On September 15th, Intel is expected to unveil its Xeon 7400 series Dunnington processor. What makes the server chip so special is it will be the first six-core processor, and likely the last Penryn to make a debut before the Nehalem microarchitecture takes over starting with the Core i7.
In another first, Dunnington will be the first Intel chip to sport a monolithic design, meaning all six cores will come on one slice of silicon. By contrast, the Core 2 Quad and four-core Xeon processors to date integrate two dual-core chips in a single package.
In addition to having six cores, the server market hopes to get big performance gains from the large 16MB of shared L3 cache. According to Intel senior vice president Pat Gelsinger, Sun Microsystems, Hewlett-Packard, and Dell will have product announcements related to the Xeon 7400 series in September.
For the AMD faithful not quite ready to step up to quad-core processing, AMD this week will start adding to its triple-core lineup. The new processors are based on AMD's Toliman core.
Phenom X3 8750 (2.5GHz, 95W)
Phenom X3 8550 (2.2GHz, 95W)
Phenom X3 8450e (2.1GHz, 65W)
Note the 'e' designation in the last processor, which will represent AMD's new lower wattage CPUs. The X3 8450e will be the first 65W tri-core out of the gates, followed by the Phenom X3 8250e (1.9GHz, 65W).
Astute readers might also notice that the Phenom X3 8750 is incorrectly clocked at 2.5GHz instead of 2.4GHz. That's not a typo, and according to TomsHardware, AMD plans to bump up the clockspeed by 100MHz. Not only that, but THW says the flagship tri-core CPU will sport an unlocked multiplier. Oddly enough, the site also reports AMD will release a Phenom X3 8850 clocked at 2.5GHz this October, with an unlocked version to follow in December. Go figure.
Has the time come to say goodbye to Abit? According to Hexus.net, the Taiwanese technology company and one-time enthusiast favorite will exit the motherboard market at the end of 2008.
"HEXUS.channel has confirmed this as fact from sources close to South East Asian distributors," the news and review site writes. "all of which will be notified by their Abit sales contacts from today onwards."
This isn't the first time Abit has been rumored to shut down or leave motherboards behind. Faced with bankruptcy, Abit was acquired by Taiwanese manufacturer Universal Scientific International (USI) back in May of 2006, and rumors this past year of Abit's demise swirled so strongly that the company issued a public denial.
Old school enthusiasts might recall Abit as one of the premier motherboard makers geared towards overclockers, a reputation which arguably took a hit when the company inked a deal to sell Fatal1ty branded products just months before the acquisition. For fans both old and new, Hexus reports Abill will honor RMAs and warranties for three years subsequently.
With Nehalem Core i7 nearing release, that means you can expect to find good deals on what's soon to be last generation hardware. But if you're looking to jump onto the Core 2 bandwagon on the cheap, you needn't wait for Core i7. Intel has updated its processor pricing list and added a new Celeron D model.
Taking its place as the second least expensive quad-core processor in Intel's lineup is the 45nm Q8200 priced at $224 (only the Q6600 costs less). Two and a quarter C-notes buys you four 2.33GHz cores running on a 1333MHz frontside-bus, but only 4MB of L2 cache.
For those content with two cores, the 45nm E5200 priced at $84 is now the least expensive Core 2 Duo processor in Intel's lineup. The E5200 comes clocked at 2.5GHz on an 800MHz frontside-bus with 2MB L2 cache.
And finally, making its debut is the Celeron D 450. Priced at a low $53, the 65nm 450 runs at 2.2GHz on an 800MHz frontside-bus with 512K of L2 cache.
The past few months we've watched SSDs gain momentum and attract the focus of both manufacturers and consumers. From larger capacities to faster performance, traditional hard drives suddenly find themselves on the verge of obsolesence. Or do they?
One of the biggest concerns surrounding SSDs continues to be long-term reliability, but there might even be a bigger stumbling block. Because many SSDs use industry-standard NAND flash chips designed for handheld gadgets, physical security becomes a potential issue. Jim Handy, director of semiconductor research and consulting firm Objective Analysis, points out there's nothing to prevent a hacker from unsoldering NAND chips from an SSD and extracting the data using a flash chip programmer. "There's really nothing sophisticated about this process," Handy said.
But that's not the only method. A hacker could use an ultraviolet laser to wipe out lock bits (encryption locks) from fuses on chip that secure SSDs. The data can then be read without any special software.
