AMD FX-8150 Processor Gets Previewed and Benchmarked

Just a few more days are left until AMD will make official its highly anticipated FX-Series of desktop processors, and the company's flagship CPU based on the Bulldozer architecture, the FX-8150, was just put through a series of extensive benchmarks that compare its performance with that of the Core i7-2600K.

The FX-8150 is the most powerful of the three FX-Series processors AMD plans to launch and it includes four Bullodzer modules for a total of eight processing cores.

These are paired together with 8MB of Level 3 cache as well as with 8MB of L2 cache memory and the CPU also packs a dual-channel DDR3 memory controller supporting speeds up to 1866MHz.

AMD has set the base clock speed of the FX-8150 at 3.6GHz, but when less than half of the cores use the Turbo Core technology can raise its operating frequency up to 4.2GHz.

In comparison, the Core i7-2600K features quad processing cores with Hyper-Threading support, also 8MB of Level 3 cache memory and a 3.4GHz base clock speed with a 3.8GHz maximum Turbo.

Despite the higher clock speed and core count of the FX-8150, the AMD processor seems to be no match in front of Intel's chip, which managed to outpace its competitor in all the benchmarks run by Lab 501.

This includes highly threaded applications like Handbrake of CineBench R11.5, which should have favored the eight-core AMD CPU.

Furthermore, the FX-8150 also loses in front of Intel's chip when it comes to power efficiency as it requires no less than 129W when running in full load compared to the 93W of its competitor.

Outside of the usual performance tests, the preview also investigated the overclocking potential of the FX-8150 and the maximum SuperPi stable frequency reached was 5066MHz. However, total system stability could be achieved unless this was dropped down to between 4700-4800MHz.

AMD will release the FX-Series processors on October 12, and the FX-8150 is going to be priced at $245 US, about 182 Euros, which makes it $72 cheaper than Intel's Core i7-2600K.
