Intel has officially launched Penryn-based dual-core processors for notebooks, but also indicated that users expecting quad-core mobile processors may have to wait until issues surrounding power consumption are resolved.
The company's Core 2 Duo processors will be delivered to laptops based on the Centrino mobile platform and are manufactured using the 45-nanometre process.
Intel's dual-core processors were good enough for notebooks at present as they performed required tasks and did not strain battery life, vice-president and general manager, Intel Mobile Platforms Group, Mooly Eden, said. Quad-core processors had power consumption issues and weren't ideal for laptops yet, he said.
To preserve battery life, the Penryn-based Core 2 Duo processors have an advanced power management state called Deep Power Down Technology, which reduces a processor's power when not functional.
The improved Centrino mobile platform, called Santa Rosa Refresh, will feature the Intel Mobile 965 processor and support for 802.11n. An upgrade to the platform, codenamed Montevina, is due out in the second half of the year and will include Echo Peak, a mini-card that integrates WiMax and Wi-Fi wireless technology on one chip. The new Core 2 Duo processors - the T8100, T8300, T9300 and T9500 - feature 2.10GHz or 2.6GHz clock speed with up to 6MB of shared L2 cache.
Intel also introduced the Core 2 Extreme X9000 processor, which runs at 2.8GHz and has 6MB of shared L2 cache, and new Penryn-based server and desktop processors including the Core 2 Quad quad-core desktop processors.
Intel also released four dual-core desktop processors.
