i3-6100
- two physical cores
- each core is "hyperthreading" meaning another thread of code can run during the those times the core is waiting for new data from system memory
- not overclockable (in general. It's confusing, and places where you COULD overclock Intel has disabled this in BIOS updates or even in Windows updates which disable the overclock once you boot into W10).
- newer architecture (each core is more efficient if we only compared same frequency etc)
i5-2500K
- as per above, basically it's got four cores and is capable of overclocking. It's older but can pull ahead depending on the game or application mainly because of
a) OVERCLOCKING, and
b) four, true cores.

Assume a 10% overclock that becomes:
- 2086, single
- 7572, total
Other:
1) Must consider other parts, such as CPU Cooler (you need a good one for the i5-2500K, but that money could go towards an i5-6500 or similar CPU)
2) Need higher quality motherboard for i5-2500K as per above point
3) WARRANTY issues? and older tech for i5-2500K setup
4) Cost?
Do you own the i5-2500K setup already?
If so then the i3-6100 isn't a good idea. You're paying for a motherboard, new Windows license, new system memory for only SIMILAR performance (better in some, worse in others)
Summary:
So I can compare performance, but that is not the entire question you are likely asking.
Perhaps this will help get you started.

Agree with all this but if you purchased windows u lock it to your account giving unlimited hardware changes.
2500k overclocked still strong for gaming today as as those benches show its 4 true cores make up for the lower ipc count.

To answer the question more simply:
If the i3-6100 can't be overclocked (as discussed) then the overclocked i5-2500K should roughly match it in performance per core. The i5-2500K has four physical cores though.
So the i3-6100 is the same or WORSE depending on the game.

That's not 'officially' true @photonboy:
https://support.microsoft.com/en-us/help/20530/windows-10-reactivating-after-hardware-change
Provided you're on W10 v1607+, then you can link & reactivate. No issues whether it's OEM/Retail/Free Upgrade (at least in theory). There's still very little research to confirm.
Anyway, to answer the original question:
Removing the 'old tech', 'more efficient' etc arguments - essentially the i3 should outperform the older in single-threaded tasks (day to day tasks, web-browsing etc). It should also win out in games limited to dual-core useage.
The i5 on the other hand - if a game truly utilizes > cores, then the 'true' core aspect of the i5 would see it win out in *most* cases. Even more definitively if overclocked - a luxury the i3 doesn't have.

Yes, i5's will perform better than i3's for gaming.
The Core i5 series of CPU's are generally going to run faster than all of the Core i3 CPU's.
The number being higher doesn't mean it's going to be faster.
6100 < 2500
If you look up Intel's naming convention you would learn that the first number is the generation of that CPU line.
The 6 in the front of the 6100 means it's a 6th generation CPU.
The 2 in front of the 2500 means it's a 2nd generation CPU.
New generation CPU's provide a minimal increase in performance vs the previous generation.
The larger difference in performance comes from going to the next tier for Intel Core processor (upgrading from a i3 to an i5 is better than upgrading from an i3 to a newer generation i3).
4590 > 6400
1. Ignore the first number as it only indicates the generation of CPU.
2. Look at the 3 numbers after to give you an idea of performance. ( 590 is higher than 400 )
After the number there are sometimes letters that indicate various things about the CPU as well. Most commonly a K at the end of the CPU number indicates that the CPU is unlocked and you can easily overclock the CPU in the BIOS.
Breakdown Example: i5 6600K (My current CPU)
1. i5 is better than i3 but not as good as i7
2. 6 is the first number so it's a 6th Gen CPU
3. 600 indicates you can expect it to perform better than the 6400, 4590 and may other CPU's
4. The K at the end means I can increase the CPU's clock frequency with ease in the BIOS.
