Nvidia today announced the GeForce GTX 275 GPU, which the company claims is the highest performing GPU in the $230 to $250 price tier. As the name suggests, the GTX 275 nestles in between the GTX 260 and GTX 285, fleshing out the company's mid-range graphics line.
Build around the GT200 architecture, the GTX 275 sports 240 processor cores racing along at 1,404MHz, 80 texture processing units, and 895MB of GDDR3 video memory clocked at 1,134MHz on a 448-bit bus. The reference design calls for the GPU to run 634MHz. The end result is a videocard that, according to Nvidia, will best ATI's HD 4890 by 10 to 20 percent.
Nvidia also announced its new GeForce Power Pack #3. Included with the new Power Pack are three new PhysX-accelerated apps and two new CUDA-accelerated programs.
The GeForce GTX 275 will be available globally on or before April 14 in both standard and overclocked versions from the usual suspects (Asus, BFG, EVGA, Gigabyte, MSI, XFX, and more).
Integrated-circuit design is currently based on three fundamental elements: the resistor, the capacitor, and the inductor. A fourth element was described and named in 1971 by Leon Chua, a professor at the University of California, Berkeley’s Electrical Engineering and Computer Sciences Department, but researchers at HP Labs didn’t prove its existence until April 2008. This fourth element—the memristor (short for memory resistor)—has properties that cannot be reproduced through any combination of the other three elements.
Chua first theorized the memristor’s existence based on symmetry. There are four fundamental circuit variables—current, voltage, charge, and flux (changes in voltage), but until now, relationships had been defined for only three of those variables: A resistor opposes the flow of an electric current, so it relates voltage to current; a capacitor stores energy in an electric field between two conductors, so it relates charge to voltage; and an inductor stores energy in a magnetic field created by the electrical current running through it, so it relates flux to current. Chua believed that there must be an element that relates charge to flux, and he dubbed this undiscovered element the memristor because it would “remember” changes in the current passing through it by changing its resistance.
My roommate, with my help, built a brand-new PC worthy of mention in your magazine; it has a Q6600, 4GB of DDR2/1066, an ATI Radeon 4850 GPU, and a DFI P45-T2RS motherboard. After installing his student copy of Windows Vista x64 and some of his favorite programs, I advised him to run CPU-Z to ensure that the motherboard had set everything correctly, as I didn’t really want him to have to dive into the BIOS unnecessarily. CPU-Z reported that his RAM was cruising along at DDR2/800.
He has a 1,066MHz front-side bus, so the RAM timing was unusual, especially since the board is certified for DDR2/1066. We checked the BIOS and found that we cannot set that frequency without overclocking, which causes the machine to become unstable. We decided that the problem is the BIOS and discovered that DDR2/1066 is supported only in the latest BIOS—but DFI’s BIOS update utility doesn’t work with Vista x64! Neither of us owns a floppy drive anymore, so we thought we might try booting from a USB drive, but we can’t find any Vista 64 capable tools for creating that, either. What should we do to update the BIOS?
Super Talent recently announced their latest SSD development with a new patented product called the RAIDDrive. This fancy new piece of tech promises to increase the performance and capacity that slot based storage solutions currently offer, by boosting the ceiling up to 2TB.
The RAIDDrive is currently in three different flavors: the RAIDDrive ES, the RAIDDrive WS and the RAIDDrive GS. The ES is aimed at enterprise servers that will perform intensive applications, such as database transaction processing, business intelligence and virtualization. The WS is directed at workstation use for animation, video editing, oil/gas exploration and CAD. The GS is meant for gamers looking for a (much) faster IO subsystem.
All of these drives connect through PCI-E 2.0 x8, and deliver read speeds of up to 1.2GB/s, and sequential write speeds of up to 1.3GB/s. No word yet on pricing or availability, but as with the last drive of this caliber, chances are good that it’ll cost about as much as a car. No joke.
It wasn’t long ago that MSI announced their X-Slim notebooks, but we’ve finally got some solid information as to what will be under the hood, along with some additional information on the latest generation of Wind netbooks.
The new generation of MSI Wind U123 netbooks will sport a 10.2-inch screen, a 1.66GHz Atom N280 CPU, 1GB DDR2 RAM, a 160GB HDD, a built-in TV tuner and the choice between a 6 and 9-cell battery.
As for the X-Slims, the X340 (which will start at about $1,000) will be one of the first machines to feature Intel’s new CULV platform (which is reported to only use one-sixth the power of a regular mobile CPU), and will come with a 13.4-inch 1366x768 screen, Intel GMA4500MHD graphics, up to 4GB of DDR2 RAM, a 320GB HDD and 802.11b/g/n.
