Cinebench 2003 & 3DMark05 - CPU Test

The Cinebench 2003 benchmark is an OpenGL 3D rendering performance test based on the commercially available Cinema 4D application.  This is a multithreaded, multi-processor aware benchmark that renders a single 3D scene and tracks the length of the entire process. The time it took each test system to render the entire scene is represented in the graph below (listed in seconds).

3D Modeling & Rendering Tests

We ran two sets of numbers here, one in single-thread mode and another in the benchmark's multithread mode.  Thanks to Hyper-Threading, the two single-core Petiums were able to complete in both tests, but the Athlon 64 3200+ can only execute the single-threaded test.

In the single-thread test, the Athlon 3200+ boasted the best score overall, beating out all three Pentium-class processors.  When comparing the three Pentiums in single-threaded testing, clock speed appears to be the name of the game once again.  When we shift over to multithreaded testing, the trend reversed completely.  Here, the Pentium D 820 simply crushed the Pentium 4 530J and 630.  While they did benefit some from Hyper-Threading, clearly two distinct cores are better than one as the Pentium D 820 virtually halved its single-thread results.

Futuremark 3DMark05 - CPU Test
Simulated DirectX Gaming Performance

FutureMark's 3DMark05 may be a DirectX-based benchmark, but it also offers the option to isolate testing to the CPU with its CPU module.  With some aspects of the software rendering supporting multithreaded instructions, 3DMark05 is an excellent test for quantifying CPU performance.

The results we see here reflect two scenarios.  The first is the Pentium D 820 taking the lead, as it is better equipped to handle multithreaded applications than the Pentium 630 and 530J with Hyper-Threading.  After that, clockspeed and L2 cache come into play, as L2 cache is the only real difference between the 630 and 530, while the 3200+ is the slowest processor of the bunch, according to 3DMark05, at least.  However, in terms of real-world gaming peformance, this may not be an accurate representation, as we'll show you in our gaming tests next.
