AMD Readies New Opteron Processor For 1000MHz HT Bus
Advanced Micro Devices is projected to release its new chip for servers on Monday, the 14th of February. It is claimed that in addition to higher clock-speed the new Opteron will sport higher-speed HT bus as well as SSE3 technology.
Source: X-Bit LabsThe forthcoming AMD Opteron processor 252 will be clocked at 2.60GHz, will incorporate dual-channel PC3200 memory controller, 1MB of cache and SSE3 technology, something that only Intel Corp.’s chips have sported so far. The upcoming Opteron chip will also sport 1000MHz HyperTransport bus, a speed boost over contemporary AMD Opteron products with 800MHz HT bus, according to CNET News.com web-site. The new chip for servers and workstations will be produced using 90nm SOI process technology.
SSE3 is an instruction set found in Intel Pentium 4 processors code-named Prescott. SSE3 includes 13 new instructions developed for some specific tasks. While guidelines that allowed software makers to take advantage of the SSE3 emerged in mid-2003, actual programs that take advantage of the SSE3 today is not large.
Due to higher speed HT bus it is unclear whether AMD Opteron 252 and its possible derivatives – AMD Opteron 152 and 852 as well as higher-speed models – are drop-in compatible with existing infrastructure based on AMD8000-series of chips. AMD has consistently stated that its future Opteron products, including dual-core products, would be compatible with servers, workstations and mainboards build upon AMD8000-series logic that officially supports only 800MHz HyperTransport bus. AMD declined to comment on the current news-story.
