Intel has announced the discontinuation of its  9th Gen Coffee Lake Refresh Desktop CPU lineup including the flagship Core i9-9900K. A total of 117 boxed and tray CPU units featured inside Intel's 9th Generation lineup will reach discontinued status this year while the last shipments will be made till December 2021.

Launched as a replacement to the 8th Gen Coffee Lake lineup, the 9th Gen Coffee Lake Refresh CPUs were brought to the market to compete against the AMD Zen+ based Ryzen 2000 CPUs but came with one of the worst core/thread segmentation in Intel's history where they were offering Core i5 CPUs with just 6 cores and 6 threads and Core i7 CPUs with 8 cores and 8 threads. Only the flagship model, the Core i9-9900K retained multi-threading support with 8 cores and 16 threads.
