The new dual-core IVB processors are at the center of the company’s ultrabook plans, and the various OEM partners like Dell, HP, Asus, and Lenovo have readied a full range of product SKUs. Intel’s new dual-core, Hyper-Threaded Ivy Bridge processors retain the same core/thread configuration as their Sandy Bridge-based predecessors. At the upper end of the market, the replacement cycle starts now; Intel delayed the introduction of mobile IVB until now to give OEMs time to clear stocks of older parts. Ivy Bridge’s greatest advantage over Sandy will be in GPU-centric workloads, but the higher clock speed will deliver 12-28% higher CPU performance as well. Interestingly enough, battery life is one area Intel isn’t pushing upwards this refresh. That’s not to say we won’t see Ivy Bridge systems with better battery life, but the company has put its focus on other improvements."
