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.

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.

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.
NVIDIA recently unveiled a new four core CPU for mobile devices at Mobile World Congress which promises to power 2560x1600, 300 DPI displays as well as enable realistic dynamic lighting and physics in mobile games, features that until recently were only possible in the realm of gaming laptops and desktops.
The quad core ARM CPU has been paired with a new 12 core GeForce graphics processing unit. The CPU alone is able to outperform the older Tegra 2 chip by close to 2x. With the additional GPU cores; however, NVIDIA has even more performance, and the ability to implement great looking games for mobile tablets and so called “super phones.”
At a resolution of 1280x800 (according to Engadget), the new Kal-El graphics demo shows off a new game featuring a glowing ball that acts as a truly dynamic light source in addition to realistic cloth physics. Using all four processing cores of the CPU allowed NVIDIA to implement cloth that reacts to the changing gravity of the game in a dynamic- and very realistic looking- manner. The mobile chip saw approximately 80% usage across all cores during the game demo. When NVIDIA disabled two of the CPU cores, the game became nearly unplayable, with the two remaining cores maxed out, the demo’s frame rate dropped to below 15 frames per second.
The new “Tegra Super Chip” will certainly allow mobile game developers to design immersive and realistic looking worlds as well as enhancing consumers’ ability to watch 1080p HD video with ease. The only drawback of the chip seems to be that battery technology is much slower to advance than transistor technology; therefore, it will be interesting to see how the new NVIDIA chip performs in that regard.
Recently, AMD launched two new AMD Embedded G-Series APUs (Accelerated Processing Units). The two new chips have a TDP rating of 5.5 and 6.4 watts, which represent a 39% improvement in power savings over the previous iterations. The 361mm² chip package is capable of being used in embedded systems without the need for a fan to cool it. The embedded chips include one or two low power x86 Bobcat processors and a discrete class DirectX 11 GPU on a single die.
AMD currently has three systems utilizing the new APUs, including a Pico-ITX form factor computer, a Qseven form factor computer, and a digital sign system. Buddy Broeker, the Director of Embedded Solutions for AMD stated that "today we take the ground-breaking AMD Fusion APU well below 7W TDP and shatter the accepted traditional threshold for across-the-board fanless enablement."
The two new chips are named the T40R and the T40E. The chips both run at 1.00GHz; however, the 6.4 watt TDP T40E is a dual core chip and the 5.5 watt TDP T40R is a single core variant. Both chips include an AMD Radeon 6250 GPU, a 64KB L1 cache, and a 512KB L2 cache per each CPU core. Further, the chips feature an integrated DDR3 memory controller that can support up to 667MHz solder-down SODIMMs or two DIMM slots. More details on the series as a whole can be found here.
Mobile and embedded processors continue to get smaller and faster. Have you seen any AMD powered embedded technology in your town?

If you have heard the term "bottleneck" when you have been describing your dream PC on the forums and wonder why people are referring to your CPU as the weak link when your GPU is so powerful that the CPU shouldn't have to do anything? Unfortunately it is not that simple and a powerful GPU can be held back by a CPU that can't keep up with it. Drop by Funky Kit for a look at bottlenecking by a serious overclocker who is quite used to overpowering CPUs.
"In the DIY computer world a lot of people are concerned about a video card (GPU) "bottlenecking" on a given CPU, or a given CPU bottlenecking a GPU. In this article I will explain what it is that they are talking about, as well as discussing whether or not it's worth being worried about. First off is the answer to the question "What is this bottlenecking you speak of?!"
