AMD 將於 2011 年推出新架構的 CPU, 代號 "Bulldozer"

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.

It is interesting to note that earlier AMD did not consider SMT or other multi-threading implementation to be a viable feature. However, it did admit that simultaneous multi-threading is a necessary feature of the future generations of microprocessors that significantly boosts performance.

Bulldozer is the next-generation micro-architecture and processor design developed from the ground up by AMD. In fact, Bulldozer will be the first major redesign of AMD’s processor architecture singe 2003, when the firm launched its Athlon 64/Opteron (K8) processors. It is expected that the next-generation micro-processors will offer considerably higher performance than current-generation chips. AMD Bulldozer CPUs will also feature SSE5 instruction set.

The first desktop processor in the Bulldozer family is code-named Orochi and it has more than four cores, more than 8MB of cache and supports DDR3 memory. The Orochi chip will be made using 32nm process technology and is currently due in 2011. Server processors powered by Bulldozer micro-architecture are code-named Valencia and Interlagos. Those chips will have six to eight and twelve to sixteen processing engines.

AMD終於都有SMT
值得期待

1年 K10.5
2011 先換AM3+

SMT 係咩黎?

TOP

multi-threading technology (SMT)=多執行緒/多线程
Intel自己就叫HyperThreading=超執行緒

簡單黎講就係單核U扮雙核。

2010 Q1 intel都出6核啦喎

TOP

2011年?? intel都唔知發展成點,分分鐘celeron都有ht
到時推土機唔會令人期待

AMD話32nm會玩8-core

K10都有6-core啦
