Subject: New G4's; ddr L3 cache significant or not?

Author: Will Singleton

Date: 08:44:00 01/28/02

The new Mac G4's came out today, 933mhz and 1ghz versions.  Question: this 2mb
of ddr L3 cache seems new.  Is that something that would significantly affect
integer performance?

Seems like the limiting factor is that old system bus again.

- 256K on-chip L2 cache running at processor speed
- 2MB DDR SDRAM L3 cache per processor, with up to 4GB per second throughput
- 133MHz system bus

        And I prefer the COSBI benchmark to the SPEC for several reasons. Dan Andersson 15:12:30 01/30/02
