Need advice on CPU (Intel Core i5-4690) and mobo

maikaal · Oct 18, 2014

I know google is your friend but can someone please help - I'm in process of building new PC and my local store has these CPUs:
- Intel Core i5-4690 - 183 EUR
- Intel Core i5-4690 Haswell refresh - 192 EUR

My question is what would I get from Haswell refresh and is it worth those 9 EUR?

Also very important question, please bear with me - does this motherboard support Haswell refresh? - MSI B85I (http://www.msi.com/product/mb/B85I.html#hero-overview)

They are the same CPU, both are haswell refresh! With the correct BIOS the board does http://www.msi.com/support/mb/B85I.html#support-cpu

You listed two identical numbers. Intel never makes different processors with the same number.

There was an i5-4670 Haswell and an i5-4690 Haswell refresh as well as the i5-4690K Devil's Canyon.

The Haswell refresh processor is a small tick faster than the original Haswell processor. The Devil's Canyon processor allows for better overclocking with improved TIM and some other OC-specific features.

For that motherboard, chances are you will need a BIOS refresh - if you are buying from a walk-in store, you should be asking them in the store and understand what support they will be able to give you.

On a related note, why would you buy a modern processor and an ancient chipset motherboard to run it on?

The store has probably erroneously listed the old i5-4670 (Haswell original) as the i5-4690 (Haswell refresh), for 183 EUR

Ask them to show you the cheaper one and if it is the i5-4690, get it for 183 EUR.

As for that motherboard, it will more than likely require a BIOS update in order to work with a Haswell refresh processor. That said, you cannot use the i5-4690 itself to do the update.

So to avoid getting stuck you can either get a Haswell original processor, or select a B97/H97/Z97 chipset motherboard that will work with a Haswell refresh processor out of the box.

Thanks a lot for all your answers. So my store has made a mistake in cpu listing, and I have to spend more on mobo if I want Haswell refresh.

Your store either made a mistake on the listing or on the numbers of the processors, as I explained to you earlier.

Yep yep, most likely it's the same cpu and I can get it for 183 EUR because i5-4670 is listed separately and for cheaper.

maikaal :

Then check of it has the "K" in the number. In that case it's an overclockable i5 Devil's Canyon and you may want to spring for the Z97 motherboard.
