Benchmarks Real world tests of Core i7 3820 vs FX 8350
GeekBench (32-bit)
3D Mark 11 (Physics)
Core i7 3820 | by PCMag (Mar, 2012)On the Futuremark 3DMark 11 physics test, the Core i7-3820 dropped just below our threshold for smooth pliability, with a score of 8,679 and 27.6 frames per second (or fps) compared with 10,958 and 34.78fps for the Core i7-3930K and 11,509 and 36.54fps for the Core i7-3960X.
Cinebench R10 32-Bit
Core i7 3820 | by Tech Radar (Jan, 2012)Thanks to the extra couple of cores in the mid-range Sandy Bridge E chip, it takes a lead in the multi-threaded Cinebench rendering and X264 encoding tests.
Cinebench R10 32-Bit (Single Core)
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.
Passmark
FX 8350 | by Legit Reviews (Oct, 2012)Looking at the physics score we can see a difference of just under 900 points with the AMD FX-8350 taking the lead with 7325 3DMarks.
Passmark (Single Core)
FX 8350 | by Tech Radar (Nov, 2012)In Cinebench the AMD chip is only a little over 5 per cent slower, and in X264 there's less than a single per cent difference between them.
