Nokia N97 still using ARM11 not OMAP 3?

It’s currently unconfirmed, but All About Symbian are reporting that the new Nokia N97 uses the same Texas Instruments ARM11 processor, with a higher clock speed, as the N95, rather than the newer TI OMAP 3 chip. If true, this will come as a disappointment for anyone hoping the new flagship smartphone would take advantage of the OMAP 3’s super-frugal architecture and speedier ARM Cortex core.

Instead, the rumors suggest that the N97 will be “as fast or faster” than the Nokia E71, with the ARM11 chip clocked higher than in previous devices. Although that means it will likely be the quickest Nokia smartphone available, it raises questions about whether the N97 could be considered a MID replacement.

The TI OMAP 3 processor runs at 800MHz but requires just 750mW under load, while in deep sleep mode there’s practically no current draw whatsoever. That means extra-long standby times and the ability to withstand intensive use on a single charge. Nokia are quoting up to 430hrs GSM standby (400hrs WCDMA) or 6.6hrs GSM talktime (5.3hrs WCDMA) for the N97.

TI promise 1-Watt MID with super-frugal OMAP 3 CPU

Texas Instruments are looking to shake up the Mobile Internet Device (MID) segment with a device capable of running the core, display and full connectivity on just 1 Watt of power. The so-called 1-watt MID is part of a presentation by Seshu Madhavapeddy, General Manager of Mobile Internet Devices at TI, who discusses the company’s OMAP 3 platform and how its low-draw and power saving modes [pdf link] all combine to full-day use with current battery technology.

Compared to an x86 chipset such as Intel’s Atom, which requires 3 to 5W in a worst-case power consumption, the TI integrated OMAP 3 processor, at 800 MHz, requires just 750mW. Meanwhile, when the OMAP 3 processor is in deep sleep mode it draws almost no current at all, whereas an x86 based product draws between 80 and 100 mW in power-saving mode.

Combined, that adds up to a TI powered MID that can be used for a full day on a single charge, or alternatively left on standby for a full week without expiring. The company has not given details on when we could expect to see products taking advantage of all these features, but the new Archos PMPs are already using OMAP 3 processors.
