Experimental Tests
Euler 3D Fluid DynamicsThis 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.
In Euler 3D the HyperThreaded nature of the Core i5-661 doesn’t seem to change much over a 2-threaded run of the test interestingly.
Microsoft Image Composite Engine
This application takes any number of images and attempts to “stitch” them together to make a single panoramic image.
These are VERY odd results for sure – the Lynnfield/Clarkdale testing seems to indicate that something in the P55/H57 chipset might be the difference maker here. It is likely then that the driver for the P55 controller on Windows 7 x64 RTM is more robust than that for the X58 chipset at this time and the Intel X25-M SSD was just more fully utilized there.
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 sees very similar performance results in the Core i5-661 processor compared to the competition.
