AMD FX-8120 Vs Intel Core i5-2400

– The FX-8120 is the bulldozer processor from AMD, while the Core i5-2400 is the Sandy Bridge processor form Intel.
– The FX-8120 is an eight  core processor ( going by AMD’s terminology) while the i5-2400 is quad core. Both have the same base clock at 3.1 GHz.

– The FX-8120 has slight edge over the Intel’s i5-2400. The AMD’s lead increases for multithreaded cases.

– The i5-2400. however, comes with HD Graphics 2000 integrated graphics. It does not has great performance but is good enough for encoding and decoding videos and seamless dual displays. You will still need a graphics card for high end gaming.

– FX-8120 as well as the i5-2400 was found to be priced identical at $189.99.

If you can make use of the integrated graphics of i5-2400 ( and you are not into gaming), it is an excellent solution. If you need a graphics card anyway, the bulldozer FX-8120 turns out better, as, it will give you better graphics performance.
