What is the difference between these two processors.?

The AMD processor has six cores running at 3.2GHz each, which gives you a total of 19.2GHz of processing power. The Intel processor only has four cores which run at 3.3GHz (3.7GHz with TurboBoost); this gives you a processing power of 13.2GHz (14.8GHz with TurboBoost). As far as value goes, the AMD processor is by far more powerful, and is much less money. The Intel processor takes 95w of power, while the AMD processor takes 125w of power. That isn't a ton of power diference, just a reminder to make sure sure you have the extra 30w in your PSU. The main difference in these two processors is their manufacturers. Intel and AMD are the most notable manufacturers for CPUs. Make sure you pick the right motherboard for whichever processor you purchase; LGA 1155 for the Intel CPU and AM3 for the AMD CPU.
