Hardcore gamers are more interested in raw horsepower than incremental thermal wins, but Intel is still proud to announce that it will release at least one Haswell Core chip that has an SDP of just 4.5 watts. This surpasses the company’s previous mark of 6W SDP, and both are far below Intel’s stated goal a year ago of producing chips under 10W SDP.

It’s important to note, however, that SDP (Scenario Design Point) is not the same as TDP (Thermal Design Power). The latter has been the standard metric for determining the cooling needs of a given processor for some time, and SDP is a different (though related) metric. Thus, for those who have been following the decreasing thermal requirements of Intel chips, it’s important to remember that TDP and SDP are apples-to-oranges comparisons.

Still, it’s quite an achievement on Intel’s part to develop such thermally efficient chips, and these processors will enable more fanless and tablet designs that will have better battery life and can run a full Core chip instead of a mobile Atom processor.

The 4.5W and 6W SDP processors will be available in the second half of this year.

Pretty cool they are catering to fanless design for mobile devices. Interesting to see what new approaches to technology will do for us.


well if intel keeps this up then they could take a strong lead in the mobile space. probably starting with tablets then maybe even move back into smartphones.


Intel could but I just don't see ARM being taken out that quickly. Between ARM and Samsung really for the mobile market. More computing power is always a plus but it seems like Intel is behind the ball trying to catch up.
