AMD New processor Architecture "bulldozer" performance improvement 50%

While the entire industry is looking forward to AMD's new processor architecture "bulldozer" (bulldozer), it is expected to bring a performance explosion to compete against Intel, but although the bulldozer architecture is distinctive, the range of performance improvements appears to be limited.

AMD Server and Workstation products http://www.aliyun.com/zixun/aggregation/32064.html "> Marketing director John Fruehe said in an official blog:" From a performance perspective, If you compare the current 12 core Opteron 6100 series processors (code-named Magny) of the 16 core Interlagos (Interlagos) kernel, we estimate that the additional 33% cores will lead to a maximum of 50% performance improvements for our customers. ”

By conversion, the single core performance of the bulldozer architecture will only increase by 12.5% (should be at the same frequency). If that's the case, bulldozer architecture processors don't say that the next generation of Sandy Bridge, which Intel is about to sync with, is hard to win in the face of existing products.

Earlier on the AMD next-generation bulldozer processor information, today we do a brief collation, I believe many friends of the new architecture have placed great expectations. The first processor code based on the bulldozer "bulldozer" microprocessor architecture is Zambezi, which will be equipped with 2 separate ALU pipelining clusters, each with 4 pipelines, supporting multi-threaded technology, 2 128-bit Fmac floating-point units, shared L2, L3 cache, Integrated with memory controller. AMD also indicates that the new processor will support new and innovative power management technologies.

AMD Bulldozer cluster architecture

Above is a single bulldozer core, which takes note of 2 separate ALU pipelining clusters, each with 4 pipelines, all equipped with a unique L1 data cache, and a single FP cluster with 2 alu clusters. The Phenom II Core has an ALU pipeline cluster of 4 pipelines, but the bulldozer core is equipped with 2 clusters.
