Personal Big Screen: Notebooks
From the diagram above you can clearly see how the processor performance and energy efficiency increase with the time. And we intend to keep the pace up with the introduction of the new Merom processor in H2 of this year. The performance per watt will increase even more in this case. But what will be so different in the upcoming Merom compared to the Yonah? Let’s take a look.
Yonah CPU will boast smart cache technology, which implies that two cores can in an intelligent way access the same cache. Unlike the conventional architecture, where each core has its own cache to access. Another feature of the advanced microprocessor design will be enhanced heat control. Digital thermal sensors enable aggressive system power management. Power control allows turning off the power inactive cache segments. Micro-logic areas inside the core can be switched off when they are not needed.
Merom features from be even more enhanced:
It will also have some new features, such as wide dynamic execution implying wider pipes, deeper buffers, instructions fusion, which I have already mentioned in my first IDF Coverage article. Merom is scheduled to come out in Spring 2006. But today already we could see a few Merom powered notebooks:
According to Intel’s mobile roadmap after that there should arrive the next major platform refresh aka Santa Rosa:
According to Intel, Santa Rosa platform should have a dramatically better microprocessor, faster Generation 4 graphics, IEEE 802.11n MIMO Wi-Fi, professional level manageability and security, Intel Media Share software and Intel NAND technology.
The idea behind NAND Robson technology is to reduce the precious booting time in half. We all know how important it is to have the mobile devices boot up rapidly and come back to life very fast from standby mode. This is what the NAND Robson technology looks like:
Intel performed a very illustrative demonstration of this technology in action so that we could really feel the difference. The system with NAND Robson technology loaded all standard office applications in 3.3 sec compared to 15 sec on a standard system. But faster boot-up is not all. Also wattage consumption is lower, because the applications respond faster thus saving power, which is important as we make these devices smaller and faster.
