    Zen 2 should be very competitive with the 9900K/KS, while offering FAR better performance per watt and a much lower TDP. Also, in game engines that scale beyond 4 threads, Zen 2 will likely have the upper hand due to a more efficient SMT implementation.

    The biggest reason that Intel has typically been able to dominate AMD over the years in gaming, has to do with the Core series' much lower memory latency more than their clockspeed advantange. Games are typically very sensitive to memory latency more than anything, likely because they are programmed so poorly. That's why AMD decided to double the L3 cache in Zen 2. The doubling of the L3 cache and support for higher frequencies will result in much lower effective memory latency for Zen 2 compared to Zen+, despite no longer having a memory controller directly attached to the core.

    Other nice improvement in Zen 2 is 1:1 clock of memory to IF. Zen(+) had 2:1 clock of memory:IF. (This applies to up to 3.7GHz which is more than most of us can go for with current memories.)
