Magma EB7R-x8 User Manual

             29  

Note that the maximum number of tracks is achieved with all PCIe cards 
inserted directly into the PC. Using the EB7 expansion chassis we note 
the difference in track counts is no larger than 20% compared to a 
scenario where all cards reside in the PC, taking up all available slots. 

Magma’s EB7 chassis can be used to add a high end PCI express video 
card to a PC system, server or laptop that was not equipped with such a 
device for various reasons: cost , physical space, heat dissipation etc. 

A question then arises as to how good 
of a performance we can get by 
utilizing the expanded PCIe bus and 
high end video card . In order to obtain 
a definitive answer we turn to 
Futuremark’s 3DMark® benchmarking 
software. Since its introduction at the 
turn of the millennium, 3DMark® has 
become the de-facto standard in Video 
card performance testing and 
evaluation.  

  

The 3DMark® suite is optimized to 
work under Windows Vista and 
supports the latest DirectX and 
derivative  3D  multimedia  technologies.                                     
In this environment, a low-profile Dell 
PowerEdge server (with a built-in ATI 
ES1000 video chipset) was tested  with 
various external PCIe video cards.
