Marvell is sampling a new family of high-performance, ultra-low-power system-on-chips (SoCs) targeting IP-based home gateways, set-top boxes (STBs), home routers, media servers, and mobile Internet devices (MIDs). The Linux-compatible Marvell 88F6000 chips integrate Feroceon cores that clock to 2GHz, and draw 2 Watts, Marvell says.
The Marvell 88F6000 can act as either a main processor or as a co-processor, says Marvell. As a co-processor in set-top boxes and other video rendering equipment, it can offload applications such as GUIs and web browsers from a primary video processor, thereby improving performance.
The 88F6000 SoCs are offered in three progressively more powerful versions: the 88F6180, 88F6192, and the 88F6281. The latter is clockable to 2GHz, while consuming under two Watts, Marvell claims. Each of the "highly-integrated" SoCs comes with I/O including two SATA ports, a USB port, a PCI Express (PCIe) port, and an an SDIO port.
по тепловыделению и энергопотреблению Atom сливает всем ARM(вроде не видел ничего, что бы было хуже Atom), по производительности ... PXA270 конечно слабее, а вот Tegra nvidia еще не видел :) их, возможно можно будет сравнить ...
