In the meantime, the module takes advantage of on-chip cache to reduce the pressure on the system buses.

同时，该设计还使用片上缓存方式，降低了系统总线的占用率。

Due to the latency difference between main memory and on-chip memory cache, POWER7 was designed with three levels of on-chip cache (see Figure 1).

由于主内存和芯片级内存缓存之间的延迟差别，POWER 7设计了三种级别的芯片级缓存机制(见图1)。

Remember that a CPU's cache is local (on-chip) memory that offers fast access over the system's memory.

记住CPU缓存是一个本地(片上)内存，提供了比系统内存更快的访问能力。

Likely to attract the most interest, however, is the top-end X7350 processor, which clocks in at 2.93GHz with 8MB of shared on-chip cache and a thermal design power rating (otherwise known as TDP) of 130 watts.

If that's all a bit too much for you, Intel's also rolled out two dual-core Tigertons, including 2.93GHz E7220 and the 2.4GHz E7210, each of which have a TDP of 80 watts and 8MB of shared on-chip cache.

The Duron also includes a larger on-chip memory cache than the K6-2, and AMD's Enhanced 3DNow instructions, designed to boost multimedia performance.
