The notebooks we got for our tests were built using Core Duo T2400 and Intel Core 2 Duo T5600 processors, Yonah and Merom respectively, working at the same clock speed of 1.83GHz and equipped with 2MB of cache memory.
Both platforms were built around Intel 945PM Express (Calistoga) chipset with ICH7-M South Bridge. This chipset provides mobile platforms with high-performance dual-channel DDR2-667 SDRAM support, which is exactly what both our notebooks had. They were equipped with 1GB of this memory. Unfortunately, the Nanya memory used in ASUS platforms at this time works at the above mentioned frequency only with 5-5-5-15 timings.
ASUS F3J notebook family can come equipped with different discrete mobile graphics cards on ATI as well as Nvidia chips. The F3Ja notebook modification that we had featured ATI Mobility Radeon X1600 with 256MB of graphics memory that could be dynamically expanded to 512MB thanks to HyperMemory technology.
You can check out ASUS official website for the detailed notebook specifications. I would only like to specifically mention a few things that have direct influence on the performance. Since ASUS F3Ja notebooks are based on Centrino Duo platform, these mobile computers are equipped with the Intel PRO/Wireless 3945ABG network adapter with the PCI Express bus. They also featured Fujitsu MHV2120BH Serial ATA hard disk drives with 120GB storage capacity and 5,400rpm spindle rotation speed, as well as 8x DVD RW drives. Both notebooks were equipped with identical 4800 mAh batteries.
