How reliably can turbo be reached? This is where I would love answers from people who own a 6400, or any processor with turbo boost really. Does it require certain workload patterns on the cores? Or, more interestingly for gamers, will it happen if the CPU is loaded but the iGPU is idle? In what circumstances will all cores reach full turbo? It seems odd that it should be possible at all, I always thought turbo boost was for when not all cores were loaded. We see that the 6400 turbo boosts to frequencies just 100 MHz behind the 4460, a far cry from the leap backwards the base clock made it look like. 2.7 GHz is just weak, especially considering its predecessor the i5-4460 was a full 500 MHz faster.īut then I look at the turbo frequencies and things get more interesting CPU At first glance the i5-6400 looks rubbish.
