Intel Core i7 4770K / Core i5 4670K / Core i5 4430 preview: Haswell test

Intel has introduced its new fourth-generation Core processors, also known as Haswell. The new CPUs will be available at a select few stores, but we can tell you in detail about the performance of Haswell with our comprehensive 49-page review. We took a closer look at the Intel Core i7 4770K, Core i5 4670K and Core i5 4430 processors. The first two are of course the official successors to the Core i7 3770K and Core i5 3570K.

If you've followed the news surrounding Haswell in the past few months, you will already be familiar with the ins and outs of the new processors. In that case, you can go directly to page 13, which is the start of the benchmarks. In the first twelve pages we will go over all of the background info about Haswell.

Intel's familiar tick-tock business strategy keeps on rolling, and Haswell is the next step. When the Core architecture was originally launched along with the Core 2 Duo processors, Intel announced it would release a new product each year. If it released a new architecture one year (tock), the next would see the launch of a new manufacturing process (tick).

While the interval between launches is a bit longer than a year now - about 14 months - the underlying strategy is still there. The most recent introduction was the Ivy Bridge processor on 23 April of this year. This was a so-called "tick", a transition to smaller, 22nm transistors. The architecture of Ivy Bridge is therefore based on the previous generation Sandy Bridge processors, so the performance differences are relatively small.

The new generation, Haswell, is a "tock", a new architecture based on an existing production process. These are generally the more interesting of the two, as the performance increase is usually quite significant. The fourth generation Intel Core appears to be primarily focused on power consumption and efficiency. That's not surprising, considering laptops and other mobile devices are a bigger market than desktops. Haswell will fit into much thinner Ultrabooks and tablets than current Ivy Bridge processors are able to.
