Dual-core - Wikipedia, the free encyclopedia If a dual-core processor has only 1 memory bus (which is often the case) the available memory bandwidth per core is half the one available in a dual-processor mono-core system. Typically enterprise server software is licensed per processor, and some software manufacturers feel that dual core processors, while a single CPU, should be treated as two processors and the customer should be charged for two licenses - one for each core. Proximity of two CPU cores on the same die have the advantage that the cache coherency circuitry can operate at a much higher clock rate than is possible if the signals have to travel off-chip, so combining equivalent CPUs on a single die significantly improves the performance of cache snoop operations. en.wikipedia.org /wiki/Dual-core   (1443 words)

Dual Core Processing: Over-simplified, demystified and explained. - Article - Short-Media AMD may be the first to take the limelight with their announcement of dual core AMD Opteron processors set to launch in mid-2005 but Intel and IBM are cueing up their dual core processors as well. A dual core Opteron that has two 2.4 GHz cores won't be classified as a 3800+, for example, or twice that at a 7600+. A dual core processor is between a single core processor and a dual processor system for architecture. www.short-media.com /review.php?r=261   (2645 words)

dual core - a Whatis.com definition - see also: multi-core processor, multi-core, dual core processor, dual core processing, multi-core processing A dual core set-up is somewhat comparable to having multiple, separate processors installed in the same computer, but because the two processors are actually plugged into the same socket, the connection between them is faster. Ideally, a dual core processor is nearly twice as powerful as a single core processor. In practice, performance gains are said to be about fifty percent: a dual core processor is likely to be about one-and-a-half times as powerful as a single core processor. whatis.techtarget.com /definition/0,,sid9_gci1015740,00.html?offer=trivia   (305 words)

PC Perspective - AMD Dual Core Processor Plans In contrast, Intel's initial method for dual core uses one die for each core on a single piece of silicon and an interconnect; if one die from their wafer line is bad, only a single core is wasted. All the dual core processors will be manufacturered on the 90nm process and will have a maximum power usage of 110w, only 6w higher than the current Athlon 64 FX processors. The main benefit for AMD using a single die for their dual core processors is that CPU cores will have one fewer circuit to pass through before accessing memory as opposed to the Intel designs. www.pcper.com /article.php?aid=122   (1158 words)

MacSlash More Information About Freescale's Dual Core G4s In fact, it is a little far-stretched to have a dual core processor that is pin compatible to processors that were not designed with dual cores in mind. A dual core G4 would be a good chip, because it has a very short pipline and a very good altivec implementation. a dual core, low power consumption and low heat emission chip, while undeniably attractive for a laptop, seems more suited to the current direction of supercomputing design. macslash.org /article.pl?sid=04/11/07/1721232   (502 words)

Athlon 64 and Opteron dual-core explained Two cores fighting for data from the main memory is nothing new, you can see exactly the same thing in older dual processor designs like the Xeon and the Athlon MP series. Having dual processor cores is a bit different. There are definite advantages to everything being on a single chip, most noticeably a reduction in latency, but it's unlikely that a system with one dual-core Opteron processor would ever manage to outpace a system with two single-core Opterons. www.theinquirer.net /?article=13344   (1117 words)

Geek.com Geek News - Dual-core Athlon 64 benchmarks leaked As for the dual core, they seem to actually be recognized as 2 separate CPUs by the OS, thereby showing up as CPU-1 and CPU-2, even though it is really "core-1" and "core-2" on the same die and using the same socket. It was a comparison of one dual core processor vs 2 single core processors in a single motherboard. I was impressed that the single core opteron was within 5% of the dual core athlon. www.geek.com /news/geeknews/2005Mar/gee20050314029588.htm   (3125 words)

PCWorld.com - AMD Sheds Light on Dual-Core Plans Frequency is still an important consideration when determining the overall performance of a system, but dual-core designs allow chip makers to conserve power with slower cores, says Barry Crume, a director with AMD's server and workstation business unit. The fastest single-core Opteron in AMD's product lineup runs at 2.4 GHz, and dual-core chips could be expected to run at least 1 GHz slower than similar single-core chips, he says. As the Sunnyvale, California, company adds multiple cores, it will need additional memory controllers to feed those cores with enough data to ensure the processor is running efficiently, Crume says. www.pcworld.com /news/article/0,aid,118078,00.asp   (468 words)

