AMD FX-8120 Vs Intel Core i7-2600K

The Table below captures quick and important difference between the AMD’s Bulldozer FX-8120 and the Intel’s Sandy Bridge Core i7-2600K.

The FX-8150 has a street price of $189 while the Core i7-2600K is priced at $324 ( at the time of writing). Is the extra price for the i7-2600K justified ?

Table : AMD FX-8120 Vs Core i7-2600K Feature Differences

Feature AMD FX-8120 Core i7-2600K
Core Frequency 3.10 GHz 3.40 GHz
No. Of Cores 8 4 ( 8 Hyperthreads)
Cache Organization 4 x 2MB L2 and Upto 8 MB L3 8 MB L3 Smart Cache
Turbo Frequency 4.00 GHz ( 4 Cores), 3.40 GHz ( 8 Cores) 3.8 GHz ( with one core)
TDP Rating 125 Watts 95 Watts
64 Bit Support Y Y
Lithography 32 nm 32 nm
Integrated Memory Controller DDR3-1866 DDR3-1333
Integrated Graphics None HD Graphics 3000 Base 850 MHz, Turbo 1.35 GHz

– In CPU performance, the Core i5-2600K has clear edge over the FX-8120, owing to its better architecture.
– The Core i7-2600K, however, comes with integrated graphics ( HD Graphics 3000). Depending upon what you want to do with the graphics, it may or may not be useful for you. If you are not into cutting edge gaming, the HD graphics 3000 is good enough for high resolution display ( including dual displays) as well as encoding and decoding.
– If you have to buy a separate gaming card anyway, the FX-8120 provides a better cost effective option. In the price of Core i7-2600K you get a FX-8150 plus a mid to high end graphics card. You loose a bit of processor performance, but the huge gain with the graphics more than offsets it.

Some more details of AMD FX-8120

The AMD’s FX-8150 is an 8 Core bulldozer processor that will perform great, especially in cases where all 8 of its core can be put into use. It supports Turbo boost and can be overclocked. The bulldoze architecture is based upon modules – with each module having two integer cores. Each of these two core have their own L1 Data Cache.

Some more details of Core i7-2600K

The core i7-2600K is the overclcockable version of the Core i7-2600, which otherwise is has same base frequency. The higher passmark score of the core i7-2600K reflects the fact the people have submitted more overclocked score without mentioning it. This second generation processor is great if you want extreme performance and over clocking ability. Its integrated graphics may be good enough for small to medium end gaming as well as videoencoding and 1080p display.
The clock frequency of the integrated graphics stands at 650 MHz that can ramp to 1.35 GHz. The graphics boost works in tendem with main processor turbo boost, with the intention of keeping the total heat generated in control.
