention! In fact, I put together a video of the event that you can see below and if you haven't participated or seen something of this nature, it is worth checking out!!
Now I need to temper some dreams right now - the chances of you or I reaching these types of clock speeds on the Bulldozer CPUs upon release are pretty close to nil. What was more interesting was the casual overclocking we saw pushing upwards of 4.8+ GHz without breaking a sweat and that is what we will be investigating with our review of the processor later this year.
Update: Here is the screenshot from the official HWBot frequency rankings as well as a different video created by AMD themselves summarizing the event.

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!!

Tagged: trinity, llano, bulldozer, APU, amd
AMD has not only started announcing quite a few future processors, but has also gone a bit crazy with all of the code names for said products. Admittedly, when the news broke that Trinity APU specifications were revealed, I had to do a bit of digging to figure out just what the Trinity APU was (exactly). In the end, the APU (accelerated processing unit) is similar in composition to Llano except with a bulldozer based CPU core and upgraded GPU. The bulldozer core aspect is what threw me for a bit of a loop in that I had a difficult time figuring out how the CPU core could be based on bulldozer when bulldozer hasn’t even been released ;). Hopefully that long introduction helps somewhat in clearing up what Trinity is.
Specifically, the new Trinity APU will debut with AMD’s new “Piledriver” (more code names!) architecture, and include a Radeon HD 7000 series GPU and Bulldozer based CPU core. Futher, the Trinity APU will come in both notebook and desktop flavors titled “Comal” and “Virgo” respectively. AMD notes that the improvements in the CPU and GPU cores will result in up to a 50% performance increase over the current Llano A Series APUs. While the 50% number is measuring pure gigaflop performance, even if the real world speed increase is not as noticeable in everyday usage, it is still a nice bump in performance.
On the availability front, AMD has slated the processor for release in 2012; however, Semi Accurate believes that the APU may well debut much sooner than expected. The site further quoted sources who stated that “CES is a distinct possibility for a soft launch, and maybe more.” More tidbits of information can be had here.

Tagged: a8-3850, amd, llano, overclocking, APU
Legit Reviews decide that they really wanted to be able to show the overclocking results you can expect from the AMD A8-3850, so they picked up eight of the chips to test each for overclocking ability. There have been examples in the past of chips with a wide variety of overclocking limits which was often decided by the chip revision but not in all cases. The test results show that all but two of the chips hit a stability issue when being pushed beyond 3679.5MHz, so you can take that as the most likely result that your chip will provide. The two outlying chips will be exceptional, in one case in a bad way which you can see in the full review.
"When AMD released the 'Lynx' desktop platform back in June 2011, our motherboard reviewer ran into some bad luck when overclocking the processor. When you get a new platform setup for the very first time you really don't know what to expect and it does take some time to learn all the quirks and nuances of a new processor and motherboard. We recently ordered in six more processors and then overclocked all seven of them to see what the best one would be for our test system!"

Phoronix is still satisfying their curiosity about the performance of Llano under Linux. To that end they assembled an A8-3850 with Gigabyte's GA-A75M-UD2H motherboard, 2GB of DDR3 memory, and a 60GB OCZ Vertex 2 SSD and installed Ubuntu 11.04 64-bit, GNOME 2.32.1, X.Org Server 1.10.1, and an EXT4 file-system. To power the system they had a few choices but unfortunately the one they were most interested in, AMD's Open64 4.2.4, failed to compile. That left them with two versions of GCC and Clang to test in a variety of benchmarks. There is still some work to do to bring all of the power of Llano to Linux, but for now this will give you a good idea which to use.
"Last week were a set of AMD Fusion A8-3850 Linux benchmarks on Phoronix, but for you this week is a look at the AMD Fusion "Llano" APU performance when trying out a few different compilers. In particular, the latest GCC release and then using the highly promising Clang compiler on LLVM, the Low-Level Virtual Machine."

AMD today announced three new Accelerated Processing Units (APU) to bolster up the mobile lineup. Specifically, two new E-Series and one new C-Series APU are inserting themselves into the lineup. The new chips bring enhanced graphic capabilities, HDMI 1.4a, and DDR3 1333 support. "Today's PC users want stunning HD graphics and accelerated performance with all-day battery life and that's what AMD Fusion APUs deliver," said Chris Cloran, vice president and general manager, Client Division, AMD.
According to MaximumPC, the new E-450 APU takes the top slot, bringing two CPU cores clocked at 1.65GHz, a Radeon HD 6320 GPU clocked at a base of 508MHz and maximum of 600MHz, and a power sipping TDP of 18 watts. The second new E-Series APU carries the same 18 watt TDP and dual CPU cores as the E-450; however, it is clocked at a lower 1.3GHz. Further, the chip’s Radeon HD 6310 GPU is clocked at 488MHz. The new E-Series APUs feature battery life increases to the tune of up to 10.5 hours of Windows idle time.
The new C-Series APU is the C-60, and is a 1GHz dual core chip with a Radeon HD 6290 GPU. The APU is able to turbo its CPU cores to a maximum of 1.33GHz, while the GPU has a base clock of 276MHz and a maximum clock speed of 400MHz. Further, the chip has a 9 watt TDP, and boasts 12.25 hours of “resting battery life,” which AMD benchmarked using Windows Idle on a C-60 based netbook.
Currently, AMD has shipped more than 12 million APUs, and more than five million of the C-Series and E-Series processors in Q2 2011. More information on the specific benchmarking metrics AMD used can be found here.