BetaNews AMD Demos Dual-Core Desktop Chip I think that a dual core amd chip will simply provide this same kind of smooth experience I have only a bit faster than with 2 seperate chips. Besides intel is just following the path traced by AMD with his DUAL CORE strategy (They have working in it for a long time), and for your information AMD is releasind their dual cores CPUs also this year. Intel has 80% of the market because of their ston marketing strategy, brainwashing non-advanced users (You are a perfect example of that), making them believe they have the best CPUs, and that the competition is not even near from them, which is obviously no true. www.betanews.com /article/AMD_Demos_DualCore_Desktop_Chip/1109191535   (1937 words)

© AMDboard.com - AMD Dual-Core & Multi-Core Processor Special - Part 1 The database vendor previously charged its enterprise software per processing core, meaning that a server running on a dual-core processor required two software licenses. "We are already the first manufacturer to bring dual core technology to the notebook,' said Bahr Mahony, the division marketing manager of AMD's mobile business segment, referring to the dual-core X2 inside That design creates some problems in that dual-core processors must have some logic that coordinates the actions of both cores, and those transistors have to go somewhere in an already small package, Douglas said. www.amdboard.com /dual_core.html   (1399 words)

PCWorld.com - AMD Clarifies Dual-Core Strategy The integrated memory controller and Hypertransport interconnect technology present in the AMD64 architecture allow AMD to produce a similar amount of performance from one dual-core chip as provided by a dual-processor server, Weber says. But those smaller leaky transistors have also made dual-core chips a more economically feasible proposition because manufacturers can now fit two smaller cores on a single die without decreasing the number of chips cut from a silicon wafer, says Dean McCarron, principal analyst with Mercury Research in Cave Creek, Arizona. The power leakage issues brought on by the switch to the 90-nanometer process generation has accelerated the shift to dual-core designs. www.pcworld.com /news/article/0,aid,116510,00.asp   (644 words)

X-bit labs - Articles - One Core Is Good. Two Cores Are Even Better! As a result, not only the two leading CPU developers, such as AMD and Intel, but also the VIA Company are planning to start introducing single-silicon dual-core CPUs in the upcoming year 2005. In fact, the idea to put two processor cores onto a single physical die is not that new in this industry. This trick allows single processor silicon to process two threads of calculations simultaneously, because the second virtual core uses processor resources undemanded by the first virtual processor. www.xbitlabs.com /articles/cpu/display/dual-core.html   (718 words)

Nvidia investigates dual core graphics It's interesting to note that Nvidia is doing this at IBM Fishkill, the factory that is also doing something about dual cores for AMD. I believe that this is the next "big thing" and the graphic industry will move towards it as soon as it becomes too expensive to make single core chips with many transistors inside. WE LEARNED that Nvidia is looking into making a dual die for a graphics chip. www.theinquirer.net /?article=21822   (277 words)

Intel Execs Run Down Dual-Core Roadmap The problem, according to Brookwood, is that Intel's dual-core chips share a common front-side bus, which means that both cores are forced through a common bottleneck. AMD, however, has said that is dual-core chips won't consume any more heat than a single-core part; Intel's Smith, on the other hand, said that the dual-core Extreme Edition parts will be designed for 120 watts, while the mainstream Pentium D systems will be designed with a 95-watt thermal envelope in mind. Interestingly, each core of the new EE chip will contain a single 1-Mbyte of cache; compared to the 2-Mbytes used by the current single-core version. www.extremetech.com /article2/0,1558,1771366,00.asp   (1335 words)

AMD to launch dual-core chips in 2005 InfoWorld News 2004-05-17 By Tom Krazit, IDG News Service An application with multiple software threads will run faster on a dual-core processor because the operating system can assign an individual thread to its own processor core. The Direct Connect architecture used to build the Opteron processor makes it easy for AMD's designers to place two processor cores on the same silicon die, said Ben Williams, vice president of AMD's server and workstation business. Multithreaded applications running on a single-core processor must wait for one thread to finish before another thread can be processed. www.infoworld.com /article/04/05/17/HNamddualcore_1.html   (1200 words)
