Kaby Lake 7700K vs Sandy Bridge 2600K IPC Review

There are many HardOCP readers that are still running Sandy Bridge CPUs and have been waiting with anticipation of one day upgrading to a new system. One of the biggest things asked in the last month is just how the 2600K stacks up against the new 7700K processor. So we got hold of one of our readers 2600K systems and put it to the test.



I am going to handle this review much like we did the Kaby Lake vs Skylake ICP Review. If you are reading this it is highly unlikely that you need much verbiage about the benchmarks and what those represent, so I will keep the chatter to a minimum.
