News around the WebMonday, June 27, 2005NVIDIA GeForce 7800 GTX Offers Unprecedented Performance. NVIDIA Takes King of the Hill Spot by Storm 7:18 pm | Yaroslav LyssenkoNVIDIA Corp. unveiled Wednesday its latest graphics processor GeForce 7800 GTX, the fastest visual processing unit ever built so far. NVIDIA GeForce 7800 GTX graphics chip features 24 pixel pipelines, 8 vertex pipelines and consists of more than 300 million transistors, providing unprecedented specifications. NVIDIA claims that their newest high-end offering is available for purchase in local shops on the day of the release which is very uncommon for top-of-the-line graphics cards offerings. As the proof of NVIDIAs’ statement a huge number of reviews are available shortly after the launch. “It’s taken three generations of revisions, augmentation, and massaging to get where we are, but the G70 is a testament to the potential the original NV30 design possessed. Using the knowledge gained from their experiences with NV3x and NV4x, the G70 is a very refined implementation of a well designed part. With a max of three times the MADD throughput, 50% more pixel pipes, and 33% more vertex power than 6800 Ultra, the GeForce 7800 GTX is a force with which to be reckoned. Putting this much processing power into a package that pulls less juice from the wall than a 6800 Ultra is quite a feat as well. The 300+ million transistors fabbed on a 110 nm process are quite capable, and NVIDIA’s compiler technology is finally mature to the point of handling all games with no shader replacement,” writes AnandTech. “The GeForce 7800 GTX’s GDDR3 memory is clocked at 600MHz (1.2GHz DDR) compared to the GeForce 6800 Ultra at 550MHz (1.1GHz DDR). As you can see, there isn’t a large raw increase in memory bandwidth. Even though the memory speeds are not much faster on the GeForce 7800 GTX compared to the GeForce 6800 Ultra, this is ok if games start to become limited by the shader performance. Now, on the other hand, if games do start throwing out larger textures and more generated pixels, then memory bandwidth will have a large impact. As we move into the future, 512MB video cards will have more space available to game content developers and they may choose to fill up this space with large textures, in which case a lot of memory bandwidth could help. For the time being, NVIDIA has decided to concentrate on raw shader performance,” speculates HardOCP. “In terms of features, the texture samplers attached to the fragment units are no different in G70, compared to NV40. However NVIDIA tell me that when fetching large textures in preparation for filtering, G70’s samplers have less latency pulling those textures out of memory. So while fragment programs always seek to hide texturing latency since it’s always much slower than a single cycle, there’s less latency to hide with G70. The samplers still perform single-cycle bilinear filtering, two-cycle trilinear and up to 16X anisotropic (128-tap) filtering, just like NV40 does,” claims Hexus.net. “The strongest aspect of the GeForce 7800 GTX is its pixel shader performance, like in Half-Life 2 and F.E.A.R. All games that emphasize the math1ematical capabilities of the graphics processor have shown a tremendous speed growth over the solutions of the previous generation, namely GeForce 6800 Ultra and RADEON X850 XT Platinum Edition,” concludes Alexey Stepin, X-bit labs’ graphics cards editor.
Microsoft Implements New Ways of Defying Spam. No Sender ID – No E-Mail Delivery 7:12 pm | Yaroslav LyssenkoWhile hacker attacks have always been one of the major threats in computer world, spam has become one of the biggest problems during the last decade. Junk mail is not only annoying, but companies have to spend millions of U.S. dollars on finding ways to decrease the spam message flow. According to Microsoft, 90% of all e-mails are spam, and not all of them are just advertising messages. Many junk mails carry spyware and different kind of harmware, which could threaten information security. This autumn, Microsoft is going to introduce to its Hotmail and MSN users a new way of filtering incoming messages. “Sometime around November, Hotmail and MSN will flag as potential spam those messages that do not have the tag to verify the sender. The move is meant to spur adoption of Sender ID,” said Craig Spiezle, Microsoft’s director in the technology care and safety group at the software maker. Sender ID is a specification for verifying the authenticity of e-mail by ensuring the validity of a server from which the e-mail came. But not all are fond of the idea of adopting this technology. “We think Microsoft is trying to strong-arm the industry into the adoption of an incomplete and not accepted standard,” said Dave Rand, chief technologist for Internet content security at security software company Trend Micro. “Microsoft’s move increases pressure on e-mail senders to adopt Sender ID. The technology requires Internet service providers, companies and other Internet domain holders to publish so-called SPF (Sender Policy Framework) records to identify their mail servers. About 1 million domains currently publish SPF records, Microsoft said. That’s far from the 71.4 million registered domains worldwide at the end of last year,” writes CNET News.com. AMD to Abandon Flash Memory Business. Spansion to be Spun Off, or Sold Off 7:07 pm | Yaroslav LyssenkoAdvanced Micro Devises flash business has historically been profitable and actually boosted the company’s revenue when its main – processor – business faced the doldrums: while AMD failed to deliver competitive and powerful microprocessors, the flash division could report significant sales. However, with Intel’s aggressive move to boost its flash memory market share, everything changed for AMD and now it has to make a decision about what to do with its non-profitable flash business. “In April, AMD Chief Executive Hector Ruiz announced the outfit would be taking its Spansion flash memory business public after the division dragged down what would otherwise have been solid earnings in the first three months of the year. While Spansion contributed 36.4% of AMD’s $1.2 billion sales in the quarter, which ended Mar. 27, it lost $110 million, leading to a net loss of $17.4 million. Spansion is a joint venture between AMD and Japanese electronics giant Fujitsu, with AMD holding the majority stake,” writes BusinessWeek Online. “Now the “You strip the business of cash right before a spin-off or a sell-off,” says Eric Ross, an analyst with investment firm ThinkEquity Partners in All Latest News |
