AnandTech writes Intel is now discontinuing the dodecahedral packaging in favor of something less cool, but more practical.
Intel launched Comet Lake a couple of weeks ago, its 10th generation Core product, with the flagship i9-10900K sitting at the top of the stack. As the Core i9-9900K no longer sits in that top spot, Intel has decided to discontinue versions of the 9900K in its special packaging. Specifically, retailers have until June 26th to order these processor versions, and the last shipment will be on July 10th. This is a very quick discontinuance procedure, however the non-special retail version will still be available.
