Euler 3D Fluid Dynamics

This fluid dynamics simulation is very CPU and memory intensive.  From the benchmark source website:

The benchmark testcase is the AGARD 445.6 aeroelastic test wing. The wing uses a NACA 65A004 airfoil section and has a panel aspect ratio of 1.65, a taper ratio of 0.66, and a 45 degree quarter-chord sweep angle. This AGARD wing was tested at the NASA Langley Research Center in the 16-foot Transonic Dynamics Tunnel and is a standard aeroelastic test case used for validation of unsteady, compressible CFD codes. Figure 1 shows the CFD predicted Mach contours for a freestream Mach number of 0.960.

The benchmark CFD grid contains 1.23 million tetrahedral elements and 223 thousand nodes. The benchmark executable advances the Mach 0.50 AGARD flow solution. Our benchmark score is reported as a CFD cycle frequency in Hertz.

It seems obvious that the Euler3D algorithm prefers the Intel-based architecture quite a bit over the AMD design as even when running in a four+ thread environment the Core i3-2100 is able to beat out the A8-3850 APU.  
 



Microsoft Image Composite Engine

This application takes any number of images and attempts to "stitch" them together to make a single panoramic image.

In this test we see the A8-3850 falling behind the Core i3-2100 by about 25%.


Hyper PI (Super PI)

From Wikipedia: Super PI is a computer program that calculates pi to a specified number of digits after the decimal point – up to a maximum of 32 million. It uses Gauss-Legendre algorithm and is a Windows port of the program used by Yasumasa Kanada in 1995 to compute Pi to 232 digits.

HyperPi is another program that just doesn’t run very well on the A8-3850 as the frequency and IPC are just greatly improved on the Intel Sandy Bridge CPU.
