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.

(InfoWorld) - AMD hopes to seize a larger share of the server chip market fromÂ its rival IntelÂ on Monday when it launches the Barcelona quad-core processor. AMD has been shipping the Quad-Core AMD Opteron chip to server vendors throughout August but will use its news conference in San Francisco to publicly announce those partnerships as well as prices and benchmark test results. The company plans to launch a 1.9GHz, 68-watt Barcelona chip that focuses on power efficiency, and a 2.0GHz, 95-watt version that focuses on price/performance, said Randy Allen, AMD's corporate vice president for the server and workstation division. In the fourth quarter, the company will follow that with a 2.3 GHz, 120-watt version for high-performance applications, and higher clock speeds for the first two chips. There is a lot at stake. After launching the original Opteron chip in 2003, the company enjoyed brisk demand as customers applauded the power-efficient performance of that 130-nanometer design process chip. But Intel soon got back in the fight as both companies built smaller, faster components, shrinking their chip scales to 90nm and adding a second core. AMD has endured disappointing results lately,Â posting losses in the hundreds of millions of dollars for recent quartersÂ and focusing its attention onÂ a merger with graphics chip maker ATI. At the same time, Intel claimed bragging rights to beating AMD to quad-core architecture andÂ 65nm scale chips with its ClovertownÂ server chip.Â Intel is also preparing to launch an even smaller-featured design in the fourth quarter with its 45nm Penryn chip. AMD says Barcelona is the answer to the Intel challenge. The chip is designed with all four cores on a single die as opposed to Intel's design of joining two dual-core Woodcrest Xeon chips, Allen said. Even more important, AMD upgraded each core from 64-bit floating point performance to 128-bit and retained its Direct Connect architecture and on-chip memory controller to avoid bottlenecks in data flow, he said. Thanks to that design, the new chip will provide better performance while using the same amount of power, he said. A customer could upgrade a Hewlett-Packard ProLiant DL 385 server from AMD's dual-core to quad-core Opteron and gain faster operation with the same power and cooling demands. "Clovertown will look very anemic, especially as we bring out new frequencies. Customers really don't buy nanometers. What they care about is performance and benchmarking," said Allen. "That Direct Connect architecture is very helpful with virtualization, running multiple OSes, and other applications pulling more data than can be held in on-chip memory." Despite those advantages, AMD has missed out on a spike in market demand driven by a need to upgrade to servers capable of performing virtualization, one analyst said. "A lot of people view this as six months late or more," said Doug Freedman, managing director for research at American Technology Research. "Expectations got ahead of themselves, and some people viewed this as a potential savior for AMD after their server share topped out at the end of last year going up against Intel's dual-die quad-core. Now the feeling is this launch isn't robust enough in terms of samples shipped, design wins, and the complete food chain." To recover, AMD will have to quickly increase its production and release faster versions of Barcelona to improve the chip's availability for a range of applications, Freedman said. Intel executives say they are pressing the lead. "We are very confident, at least on the DP [dual processor] side, that we will have leadership across most of the benchmarks versus Barcelona," said Adesh Gupta, regional platform architecture manager at Intel Asia-Pacific's Server Platforms Group. "There are a small percentage of benchmarks which are floating-point based where we know that they have an advantage and that's an area which we will see them talk about a lot.... If you look at the broader spectrum of applications at the enterprise, we have a significant lead today, and we believe we will have that lead with Clovertown, and once we have Harpertown with 45nm we will extend that lead further," Gupta said. However, some vendors say there is room in the market for both chips. Each processor has its own strengths, said Dell CEO Michael Dell in remarks to financial analysts at the Citigroup Technology Conference in New York on Wednesday. Based on early tests, Dell said, a server using Barcelona chips is faster at running floating-point applications than a computer with Intel's Clovertown chips, but Clovertown is faster than Barcelona at running integer instructions. "So depending on the applications you run, or your theories of computer science, one of those servers may be the best for you. It is simply unacceptable for a company of Dell's size to have only one of those choices," Dell said.

