#Amd k10 vs k8 code
It should prevent programs from executing any data as a program and thus starting malicious code ( viruses, backdoors, etc.).Īs a further important innovation, in addition to the energy-saving Silicon on Insulator process, which was used for the first time in large-scale production, with Cool'n'Quiet, a power-saving technology that was previously only found in notebook CPUs. To "improve the security of a computer", AMD introduced the technology of the NX bit in the K8 generation. All CPUs of the K8 generation support MMX, Extended 3DNow! and SSE the Streaming SIMD Extensions 2 more modern steppings also the streaming SIMD extensions 3. For the low-price range, AMD initially developed pure 32-bit CPUs and marketed them under the names Sempron and Mobile Sempron. Not all K8 generation microprocessors support AMD64. “Pack” and the following “Decode”, which can be seen in the block diagram, are processed by these two additional pipeline stages. The pipelines were extended from 10 to 12 stages. In addition, the memory latencies have been significantly reduced because the memory controller has been relocated from the Northbridge to the processor itself. The K8 processors achieve the greater part of their increase in performance compared to the K7 processors through enlarged or improved caches as well as improvements to the preliminary stages of the processing units ( TLB, jump prediction, etc.).
