Taiwanese semiconductor powerhouse TSMC has announced that it has managed to push the ARM Cortex A9 dual core processor to 3.1GHz under what it calls typical conditions for high performance uses.
In mobile computing conditions, TSMC managed to deliver speeds between 1.5GHz and 2GHz and claims that at 3.1GHz, the 28nm dual core processor implemetnation is twice as fast as its counterpart at 40nm under the same operating conditions.
Interestingly ARM quotes TSMC’s 40nm for its standard hard macro implementations, offering either power optimised or performance optimised options.
At 2GHz, a dual core Cortex-A9 typically reaches 10K DMIPS dissipating 1.9W. One can therefore expects under similar conditions the 3.1GHz 28nm-based processor to reach in excess of 15K DMIPS with power dissipation.
It will be interesting to find out how semiconductors partners will implement ARM cores running at such high speeds. Given that power dissipation and consumption is likely to be too high for mobile usage, one can guess that they will be used in desktop-bound computers or mobile products such as tablets or thin format laptops.
