We review and test the MSI Radeon HD 6850. Today the first customized Radeon HD 6850 makes an entry, it comes with custom cooling which definitely is a notch better. Now remember, the R6850 is clocked at 775 MHz right ? We'll take it towards 975 MHz today by applying some tweaks. The memory as well, standard you'll need to work with a 4000 MHz (effective data rate) memory clock frequency .. we'll take that to 4800 MHz on this product.

OCZ announced the RevoDrive X2 PCIe SSD, a blazing-fast storage device that uses the PCIe x4 interface to deliver transfer speeds of well over 700MB/s and random 4K write performance of 120,000 IOPS. The disk is available in 480GB to 960GB capacities and can be used as primary boot drive. OCZ provides a 3-year warranty and the specifications list a MTBF of 2 million hours.
OCZ Technology Group, Inc. (Nasdaq:OCZ), a leading provider of high-performance solid-state drives (SSDs) and memory modules for computing devices and systems, announces the launch of The RevoDrive X2 PCI-Express SSD, a follow-up to the successful launch of the first RevoDrive, with increased performance and capacity to serve high-performance computing consumers. The RevoDrive X2 upgrades the original architecture to deliver unprecedented speed up to 740MB/s and up to 120,000 IOPS, nearly triple the throughput of other high-end SATA-based solutions with a substantial reduction in the total cost of ownership (TCO) to the consumer. The product is available now through OCZ's global channel.
"The original OCZ RevoDrive SSD was designed to be the first high-performance, bootable PCIe SSD solution and has become a popular choice for demanding computing applications that require faster, more reliable storage," said Ryan Petersen, CEO of OCZ Technology. "Building on the success of the original design, we are excited to introduce the RevoDrive X2, which delivers both increased performance and capacity, making the RevoDrive X2 a viable option for a wide spectrum of applications that include professional graphic design, multimedia rendering, and workstations. With our recently announced new state-of-the-art SSD manufacturing facility in Taiwan, OCZ will continue to be at the forefront of developing and deploying game-changing solid state storage solutions."
The RevoDrive family gets its edge by eliminating the SATA II (3Gbps) bottleneck and leveraging a PCIe x4 interface to exploit the full potential of current flash technology. Like the original RevoDrive, the X2 uses an onboard RAID 0 design, but it also employs four SandForce-1200 controllers versus two in the original to maximize data access and bandwidth. In addition to promoting a faster, more responsive PC experience, the RevoDrive X2 is bootable, unlike competing PCIe solutions, to ensure quicker start-ups and load times compared to mechanical hard drives, a major plus for workstation PCs. The RevoDrive X2 thrives in a wide range of computing environments including demanding database and server applications as well as multi-media creation and management. Available in 100GB to 960GB capacities, the OCZ RevoDrive X2 provides ample room for data warehousing, applications, multimedia files, and operating systems. Additionally, the X2 provides the superior durability, energy efficiency, and reliability of SSDs.
Photo's appeared of what could be the GeForce GTX 580. The GTX 580 is unleashed next month to compete with the upcoming Raderon HD 6970 (Cayman). According to rumors the GTX 580 would be 20% faster then the GTX 480. The product would be based on the GF110 silicon which has 512 active shader processors. Furthermore you can expect a 512-bit memory bus.
Anyway, once we know more we'll be sure to inform you, have a peek at the two photo's.

Please refer to the CUDA Toolkit 3.2 Readiness Tech Brief for a summary of these changes.
Nokia Siemens Networks has become the latest to prove that existing copper phone line infrastructure is far from dead. It has demonstrated a DSL technology that can deliver "super-fast" broadband download speeds of up to a staggering 825Mbps (Megabits per second) over a distance of 400 metres, or 750Mbps over 500 metres.
The feat bests Chinese firm, Huawei, which last month used its SuperMIMO technology and "four twisted pairs" (i.e. technically four phone lines bonded together) to boost the maximum speed of DSL to 700Mbps (Megabits per second) over 400 meters (here).
Prior to that Alcatel-Lucent's research arm, Bell Labs, achieved a broadband DSL download speed of 300Mbps (here) via DSL Phantom Mode at identical distances of up to 400 meters (or 100Mbps at 1km). However this method only bonded two telephone lines together (i.e. 150Mbps each).
By contrast Nokia's solution also uses a similar Phantom DSL method, which creates a virtual (phantom) channel to supplement the two physical wires that are the standard configuration for many copper transmission lines. In theory this might make it more adaptable to UK networks, although BT already has a big contract with Huawei that might give their tech precedence.
Nokia's Head of its Broadband Access Business Line, Eduard Scheiterer, said:
"Laying down new optical fiber to the home remains costly, though it is capable of delivering very high speeds and is a definite solution for long-term bandwidth requirements. However, the innovative use of technologies such as phantom circuits helps operators provide an efficient last mile connectivity with existing copper wires."
It's certainly quite a leap above BT's current UK best of 40Mbps via Fibre to the Cabinet (FTTC). FTTC delivers a fast fibre optic cable to BT's street level cabinets, while the remaining connection (between cabinets and homes) is done using VDSL2 (similar to current ADSL broadband but faster over short distances) via existing copper cable. BT FTTC speeds are expected to be boosted to reach 'up to' 60Mbps in the not too distant future.
As a result Nokia claims that its new solution (hiX 562x/3x DSLAM) promises a bandwidth increase of 50-75% over existing bonded copper lines, which could prolong the life of copper networks and delay the need for full fibre optic rollout's (i.e. protecting the operator

The folks of Engadget published a couple of photos of a prototype of Sony Ericsson's elusive PlayStation Phone. The device is likely based on Android 3.0 "Gingerbread" and features a custom Sony Marketplace that enables you to purchase and download games.
The device snapped up top (and in our gallery below) is sporting a 1GHz Qualcomm MSM8655 (a chip similar to the one found in the G2, but 200MHz faster), 512MB of RAM, 1GB of ROM, and the screen is in the range of 3.7 to 4.1 inches. Looking almost identical to the mockup we hit you with this summer, the handset does indeed have a long touchpad in the center which is apparently multitouch, and you can see in the photos that it's still bearing those familiar PlayStation shoulder buttons. For Sony buffs, you'll be interested to know that there's no Memory Stick slot here, but there is support for microSD cards.
