An aspiring overclocker and Coolaler forum go-er "u48802109" got his/her hands on an engineering sample and set out to see just how far he could push the upcoming Intel Core i7 2700K processor using air cooling. In an exciting result, the overclocker was able to achieve a stable 5 GHz overclock on the 2700K with a 100 MHz bus speed and 50x multiplier. Even more amazing are the voltage and temperature results (keeping in mind that we don't know the particular HSF being used) of the overclock. Specifically, they were able to hit 5 GHz with 1.384 V and hit a maximum temperature of 65 C.
A zoomed in look at the CPU-Z readout.
While air cooling may not be able to support going to much higher frequencies, water cooling could certainly open up even more headroom in the chip. Also, keeping in mind that these are engineering samples, it will be interesting to see where the Core i7 2700K falls once it starts rolling out to consumers. If these results hold out, it does seem like it may just be worth it to pay a few extra bucks and eschew the 2600K for new builds. What are your thoughts, are these results encouraging to you? You can see the full overclocking results here.

Intel has held the performance lead for several processor generations now, and while AMD is still technically in the game for home theater PC and budget builds, many enthusiasts have moved to Intel for gaming and high performance computers. Many of those people have also held hope that the chip manufacturer would eventually come back strong and maintain some level of competition in the industry. As we move closer to AMD's Bulldozer launch (which seems to have been confirmed for October 12th), enthusiasts and reviewers alike are clamoring to answer a long awaited question: "will Bulldozer give Intel a run for its money?"
According to website Donanim Haber, enthusiasts’ high hopes may finally be realized. The site has posted several benchmarks results that indicate Bulldozer is not only cheaper than Sandy Bridge, but performs on par with Intel’s top end Sandy Bridge chips. In many tests, the AMD FX 8150 CPU’s eight core performance matches the multi-threaded (8 threads, 4 cores) performance of Intel’s high end Core i7 2600k processor.
In the benchmarks that the site performed, the AMD FX 8150 was tested against the Intel Core i7 980X for 1080p gaming and the Core i7 2500k and 2600k for multi-threaded performance. In the graph shown above, the AMD Bulldozer CPU was roughly on par with the i7 980X, trading wins in some games and providing a similar level of performance in others. The AMD processor won in the Metro 2033 and Lost Planet benchmarks, but was slightly slower in Civilization V and F1 2010. In AVP and Batman (among others), the two competing processors saw equal results.
They also ran several benchmarks using highly multi-threaded programs to take advantage of the many-core designs of the AMD and Intel processors, including WinRar 4, Handbrake, 7zip, and wPrime 32M. The eight core AMD FX 8150 Bulldozer processor was tested against both an Intel Core i5 2500k and a Core i7 2600k. The AMD CPU came out ahead in 7zip, wPrime 32M, and Bibble 5.0. It was slower than the Core i7 2600k in the WinRar 4 tests and slower than both the 2500k and 2600k in the ABBYY OCR10 benchmarks. In the other tests, the AMD processor kept pace with or was only slightly behind the top end Intel 2600k CPU.
From the leaked benchmarks (which you can read here), AMD’s new Bulldozer CPUs have made an admirable showing. Should these benchmarks hold true, Intel will have some serious competition on its hands, something that the company has not had to deal with in a long time. Whether Bulldozer will result in price cuts or ramped up production on the Intel side remains to be seen; however, the results are not going to be easy for Intel to ignore.
Stay tuned to PC Perspective for more Bulldozer news in the coming weeks.

Intel plans to refresh its entry level and mid-range Sandy Bridge desktop processor lineup with seven new models and accompanying price drops. The new models include the Pentium G630, G630T, and G860 on the low end, and the Core i5 2320 on the high end. Making up the middle ground are the Core i3 2120T, i3 2125, and i3 2130 processors.
CPU-World reports that September and October will both see price reductions in certain Sandy Bridge processor SKUs. September will see price reductions in all mid and low power Core i5 and i7 processors. Specifically, the Core i5 processors will be reduced by as much as $11, while the Core i7-2600S will see a price cut of $12. October will bring price cuts for the low end Pentium and Core i3 processors. The Pentium CPUs will see a price cut of $11 and the Core i3 2120 will be cut by $21.
CPU World has a detailed chart of the individual chip prices which you can check out here. Will these price reductions be enough to entice you to buy into Sandy Bridge, or are you holding off upgrading until Ivy Bridge?

