Intel Core i5-3470 Performance Analysis


Test Setup

 Test Setup

The new Core i5-3470 was tested using Intel’s reference Z77 motherboard - the DZ77GA-70K. The new Ivy Bridge processors have improved official memory support for up to DDR3-1600MHz. And since we have already established the minor performance gains going from DDR3-1333MHz to DDR3-1600MHz, the Core i5-3470 will only be tested at DDR3-1600MHz memory speeds.

For comparison, we’ll be pitting the Core i5-3470 against the the Core i5-2500 and Core i5-2400. These two Sandy Bridge CPUs have the closest clock speeds to the Core i5-3470. With a base frequency of 3.2GHz, the Core i5-3470 comes in right between in the Core i5-2500 and Core i5-2400, which have base clock speeds of 3.3GHz and 3.1GHz respectively. Since we don’t have a Core i5-2500, we’ll be using the Core i5-2500K in our results comparison. The Core i5-2500K is almost identical to the Core i5-2500, except that it has an unlocked CPU multiplier and also the more powerful HD Graphics 3000 GPU as compared to the HD Graphics 2000 on the Core i5-2500/2400 CPUs.

We have also included results of the flagship Core i7-3770K, and previous generation high-end Sandy Bridge-E processors, along with the lone eight-core AMD FX-8150.
