唔知技術方面係點...

但係以exclsuive cache?麍[構, K7/K8?餫2 latency & bandwidth本身已經比Intel差好多. 如果將L2做到好似Intel 咁大?儭, cache performance估計會好難睇下.

...

L2 latency係有得救, 不過Intel做得好d咁解

我係指exclusive cache inherent 嘅 latency比inclusive架構高...

但係未計L1 cache的速度 / 大細wor

在exclusive cache入面, L1 cache的速度重要性高於inclusive cache的L1 cache速度.

況且K8的L2 cache latency同Core Arch.的L2 cache latency其實差唔多
