Test Systems

We introduced our new test system and methodology in How We Test Graphics Cards. If you'd like more detail about our general approach, check that piece out.

In this case, only the hardware configuration with CPU, RAM, mainboard, as well as the new cooling system are different, so the summary in table form gives a quick overview of the systems used:

    It will be interesting to see where the prices land once they become available.

    No 1440p benchmarks?
  • nightfader
    No testing at higher than full HD resolutions! MOST high end users if not all are going to be paying the money required for 8700k will alrdy have at least a 1440p monitor why no comparison for that most common resolution.

    Where are the 8600k benchmarks. I really want to see how it holds up against the 7700k & 8700k for gaming.
