Hey guys. Ok so last night I asked how much I could overclock the AMD FX-6200 if I had Corsair H70 Watercooling, since then I've been looking YouTube and the likes and people are saying that Intel i5's are better. So my question to everyone here is: which is the best i5 for the money, and what would I be able to OC it to? Thanks :)

The only i5 that you can overclock, sadly, is the i5-3570k. It will easily overclock to 4.4GHz or so... and keep in mind that each core is significantly faster than a comparable AMD core, so it'll happily thrash a 8350 at 5GHz in single or double threaded games.

What about the 2500k?

Usually 4.2GhZ is easy - 4.4-4.5 is doable. Anything past that will increase temps in a hurry. Remember that the i5 is clock for clock more efficient than AMD or even previous Intel offerings.

I'm sorry, yes, of course you can overclock that... but the 3570k doesn't cost much more and gives about 10% gains, clock-for-clock, along with PCIe 3.0 for when that becomes a benefit.

Any i5 without "k" can be overclocked by 400mhz over turbo clock on p67, z68, z77 motherboard.

ex: i5 3470
stock turbo 4 core clock: 3.4 Ghz
oc 4 core clock: 3.8 Ghz
with base clock still at 100 Mhz.

Stock: 3.2 GHz, Turbo: 3.6 GHz, BLCK 100MHz.
Overclocked Turbo, 4.0 GHz.


Fixed it for you. Other than that, you're correct, but there's really not that much point in doing so for so little benefit when a "k" unlocked processor will get you a GHz or more without relying on an unreliable turbo boost.

As strange as it seems a "3.2 ghz" i5 3470 runs at stock, 4 cores workload, on a 3.4Ghz turbo clock , unless the tdp is reached.
The max available multiplier ratio for 4 core is then 38.

It's got a max turbo of 3.6 GHz up from 3.2 stock speeds - overclock that turbo by 400 MHz, and you get 4.0 GHz.
