When Arctic launched the Alpine 12 Passive earlier this week, we wondered why the company couldn't make it AM4-friendly by simply aligning its mount-holes for the AMD socket. Its answer is the new Alpine Passive AM4. This heatsink is slightly bigger than the Alpine 12 Passive, measuring 99 mm x 99 mm x 70 mm (as opposed to 95 mm x 95 mm x 69 mm), and has rectangular mount holes corresponding to the AM4 socket.

The bump at the base appears to be more pronounced, too. If that's not all, it's also heavier, at 557 g, versus 508 g of the Alpine 12 Passive; and yet, its TDP rating remains unchanged - recommended for 35W TDP chips, with 48W being the thermal limit. Your AMD Ryzen choices matching those requirements, for now, are limited to the Ryzen 3 2200GE and Ryzen 5 2400GE, with their TDP rated bang at 35W. The heatsink features a pre-applied slab of MX-5 compound. The heatsink could be priced around $15, and like its Intel-friendly sibling, is backed by a 6-year warranty.

AMD has disclosed, via a pretty standard addition to their website, the existence of some ill-guarded secrets. The secrets in point are low-power variants of the company's 2000-series APUs, which come and join AMD's lineup with lowered TDPs to increased energy efficiency. The Ryzen 3 2200GE and Ryzen 5 2400GE slot right alongside their previously released counterparts, but have enjoyed some clock tuning (and likely some silicon binning as well) to bring their TDPs down from the 2200 and 2400's 65 W to only 35 W - an impressive feat considering there's no difference, at the execution unit level, on these silicon pieces.
