Intel recently expanded its Coffee Lake Refresh processor lineup with integrated graphics-lacking F-series chips, and it seems to have plans for new low-power chips as well.
A mysterious Intel Core i9-9900T has appeared on Yahoo Auctions, and it seems to be a cut-down, 35W version of the original, 95W Intel Core i9-9900K. According to specifications shared on the listing, the Intel Core i9-9900T will still feature identical 8-core and 16-thread as the original CPU, but with severely cut down clock speeds.
