An Intel Xeon E5-2670 gets much higher scores in Passmark than an i5 6600k, does this mean the Xeon will outperform the i5 in gaming?

Xeon only gets higher scores because passmark can take advantage of the extra threads. But in games, higher clockspeeds on a few cores is more important, so no, the xeon will not perform better than the 6600k and will probably be a bit slower.

Xeon is excellent when it comes to hyperthreading unlike the i5 which does not support hyperthreading.So when doing task that makes use of CPU cores like video editing or rendering a xeon will always beat a i5.

In Hyperthreading a single physical CPU Core will will be allotted 2 logical(virtual) cores by the Operating System thus making it appear 2 cores instead of 1 physical cores.The main function of hyper-threading is to increase the number of independent instructions in the pipeline.For example two instruction(code execution) will be performed by each virtual cores as opposed to one code execution by one physical core


i5 does not support Hyperthreading and hence is limited to only by 4 cores while xeon supports hyper threading and if xeon has same core count as i5 i.e 4 then it will support upto 8 virtual core just making processing faster.


However for gaming, Hyper Threading is not beneficial as games rarely use more than 2-3 cores, so the extra hyperthreads are largely irrelevant.

As CTurbo said, the i5 would be better for gaming. The xeon you mentioned is nearly 5 years old and is clocked slower, especially if you plan to overclock the 6600k. The max turbo of the xeon is only 3.3ghz, slower than the base speed of the 6600k. Chances are once a couple cores become fully utilized in the xeon the core speeds will begin dropping to 3.1 or lower, closer to the 2.6ghz base speed. With more cores but behind in ipc and speed it's a similar scenario to comparing a modern i5 to an fx 8350 which suffers from lower ipc despite having more cores.

The 6600k is already 35% faster based on clock speed alone, if overclocked to say 4.5ghz it will likely be 60% faster and that doesn't even factor ipc improvements. That factored in you're probably looking at 70-75% faster at the core level.
