Dual Xeon Duo: What Good Is the L3 Cache?

PC Mark 2002

The additional L3 cache allows the dual Xeon to raise the relatively low memory performance (FSB speed, etc.). However, the P4 with 3.2 GHz and FSB800 is clearly in the lead in combination with the Intel 875P chipset. In this benchmark, the cache expansion causes an increase in memory performance of 6.9 percent.

Distributed Computing: SETI (Text Client 3.04)

In the SETI project, a 340 kB data packet is analyzed. The benchmark shows that the expanded cache of the dual Xeon system is very noticeable here. The performance increase is around 31.1 percent.