As for the X320, it’ll come with a notably less powerful 1.6GHz Atom Z530 processor, the same size screen, Intel GMA500 graphics, up to 2GB of DDR2 RAM, a 250GB HDD and along with the 802.11b/g/n wireless, will have an optional 3G/WiMAX module.
No specifics yet on pricing for any of these machines, but given MSI’s past there’s a good chance that it’ll be reasonable.
According to IC3, they received 275,284 complaints last year (compared to the 206,884 in 2007). They were able to move 72,940 of these on to federal, state and local law enforcement agencies.
Many of the referred complaints, which were caused by anything from online auction fraud to identity theft, cost consumers roughly $264.6 million, with the median dollar loss reaching about $931 per complaint.
So how you can you stay safe? Just be smart about how you compute on a daily basis. The report was careful to explain that 74 percent of the reported crimes were perpetrated through e-mail, with another 29 percent conducted through Web pages. Watch yourself out there!
Just one week after Facebook deployed its latest design update, the social network is quietly rolling out a pair of beta services -- Facebook Premium and Facebook Classic -- to select users. Facebook Classic lets each user opt in to the Facebook design of his or her choice. From the pre-news feed design (circa 2006) to the single-page design used through much of 2008, beta users will be able to select the Facebook interface that they’re most comfortable with. In an official status update, Christopher Cox, Facebook’s Director of Product, cited the reasons behind this move, which he feels are "in line with the Facebook's intent to both respond to user feedback and adapt the product for different usage models and forward-looking feature opportunities".
Also in beta, and available to select users is the new Facebook Premium service.
At first glance, the Thermaltake SpinQ looks like nothing so much as a stack of bike gears with a fan mounted in the center. And that’s basically what it is—50 circular aluminum fins mounted around an 80mm fan connected to a copper exchanger. The cooler measures 4.8” wide by 3.54” deep by 5.98” high—about the same height and width as the Zalman CNPS9700LED, but a bit deeper. The SpinQ is, essentially, the high-rise counterpart to the horizontal sprawl of its stablemate, the Thermaltake DuOrb.
Unlike the DuOrb, with its two fans and jarring red-and-blue LED color scheme, the SpinQ keeps to one color, a soothing blue, and a single fan. And instead of the DuOrb’s retention system, which is sturdy but requires you to remove your motherboard, the SpinQ uses the same plastic mounting system as Intel’s stock coolers, so provided you don’t already have a retention plate from your previous cooler installed, all you have to do is snap the SpinQ onto the motherboard, tighten it, and go. Thermaltake definitely wins points for the SpinQ’s ease of installation.
Intel this week launched its new Xeon 5500 series, which were previously known as Nehalem-EP, along with a handful of new mobile Core 2 Duo chips built around the 45nm Penryn core. Following the release, Intel has posted an updated price list reflecting the new CPUs.
Pricing for the new Xeon chips range from $188 for the entry-level E5502 (1.86GHz, 4MB L2 cache, 80W) on up to $1,600 for the flagship W5580 (3.2GHz, 8MB L2 cache, 130W). A total of 12 new 45nm Xeons have been added in all, covering just about every price point.
On the mobile front, four new Core 2 mobile chips have been added, starting with the Core 2 Solo SU3500 (1.4GHz, 3MB L2 cache, 5.3W) for $262. Other chips include the Core 2 Duo SU9600 (1.6GHz, 3MB, 10W) for $289, Core 2 Duo SL9600 (2.13GHz, 6MB, 17W) for $316, and Core 2 Duo SP9600 (2.53GHz, 6MB, 25W) for $316.
We're not sure what to make of Moixa's 'Sphere' I/O interface device, for which the company was recently awarded a patent. Moixa describes the device as an "apple sized multi-touch sphere that can be used to display the world (e.g. Google Earth), browse web pages, or control interactive games." Sounds intriguing.
Moixa says the device also weighs about the same as an apple, and can be collapsed to be either used or stored in its second form. This could change, of course, as the concept remains in render form, just as Art.Lebedev's OLED keyboard did before a shipping product finally emerged.
"In the future, phones and portable computing devices reduce to input/output and power. Sphere reinvents the look and feel of the advanced portable device as we rely more on services, memory and mapping stored on the web," commented Simon Daniel, Moixa founder.
Anyone see this concept becoming an actual product? Hit the jump and post your thoughts.
