1.1. Key Features and Benefits
1.1.1. VIA QuadCore /VIA Eden
™
X2 Processor
The VIA QuadCore is a 64-bit superscalar x86 quad core (Isaiah) processor
combine on two dies. It is based on advanced 40 nanometer process
technology packed into an ultra compact NanoBGA2 package measuring
21mm x 21mm. The VIA QuadCore processor delivers a superb performance
on multi-tasking, multimedia playback, productivity and internet browsing in a
low power budget.
The VIA Eden X2 is a 64-bit superscalar x86 dual core processor based on a
40 nanometer process technology. Packed into an ultra compact NanoBGA2
package (measuring 21mm x 21mm), it delivers an energy-efficient yet
powerful performance, with cool and quiet operation.
Note:
Note:Note:
Note:
For Windows 7 and Windows Server 2008 R2 users only:
If encounter the issue such as the operating system recognize the VIA Dual-Core CPU as two processors
instead of one processor with two cores. Download and install the hotfix released by Microsoft to
address this issue. The downloadable hotfix is available at http://support.microsoft.com/kb/2502664
http://support.microsoft.com/kb/2502664http://support.microsoft.com/kb/2502664
