  1. A interesting question is the AMD steamroller based APU vs the Pentium without a dGPU. As for the game results... It'll depend on the application/game. Ryzen have more cores and each Ryzen core can do a IPC of 6 for a single clock cycle, 5 sustained in heavily optimized scenarios utilizing both threads or 4 in normal optimized scenario, each Skylake core can do 4 sustained and I think 8 for a single clock cycle in corner cases (we're talking about situations that'll happen next to never even with optimization)? AMDs implementation of SMT is better then Intels in raw throughput (how many IPC you can get from both threads combined) However if you just look at the IPC of a single thread on the core when the other thread isn't eating up resources it seems like Intel is in the lead again. In a situation where the two threads are not being fully utilized and each thread can potentially slot in work in when the other is waiting for data or just waiting for work in the first place then Intels Skylake pentium with SMT should win vs Ryzen 1200, likewise in workloads with low instruction level parallelism, after all if you have a workload where each thread can only do one or two instructions pr cycle then Intels core will easily have enough resources for two threads to match a full core, and it might even have a cross-thread communication advantage since each thread don't have to wait for data to be moved from another core but can find it on the same core. On the other hand, in situations where you have a high level of instruction level parallelism as well as enough thread level parallelism to actually fill up the four cores of the 1200 then it should win. I don't know... It's closer then I like as a AMD fan... But Intel seems to have both a clock cycle advantage and they seem to do slightly better at making all their resources available to just one of the two threads in a core at any one time then AMD is with Ryzen...
