AMD Athlon 860K Black Edition CPU Review
In ADIA64 we see that at stock the last generation 760K actually beats the 860K in almost all the CPU based tests, we believe that this is due to the 760K having a higher clock speed. When we use both CPUs with the ram clocked at 2400MHz we see that the 760K cannot utilize the extra bandwidth and actually has a performance decrease in most tests. The 860K does see an improvement in all scores when using faster memory, showing that AMD has improved the memory controller on the Steamroller CPU.
We see here that overclocking the CPU gives a healthy improvement in all CPU scores.
In the memory tests we see that AMD has made great advancements in their memory controller, with the 860K easily beating the 760K in terms of memory performance at 1866MHz. At memory clocks of 2400MHz we again see that the 760K has an inability to use the additional memory speed and actually has a decrease in it's memory performance, the 860K on the other hand is much more capable of handling higher speed memory with overclocking the CPU northbridge allowing further performance advantages to be gained from using 2400MHz memory.
