The one in the Wii U, the Xbox 360 (the PS3 was a 7 core), the original Phenom X3 and Phenom II X3, and that's it I think. Oh and any unlocked Phenom II X2 with a single unstable core. Some people even had a 5 core thanks to an unlocked 960T.
What is wrong with having a 3 threads CPU? It's better than a dual core. It's not like HEDT Intel processors aren't failed cheap Xenons right? Or the i5s aren't not so good i7s.
These new i3s should mean the Pentium line should be 2C/4T from now on, which means still awesome value for budget builds. Now why did Intel cut the g4560 if the next arch is weeks away and is going to be pretty much the same as the g4560?