Tagged: steelseries, Sensei, gaming mouse, cpu, arm
Bit-Tech reports that popular gaming peripheral maker SteelSeries will be unveiling a new mouse at GamesCon next week. The new gaming mouse, dubbed the Sensei is a dark, ambidextrous affair with LED powered logo, wheel, and sensitivity indicator in addition to an LCD screen on the bottom of the mouse to configure features.
The Sensei mouse has a large SteelSeries logo towards the back of the palm rest. The lighting of the logo supports up to 16.8 million colors. The body is comprised of metal with a non-slip grip coating, and features eight buttons. Bruce Hawver, SteelSeries’ CEO stated “The Sensei is really the culmination of thousands of hours of research and testing with competitive players.” In keeping with the competitive gamer theme, SteelSeries has endowed the Sensei with advanced macro capabilities, including the ability to record timed and layered macros with keystrokes.
On the sensor front, the Sensei features a sensitivity range of 1 to 5,700 counts per inch (SteelSeries’ DPI-like system of measurement). Further, thanks to a “Double CPI” feature, the gaming mouse is able to ratchet up the sensitivity to an impressive 11,400 CPI, which makes navigating a six screen Eyefinity setup a breeze. Using SteelSeries ExactTech tracking customization technologies (ExactSens, ExactAccel, and ExactAim), Sensei’s laser sensor features a 10.8 megapixel image correlation at up to 12,000 frames per second (FPS), enabling it to track movements up to 150 inches per second.
All this tracking, macro support, and laser sensor horsepower demands a relatively beefy processor. While these instructions could be passed to the CPU for processing, having a dedicated chip on the mouse to process the sensor data and pass the coordinate data to the system can lower lag (or at least that’s SteelSeries’ goal). That requirement for computing time is where the 32-bit ARM processor comes into play. Specifically, the company states that the processor enables advanced SteelSeries ExactTech calculations to be done on the mouse itself and configuration via the mouse’s LCD screen.
The Sensei is slated for launch in September with a price of $90. The numbers and hardware are certainly impressive; however, whether that hardware will make a noticeable improvement in gaming and daily usage over the competition remains to be seen. More photos and information on the new Sensei gaming mouse can be found here.
What do you think about the Sensei’s inclusion of ARM processor and LCD screen? Personally, while I am rather partial to (blue) LEDs, I can’t see myself using the LCD screen or other gamer-oriented features.

Tagged: sandy bridge-e, processor, Intel, cpu
It seems as though intl is running into a slew of snags as they attempt to push out their Sandy Bridge-E processors and their accompanying X79 chipset motherboards. While it was previously thought that the Sandy Bridge-E processors would not be available until at least Janruary 2012, VR-Zone is reporting that the CPUs may actually be out in time for Christmas this year; however, they will have a reduced feature set. The X79 chipset that powers the Sandy Bridge-E processors will also be released with a reduced feature set. While Intel may reintroduce the removed features in later iterations of the silicon, the first run components will have PCI-Express 3.0 and four SATA/SAS 6Gbps ports removed. Further, Intel is waiting an extra CPU revision until it begins shipping the procesors out to board partners for their testing; the C-1 stepping instead of the C-0.
In the case of PCI-E 3.0 support, Intel has had trouble testing their engineering silicon with PCI-E 3.0 cards and is not confident enough to integrate it into their production chips at this time. due to the lack of widely available PCI-E 3.0 add-in cards, support for the standard is not that large of a loss in the short twrm but will certainly affect the component's future proofing value. The removal of the SATA ports is due to issues with storage that have yet to be detailed.
While new technology is always welcome, one cant help but feel that delaying the new processors and motherboards until the silicon is ready (and containing the planned features) may be better for consumers. The board and investors likely do not agree, however. In any case, Sandy Bridge-E and X79 are coming, it is just a question of how they come.
Asus today launched a new AMD focused F1A75 motherboard series, which the company claims is designed to optimize the performance of AMD’s Llano APUs. Equipped with such Asus features as Dual Intelligent Processors 2 (DIP2), DIGI+ Voltage Regulator Modules, auto-overclocking features, and a UEFI BIOS the new motherboards are packed with features and ready to be paired with a socket FM1 AMD processor thanks to the A75 chipset.
The most noticeable end-user feature in the new motherboard series will be the UEFI BIOS which does away with the old-school DOS look in favor of a sleek graphical interface that can be navigated via a touchscreen or a mouse (in addition to the obligatory keyboard input). Further, beyond the EZ mode and auto-tuning functions, it will allow overclockers to enter an Advanced mode to tweak their settings to get the highest overclock possible, and then save screen captures to a thumb drive by pressing the F12 key.
More specifically, the F1A75-V EVO model features the FM1 processor socket as well as two PCI-Express x8 slots for CrossFireX support in addition to native support for USB 3.0 and SATA 6Gbps standards.
The new boards should be available shortly at your favorite retailer(s). Be sure to stay tuned to PC Perspective for Llano desktop APU benchmarks.

