Intel Culls High-TDP "Cactus Ridge" Thunderbolt Controller

Intel has reportedly discontinued one of its "Cactus Ridge" family of Thunderbolt controllers, the L3510H. This controller has relatively high TDP of 3.4W, and a low-power part in the same family, the L3510L, already exists. The L3510L has a slightly lower TDP, at 2.8W. The difference may not seem much, but could impact notebook battery life. The L3510 "Cactus Ridge" family consists of 4-channel Thunderbolt controllers, with smaller package-size (12 x 12 mm) compared to the 82523EF "Light Ridge" controller family, with its larger (15 x 15 mm) package sizes. The final samples of "Cactus Ridge" chips will reach customers only by mid-April.

...Didn't even know thunderbolt was out unless they are referring to apple products using it. That seems odd that they got rid of it just because of 1W

It was probably the result of a process shrink. They discontinued the higher nm product for the same reasons 250nm, 130nm, and 90nm processors have been discontinued (offer no advantage and cost more).