Ten months after Intel shipped its first quad-core server processor, Advanced Micro Devices finally released a quad-core Opteron that the upstart vendor hopes to use to recapture its momentum in the server market.

(InfoWorld) - Server makers are showing their first systems based on Advanced Micro Devices'Â upcoming quad-core Opteron chip, known as Barcelona. Barcelona servers from Supermicro Computer, Tyan Computer, and Uniwide TechnologiesÂ are on show at Taipei's annual Computex exhibition, which started Tuesday. The appearance of the chips, which are scheduled to ship later this year, signals they are getting closer to the market. Detailed specifications of the chips and servers on display were not immediately available. AMD is counting on Barcelona to boost its sales, and market share, in the face ofÂ heated competition from rival Intel. Barcelona, which is manufactured using a 65-nanometer process, contains four processor cores on a single piece of silicon. By comparison, Intel's quad-core chips use two pieces of silicon, each containing two cores, strapped together inside a single package. AMD claims its design gives Barcelona a significant boost in performance -- as much as 50 percent to 80 percent -- over its current Opteron chips. Uniwide and Supermicro are showing Barcelona systems that take advantage of a power-saving feature of the chip. Called Dual Dynamic Power Management, this allows the processor cores and on-chip memory controller to draw power separately, which AMD said allows better performance and power management. AMD also promised an easy upgrade path for existing Opteron customers. Motherboards that support current Opteron chips can be upgraded for the quad-core chips by updating the BIOS. Dual-core chips can then be swapped for quad-core Barcelona processors, which use the same chipsets and processor sockets. Tyan and Asustek ComputerÂ are among the companies making upgradeable motherboards.

After Intel CEO Paul Otellini bragged that Intel&#39;s Xeon chip was the most energy-efficient processor, Neal Nelson compared it to AMD&#39;s offering and found that Intel wasn&#39;t being exactly truthful.Recent tests by Neal Nelson &amp; Associates, an independent computer performance consulting firm, have reported that in 36 of the 57 cases tested an AMD Opteron-based server delivered better power efficiency than a comparably configured Intel Xeon-based server.The tests were performed on servers configured with 2, 4, 6 and 8 gigabytes of main memory at various transaction processing load levels. The results show that for certain configurations and at certain load levels the Intel Xeon based server was 2.4 to 11.7 percent more power efficient while in other cases the AMD Opteron based server was 9.2 to 23.1 percent more power efficient. In addition, when the systems were idle and waiting for transactions to process, the AMD server was 30.4 to 53.1 percent more power efficient.Power consumption while the servers are idle is particularly significant since many servers spend most of their time waiting for work. A November 16, 2006 press release from IBM quotes a report by the Robert Frances Group which states that on average servers in data centers are idle 80 to 85 percent of the time.The test results also showed that:-- Larger memory configurations deliver both higher throughput and better power efficiency;-- Intel&#39;s power efficiency advantages decrease as memory size increases;-- AMD&#39;s power efficiency advantages increase as memory size increases;-- For CPU-intensive workloads, the Xeon delivers 8.0 to 14.0 percent higher peak throughput;-- For primarily I/O intensive workloads the Opteron delivers 11.3 to 19.4 percent higher peak throughputNeal Nelson conducted these tests in response to a statement made by Intel CEO Paul Otellini in a July 18, 2007 analyst conference call. During that call Mr Otellini referred to Intel&#39;s &quot;lead in power efficiency&quot;. Neal Nelson decided to use his company&#39;s benchmark toolset to determine if Intel actually had a lead in power efficiency.In a somewhat dry comment, Neal Nelson said: &quot;It appears that Mr. Otellini&#39;s statement is inconsistent with the test results.&quot;The tests were not financed or sponsored by any company or group.Techworld is an InfoWorld affiliate.&#160;
