The war for fastest mobile CPU has started whereas some of we still using some old PC of P3 around rang below 1 GHz. Some of manufacturer started their phones with 1GHz and other focusing on 1.5 GHz. Qualcomm's Snapdragon family is probably the household name when it comes to 1GHz mobile CPUs. It's been around for more than a year now, shining initially in the Toshiba TG01, then powering such prominent phones as the HTC HD2, the Nexus One and the HTC EVO 4G.
The Snapdragon's Scorpion core takes care to add better multimedia instructions and power management to the Cortex-A8 core of ARM Holdings.
The next-gen Snapdragons above will be produced with the 45nm technology, but there are actually phones on the market with CPUs that utilize this technology right now. Enter Samsung’s Hummingbird chipset, a SoC which powers the company’s first bada OS phone – the Samsung Wave, and the Galaxy S with its US carrier versions.
1GHz processors on high-end handsets are all the rage now, but 1.5GHz puppies with more than one core have finished sampling and are being shipped to manufacturers. These are already desktop clock speeds, but how much is enough? Will the mobile CPU war fall victim of the same delusion the desktop one had – that faster is better? Or will it try to find the sweet spot between raw power and energy consumption as their laptop counterparts did?
We think the answer will be known sooner rather than later as we've already attained the magic 1GHz number, and the upcoming CPUs promise even higher clock speeds with the same power consumption. Hummingbirds and Snapdragons - these 1GHz animals are offering all-in-one solutions to cell phone manufacturers. Called system-on-a-chip (SoC), they take care of both the system tasks and the hardware video acceleration, often along with all baseband and RF connectivity, the GPS module and the multimedia processing. They are designed to fulfill the longest lasting dream of any electronics user – to carry one device that does it all decently.
