Pentium M on your Socket 478 platform: Part 2

Memory Bandwidth/Super Pi Testing

Memory Bandwidth Testing:

Everest 2.0 is a professional system information, diagnostics and benchmarking program for Win32 platforms. It extracts details of all components of the PC. It also tests the actual read and write speeds of your memory to give a fairly accurate look of true memory performance.

Results: It is fairly obvious that moving to dual channel memory does impact the Dothan for the better. On the i855GM chipset the Intel 770 was getting 3.2Gb/Sec and on the i865PE chipset it was observed getting 3.9Gb/Sec. An extra 700MB/Sec of bandwidth transfer should boost the performance levels of the Dothan processor.

Let’s take a look at the write bandwidth benchmark results now.

Results: Again as expected the ASUS i865PE motherboard with the CT-479 adapter performed better than the DFI i855GM motherboard. There was only a 378MB per second bandwidth difference shown by the data, but that is still a 58% increase in the write bandwidth thanks to moving over to dual channel.

SuperPi 1.1e :

SuperPi calculates the number Pi in this raw number crunching benchmark. The benchmark is fairly diverse and allows the user to change the number of digits of Pi that can be calculated. In this benchmark we ran SuperPi to 1 million places.

Results: Super Pi is a common benchmark used in the enthusiast community to judge system performance levels. The Intel 770 processor with the ASUS CT-479 adapter on the i865 board scored two seconds faster than the Intel 770 on the i855GM powered motherboard. When overclocked to 2.64GHz scores were able to reach 28 seconds.
