Late last month (August 2012), we reported that the specifications of the AMD FX-8350 Vishera processor had been discovered. Now we are bringing you the results of a benchmark test conducted on the chip, in comparison to its predecessor, the FX-8150 Bulldozer.
The folks at OBR-Hardware are the ones that managed to pit the two 8-core units against one another, and they were quite thorough in their tests.
Cinebench R20 x64, Cinebench R11.5 x64, Fritz Chess, SuperPi 1M, x264 Benchmark – 720p and wPrime 32 are the names of the benchmarking suites.
The results vary, but the overall conclusion is that the AMD Vishera has a 10% better multi-threaded performance and 4-5% better single-thread performance.
Thus, the Piledriver architecture (which Vishera is based on) does come with some improvements, but they aren't all that legendary.
Fortunately, we can find hope in the fact that the Vishera herein tested, being an engineering sample, may be further improved before it reaches retail, even if it already is in the OR-C0 revision, which is bound to ship in its current form.
The system that the processors were tested on used an AM3+ Crosshair V Formula-Z from ASUS, plus a Noctua heatsink, Kingston 2,333 MHz DDR3 RAM (random access memory), the NVIDIA GeForce GTX 660 Ti graphics card and an Antec PSU.
And now, for the specs: the Bulldozer FX-8150 features a clock speed of 3.6 GHz and a Turbo Core frequency of 4.2 GHz, while the FX-8350 Vishera is a 4.0 GHz part with 4.2 GHz Turbo Core.
Since both are constructed on the 32nm manufacturing process, the advantage of the latter is, thus, owed solely to the Piledriver architecture. The higher base clock likely helped, but the top maximum speed was still the same, so the benchmarks probably weren't swayed by them much either way.
