A little over two weeks ago, Gigabyte accidentally and briefly listed Intel's Coffee Lake Refresh (CFL-R) T-series processors on its website. Nevertheless, the motherboard manufacturer left out the boost clock rates, but respected leaker momomo_us helped us fill in the missing blanks. Biostar also accidentally slipped out some new details on the Pentium Gold and Celeron SKUs, giving us a complete view of the new landscape.

As with any unreleased product, it's good practice to take leaked specifications with a bit of salt. Since Intel hasn't officially announced them, there is still room for tweaking the operating clock speeds.

The Core i9-9900T and Core i7-9700T are the top dogs of the 9th-generation T-series lineup. The first is an octa-core, 16-thread chip that rocks a 2.1GHz base clock and the second is an octa-core, eight-thread part with a 2GHz base clock and 4.3GHz boost clock.

The Core i5 lineup features six cores and six threads. The Core i5-9500T is the highest-clocked model featuring a 2.3GHz base clock and 3.9GHz boost clock. The Core i5-9400T has a 2.2GHz base clock and 3.7GHz boost clock. The Core i5-9400T sports a more moderate 1.8GHz base clock and 3.4GHz boost clock.

The Core i3-9300T and Core i3-9100T are quad-core parts without Hyper-threading. The Core i3-9300T runs at a 3.2GHz base clock, and its boost clock is currently unknown. On the other hand, the Core i3-9100T operates with a 3.1GHz base clock and 3.7GHz boost clock.

At the bottom of the stack, the Pentium Gold G5600T and G5420T come in with two hyper-threaded cores. The G5600T has a 3.3GHz base clock while the G5420T's base clock is 100MHz lower. Lastly, the Celeron G4930T is equipped with two cores and a 3GHz base clock.

Intel could be coming of its 14nm slump very soon. A lot of the 9th-generation desktop chips are back in stock. As a matter of fact, the Intel Core i9-9900K currently tops Amazon's CPU best-seller list. It's possible that Intel could release the new T-series processors as soon as next month. UK retailer Kikatek backs up the theory as the company has listed the Core i9-9900T with a May 15 launch date.