Is Jim Handy right to be concerned? Hit the jump to post your thoughts.
Intel fans be polite and stifle those snickers, but at the Games Convention in Leipzig, Germany, members of AwardFabrik.de managed to breach 4GHz on an AMD Phenom 9950 processor using liquid nitrogen cooling. Not without controversy, the feat failed to pass CPU-Z's validation.
Running at precisely 3952MHz, the team recorded a 19.954 second SuperPi 1M time, setting a new record for AMD processors. Other hardware used in the endeavor included a Foxconn A79-S motherboard and an OCZ 1KW power supply.
On a related side note, SuperPi may find itself being replaced as processor technology moves forward. While the world record for AMD CPUs now sits at just under 20 seconds, the record for an Intel processor is 7.14 seconds using an E8600 overclocked to 6376MHz, leaving little headroom for future record breaking attempts.
Some rumors just refuse to die, and one that refuses to stay buried is that Nvidia might be looking to enter the CPU market. On the surface, such a move would seem to make sense, as both AMD and Intel offer integrated CPU and GPU platforms. Speculation that Nvidia might develop a platform of its own has been particularly strong the past few months, and chairman Jen-Hsun Huang, a co-found of the company, only fueled the fire at his press conference on the opening day of NVISION, saying "we believe in x86...we believe in heterogeneous computing."
But while Huang has been hesitant to stomp on the rumor outright, Chris Malachowsky, another co-founder and senior vice president, went on the record with PC Pro as strongly denying the graphics chip maker would make such a move.
"That's not our business," Malachowsky said. "It's not our business to build a CPU. We're a visual computing company, and I think the reason we've survived the other 35 companies who were making graphics at the start is that we've stayed focused."
Malachowsky also pointed out Intel's marketshare dominance and financial strength in the CPU market as reasons why the Nvidia would be wise to steer clear.
Do you believe Malachowsky, or do you think the company will have a change of heart once Intel's Larrabee and AMD's Fusion start shipping?
Cnet posted an article saying that Nvidia is now offering what it calls "native" licensing of SLI to its partners and system builders. Native licensing will not require the use of Nvidia's nForce 200 bridge for the Core i7 and X58 motherboards. That is right, no chip. The difference between native and the nForce 200 is that native SLI allows for more “common configurations”. There were no details on what “common configurations” could mean.Only the boards certified by Nvidia will be Nvidia will be able to enable SLI.
Pure speculation on my part is that it might mean only dual cards in SLI, not 3 or more on the native solution.
We can hope that this is a sign of a thaw in relations befween Intel and Nvidia. Of course Nvidia board certification may not make motherboard manufactuers very happy at the prospect of another hoop to jump through.
In any case, we can at least be assured of having a helping of SLI with our Core i7.
While high end gaming cards like ATI's 4870 and Nvidia's GTX 280 hog all the spotlight, not everyone can afford (or needs) a top of the line card. Picking up the slack at the other end of the spectrum, Nvidia this week silently launched its entry-level 9400 GT graphics card.
The 9400 GT comes with 16 processor cores clocked at 1400MHz, a 550MHz graphics clock, and 512MB of memory chugging along at 400MHz. And thanks in part to the 128-bit bus, Nvidia claims the 9400 GT will run twice as fast as the comparable 8-series graphics card.
Nvidia has set the MSRP to $59, which buys support for DirectX 10, OpenGL 2.1, CUDA general-purpose parallel computing, and hardware HD video acceleration. A cursory glance around the web shows the 9400 GT as being a respectable overclocker, but even after pushing the clocks, it looks to be best suited for HTPC and light gaming duties.
Western Digital today announced the addition of 750GB and 1TB RE3 SATA hard drives to its enterprise lineup. The new drives boast a beefy 32MB cache buffer, enhanced vibration and shock tolerance, and what the company claims are "new electronics to increase performance approximately 20 percent and by as much as 60 percent in high-vibration environments."
Rounding out the feature-set are a several marketing buzzwords, including StableTrac (reduces system-induced vibration and stabilizes platters), dual processor (better processing power), RAFF technology (corrects linear and rotational vibrations), IntelliSeek technology (calculates optimum seek speeds to lower power consumption, noise, and vibration), and several more.
Western Digital has the MSRP on the 750GB and 1TB models at $199 and $249 respectively. The drives are available now and carry a five-year limited warranty.
