Core i7 Extreme Overclocking with LN2

SANDRA and Cinebench Testing

To see what this insane setup is capable of, we ran a series of benchmarks to show just how powerful the platform is running at maximum overclocks. The first set of tests measure CPU performance and on the next page, we throw a couple of graphics benchmarks into the mix. We did our best to run the tests as close to 5GHz as possible, but we did lower the CPU overclock whenever we came across instability. 

SiSoft SANDRA 2009
Synthetic CPU Benchmark

We began our testing with SiSoftware's SANDRA, which stands for System ANalyzer, Diagnostic and Reporting Assistant. We ran the built-in Processor Arithmetic test at both stock and overclocked CPU frequencies.

4.83GHz and Stable - Click for High Res.

Even with a massive overclock, we were still surprised at the performance increase we saw with SANDRA. The 4.83GHz processor scored about 45% higher than the stock clocked 975 in both Drystone and Whetstone benchmarks, which is directly proportional to our clock speed increase of course

Cinebench R10
3D Rendering

Cinebench R10 is an OpenGL 3D rendering performance test based on Cinema 4D from Maxon. Cinema 4D is a 3D rendering and animation tool suite used by 3D animation houses and producers like Sony Animation and many others.  It's very demanding of system processor resources and is an excellent gauge of pure computational throughput.

Cinebench is torturous - 4.8GHz realized (click for high res)

The 4.8GHz overclock shines bright during the Cinebench benchmark. We hit jaw dropping 6879 single threaded and 27373 multi-threaded CPU scores, a massive improvement over stock 3.33GHz scores of 4800 and 19014; about a 44% gainer which is also pretty sweet.
