Warren East, who has spent the last 12 years as CEO of ARM, has announced that he will retire on July 1. During his time in charge, East has overseen ARM’s processor design powerhouse through some of its most explosive growth, thanks to lucrative deals with companies like Apple, AMD, and Qualcomm.

We got a glimpse of NVIDIA’s new Tegra 4 back in December, when a leaked slide detailing its specifications began circulating the Internet. But the company has now made the impressive chip official at CES 2013 in Las Vegas. Designed for mobile devices like smartphones and tablets, the Tegra 4 boasts a super speedy quad-core Cortex-A15 processor and 72-core graphics, making it the “world’s fastest mobile processor.”

If you’re into benchmarks, you may be interested in the latest results from the Intel powered Santa Clara set to hit France in June. We’re all curious to see how Intel’s new Medfield chips perform and whether or not they will shake up the mobile market as they claim they will. A German blogger recently took the Santa Clara for a spin through Rightware and Vellamo, both of which are browser benchmark tools. Rightware tests the browser’s performance in JavaScript and HTML rendering. The Intel chip performed quite nicely, scoring a 89180 which is slightly better than the iPhone 4S (87801) but still well under the Samsung Galaxy Nexus (98272).

CES will bring out all the big players in the mobile processor game, each ready to flaunt the power, speed, and overall performance of their mobile processing chips. We’re going to give you a look at a few of the major players and what they plan to bring to the CES table. This year’s buzz word should be “quad-core,” and we’re hoping to see plenty of it (hopefully on phones).
