Cinebench R11.5 Benchmarks Maxon Cinebench is a real-world test suite that assesses the computer's performance capabilities. Cinebench is based on Maxon's award-winning animation software, Cinema 4D, which is used extensively by studios and production houses worldwide for 3D content creation. Maxon software has been used in blockbuster movies such as Spider-Man, Star Wars, The Chronicles of Narnia and many more. Cinebench Release 11.5 includes the ability to more accurately test the industry's latest hardware, including systems with up to 64 processor threads and the testing environment better reflects the expectations of today's production demands. A more streamlined interface makes testing systems and reading results incredibly straightforward. The Cinebench R11.5 test scenario uses all of a system's processing power to render a photorealistic 3D scene, "No Keyframes" the viral animation by AixSponza. This scene makes use of various algorithms to stress all available processor cores. The OpenGL graphics card testing procedure uses a complex 3D scene depicting a car chase with which the performance of your graphics card in OpenGL mode is measured. During the benchmark tests the graphics card is evaluated by way of displaying an intricate scene that includes complex geometry, high-resolution textures, and a variety of effects to evaluate the performance across a variety of real-world scenarios.
Its readily apparent that the single core tests are right in line with the actual processer clock speed. The scores consistently reflect that throughout all of the Athlon-II processors. The i7-920, at 2.66GHz, doesn't follow that same trend, but we are focusing on the Athlon-II X4-640 and the other AMD processors here. When the Cinebench suite focuses on multi-core functionality, a good representation of their differences becomes apparent. At stock speeds, the Cinebench performance increase from the $35 more expensive X4-640 processor is right in line with the previous PCMark Vantage tests, at 29%. When overclocked, the two processors again follow the trend set by PCMark with the X4-640 outperforming the X3-445 by 30%. Again, these consistent results lend credit to the testing procedures used by both test suites.

Typing this on the internet - my kill a watt says my power usage is 73.9 watts this includes my power adaptors for my dsl router and my monitor + KVM + an ocz vertex2 (the 2 is very important) 50G ssd (the 50 is better than the 60 for reliability+longevit y sake).
When I turn on the speakers my pwrusage goes up to 76.6. When I add my printer idle it goes up to 85 watts.
After much testing I am now at stock speeds and just turned the cpu voltage down to 1.2 and the memory voltage down. The system is very stable at these speeds.
Thanks,
Bob
right now i got Athlon II x4 640, Asus M4A89TD PRO mainboard, ddr3 1600 2x2 GB RAM with 1,7-1,9V. instead of onboard GPU ive chosen Gigabyte's GF GTX 460 768 OC GPU - its high-end but doesnt use much power while iddle running.
as i can tell u dont have to decrease the multiplier. while cool n quiet turned on it decrease it automaticly down to x4 with 800 MHz core speed and 1,044 Voltage. the same goes with other componetns, the system reduce usage power and increase it when its needed (i.e. when ur playing games).
the only one thing u should remember - make sure to buy better quality(80+) PSU, like Seasonic or Tagan. with my config the 520W PSU runns perfectly
Regards
take a look at the cache of my Athlon II x4 640 :)
runs absolutely stable and well.
at 3 Ghz, not overclocked, i had the same test result with the Phenom II x4 940
actually... they are the same.
Hank, I think you should add that you not only increased the bus but hopefully reduced the HT multiplier etc as well. For those less experienced.
If I remember correctly things get troublesome above 2,5Ghz HT on that MB maybe could be fixed by changing volts here and there but yeah. And that BIOS is a hell :P I want numbers updated directly. For example if you increase the bus then change the multiplier it will not (in BIOS) show what you actually change to but what it would have been with default bus freq.
