UPDATE: AMD has contacted X-bit labs claiming that it has not announced any simultaneous multi-threading technologies for Bulldozer processors. Still, there are other multi-threading implementations that may still be supported.
Advanced Micro Devices announced during Hot Chips conference that its next-generation code-named Bulldozer microprocessors will feature a multi-threading technology (SMT) which would be akin to Intel Corp.’s well-known HyperThreading.
AMD did not reveal many details about its multi-threading capability and only said that its Bulldozer processors would support it in 2011. Still, it is rather likely that AMD’s approach may be somewhat different compared to Intel’s HT and may even be of the same kind like Sun Microsystems’ simultaneous multi-threading feature than supports execution of four threads on one physical core.
“Bulldozer expands what has been the single-threaded nature of the AMD cores in a different fashion than Intel’s HyperThreading, said Pat Conway, a representative for AMD, reports EETimes web-site.
