A new energy-efficient Intel Core i9-9900 variant was spotted on Yahoo! Auctions: the i9-9900T, which is listed as an engineering sample, features a TDP of only 35W. Its base frequency is allegedly 1.7GHz, 1.9GHz down from the standard 95W i9-9900K/KF. Pricing, or whether it will even make it to shelves, is up for debate.
The processor listed was said to be an engineering sample (ES). Accompanying photos show a QQC0 identifier on its integrated heatsink (IHS). The Intel Core i9-9900T is expected to be produced under Intel’s 14nm++ process and inherit the Core i9-9900K’s eight cores, 16 threads and 16MB of L3 cache. However, being a T-series chip, it should come with slower clock speeds to earn the 35W TDP (thermal design power) badge.
