The L3 can make a considerable difference, particularly in gaming. Take a look:
It's partly the reason why that Trinity CPU would look mediocre in gaming compared to an SB/IB alternative with the same discrete GPUs. That 30% gap in single-threaded performance also doesn't help
😛
I'm not sure where you're getting your IB i3 info (probably the same place you get all of your other info which is quite a mystery to a lot of us), but from what I've seen there hasn't been a release date, never mind clock speeds or what graphics it will have. The only thing we've gotten for the i3 are more delays, which kind of sucks given that I'm hoping to choose between an i3 and a Trinity APU
🙁
