Cinebench 64-bit Preview
CINEBENCH is the free benchmarking tool for Windows and Mac OS based on the powerful 3D software CINEMA 4D. The tool is set to deliver accurate benchmarks by testing not only a computer's raw processing speed but also all other areas that affect system performance such as OpenGL, multithreading, multiprocessors and Intel's new HT Technology.

CINEBENCH includes render tasks that test the performance of up to 16 multiprocessors on the same computer as well as software-only shading tests and OpenGL shading tests on huge numbers of animated polygons that will push any computer to its limits.
Cinebench has always been one of my favorite benchmarks, and now it's available in native 64-bit! What could possibly be better?

In the software shading and single CPU render tests, the Xeons have a hard time pulling ahead of the old Opterons even with their obvious clock speed advantage. Crank up the threads and it's a different story as the Xeons simply run away with the win. But then again, if you figure out what a dual-core Opteron would do in this benchmark (even at a 2.0ghz clock speed), things start to look a bit different.

ScienceMark 2.0 64-bit
Science Mark 2.0 is an attempt to put the truth behind benchmarking. In an attempt to model real world demands and performance, SM2 is a suite of high-performance benchmarks that realistically stress system performance without architectural bias.

"MolDyn" - Science Mark 2.0 performs Molecular Dynamics Simulations. It has the flexibility of simulating any 5 noble gases, in 3 different crystallographic configurations, with variable numbers of atoms at a user specified temperature.

"Primordia" - Science Mark 2.0 computes the electronic orbitals for the atoms between Hydrogen and Promethium in the periodic table using a Restricted Hartree-Fock method. Primordia outputs the total all electron energy of the atom in addition to the kinetic and potential contributions. The user is allowed to specify different grids upon which the orbitals are determined.
After a few days watching task manager as a I ran and reran benchmarks on these three machines, I can honestly say that Sciencemark does not scale well beyond two threads. Even so, we've been using it for some time, and the numbers it provides are of particular interest as these types of workloads are run on high-end machines every day in "real-world" situations.

As you can see, the Opteron loves ScienceMark, and the extra cores/threads don't help the Xeons at all... No scaling.