Tagged: ulv, sandy bridge, Intel, cpu, celeron
According to Maximum PC, Intel recently revamped its official price list by adding four new ULV (ultra-low-voltage chips generally found in ultraportable notebooks) processors. The new additions feature three Sandy Bridge based chips and one Intel Celeron processor. The three new Sandy Bridge ULV CPUs include the dual core hyperthreaded Core i5 2557M with 3 MB cache running at 1.7 GHz, Core i7 2637M with 4 MB cache running at 1.7GHz, and the Core i7 2677M at 1.8 GHz with 4 MB cache. Utilizing Turbo Boost, the chips are able to reach 2.7 GHz, 2.8 GHz, and 2.9 GHz respectively. Further, the new Celeron ULV is the dual core Celeron 847 processor with 2 MB cache running at 1.1 GHZ.
The Core i5 2557M carries a pricetag of $250, while the Core i7 2637M goes for $289, and the Core i7 2677M has an MSRP of $317. You can see the entire price list here. The new Sandy Bridge based ULV processors are able to Turbo Boost from between 1.0 and 1.1 GHz depending on model, which should provide plenty of power for mobile devices while sipping battery power with a TDP (themal design power) of only 17 watts.

Tagged: x79, rumor, lga 2011, lga 1366, Intel, cpu
Xbit Labs recently detailed a new rumor concerning Intel’s upcoming X79 chipset. According to a leaked document viewed by them, X79 will support both Intel’s current and upcoming high end processors sockets in the form of LGA 1366 and LGA 2011. What this means for the end user is that they will be able to purchase a x79 based motherboard that will support either Nehalem or Sandy Bridge-E processors, unless motherboard manufacturers decide to splurge and include both sockets on one board like the Asus’ concept board shown at Computex 2011. This means that while DIY enthusiasts and gamers are not likely to use these motherboards as an upgrade path to Sandy Bridge (as a CPU upgrade would likely still necessitate a motherboard upgrade due to both sockets not being physically present), IT departments will likely appreciate the continued support of the older 1366 processors on new motherboards as it will make replacement parts easy to find for high end 1366 based workstations.
On the other hand, manufacturers will benefit the most from the X79 chipset supporting multiple sockets, and thus reducing costs. This cost reduction may then allow for cheaper end-user costs.
Intel itself is planning to manufacture two X79 motherboards named the DX79SI and DX79TO, will each support LGA 1366 and LGA 2011 respectively. Xbit Labs reports that the DX79SI board is planned to be a feature packed LGA 2011, no-compromise affair, with support for up to 64GB of RAM (eight DIMM slots), three PCI-E 3.0 slots for multi-GPU configurations, 12 SATA (six SATA 3 6GB/s, six SATA 2 3GB/s) ports, four USB 3.0, 14 USB 2.0, 8-channel audio, Wifi and Bluetooth, and two Gigabit Ethernet connections.
In contrast, the DX79TO will feature a LGA 1366 socket, and brings two PCI-E 2.0 x16 slots, 8 SATA connectors (likely four SATA 3, four SATA 2), 2 USB 3.0, 6-channel audio, a single Gigabit Ethernet connection, and DDR3 memory support (there are no details on the exact DIMM configuration supported yet).
By lowering the cost of supporting two high-end CPU lines and platforms, Intel, motherboard manufacturers, and consumers likely have a win-win-win situation, providing that the rumor comes to fruition.
