Intel Shows Mystery Dual-Core Desktop Chip

Well, Intel did say - dismissively of course - that wasn&#39;t going to try to match AMD&#39;s little dual-core Opteron demo coup of last week and show off a dual-core Xeon at the Intel Developer Forum this week and - as good as its word - it didn&#39;t.

Intel is shipping a dual-core Celeron processor, the first low-end desktop processor from the company to ship with two cores.The 1.6GHz Celeron Dual-Core E1200 processor is based on Intel&#39;s Core microprocessor architecture and is manufactured using a 65-nanometer process. The chip has 512KB of cache and uses an 800MHz front-side bus to connect with main memory and other components inside the PC.Intel is selling the Celeron Dual-Core E1200 chips for $53 each, in quantities of 1,000 units.The release of the E1200 underscores how prevalent dual-core chips have become. The Celeron family is the low end of Intel&#39;s mainstream processor range, below the mid-range Pentium family and top-end Core 2 Duo and Core 2 Quad lines. The release of the Celeron E1200 means Intel now has multi-core processors in each of these product families.Intel already offers a range of dual-core chips in its Pentium line: the 1.6GHz Pentium Dual-Core E2140, 1.8GHz Pentium Dual-Core E2160, 2GHz Pentium Dual-Core E2180, and the 2.2GHz Pentium Dual-Core E2200. The Pentium Dual-Core chips are priced from $64 to $84, in 1,000 unit quantities,

(InfoWorld) - Following their march from standard processors to dual-core and quad-core designs in 2006, Intel researchers have built an 80-core chip that performs more than a teraflops (trillions of floating point operations per second) while using less electricity than a modern desktop PC chip. First described by Intel executivesÂ at a September trade show, the chip fits 80 cores onto a 275-square millimeter, fingernail-size chip and draws only 62 watts of power -- less than many modern desktop chips. The company has no plans to bring this "teraflops research chip" to market, but is using it to test new technologies such as high-bandwidth interconnects, energy management techniques, and a tile design method to build multicore chips, said Jerry Bautista, director of Intel's tera-scale research program. He spoke in a conference call with reporters on Friday before presenting technical details of the research at the ISSCC (Integrated Solid State Circuits Conference) trade show in San Francisco. Intel engineers are also using the chip to explore new forms of tera-scale computing, in which future users could process terabytes of data on their desktops to perform real-time speech recognition, multimedia data mining, photo-realistic gaming and artificial intelligence. Until now, that degree of computing performance has been available only to scientists and academics using machines like ASCI Red, the teraflops supercomputer built by Intel and its partners in 1996 for U.S. government researchers at Sandia National Labs, near Albuquerque, New Mexico. That system handled a comparable amount of computing as the new chip, but demanded an enormous 500 kilowatts of power and 500 kilowatts of cooling to run its nearly 10,000 Pentium Pro chips. Shrunk onto a single chip, that power would allow average consumers to use their PCs in new ways. They could use improved search functions on the vast amounts of digital media stored on home desktops, searching large photo archives for specific attributes such as all the shots where a certain person is smiling, or where that person is posing with a friend, Bautista said. Running at 3.16GHz, the new chip achieves 1.01 teraflops of computation -- an efficiency of 16 gigaflops per watt. It can run even faster, but loses efficiency at higher speeds, performing at 1.63 teraflops at 5.1 GHz and 1.81 teraflops at 5.7 GHz. The processor saves power by shunting idle cores into sleep mode, then instantly turning them on as they're needed. Each modular tile has its own router built alongside the core, creating a "network on a chip." Despite using such an efficient grid, the researchers found they could actually hurt performance by adding too many cores. Performance scaled up directly from two cores to four, eight and 16. But they found that computing performance began to drop with 32 and 64 cores. "If we simply added more than 16 cores, we would get diminishing returns, because the threads and data traffic would not be used properly, so the cores get in the way of each other. It's like having too many cooks in the kitchen," said Bautista. To solve the problem on the new chip, they used a hardware-based thread scheduler and faster on-chip memory caches, optimizing the way data flows from memory into each core. To improve the design, Intel researchers plan to add a layer of "3D stacked memory" under the chip to minimize the time and power required to feed the cores with data. Next, they will create a mega-chip that uses general purpose cores instead of the floating-point units used in the current design.

(InfoWorld) - IntelÂ launched a dual-core notebook chip for high-end users on Monday, continuing an effort toÂ defend its shareÂ of the fast-growing notebook PC market against Advanced Micro DevicesÂ (AMD). Intel is selling the new Core 2 Extreme X7800 processor to PC vendors now, and says it will reach store shelves within two weeks, boosting performance for the hard-core gamers and digital artists who now use notebooks powered by Intel's Core Duo T2600. The company encouraged vendors to push even faster performance by opening the chip's speed protection locks, allowing them to overclock the processor for even faster operation. Some video game fans seek top performance by running chips beyond their rated speed limits on desktop PCsÂ such asÂ Dell's XPS 720 series. The practice is less common on notebook PCs, which are usually optimized for the best battery endurance. By concentrating on notebooks, Intel is aiming at the sweet spot of the PC market. Vendors have seen sparse growth in desktop PC shipments in recent years, increasing by only single-digit percentages in 2005, 2006, and forecasts for 2007. But demand for notebooks in soaring, with global notebook shipments showing increases of 35.9 percent in 2005, 28.4 percent in 2006, and an estimated 25.3 percent in 2007, according to the analyst firm iSuppli. In May, Intel made another effort to push sales of its mobile chips byÂ launching its Santa Rosa bundleÂ of mobile processors and chipsets, an upgrade to its popular Centrino platform.Â AMD quickly respondedÂ by announcing later that month that it would use a new mobile processor called "Griffin" as the basis of a collection of processors and chip sets code-named Puma, expected to reach markets in the middle of 2008. Intel now hopes to regain the initiative by expanding its Core 2 Extreme brand from high-end desktops to high-end notebooks. It is selling the 2.6GHz Core 2 Extreme X7800 notebook chip for $851. Also on Monday, Intel announced five new desktop chips, led by the quad-core, 3.0GHz Core 2 Extreme QX6850, intended for game developers, and the 2.66GHz Core 2 Quad Q6700. Intel is selling those two chips for $999 and $530, respectively, priced in 1,000-unit quantities. Intel's new dual-core chips are all in the Core 2 Duo family, including the 3.0GHz E6850, for $266; the 2.66GHz E6750, for $183; and the 2.33GHz E6550, for $163. The company is shipping all the chips now, and expects vendors to bring them to markets in two weeks.
