Stressing them eight cores

The boot is on the CPU foot in the 7-Zip test. FX-8150 puts up a spirited showing here, where it bests all pre-noted CPUs. Eight-core processing finally showing its worth.

And while the FX-8150 is faster than the Phenom II X6 1100T in the multi-core CINEBENCH test, it needs two more cores and a higher per-core speed to beat out the erstwhile AMD champ.

Moving on to another stress-test, the eight cores of FX cannot beat the 1100T. Remember that FX has shared FP logic, which means that the eight cores aren't as independent and standalone as the 1100T's. Think of the range-topping CPU as a four-module processor rather than an eight-core beast here.

Yet FX does have a few tricks that Phenom II X6 doesn't. One of those is an improved instruction-set that takes in AVX and AES. The TrueCrypt encryption/decryption benchmark uses AES to good effect, as does the FX-8150. The doubling of an 1100T's score is the first time we see it distance the long-in-the-tooth Phenom II.

Put simply, if your application has been coded with AES extensions, FX-8150 is going to be fast.
