Benchmarks Real world tests of Core i7 3820 vs FX 8350
GeekBench (32-bit)
3D Mark 11 (Physics)
FX 8350 | by Legit Reviews (Oct, 2012)The FX-8350 also gave us some significant gains in 3DMark 11.
Cinebench R10 32-Bit
Core i7 3820 | by PCMag (Mar, 2012)But compared with the Core i7-3830K, you won’t see much of a difference in single-threaded applications: Both chips scored the same (1.53) in the CineBench R11.5 single-core test, showing where you can save money if you don’t heavily depend on highly threaded programs.
Cinebench R10 32-Bit (Single Core)
FX 8350 | by Ace-Rinehardt (Dec, 2012)CineBench rates it right at the level of 12 and 16 core processors, and when I give it a bit of OC power, it gets even higher than several servers.
Passmark
FX 8350 | by VinsanityD (Jul, 2013)My computer is very fast and got good marks on Passmark benchmark.
Passmark (Single Core)
FX 8350 | by Bighammerguynever gets above 50 degrees Celsius with a v6gt coolermaster oddly the cpu itself scores 15k on passmark but im sure someone will jump on this and say this is false so allow me to post the pic that shows this is true and then you can decide for yourself weather its worth it I believe it is.
