Benchmarks: Cinebench 2003 64-bit, Maya

CINEBENCH 2003 64-bit Source: Cinebench

CINEBENCH 2003 is the free benchmarking tool for Windows and Mac OS based on the powerful 3D software CINEMA 4D RX. 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, multi threading, and multiprocessors. This version runs on 64-bit operating systems and processors only.

Higher scores are better.

The 64-bit version of Cinebench 2003 is a direct clash between our two newest CPUs. The Athlon64 X2 4800+ again comes out on top by an average of ~20%, but both CPUs post impressive results.

Maya - Rendertest Source: Alias

This rendering speed test for Maya 4 measures the time needed to render a single 3D scene with various lighting effects. The benchmark can use single or multiple processors and runs on both 32 and 64-bit versions of Windows.

Scores are measured in seconds; lower times are better.

Pentium D 840 64-bit 37

The Maya Rendertest supports either single or dual processors, allowing us to test the difference between the modes with a pair of dual-core CPUs. Moving to dual-core operation dropped the Intel Pentium D 840's render time considerably as it completed the benchmark in only 65% of the time required for the single-core test. Overclocking the processor also made a huge impact. 64-bit operation made no difference to the benchmark scores.

The Athlon64 X2 4800+ bested the Intel Pentium D 840 by 12-15 seconds in both tests, though the Intel processor was much more competitive when overclocked.
