AMD Athlon 64 X2 3800+
Cinebench 2003 & 3DMark05
The Cinebench 2003 benchmark is an OpenGL 3D rendering performance test, based on the commercially available Cinema 4D application. This is a multi-threaded, 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).
The AMD CPUs outran the Pentium D 820 in both the single-threaded and multi-threaded Cinebench 2003 tests. Here, the Athlon 64 X2 3800+ was about 11.9% faster than the 2.8GHz Pentium D 820 in the single-threaded test, a difference of about 13 seconds. Only 7 seconds separated the X2 3800+ and Pentium D 820 in the multi-threaded test, but that was still a difference of about 12% in the X2 3800+'s favor.
3DMark05's built-in CPU test is a multi-threaded "gaming related" DirectX metric that's useful for comparing relative performance between similarly equipped systems. This test consists of two different 3D scenes that are generated with a software renderer, which is dependant on the host CPU's performance. This means that the calculations normally reserved for your 3D accelerator are instead sent to the central processor. The number of frames generated per second in each test are used to determine the final score.
Still nothing new to report with regard to the CPU performance test built into 3Dmark05. In this test, the Athlon 64 X2 3800+ was about 5% faster than the Pentium D 820, but nothing came close to AMD's flagship Athlon 64 x2 4800+, as expected.
