Preliminary Bench
The FX line of AMD is characterized, among other things, for operating frequencies, the number of cores and the fact that you have unlocked multipliers:
The preliminary bench which are shown below, are made by AMD and reported excellent performance for gaming and comparable performance to similarly priced Intel processors in the other benchmarks.
The tests are based on comparisons between AMD FX-8150 and Phenom X6 CPUs and INTEL CPUs from time to time specified. For consistency they chose to have 8GB of DDR3 1333 (even if it penalizes a little AMD FX 8150 CPUs, since they support memory up to 1866 MHz) and Windows 7 64-bit.
We begin with a comparison in situations of extreme resolutions with EyeFinity configuration and crossfire setup of HD6970 GPU, compared to a Core i5 2500K:
As you can see, the benefits are obvious and range from a low of 1% to a maximum of 22%.
The next test concerns Battlefield 3, comparing the AMD FX-8150, Phenom X6 and Intel 2500K, with a single HD 6950.
The improvement of AMD from one generation to another is a few FPS, however, enough to surpass even the Intel solution.
The last test gaming shows an extreme case: the use of top of the range CPU Intel Core i7-980X is not economically viable. To play most games with performance aligned or higher (with two exceptions), you need just an AMD FX 8150, saving, also $800:
Unfortunately lacking in this case the comparison with Sandy Bridge, direct competitor of Bulldozer.
Turning to the general purpose multi-threaded applications, the FX 8150 is still above 2500K ( with respect to which was normalized the graph) and generally aligned to 2600K, as shown in the following chart:
This slide is curiously different from what appeared a few days ago by rumors, with the values of FX and AMD 2600K exactly reversed. Even from these tests is nevertheless clear that the 8-core Bulldozer does not have performance comparable to a traditional 8-core, but show generally comparable performances to an Intel quad core with Hyper Threading.
Finally, the performance of the FX 8150 in Cinebench 11.5 64-bit at default (3.6GHz) and with an overclock to 4.8GHz:
This result indicates a good scalability in frequency, given by a performance increase of 31% compared with an increase of 33% of the clock, but the performance may be higher than that using memory of 1866 MHz even at default and finally you could get more performance in overclocking, increasing the frequency of the North Bridge and RAM. The result in absolute terms is not very encouraging for a CPU defined as having 8 cores.
