In the Youtube video hosted by AMD's CEO, Dr. Lisa Su, AMD's Corporate Vice President of Worldwide Marketing, John Taylor, and AMD's Technical Marketing, Robert Hallock, the first Ryzen 3 SKUs that will be launched on July 27th are the Ryzen 3 1300X and the Ryzen 3 1200.
Both of these chips are quad-core parts without SMT support, meaning these will stick to 4-threads. The Ryzen 3 1300X works at 3.5GHz base and 3.7GHz Turbo clocks, while the Ryzen 3 1200 works at 3.1GHz base and 3.5GHz Turbo clocks.
Unfortunately, AMD left out some important details like if these will have the same 8MB of L3 cache, as the Ryzen 5 quad-core parts and if the TDP will be lower than the 65W on the Ryzen 5 parts.
Of course, we still do not have the price either, but we guess that AMD could fit somewhere around US $130 for the Ryzen 3 1300X and US $100 for the Ryzen 3 1200, which should put significant pressure on Intel's Core i3 dual-core Kaby Lake lineup.
