Intel will unveil its "Tulsa" chip for multiprocessor servers Aug. 29, finally talking publicly about a chip it has been shipping to vendors for several weeks now.The company hopes the new chip will stem its loss of market share to the Opteron chip from Advanced Micro Devices. Server vendors including IBM and Dell have recently announced they would build more computers powered by Opteron instead of Intel\u2019s Xeon chips.Now Intel will add the new chip to its Xeon family of dual-core processors, slotting it above the Dempsey chip launched in May and Woodcrest chip launched in June. Tulsa is built with the same 65-nanometer process as those chips, but uses Intel\u2019s aging Netburst architecture and Truland platform, instead of the new Core Microarchitecture and Bensley platform.Tulsa is designed for servers with four or more processors, as an upgrade from Intel\u2019s current product in that space, the "Paxville-MP" chip, Intel engineers said in a presentation at the Hot Chips trade show this week in Palo Alto, Calif.Compared to that chip, Tulsa\u2019s cores run 13 percent faster while using 20 percent to 40 percent fewer watts. Intel builds each Tulsa chip by combining two 3.4GHz Pentium 4 cores on a single die, and will deliver both 150-watt and 95-watt versions. Technically, the main advantage of Tulsa is that it supports four threads per processor and has a large, 16MB cache, compared to Woodcrest\u2019s 4MB cache.Intel will target Tulsa at customers with demanding business applications such as\u00a0ERP and e-commerce, according to spokesman Nick Knupffer.-Ben Ames, IDG News Service (Boston Bureau)Related Links:\n\nOpteron Still Losing Out to Intel \u2018Woodcrest\u2019\n\nAMD Releases \u2018Rev F\u2019 Opteron Server ChipCheck out our CIO News Alerts and Tech Informer pages for more updated news coverage.
