I was running some benches on my 4960X and comparing them to anand when I realized, it seems my 6c/12t have better single core performance than the 5960X. Or at least in synthetic benchmarking.

Is it true, the 5960X a gen later even though they're putting two extra physical cores on, has lesser performance per core? I'd have thought the performance would be similar, if not the 5960X being slightly superior

Well it does have a higher clock speed and a considerably higher turbo boost. The per core performance increase due to the architecture certainly can not make up for that much additional clock speed.

4Ghz for the single core on the 4960k vs 3.5Ghz for the 5960X

Just guessing, but in order to accommodate the extra 2 cores, perhaps they needed to reduced the overall clock speed of the CPU somewhat.

These CPU's aren't really bought for their single thread/core performance, but the combined multi-core performance which is no doubt higher than the 4960X.

So Haswell cores (like those in the 5960X) are somwhere around 5-10% quicker clock-for-clock than Ivy Bridge cores (like those in your 4960X).
Given that, as others have mentioned, your 4960X has an extra 500mhz, which is about 15%, I would expect it to be somewhere between 5 & 10% faster than a 5960X for single threaded tasks.

I believe if you have adequate cooling, they both overclock to similar levels, so in theory an OC'd 5960X would be a little quicker than a 4960X on average. Though there you're at the mercy of the silicon lottery so all bets are off.

But yes, out of the box, a 4960X will outperform a 5960X unless the workload can utilise the additional cores on the latter.
