ARM announces a new Quad-core chip
Chipmaker ARM on Thursday announced a new 2.0 GHz quad-core Cortex A15 processor, which is ready for deployment to power notebooks, ultrabooks or perhaps even tablets.
The Cortex A15 processor architecture, which first appears in 2010, was an attempt by the company to produce a chip that has the frequencies up to 2.5GHz. ARM however has come up with a 2.0 GHz version. Taiwan Semiconductor Manufacturing Company (TSMC) is reported to be fabricating the chip on its 28nm process node. The Cortex-A15 MP4, is clocked at 2.0GHz with performance exceeding 20,000DMIPS.

ARM reports that the implementation dubbed “hard macro” is a process of integration of its NEON single instruction multiple decode and floating point architecture. The chip is aimed to power laptops and high performance, low power network and enterprise devices. In other words the quad-core Cortex A15 will be powering laptops running Microsoft Windows 8 operating system.
“For SoC [system on chip] designers looking to make a trade-off between the flexibility offered by the traditional RTL-based [register-transfer level] SoC development strategy and a rapid time to market, with ensured, benchmarked power, performance and area, an ARM hard macro implementation is an ideal, cost-effective solution. This new Cortex A15 hard macro is an important addition to our portfolio and will enable a wider array of partners to leverage the outstanding capabilities of the Cortex-A15 processor.” Explaines Jim Nicholas, VP of marketing for the processor division of ARM.
ARM has chosen TSMC for the processor optimization which is in effect to optimize ARM architecture to TSMC’s 28nm and 40nm process nodes.

So how is the performance of Cortex-A15 processor? According to Alistair Lowe of hexus.net, the Cortex-A15 MP4 surpasses the performance of the 3.2GHz PowerPC triple-core Xenon which is found on Microsoft’s XBOX 360.
The new chip will undeniably offers attractive choice for entry-level notebook market and perhaps tablets as well.

Generating a very rough comparison against another RISC architecture, at 20,000DMIPS the raw performance of the Cortex-A15 MP4 in fact exceeds the performance of the 3.2GHz PowerPC triple-core Xenon found powering Microsoft’s Xbox 360 and so, it’s easy to see how, with new found support from Windows 8, the ARM architecture could make an appealing choice in the entry-level notebook market.

Wong Chung Wee of HarwareZone.com explained:
The newly launched ARM Cortex-A15 MPCore processor is a hard macro variant quad-core with a rated clock speed of up to 2.0GHz, built using the TSMC 28nm HPM process and offers similar power consumption ratings to their existing Cortex-A9 products. It also includes ARM’s NEON and Floating Point Unit technology, EEC for L1 and L2 RAM, as well as its support for virtualization, which makes it suitable for a wide variety of applications and their virtual environments.[More]
James Trew of engadget.com stated:
The chip variant runs at 2GHz, with performance of over 20,000 DMIPS if you were wondering. Notably, it operates with the same power usage of the A9 hard macro, which should mean it’s got good efficiency credentials, and it’s the first in the family to be based on 28nm process. There’s no indication where we might see this turning up, but with the firm spilling the full details at the IEEE Symposium later this week, we’re sure we’ll find out soon enough. [More]
