AMD FX-8150: Bulldozer on the bench table

In this article we'll show you a detailed analysis of the performance of the AMD FX-8150, top of the range of proposals based on the new Bulldozer architecture. The tests provide a full suite of tests in which the CPU will be compared to other proposals of the market, either by default or at different frequencies. We will also consider the impact of memory on performance, and the consumption as a function of voltage.

AMD Bulldozer press kit: FX-8150

The press kit sent by AMD is very rich and includes an Asus Crosshair Formula V, the FX-8150 CPU and a liquid-kit produced by Asetek branded AMD. Let's look at the CPU.

The AMD FX-8150, since it's Black Edition, is delivered in a very elegant metal box.

Inside you will find both the CPU and the air cooler that is absent in our case because was replaced with a liquid kit that will be presented later.

The CPU box is a black box with the logo printed on it. Opening it, there is, protected by a sponge on both sides, the CPU.

CPU-Z correctly reports the characteristics of this CPU: base clock of 200MHz, 18x multiplier for a default frequency of 3.6 GHz, 8 logical and physical cores.

In idle the frequency is reduced up to 1400MHz thanks to Cool'n quiet, lowering the operating voltage of our CPU from 1.248V to 0.984V.

The analysis of the tab that regard the cache we note 16KB per core for the L1 data cache and for the instructions we have a cache of 64KB per module. The associativity is 4-way for data cache and two-way for L 1 Instructions cache. Finally we have a 2MB L2 cache for each module and a shared L3 cache of 8MB (for a total of 16MB). Associativity for L2 and L3 is, respectively, 16 and 64-way.
