Cinebench R10 64-bit

Download from: www.maxon.net

Cinebench R10 uses Maxon's Cinema 4D engine to render a photo-realistic scene of a shiny motorbike. The scene is highly complex, with reflections, ambient occlusion and procedural shaders so it gives a CPU a tough workout.

The test can be in run in single-threaded 1CPU mode or multi-threaded xCPU mode - just click the respective button. In this way, Cinebench R10 is useful for gauging the performance of each execution core of a CPU, as well as its overall performance.

As Cinema 4D is a real-world application - used on films such as Spider-Man, Star Wars among others - Cinebench R10 can be viewed as either a real-world benchmark or a theoretical one.

The single-threaded Cinebench test threw up an interesting result - the Phenom II X4 955 Black Edition and its 3.2GHz cores has roughly the same processing power as an Core i7-920's 2.66GHz core. That still means that the AMD architecture is doing less work per clock, but that if Intel hadn't implemented Hyper-Threading in Core i7 AMD's £195 CPU might have been almost as fast as Intel's £215 flagship-range CPU. But we digress...

The extra frequency of the 975 EE gives it the lead over the 965 EE either when both are at stock speed, or overclocked.

Even with the advantage of Hyper-Threading, the Core i7 920 is kept honest by the AMD 955 BE with only the 920 around 1,500 points (roughly 11 per cent) faster. Intel fanboys would've expected better from the 920.

Again, we see the 975 EE outpace the 965 EE by a fairly slender margin. Roughly 133MHz-worth, we'd say.
