So in short such a benchmark taxes the memory channel and it may look like CPU throttling when it's just the memory channel is soaked and the CPU can throttle back since it can. As there are priors, I stop here.
While running CineBench my A10 7870K APU throttles as it reaches 35 degrees Celsius thermal margin. The clock speed dials back by 1Ghz at times and this affects my score. From my understanding 35 degrees Celsius (thermal margin) under load isn't that hot. Is there something wrong with my processor??
