In the past years, AMD CPU performance hasnít been revolute.
Since 2006, first time K8 performance crossed over by Core 2 Duo, they started to focus on multi-core and parity price.
For entry or mainstream PC users, itís good news.
During that time, AMD high end product lost the performance strength, they only could move to mid-end market.
After Core i launched, the single core performance gap was even bigger. Multi-core became main product strategy for AMD.



Windwithme would like to share CPU comparison since FX-8120/8150 lanuched.
Originally, I would like to use 3 unlocked CPUs which price is around 200USD to compare.
They are AMD Phenom II X6 1100T, AMD FX-8120 and Intel Core i5-2500K.
For 2500K performance, I have shared many times which you can refer my former reviews.
Moreover, 2500K may make this stage brutally. After consideration, I decided to use AMD only.

AMD Phenom II X6 series, 1090T has the best C/P value.
However, I pick Phenom II X6 1100T due to the price is similar to FX-8120.
1100T packing is all black which meets Black Edition.


Left side is AMD Phenom II X6 1100T.
Right side is original cooler. Black Edition CPU cooler is bigger size and cooper pipe design.
This cooler is same grade as FX-8120.


Before the battle, letís introduce the players.
Left side representative - AMD Phenom II X6 1090T Black Edition
45nm, 6-Cores, official clock is 3.3GHz, TDP 125W
Core name is Thuban and supports Turbo Core to 3.7GHz. L2 is 3MB and L3 is 6MB.

Right side representative - AMD FX-8120.
32nm, 8-Cores、official clock is 3.2GHz
Normal FX-8120 is 125W. This review is using lower power consumption version, TDP is 95W.
Core name is Zambezi and supports Turbo Core to 4.0GHz. L2 is 8MB and L3 is 8MB.


Just judge by spec, FX-8120 manufacturing is more advanced.
FX-8120 has bigger L2 and L3 cache. After sharing to each core, actual L3 is 1MB and L2 is 2 times of 1100T.


I pick AMD current most high end chipset 990FX - GIGABYTE 990FXA-D3.
Using entry 990FX MB can have better C/P.


Blue PCB is standard color of GIGABYTE. This year, they also use black PCB for high end MB to enhance texture.
